Rocchetta Mattei. Rocchetta Mattei is a fortress located on the Northern Apennine Mountains, on a hill which is 407 meters above sea level, in the locality of Savignano in the municipality of Grizzana Morandi, on the Strada Statale 64 Porrettana, in the Metropolitan City of Bologna.Built in the second half of nineteenth century, it blends various eclectic styles, from Medieval to Moorish.## History.Rocchetta Mattei was the home of count Cesare Mattei, a scholar, politician and self-taught physician who founded electrohomeopathy, a practice founded on homeopathy.On November 5, 1850, the first stone of Rocchetta Mattei was laid, and as early as 1859 it.

Rocchetta Mattei. became habitable and eventually Cesare Mattei’s permanent residence. Inside Rocchetta Mattei, the count led a life as a medieval castellan and even created a court, complete with a buffoon.The castle hosted illustrious individuals who came from everywhere to undergo Mattei's treatment, including Ludwig III of Bavaria and Alexander II of Russia. In 1925, there was an official visit by the Prince of Piedmont. Even Fyodor Dostoevsky quotes the Count in "The Brothers Karamazov", when he tells the devil he managed to recover from terrible rheumatism thanks to a book and some drops from Count Mattei.## After World War II.During World.

Many initiatives were launched, such as a human chain around Rocchetta Mattei and conferences and debates, which were very successful.In 2000, a museum was established about Count Cesare Mattei, the Rocchetta Mattei, and electrohomeopathy on Via Nazionale 117 in Riola di Vergato, seat of the Committee "Archivio Museo.

Having fallen into the hands of the Bolognese, and created a more advanced defensive line, the fortress became useless and was destroyed in 1293.Before choosing Savignano for its castle, it seems that Cesare Mattei had visited several places. The place was preferred for many reasons: the ease of access, the rock forming a gigantic natural pedestal, and the location on the confluence of the rivers Limentra orientale and Reno. The predominant style of the building is Moorish, with additional medieval and modern Italian architecture.The main entrance opens onto a.

An inscription at the top commemorates the origin and completion of the building with the following words:A large and spacious staircase leads to the vestibule of the main living area. A hippogriff is guarding the entrance, through which one passes into a courtyard dug into the rock. Two caryatids support the jamb of the front door. The monolith basin that occupies the center comes from the parish church of Verzuno where it served as a baptismal font. Entering the courtyard, in the left corner, Cesare Mattei laid the first stone of the building in November 5,.

The staircase of the tower leads through a drawbridge to a small room with small windows and a stalactite ceiling, which was the bedroom of Count Cesare Mattei. Here, the original furniture and pipes owned by the count are still preserved. There is also the ‘Vision’s Staircase’ (Scala delle visioni) which is allegorical depiction in the vault representing the new homeopathic science winning over traditional medicine. Two couplets.

Returning to the Loggia Carolina is the White Room and the Turkish Room. After a short stretch of uncovered rock, there is the Courtyard of the Lions, a reproduction of the courtyard of the Alhambra in Granada. The remains of Cesare Mattei are found inside an ark covered with majolica.Going back from the Courtyard of the Lions one enters the hall of peace, named so in homage to the victorious end.

Rye. northern China.Production levels of rye have fallen since 1992 in most of the producing nations, . For instance, production of rye in Russia fell from 13.9 (e6t) in 1992 to 2.4 (e6t) in 2020. Corresponding figures for other countries are as follows: Polandfalling from 4.0 (Mt) in 1992 to 2.9 (Mt) in 2020; Belarusfalling from 3.1 (Mt) in 1992 to 1.1 (Mt) in 2020; Chinafalling from 1.7 (Mt) in 1992 to 0.5 (Mt) in 2020. However, production levels rose in Germany from 2.4 (Mt) in 1992 to 3.5 (Mt) in 2020.World trade of rye is low compared with other grains.

By 2004, sea otters had repopulated all of their former habitat in these areas, with an estimated total population of about 27,000. Of these, about 19,000 are at the Kurils, 2,000 to 3,500 at Kamchatka and another 5,000 to 5,500 at the Commander Islands. Growth has slowed slightly, suggesting the numbers are reaching carrying capacity.## British Columbia.Along the North American coast south of Alaska, the sea otter's range is discontinuous.

However, the population increased markedly from 2015 to 2016, with the United States Geological Survey (USGS) California sea otter survey 3-year average reaching 3,272 in 2016, the first time it exceeded the threshold for delisting from the Endangered Species Act (ESA). If populations continued to grow and ESA delisting occurred, southern sea otters would still be fully protected by state regulations and the Marine Mammal Protection Act, which set higher thresholds for protection, at approximately 8,400 individuals. However, ESA delisting seems unlikely due to a precipitous population decline recorded in.

Emperor penguin. The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species and is endemic to Antarctica. The male and female are similar in plumage and size, reaching 100 (cm) in length and weighing from 22 to 45 (kg). Feathers of the head and back are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches.Like all penguins it is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat. Its diet consists primarily of fish, but also includes crustaceans, such as krill, and cephalopods, such as.

Emperor penguin. five other penguin species. Forster may have been the first person to see the penguins in 1773–74, when he recorded a sighting of what he believed was the similar king penguin ("A. patagonicus") but given the location, may very well have been "A. forsteri".Together with the king penguin, the emperor penguin is one of two extant species in the genus "Aptenodytes". Fossil evidence of a third species—Ridgen's penguin ("A. ridgeni")—has been found in fossil records from the late Pliocene, about three million years ago, in New Zealand. Studies of penguin behaviour and genetics have proposed that the genus "Aptenodytes" is.

Gingham. Gingham, also called Vichy check, is a medium-weight balanced plain-woven fabric typically with striped, check or plaid duotone patterns, in bright colour and in white made from dyed cotton or cotton-blend yarns. It is made of carded, medium or fine yarns.## History.The name may originate . Alternatively, it is speculated that the fabric now known as "gingham" may have been made at Guingamp, a town in Brittany, France, and that the fabric may be named after the town. Some sources say that the name came into English via Dutch. When originally imported into Europe in the 17th century, gingham was.

Gingham. a striped fabric, though now it is distinguished by its checkered pattern. From the mid-18th century, when it was being produced in the mills of Manchester, England, it started to be woven into checked or plaid patterns (often blue and white). Checked gingham became more common over time, though striped gingham was still available in the late Victorian period. The equivalent in the French language is the noun "vichy", from the town of Vichy in France.

Amanita muscaria. Amanita muscaria, commonly known as the fly agaric or fly amanita, is a basidiomycete of the genus "Amanita". It is also a muscimol mushroom. Native throughout the temperate and boreal regions of the Northern Hemisphere, "Amanita muscaria" has been unintentionally introduced to many countries in the Southern Hemisphere, generally as a symbiont with pine and birch plantations, and is now a true cosmopolitan species. It associates with various deciduous and coniferous trees.Arguably the most iconic toadstool species, the fly agaric is a large white-gilled, white-spotted, usually red mushroom, and is one of the most recognizable and widely encountered in popular.

Amanita muscaria. culture, including in video games—e.g., the extensive use of a recognizable "Amanita muscaria" in the Mario franchise and its Super Mushroom power up—and television—e.g., the houses in The Smurfs franchise.Despite its easily distinguishable features, "Amanita muscaria" is a fungus with several known variations, or subspecies. These subspecies are slightly different, some having yellow or white caps, but they are all usually called fly agarics, and they are most of the time recognizable by their notable white spots. Recent DNA fungi research, however, has shown that some of these variations are not the same species at all, such as the peach-colored.

Amanita muscaria. fly agaric ("Amanita persicina") for example, but the common name 'fly agaric' clings on.Although poisonous, death due to poisoning from "A. muscaria" ingestion is quite rare. Parboiling twice with water draining weakens its toxicity and breaks down the mushroom's psychoactive substances; it is eaten in parts of Europe, Asia, and North America. All "Amanita muscaria" varieties, but in particular "A. muscaria" var. "muscaria", are noted for their hallucinogenic properties, with the main psychoactive constituents being the neurotoxins ibotenic acid and muscimol. A local variety of the mushroom was used as an intoxicant and entheogen by the indigenous peoples of Siberia.

Amanita muscaria. and by the Sámi, and has a religious significance in these cultures. There has been much speculation on possible traditional use of this mushroom as an intoxicant in other places such as the Middle East, Eurasia, North America, and Scandinavia.## Taxonomy and naming.The name of the mushroom in many European languages is thought to derive from its use as an insecticide when sprinkled in milk. This practice has been recorded from Germanic- and Slavic-speaking parts of Europe, as well as the Vosges region and pockets elsewhere in France, and Romania. Albertus Magnus was the first to record it in his.

Amanita muscaria. work "De vegetabilibus" some time before 1256, commenting "vocatur fungus muscarum, eo quod in lacte pulverizatus interficit muscas", "it is called the fly mushroom because it is powdered in milk to kill flies."The 16th-century Flemish botanist Carolus Clusius traced the practice of sprinkling it into milk to Frankfurt in Germany, while Carl Linnaeus, the "father of taxonomy", reported it from Småland in southern Sweden, where he had lived as a child. He described it in volume two of his "Species Plantarum" in 1753, giving it the name "Agaricus muscarius", the specific epithet deriving from Latin "musca" meaning "fly". It gained.

Amanita muscaria. its current name in 1783, when placed in the genus "Amanita" by Jean-Baptiste Lamarck, a name sanctioned in 1821 by the "father of mycology", Swedish naturalist Elias Magnus Fries. The starting date for all the mycota had been set by general agreement as January 1, 1821, the date of Fries's work, and so the full name was then "Amanita muscaria" (L.:Fr.) Hook. The 1987 edition of the International Code of Botanical Nomenclature changed the rules on the starting date and primary work for names of fungi, and names can now be considered valid as far back as May 1, 1753,.

Amanita muscaria. the date of publication of Linnaeus's work. Hence, Linnaeus and Lamarck are now taken as the namers of "Amanita muscaria" (L.) Lam..The English mycologist John Ramsbottom reported that "Amanita muscaria" was used for getting rid of bugs in England and Sweden, and "bug agaric" was an old alternative name for the species. French mycologist Pierre Bulliard reported having tried without success to replicate its fly-killing properties in his work "" (1784), and proposed a new binomial name "Agaricus pseudo-aurantiacus" because of this. One compound isolated from the fungus is 1,3-diolein (1,3-di(cis-9-octadecenoyl)glycerol), which attracts insects.It has been hypothesised that the flies.

Amanita muscaria. intentionally seek out the fly agaric for its intoxicating properties.An alternative derivation proposes that the term "fly-" refers not to insects as such but rather the delirium resulting from consumption of the fungus. This is based on the medieval belief that flies could enter a person's head and cause mental illness. Several regional names appear to be linked with this connotation, meaning the "mad" or "fool's" version of the highly regarded edible mushroom "Amanita caesarea". Hence there is ' "mad oriol" in Catalan, "mujolo folo" from Toulouse, ' from the Aveyron department in Southern France, "" from Trentino in Italy.

Amanita muscaria. A local dialect name in Fribourg in Switzerland is "tsapi de diablhou", which translates as "Devil's hat".## Classification."Amanita muscaria" is the type species of the genus. By extension, it is also the type species of "Amanita" subgenus "Amanita", as well as section "Amanita" within this subgenus. "Amanita" subgenus "Amanita" includes all "Amanita" with inamyloid spores. "Amanita" section "Amanita" includes the species with patchy universal veil remnants, including a volva that is reduced to a series of concentric rings, and the veil remnants on the cap to a series of patches or warts. Most species in this group also have a.

Amanita muscaria. bulbous base. "Amanita" section "Amanita" consists of "A. muscaria" and its close relatives, including "A. pantherina" (the panther cap), "A. gemmata", "A. farinosa", and "A. xanthocephala". Modern fungal taxonomists have classified "Amanita muscaria" and its allies this way based on gross morphology and spore inamyloidy. Two recent molecular phylogenetic studies have confirmed this classification as natural.## Controversy."Amanita muscaria" varies considerably in its morphology, and many authorities recognize several subspecies or varieties within the species. In "The Agaricales in Modern Taxonomy", German mycologist Rolf Singer listed three subspecies, though without description: "A. muscaria" ssp. "muscaria", "A. muscaria" ssp. "americana", and "A.

Amanita muscaria. muscaria" ssp. "flavivolvata".However, a 2006 molecular phylogenetic study of different regional populations of "A. muscaria" by mycologist József Geml and colleagues found three distinct clades within this species representing, roughly, Eurasian, Eurasian "subalpine", and North American populations. Specimens belonging to all three clades have been found in Alaska; this has led to the hypothesis that this was the centre of diversification for this species. The study also looked at four named varieties of the species: var. "alba", var. "flavivolvata", var. "formosa" (including var. "guessowii"), and var. "regalis" from both areas. All four varieties were found within both the Eurasian and.

Amanita muscaria. North American clades, evidence that these morphological forms are polymorphisms rather than distinct subspecies or varieties. Further molecular study by Geml and colleagues published in 2008 show that these three genetic groups, plus a fourth associated with oak–hickory–pine forest in the southeastern United States and two more on Santa Cruz Island in California, are delineated from each other enough genetically to be considered separate species. Thus "A. muscaria" as it stands currently is, evidently, a species complex. The complex also includes at least three other closely related taxa that are currently regarded as species: "A. breckonii" is a buff-capped mushroom.

Amanita muscaria. associated with conifers from the Pacific Northwest, and the brown-capped "A. gioiosa" and "A. heterochroma" from the Mediterranean Basin and from Sardinia respectively. Both of these last two are found with "Eucalyptus" and "Cistus" trees, and it is unclear whether they are native or introduced from Australia."Amanitaceae.org" lists four varieties , but says that they will be segregated into their own taxa "in the near future". They are:## Description.A large, conspicuous mushroom, "Amanita muscaria" is generally common and numerous where it grows, and is often found in groups with basidiocarps in all stages of development.Fly agaric fruiting bodies emerge from.

Amanita muscaria. the soil looking like white eggs. After emerging from the ground, the cap is covered with numerous small white to yellow pyramid-shaped warts. These are remnants of the universal veil, a membrane that encloses the entire mushroom when it is still very young. Dissecting the mushroom at this stage reveals a characteristic yellowish layer of skin under the veil, which helps identification. As the fungus grows, the red colour appears through the broken veil and the warts become less prominent; they do not change in size, but are reduced relative to the expanding skin area. The cap changes from globose.

Amanita muscaria. to hemispherical, and finally to plate-like and flat in mature specimens. Fully grown, the bright red cap is usually around 8 – 20 (cm) in diameter, although larger specimens have been found. The red colour may fade after rain and in older mushrooms.The free gills are white, as is the spore print. The oval spores measure 9–13 by 6.5–9 μm; they do not turn blue with the application of iodine. The stipe is white, 5 – 20 (cm) high by 1 – 2 (cm) wide, and has the slightly brittle, fibrous texture typical of many large mushrooms. At the base.

Amanita muscaria. is a bulb that bears universal veil remnants in the form of two to four distinct rings or ruffs. Between the basal universal veil remnants and gills are remnants of the partial veil (which covers the gills during development) in the form of a white ring. It can be quite wide and flaccid with age. There is generally no associated smell other than a mild earthiness.Although very distinctive in appearance, the fly agaric has been mistaken for other yellow to red mushroom species in the Americas, such as "Armillaria" cf. "mellea" and the edible "Amanita basii"—a Mexican species similar to.

Amanita muscaria. "A. caesarea" of Europe. Poison control centres in the U.S. and Canada have become aware that (Spanish for 'yellow') is a common name for the "A. caesarea"-like species in Mexico. "Amanita caesarea" is distinguished by its entirely orange to red cap, which lacks the numerous white warty spots of the fly agaric. Furthermore, the stem, gills and ring of "A. caesarea" are bright yellow, not white. The volva is a distinct white bag, not broken into scales. In Australia, the introduced fly agaric may be confused with the native vermilion grisette ("Amanita xanthocephala"), which grows in association with eucalypts. The.

Amanita muscaria. latter species generally lacks the white warts of "A. muscaria" and bears no ring.## Distribution and habitat."Amanita muscaria" is a cosmopolitan mushroom, native to conifer and deciduous woodlands throughout the temperate and boreal regions of the Northern Hemisphere, including higher elevations of warmer latitudes in regions such as Hindu Kush, the Mediterranean and also Central America. A recent molecular study proposes that it had an ancestral origin in the Siberian–Beringian region in the Tertiary period, before radiating outwards across Asia, Europe and North America. The season for fruiting varies in different climates: fruiting occurs in summer and autumn across most.

Amanita muscaria. of North America, but later in autumn and early winter on the Pacific coast. This species is often found in similar locations to "Boletus edulis", and may appear in fairy rings. Conveyed with pine seedlings, it has been widely transported into the southern hemisphere, including Australia, New Zealand, South Africa and South America, where it can be found in the southern Brazilian states of Paraná and Rio Grande do Sul.Ectomycorrhizal, "Amanita muscaria" forms symbiotic relationships with many trees, including pine, oak, spruce, fir, birch, and cedar. Commonly seen under introduced trees, "A. muscaria" is the fungal equivalent of a weed.

Amanita muscaria. in New Zealand, Tasmania and Victoria, forming new associations with southern beech ("Nothofagus"). The species is also invading a rainforest in Australia, where it may be displacing the native species. It appears to be spreading northwards, with recent reports placing it near Port Macquarie on the New South Wales north coast. It was recorded under silver birch ("Betula pendula") in Manjimup, Western Australia in 2010. Although it has apparently not spread to eucalypts in Australia, it has been recorded associating with them in Portugal. Commonly found throughout the great Southern region of western Australia, it is regularly found growing on.

Amanita muscaria. Pinus radiata.## Toxicity."Amanita muscaria" poisoning has occurred in young children and in people who ingested the mushrooms for a hallucinogenic experience. Occasionally it has been ingested in error, because immature button forms resemble puffballs. The white spots sometimes wash away during heavy rain and the mushrooms then may appear to be the edible "A. caesarea"."Amanita muscaria" contains several biologically active agents, at least one of which, muscimol, is known to be psychoactive. Ibotenic acid, a neurotoxin, serves as a prodrug to muscimol, with a small amount likely converting to muscimol after ingestion. An active dose in adults is approximately 6.

Amanita muscaria. mg muscimol or 30 to 60 mg ibotenic acid; this is typically about the amount found in one cap of "Amanita muscaria". The amount and ratio of chemical compounds per mushroom varies widely from region to region and season to season, which can further confuse the issue. Spring and summer mushrooms have been reported to contain up to 10 times more ibotenic acid and muscimol than autumn fruitings.Deaths from this fungus "A. muscaria" have been reported in historical journal articles and newspaper reports, but with modern medical treatment, fatal poisoning from ingesting this mushroom is extremely rare. Many books list.

Amanita muscaria. "Amanita muscaria" as deadly, but according to David Arora, this is an error that implies the mushroom is far more toxic than it is. Furthermore, The North American Mycological Association has stated that there were "no reliably documented cases of death from toxins in these mushrooms in the past 100 years".The active constituents of this species are water-soluble, and boiling and then discarding the cooking water at least partly detoxifies "A. muscaria". Drying may increase potency, as the process facilitates the conversion of ibotenic acid to the more potent muscimol. According to some sources, once detoxified, the mushroom becomes edible.

Amanita muscaria. Dr Patrick Harding describes the Sami custom of processing the fly agaric through reindeer.## Pharmacology.Muscarine, discovered in 1869, was long thought to be the active hallucinogenic agent in "A. muscaria". Muscarine binds with muscarinic acetylcholine receptors leading to the excitation of neurons bearing these receptors. The levels of muscarine in "Amanita muscaria" are minute when compared with other poisonous fungi such as "Inosperma erubescens", the small white "Clitocybe" species "C. dealbata" and "C. rivulosa". The level of muscarine in "A. muscaria" is too low to play a role in the symptoms of poisoning.The major toxins involved in "A. muscaria" poisoning.

Amanita muscaria. are muscimol (3-hydroxy-5-aminomethyl-1-isoxazole, an unsaturated cyclic hydroxamic acid) and the related amino acid ibotenic acid. Muscimol is the product of the decarboxylation (usually by drying) of ibotenic acid. Muscimol and ibotenic acid were discovered in the mid-20th century. Researchers in England, Japan, and Switzerland showed that the effects produced were due mainly to ibotenic acid and muscimol, not muscarine. These toxins are not distributed uniformly in the mushroom. Most are detected in the cap of the fruit, a moderate amount in the base, with the smallest amount in the stalk. Quite rapidly, between 20 and 90 minutes after ingestion, a.

Amanita muscaria. substantial fraction of ibotenic acid is excreted unmetabolised in the urine of the consumer. Almost no muscimol is excreted when pure ibotenic acid is eaten, but muscimol is detectable in the urine after eating "A. muscaria", which contains both ibotenic acid and muscimol.Ibotenic acid and muscimol are structurally related to each other and to two major neurotransmitters of the central nervous system: glutamic acid and GABA respectively. Ibotenic acid and muscimol act like these neurotransmitters, muscimol being a potent GABAA agonist, while ibotenic acid is an agonist of NMDA glutamate receptors and certain metabotropic glutamate receptors which are involved in.

Amanita muscaria. the control of neuronal activity. It is these interactions which are thought to cause the psychoactive effects found in intoxication.Muscazone is another compound that has more recently been isolated from European specimens of the fly agaric. It is a product of the breakdown of ibotenic acid by ultra-violet radiation. Muscazone is of minor pharmacological activity compared with the other agents. "Amanita muscaria" and related species are known as effective bioaccumulators of vanadium; some species concentrate vanadium to levels of up to 400 times those typically found in plants. Vanadium is present in fruit-bodies as an organometallic compound called amavadine. The.

Amanita muscaria. biological importance of the accumulation process is unknown.## Symptoms.Fly agarics are best known for the unpredictability of their effects. Depending on habitat and the amount ingested per body weight, effects can range from mild nausea and twitching to drowsiness, cholinergic crisis-like effects (low blood pressure, sweating and salivation), auditory and visual distortions, mood changes, euphoria, relaxation, ataxia, and loss of equilibrium (like with tetanus.)In cases of serious poisoning the mushroom causes delirium, somewhat similar in effect to anticholinergic poisoning (such as that caused by "Datura stramonium"), characterised by bouts of marked agitation with confusion, hallucinations, and irritability followed by periods.

Amanita muscaria. of central nervous system depression. Seizures and coma may also occur in severe poisonings. Symptoms typically appear after around 30 to 90 minutes and peak within three hours, but certain effects can last for several days. In the majority of cases recovery is complete within 12 to 24 hours. The effect is highly variable between individuals, with similar doses potentially causing quite different reactions. Some people suffering intoxication have exhibited headaches up to ten hours afterwards. Retrograde amnesia and somnolence can result following recovery, although never easy.## Treatment.Medical attention should be sought in cases of suspected poisoning. If the delay.

Amanita muscaria. between ingestion and treatment is less than four hours, activated charcoal is given. Gastric lavage can be considered if the patient presents within one hour of ingestion. Inducing vomiting with syrup of ipecac is no longer recommended in any poisoning situation.There is no antidote, and supportive care is the mainstay of further treatment for intoxication. Though sometimes referred to as a deliriant and while muscarine was first isolated from "A. muscaria" and as such is its namesake, muscimol does not have action, either as an agonist or antagonist, at the muscarinic acetylcholine receptor site, and therefore atropine or physostigmine as.

Amanita muscaria. an antidote is not recommended. If a patient is delirious or agitated, this can usually be treated by reassurance and, if necessary, physical restraints. A benzodiazepine such as diazepam or lorazepam can be used to control combativeness, agitation, muscular overactivity, and seizures. Only small doses should be used, as they may worsen the respiratory depressant effects of muscimol. Recurrent vomiting is rare, but if present may lead to fluid and electrolyte imbalances; intravenous rehydration or electrolyte replacement may be required. Serious cases may develop loss of consciousness or coma, and may need intubation and artificial ventilation. Hemodialysis can remove the.

With modern medical treatment the prognosis is typically good following supportive treatment.## Psychoactive use.The wide range of psychoactive effects have been variously described as depressant, sedative-hypnotic, psychedelic, dissociative, or deliriant; paradoxical effects such as stimulation may occur however. Perceptual phenomena such as synesthesia, macropsia, and micropsia may occur; the latter two effects may occur either simultaneously or alternatingly, as part of Alice in Wonderland syndrome, collectively known as dysmetropsia, along with related distortions pelopsia and teleopsia. Some users report lucid dreaming under the influence of its hypnotic effects. Unlike "Psilocybe cubensis", "A.

Amanita muscaria. muscaria" cannot be commercially cultivated, due to its mycorrhizal relationship with the roots of pine trees. However, following the outlawing of psilocybin mushrooms in the United Kingdom in 2006, the sale of the still legal "A. muscaria" began increasing.Professor Marija Gimbutienė, a renowned Lithuanian historian, reported to R. Gordon Wasson on the use of this mushroom in Lithuania. In remote areas of Lithuania, "Amanita muscaria" has been consumed at wedding feasts, in which mushrooms were mixed with vodka. The professor also reported that the Lithuanians used to export "A. muscaria" to the Sami in the Far North for use in.

Amanita muscaria. shamanic rituals. The Lithuanian festivities are the only report that Wasson received of ingestion of fly agaric for religious use in Eastern Europe.## Siberia."Amanita muscaria" was widely used as an entheogen by many of the indigenous peoples of Siberia. Its use was known among almost all of the Uralic-speaking peoples of western Siberia and the Paleosiberian-speaking peoples of the Russian Far East. There are only isolated reports of "A. muscaria" use among the Tungusic and Turkic peoples of central Siberia and it is believed that on the whole entheogenic use of "A. muscaria" was not practised by these peoples. In.

Amanita muscaria. western Siberia, the use of "A. muscaria" was restricted to shamans, who used it as an alternative method of achieving a trance state. (Normally, Siberian shamans achieve trance by prolonged drumming and dancing.) In eastern Siberia, "A. muscaria" was used by both shamans and laypeople alike, and was used recreationally as well as religiously. In eastern Siberia, the shaman would take the mushrooms, and others would drink his urine. This urine, still containing psychoactive elements, may be more potent than the "A. muscaria" mushrooms with fewer negative effects such as sweating and twitching, suggesting that the initial user may act.

Amanita muscaria. as a screening filter for other components in the mushroom.The Koryak of eastern Siberia have a story about the fly agaric ("wapaq") which enabled Big Raven to carry a whale to its home. In the story, the deity "Vahiyinin" ("Existence") spat onto earth, and his spittle became the "wapaq", and his saliva becomes the warts. After experiencing the power of the "wapaq", Raven was so exhilarated that he told it to grow forever on earth so his children, the people, could learn from it. Among the Koryaks, one report said that the poor would consume the urine of the wealthy,.

Amanita muscaria. who could afford to buy the mushrooms. It was reported that the local reindeer would often follow an individual intoxicated by the muscimol mushroom, and if said individual were to urinate in snow the reindeer would become similarly intoxicated and the Koryak people's would use the drunken state of the reindeer to more easily rope and hunt them.## Other reports of use.The Finnish historian T. I. Itkonen mentions that "A. muscaria" was once used among the Sami people: sorcerers in Inari would consume fly agarics with seven spots. In 1979, Said Gholam Mochtar and Hartmut Geerken published an article in.

Amanita muscaria. which they claimed to have discovered a tradition of medicinal and recreational use of this mushroom among a Parachi-speaking group in Afghanistan. There are also unconfirmed reports of religious use of "A. muscaria" among two Subarctic Native American tribes. Ojibwa ethnobotanist Keewaydinoquay Peschel reported its use among her people, where it was known as (an abbreviation of the name "oshtimisk wajashkwedo" (= "red-top mushroom")). This information was enthusiastically received by Wasson, although evidence from other sources was lacking. There is also one account of a Euro-American who claims to have been initiated into traditional Tlicho use of "Amanita muscaria". The.

Amanita muscaria. flying reindeer of Santa Claus, who is called Joulupukki in Finland, could symbolize the use of "A. muscaria" by Sámi shamans.## Vikings.The notion that Vikings used "A. muscaria" to produce their berserker rages was first suggested by the Swedish professor Samuel Ödmann in 1784. Ödmann based his theories on reports about the use of fly agaric among Siberian shamans. The notion has become widespread since the 19th century, but no contemporary sources mention this use or anything similar in their description of berserkers. Muscimol is generally a mild relaxant, but it can create a range of different reactions within a.

Amanita muscaria. group of people. It is possible that it could make a person angry, or cause them to be "very jolly or sad, jump about, dance, sing or give way to great fright". Comparative analysis of symptoms have, however, since shown "Hyoscyamus niger" to be a better fit to the state that characterises the berserker rage.## Fly trap."Amanita muscaria" is traditionally used for catching flies possibly due to its content of ibotenic acid and muscimol.Recently, an analysis of nine different methods for preparing "A. muscaria" for catching flies in Slovenia have shown that the release of ibotenic acid and muscimol did.

Amanita muscaria. not depend on the solvent (milk or water) and that thermal and mechanical processing led to faster extraction of ibotenic acid and muscimol.## In religion.## Soma.In 1968, R. Gordon Wasson proposed that "A. muscaria" was the "soma" talked about in the Rigveda of India, a claim which received widespread publicity and popular support at the time. He noted that descriptions of "Soma" omitted any description of roots, stems or seeds, which suggested a mushroom, and used the adjective "hári" "dazzling" or "flaming" which the author interprets as meaning red. One line described men urinating "Soma"; this recalled the practice of.

Amanita muscaria. recycling urine in Siberia. Soma is mentioned as coming "from the mountains", which Wasson interpreted as the mushroom having been brought in with the Aryan migrants from the north. Indian scholars Santosh Kumar Dash and Sachinanda Padhy pointed out that both eating of mushrooms and drinking of urine were proscribed, using as a source the "Manusmṛti".In 1971, Vedic scholar John Brough from Cambridge University rejected Wasson's theory and noted that the language was too vague to determine a description of Soma. In his 1976 survey, "Hallucinogens and Culture", anthropologist Peter T. Furst evaluated the evidence for and against the identification.

Amanita muscaria. of the fly agaric mushroom as the Vedic Soma, concluding cautiously in its favour. Kevin Feeney and Trent Austin compared the references in the Vedas with the filtering mechanisms in the preparation of Amanita muscaria and published findings supporting the proposal that fly-agaric mushrooms could be a likely candidate for the sacrament. Other proposed candidates include "Psilocybe cubensis", "Peganum harmala," and "Ephedra."## Speculated role in Christianity.While far from widely accepted, philologist, archaeologist, and Dead Sea Scrolls scholar John Marco Allegro postulated that early Christian theology was derived from a fertility cult revolving around the entheogenic consumption of "A. muscaria" in.

Amanita muscaria. his 1970 book "The Sacred Mushroom and the Cross." This theory has found little support by scholars outside the field of ethnomycology. The book was widely criticized by academics and theologians, including Sir Godfrey Driver, Emeritus Professor of Semitic Philology at Oxford University and Henry Chadwick, the Dean of Christ Church, Oxford. Christian author John C. King wrote a detailed rebuttal of Allegro's theory in the 1970 book "A Christian View of the Mushroom Myth"; he notes that neither fly agarics nor their host trees are found in the Middle East, even though cedars and pines are found there, and.

Amanita muscaria. highlights the tenuous nature of the links between biblical and Sumerian names coined by Allegro. He concludes that if the theory were true, the use of the mushroom must have been "the best kept secret in the world" as it was so well concealed for two thousand years.## Culinary use.The toxins in "A. muscaria" are water-soluble: parboiling "A. muscaria" fruit bodies can detoxify them and render them edible, although consumption of the mushroom as a food has never been widespread. The consumption of detoxified "A. muscaria" has been practiced in some parts of Europe (notably by Russian settlers in Siberia).

Amanita muscaria. since at least the 19th century, and likely earlier. The German physician and naturalist Georg Heinrich von Langsdorff wrote the earliest published account on how to detoxify this mushroom in 1823. In the late 19th century, the French physician Félix Archimède Pouchet was a populariser and advocate of "A. muscaria" consumption, comparing it to manioc, an important food source in tropical South America that must be detoxified before consumption.Use of this mushroom as a food source also seems to have existed in North America. A classic description of this use of "A. muscaria" by an African-American mushroom seller in Washington,.

Amanita muscaria. D.C., in the late 19th century is described by American botanist Frederick Vernon Coville. In this case, the mushroom, after parboiling, and soaking in vinegar, is made into a mushroom sauce for steak. It is also consumed as a food in parts of Japan. The most well-known current use as an edible mushroom is in Nagano Prefecture, Japan. There, it is primarily salted and pickled.A 2008 paper by food historian William Rubel and mycologist David Arora gives a history of consumption of "A. muscaria" as a food and describes detoxification methods. They advocate that "Amanita muscaria" be described in field.

Amanita muscaria. guides as an edible mushroom, though accompanied by a description on how to detoxify it. The authors state that the widespread descriptions in field guides of this mushroom as poisonous is a reflection of cultural bias, as several other popular edible species, notably morels, are toxic unless properly cooked.## Cultural depictions.The red-and-white spotted toadstool is a common image in many aspects of popular culture. Garden ornaments and children's picture books depicting gnomes and fairies, such as the Smurfs, often show fly agarics used as seats, or homes. Fly agarics have been featured in paintings since the Renaissance, albeit in a.

Amanita muscaria. subtle manner. For instance, in Hieronymus Bosch's painting, The Garden of Earthly Delights, the mushroom can be seen on the left-hand panel of the work. In the Victorian era they became more visible, becoming the main topic of some fairy paintings. Two of the most famous uses of the mushroom are in the "Mario" franchise (specifically two of the Super Mushroom power-up items and the platforms in several stages which are based on a fly agaric), and the dancing mushroom sequence in the 1940 Disney film "Fantasia".An account of the journeys of Philip von Strahlenberg to Siberia and his descriptions.

Amanita muscaria. of the use of the "mukhomor" there was published in English in 1736. The drinking of urine of those who had consumed the mushroom was commented on by Anglo-Irish writer Oliver Goldsmith in his widely read 1762 novel, "Citizen of the World". The mushroom had been identified as the fly agaric by this time. Other authors recorded the distortions of the size of perceived objects while intoxicated by the fungus, including naturalist Mordecai Cubitt Cooke in his books "The Seven Sisters of Sleep" and "A Plain and Easy Account of British Fungi". This observation is thought to have formed the.

Amanita muscaria. basis of the effects of eating the mushroom in the 1865 popular story "Alice's Adventures in Wonderland". A hallucinogenic "scarlet toadstool" from Lappland is featured as a plot element in Charles Kingsley's 1866 novel "Hereward the Wake" based on the medieval figure of the same name. Thomas Pynchon's 1973 novel "Gravity's Rainbow" describes the fungus as a "relative of the poisonous Destroying angel" and presents a detailed description of a character preparing a cookie bake mixture from harvested "Amanita muscaria". Fly agaric shamanism is also explored in the 2003 novel "Thursbitch" by Alan Garner. List of "Amanita" species Legal status.

White-tailed deer. The white-tailed deer (Odocoileus virginianus), also known as the whitetail or Virginia deer, is a medium-sized deer native to North America, Central America, and South America as far south as Peru and Bolivia. It has also been introduced to New Zealand, all the Greater Antilles in the Caribbean (Cuba, Jamaica, Hispaniola, and Puerto Rico), and some countries in Europe, such as the Czech Republic, Finland, France, Germany, Romania and Serbia.

Rye. Rye ("Secale cereale") is a grass grown extensively as a grain, a cover crop and a forage crop. It is a member of the wheat tribe (Triticeae) and is closely related to both wheat ("Triticum") and barley (genus "Hordeum"). Rye grain is used for flour, bread, beer, crispbread, some whiskeys, some vodkas, and animal fodder. It can also be eaten whole, either as boiled rye berries or by being rolled, similar to rolled oats.Rye is a cereal grain and should not be confused with ryegrass, which is used for lawns, pasture, and as hay for livestock.## History.Rye is one of.

Rye. of herbicides.Rye is a common, unwanted invader of winter wheat fields. If allowed to grow and mature, it may cause substantially reduced prices (docking) for harvested wheat.## Frost resistance."Secale cereale" can thrive in subzero environments. The leaves of winter "S. cereale" produce various antifreeze polypeptides (these are different from the antifreeze polypeptides produced by some fish and insects).## Diseases.Rye is highly susceptible to the ergot fungus. Consumption of ergot-infected rye by humans and animals results in a serious medical condition known as ergotism. Ergotism can cause both physical and mental harm, including convulsions, miscarriage, necrosis of digits, hallucinations and death.

Rye. Historically, damp northern countries that have depended on rye as a staple crop were subject to periodic epidemics of this condition. Such epidemics have been found to correlate with periods of frequent witch trials, such as the Salem witch trials in Massachusetts in 1692. Modern grain-cleaning and milling methods have practically eliminated the disease, but contaminated flour may end up in bread and other food products if the ergot is not removed before milling.## Diversity and uses.Along with "Secale cereale's" relationship and impact on the environment, it is also a valuable species because of its expansive diversity and uses.

Wolf. competition for food within the pack. Wolves are also territorial and fights over territory are among the principal causes of wolf mortality. The wolf is mainly a carnivore and feeds on large wild hooved mammals as well as smaller animals, livestock, carrion, and garbage. Single wolves or mated pairs typically have higher success rates in hunting than do large packs. Pathogens and parasites, notably rabies virus, may infect wolves.The global wild wolf population was estimated to be 300,000 in 2003 and is considered to be of Least Concern by the International Union for Conservation of Nature (IUCN). Wolves have a.

Wolf. long history of interactions with humans, having been despised and hunted in most pastoral communities because of their attacks on livestock, while conversely being respected in some agrarian and hunter-gatherer societies. The wolf is also considered the ancestor of the domestic dog. Although the fear of wolves exists in many human societies, the majority of recorded attacks on people have been attributed to animals suffering from rabies. Wolf attacks on humans are rare because wolves are relatively few, live away from people, and have developed a fear of humans because of their experiences with hunters, ranchers, and shepherds.## Etymology.The English.

Wolf. and Wolfdregil ("Wolf Runner").## Taxonomy.In 1758, the Swedish botanist and zoologist Carl Linnaeus published in his "Systema Naturae" the binomial nomenclature. "Canis" is the Latin word meaning "dog", and under this genus he listed the doglike carnivores including domestic dogs, wolves, and jackals. He classified the domestic dog as "Canis familiaris", and the wolf as "Canis lupus". Linnaeus considered the dog to be a separate species from the wolf because of its "cauda recurvata" (upturning tail) which is not found in any other canid.## Subspecies.In the third edition of "Mammal Species of the World" published in 2005, the mammalogist W.

Wolf. Christopher Wozencraft listed under "C. lupus" 36 wild subspecies, and proposed two additional subspecies: "familiaris" (Linnaeus, 1758) and "dingo" (Meyer, 1793). Wozencraft included "hallstromi"—the New Guinea singing dog—as a taxonomic synonym for the dingo. Wozencraft referred to a 1999 mitochondrial DNA (mtDNA) study as one of the guides in forming his decision, and listed the 38 subspecies of "C. lupus" under the biological common name of "wolf", the nominate subspecies being the Eurasian wolf ("C. l. lupus") based on the type specimen that Linnaeus studied in Sweden. Studies using paleogenomic techniques reveal that the modern wolf and the dog are.

Wolf. sister taxa, as modern wolves are not closely related to the population of wolves that was first domesticated. In 2019, a workshop hosted by the IUCN/Species Survival Commission's Canid Specialist Group considered the New Guinea singing dog and the dingo to be feral "Canis familiaris", and therefore should not be assessed for the IUCN Red List.## Evolution.The phylogenetic descent of the extant wolf "C. lupus" from "C. etruscus" through "C. mosbachensis" is widely accepted. The earliest fossils of "C. lupus" were found in what was once eastern Beringia at Old Crow, Yukon, Canada, and at Cripple Creek Sump, Fairbanks, Alaska.

Wolf. often processed carcasses, or that they competed with other carnivores and needed to consume their prey quickly. Compared with those found in the modern spotted hyena, the frequency and location of tooth fractures in these wolves indicates they were habitual bone crackers.Genomic studies suggest modern wolves and dogs descend from a common ancestral wolf population that existed 20,000 years ago. A 2021 study found that the Himalayan wolf and the Indian plains wolf are part of a lineage that is basal to other wolves and split from them 200,000 years ago. Other wolves appear to have originated in Beringia in.

Wolf. an expansion that was driven by the huge ecological changes during the close of the Late Pleistocene. A study in 2016 indicates that a population bottleneck was followed by a rapid radiation from an ancestral population at a time during, or just after, the Last Glacial Maximum. This implies the original morphologically diverse wolf populations were out-competed and replaced by more modern wolves.A 2016 genomic study suggests that Old World and New World wolves split around 12,500 years ago followed by the divergence of the lineage that led to dogs from other Old World wolves around 11,100–12,300 years ago. An.

Wolf. extinct Late Pleistocene wolf may have been the ancestor of the dog, with the dog's similarity to the extant wolf being the result of genetic admixture between the two. The dingo, Basenji, Tibetan Mastiff and Chinese indigenous breeds are basal members of the domestic dog clade. The divergence time for wolves in Europe, the Middle East, and Asia is estimated to be fairly recent at around 1,600 years ago. Among New World wolves, the Mexican wolf diverged around 5,400 years ago.## Admixture with other canids.In the distant past, there has been gene flow between African wolves, golden jackals, and gray.

Wolf. wolves. The African wolf is a descendant of a genetically admixed canid of 72% wolf and 28% Ethiopian wolf ancestry. One African wolf from the Egyptian Sinai Peninsula shows admixture with Middle Eastern gray wolves and dogs. There is evidence of gene flow between golden jackals and Middle Eastern wolves, less so with European and Asian wolves, and least with North American wolves. This indicates the golden jackal ancestry found in North American wolves may have occurred before the divergence of the Eurasian and North American wolves.The common ancestor of the coyote and the wolf has admixed with a ghost.

Wolf. population of an extinct unidentified canid. This canid is genetically close to the dhole and evolved after the divergence of the African hunting dog from the other canid species. The basal position of the coyote compared to the wolf is proposed to be due to the coyote retaining more of the mitochondrial genome of this unidentified canid. Similarly, a museum specimen of a wolf from southern China collected in 1963 showed a genome that was 12–14% admixed from this unknown canid. In North America, most coyotes and wolves show varying degrees of past genetic admixture. The red wolf of the.

Wolf. southeastern United States is a hybrid animal with 40%:60% wolf to coyote ancestry. In addition, there was found to be 60%:40% wolf to coyote genetics in Eastern timber wolves, and 75%:25% in the Great Lakes region wolves.In more recent times, some male Italian wolves originated from dog ancestry, which indicates female wolves will breed with male dogs in the wild. In the Caucasus Mountains, ten percent of dogs including livestock guardian dogs, are first generation hybrids. Although mating between golden jackals and wolves has never been observed, evidence of jackal-wolf hybridization was discovered through mitochondrial DNA analysis of jackals living.

Wolf. in the Caucasus Mountains and in Bulgaria.In 2021, a genetic study found that the dog's similarity to the extant gray wolf was the result of substantial dog-into-wolf gene flow, with almost negligible wolf-into-dog gene flow since the dog's domestication. Some gray wolves were related to all ancient and modern dogs.## Description.The wolf is the largest extant member of the Canidae family, and is further distinguished from coyotes and jackals by a broader snout, shorter ears, a shorter torso and a longer tail. It is slender and powerfully built, with a large, deeply descending rib cage, a sloping back, and a.

Wolf. the calcaneal tendons. The winter fur is highly resistant to the cold. Wolves in northern climates can rest comfortably in open areas at -40 (C) by placing their muzzles between the rear legs and covering their faces with their tail. Wolf fur provides better insulation than dog fur and does not collect ice when warm breath is condensed against it.In cold climates, the wolf can reduce the flow of blood near its skin to conserve body heat. The warmth of the foot pads is regulated independently from the rest of the body and is maintained at just above tissue-freezing point.

Wolf. southern Canada, the U.S., and Mexico being predominantly gray. In some areas of the Rocky Mountains of Alberta and British Columbia, the coat colour is predominantly black, some being blue-gray and some with silver and black. Differences in coat colour between sexes is absent in Eurasia; females tend to have redder tones in North America. Black-coloured wolves in North America acquired their colour from wolf-dog admixture after the first arrival of dogs across the Bering Strait 12,000 to 14,000 years ago. Research into the inheritance of white colour from dogs into wolves has yet to be undertaken.## Ecology.## Distribution and.

Wolf. habitat.Wolves occur across Eurasia and North America. However, deliberate human persecution because of livestock predation and fear of attacks on humans has reduced the wolf's range to about one-third of its historic range; the wolf is now extirpated (locally extinct) from much of its range in Western Europe, the United States and Mexico, and completely in Ireland, the United Kingdom, and Japan. In modern times, the wolf occurs mostly in wilderness and remote areas. The wolf can be found between sea level and 3000 (m). Wolves live in forests, inland wetlands, shrublands, grasslands (including Arctic tundra), pastures, deserts, and rocky.

Wolf. in diet between wolves living on different continents is based on the variety of hoofed mammals and of available smaller and domesticated prey.In North America, the wolf's diet is dominated by wild large hoofed mammals (ungulates) and medium-sized mammals. In Asia and Europe, their diet is dominated by wild medium-sized hoofed mammals and domestic species. The wolf depends on wild species, and if these are not readily available, as in Asia, the wolf is more reliant on domestic species. Across Eurasia, wolves prey mostly on moose, red deer, roe deer and wild boar. In North America, important range-wide prey are.

Wolf. elk, moose, caribou, white-tailed deer and mule deer. They also prey on bison and muskoxen. Wolves can digest their meal in a few hours and can feed several times in one day, making quick use of large quantities of meat. A well-fed wolf stores fat under the skin, around the heart, intestines, kidneys, and bone marrow, particularly during the autumn and winter.Nonetheless, wolves are not fussy eaters. Smaller-sized animals that may supplement their diet include rodents, rabbits, hares, insectivores and smaller carnivores. They frequently eat waterfowl and their eggs. When such foods are insufficient, they prey on lizards, snakes, frogs,.

Wolf. and large insects when available. Wolves in northern Minnesota prey on northern pike in freshwater streams. The diet of coastal wolves in Alaska includes 20% salmon, while those of coastal wolves in British Columbia includes 25% marine sources, and those on the nearby islands 75%.In Europe, wolves eat apples, pears, figs, melons, berries and cherries. In North America, wolves eat blueberries and raspberries. Wolves also eat grass, which may provide some vitamins, but is most likely used mainly to induce vomiting to rid themselves of intestinal parasites or long guard hairs. They are known to eat the berries of mountain-ash,.

Wolf. lily of the valley, bilberries, cowberries, European black nightshade, grain crops, and the shoots of reeds.In times of scarcity, wolves will readily eat carrion. In Eurasian areas with dense human activity, many wolf populations are forced to subsist largely on livestock and garbage. Prey in North America continue to occupy suitable habitats with low human density, the wolves eating livestock and garbage only in dire circumstances. Cannibalism is not uncommon in wolves during harsh winters, when packs often attack weak or injured wolves and may eat the bodies of dead pack members.## Interactions with other predators.Wolves typically dominate other canid.

Wolf. adjacent mountain ranges. Wolves and cougars typically avoid encountering each other by hunting at different elevations for different prey (niche partitioning). In winter, when snow accumulation forces their prey into valleys, interactions between the two species become more likely. Wolves in packs usually dominate cougars and can steal their kills or even kill them, while one-to-one encounters tend to be dominated by the cat. There are several documented cases of cougars killing wolves. Wolves more broadly affect cougar population dynamics and distribution by dominating territory and prey opportunities and disrupting the feline's behaviour. Wolf and Siberian tiger interactions are well-documented.

Wolf. off single or outnumbered hyenas. There is at least one case in Israel of a hyena associating and cooperating with a wolf pack. It is proposed that the hyena could benefit from the wolves' superior ability to hunt large, agile prey. The wolves could benefit from the hyena's superior sense of smell, to locate and dig out tortoises, to crack open large bones, and to tear open discarded food containers like tin cans.## Behaviour.## Social structure.The wolf is a social animal. Its populations consist of packs and lone wolves, most lone wolves being temporarily alone while they disperse from packs.

Wolf. to form their own or join another one. The wolf's basic social unit is the nuclear family consisting of a mated pair accompanied by their offspring. The average pack size in North America is eight wolves and in Europe 5.5 wolves. The average pack across Eurasia consists of a family of eight wolves (two adults, juveniles, and yearlings), or sometimes two or three such families, with examples of exceptionally large packs consisting of up to 42 wolves being known. Cortisol levels in wolves rise significantly when a pack member dies, indicating the presence of stress. During times of prey abundance.

Wolf. and the Denali National Park and Preserve were due to other wolves.## Communication.Wolves communicate using vocalizations, body postures, scent, touch, and taste. The phases of the moon have no effect on wolf vocalization, and despite popular belief, wolves do not howl at the moon. Wolves howl to assemble the pack usually before and after hunts, to pass on an alarm particularly at a den site, to locate each other during a storm, while crossing unfamiliar territory, and to communicate across great distances. Wolf howls can under certain conditions be heard over areas of up to 130 (km2). Other vocalizations include.

Wolf. growls, barks and whines. Wolves do not bark as loudly or continuously as dogs do in confrontations, rather barking a few times and then retreating from a perceived danger. Aggressive or self-assertive wolves are characterized by their slow and deliberate movements, high body posture and raised hackles, while submissive ones carry their bodies low, flatten their fur, and lower their ears and tail.Scent marking involves urine, feces, and anal gland scents. This is more effective at advertising territory than howling and is often used in combination with scratch marks. Wolves increase their rate of scent marking when they encounter the.

Wolf. marks of wolves from other packs. Lone wolves will rarely mark, but newly bonded pairs will scent mark the most. These marks are generally left every 240 (m) throughout the territory on regular travelways and junctions. Such markers can last for two to three weeks, and are typically placed near rocks, boulders, trees, or the skeletons of large animals. Raised leg urination is considered to be one of the most important forms of scent communication in the wolf, making up 60–80% of all scent marks observed.## Reproduction.Wolves are monogamous, mated pairs usually remaining together for life. Should one of the.

Wolf. better warmed by sunlight exposure, and the snow can thaw more quickly. Resting places, play areas for the pups, and food remains are commonly found around wolf dens. The odor of urine and rotting food emanating from the denning area often attracts scavenging birds like magpies and ravens. Though they mostly avoid areas within human sight, wolves have been known to nest near domiciles, paved roads and railways. During pregnancy, female wolves remain in a den located away from the peripheral zone of their territories, where violent encounters with other packs are less likely to occur.The gestation period lasts 62–75.

Wolf. blood loss, thereby lessening the risk of injury to themselves. With medium-sized prey, such as roe deer or sheep, wolves kill by biting the throat, severing nerve tracks and the carotid artery, thus causing the animal to die within a few seconds to a minute. With small, mouselike prey, wolves leap in a high arc and immobilize it with their forepaws.Once prey is brought down, wolves begin to feed excitedly, ripping and tugging at the carcass in all directions, and bolting down large chunks of it. The breeding pair typically monopolizes food to continue producing pups. When food is scarce,.

Wolf. wolf attacks on people being attributed to rabid animals. Although canine distemper is lethal in dogs, it has not been recorded to kill wolves, except in Canada and Alaska. The canine parvovirus, which causes death by dehydration, electrolyte imbalance, and endotoxic shock or sepsis, is largely survivable in wolves, but can be lethal to pups. Wolves may catch infectious canine hepatitis from dogs, though there are no records of wolves dying from it. Papillomatosis has been recorded only once in wolves, and likely does not cause serious illness or death, though it may alter feeding behaviours. The canine coronavirus has.

Wolf. been recorded in Alaskan wolves, infections being most prevalent in winter months.Bacterial diseases carried by wolves include: brucellosis, Lyme disease, leptospirosis, tularemia, bovine tuberculosis, listeriosis and anthrax. Wolves can catch "Brucella suis" from wild and domestic reindeer. While adult wolves tend not to show any clinical signs, it can severely weaken the pups of infected females. Although lyme disease can debilitate individual wolves, it does not appear to significantly affect wolf populations. Leptospirosis can be contracted through contact with infected prey or urine, and can cause fever, anorexia, vomiting, anemia, hematuria, icterus, and death. Wolves living near farms are more.

Wolf. vulnerable to the disease than those living in the wilderness, probably because of prolonged contact with infected domestic animal waste. Wolves may catch tularemia from lagomorph prey, though its effect on wolves is unknown. Although bovine tuberculosis is not considered a major threat to wolves, it has been recorded to have killed two wolf pups in Canada.## Parasitic.Wolves carry ectoparasites and endoparasites; those in the former Soviet Union have been recorded to carry at least 50 species. Most of these parasites infect wolves without adverse effects, though the effects may become more serious in sick or malnourished specimens. Parasitic infection.

Wolf. in wolves is of particular concern to people. Wolves can spread them to dogs, which in turn can carry the parasites to humans. In areas where wolves inhabit pastoral areas, the parasites can be spread to livestock.Wolves are often infested with a variety of arthropod exoparasites, including fleas, ticks, lice, and mites. The most harmful to wolves, particularly pups, is the mange mite ("Sarcoptes scabiei"), though they rarely develop full-blown mange, unlike foxes. Lice, such as "Trichodectes canis", may cause sickness in wolves, but rarely death. Ticks of the genus "Ixodes" can infect wolves with Lyme disease and Rocky Mountain.

Wolf. spotted fever. The tick "Dermacentor pictus" also infests wolves. Other ectoparasites include chewing lice, sucking lice and the fleas "Pulex irritans" and "Ctenocephalides canis".Endoparasites known to infect wolves include: protozoans and helminths (flukes, tapeworms, roundworms and thorny-headed worms). Of 30,000 protozoan species, only a few have been recorded to infect wolves: "Isospora", "Toxoplasma", "Sarcocystis", "Babesia", and "Giardia". Some wolves carry "Neospora caninum", which can be spread to cattle and is correlated with bovine miscarriages. Among flukes, the most common in North American wolves is "Alaria", which infects small rodents and amphibians which are eaten by wolves. Upon reaching maturity, "Alaria.

Wolf. migrates to the wolf's intestine, but does little harm. "Metorchis conjunctus", which enters wolves through eating fish, infects the wolf's liver or gall bladder, causing liver disease, inflammation of the pancreas, and emaciation. Most other fluke species reside in the wolf's intestine, though "Paragonimus westermani" lives in the lungs. Tapeworms are commonly found in wolves, as their primary hosts are ungulates, small mammals, and fish, which wolves feed upon. Tapeworms generally cause little harm in wolves, though this depends on the number and size of the parasites, and the sensitivity of the host. Symptoms often include constipation, toxic and allergic.

Wolf. intestinal irritation, bloating, vomiting, and diarrhea. Wolves may catch "Dioctophyma renale" from minks, which infects the kidneys, and can grow to lengths of 100 (cm). "D. renale" causes the complete destruction of the kidney's functional tissue and can be fatal if both kidneys are infected. Wolves can tolerate low levels of "Dirofilaria immitis" for many years without showing any ill effects, though high levels can kill wolves through cardiac enlargement and congestive hepatopathy. Wolves probably become infected with "Trichinella spiralis" by eating infected ungulates. Although "T. spiralis" is not known to produce clinical signs in wolves, it can cause emaciation,.

Wolf. salivation, and crippling muscle pains in dogs. Thorny-headed worms rarely infect wolves, though three species have been identified in Russian wolves: "Nicolla skrjabini", "Macracanthorhynchus catulinus", and "Moniliformis moniliformis".## Status and conservation.The global wild wolf population in 2003 was estimated at 300,000. Wolf population declines have been arrested since the 1970s. This has fostered recolonization and reintroduction in parts of its former range as a result of legal protection, changes in land use, and rural human population shifts to cities. Competition with humans for livestock and game species, concerns over the danger posed by wolves to people, and habitat fragmentation pose.

Wolf. world. His most famous is the fable of "The Boy Who Cried Wolf", which is directed at those who knowingly raise false alarms, and from which the idiomatic phrase "to cry wolf" is derived. Some of his other fables concentrate on maintaining the trust between shepherds and guard dogs in their vigilance against wolves, as well as anxieties over the close relationship between wolves and dogs. Although Aesop used wolves to warn, criticize and moralize about human behaviour, his portrayals added to the wolf's image as a deceitful and dangerous animal. The Bible uses an image of a wolf lying.

Wolf. Ivan Bunin, Leonid Pavlovich Sabaneyev, and others. Tolstoy's "War and Peace" and Chekhov's "Peasants" both feature scenes in which wolves are hunted with hounds and Borzois. The musical "Peter and the Wolf" involves a wolf being captured for eating a duck, but is spared and sent to a zoo.Wolves are among the central characters of Rudyard Kipling's "The Jungle Book". His portrayal of wolves has been praised posthumously by wolf biologists for his depiction of them: rather than being villainous or gluttonous, as was common in wolf portrayals at the time of the book's publication, they are shown as living.

Wolf. in amiable family groups and drawing on the experience of infirm but experienced elder pack members. Farley Mowat's largely fictional 1963 memoir "Never Cry Wolf" is widely considered to be the most popular book on wolves, having been adapted into a Hollywood film and taught in several schools decades after its publication. Although credited with having changed popular perceptions on wolves by portraying them as loving, cooperative and noble, it has been criticized for its idealization of wolves and its factual inaccuracies.## Conflicts.Human presence appears to stress wolves, as seen by increased cortisol levels in instances such as snowmobiling near.

Wolf. their territory.## Predation on livestock.Livestock depredation has been one of the primary reasons for hunting wolves and can pose a severe problem for wolf conservation. As well as causing economic losses, the threat of wolf predation causes great stress on livestock producers, and no foolproof solution of preventing such attacks short of exterminating wolves has been found. Some nations help offset economic losses to wolves through compensation programs or state insurance. Domesticated animals are easy prey for wolves, as they have been bred under constant human protection, and are thus unable to defend themselves very well. Wolves typically resort to.

Wolf. attacking livestock when wild prey is depleted. In Eurasia, a large part of the diet of some wolf populations consists of livestock, while such incidents are rare in North America, where healthy populations of wild prey have been largely restored.The majority of losses occur during the summer grazing period, untended livestock in remote pastures being the most vulnerable to wolf predation. The most frequently targeted livestock species are sheep (Europe), domestic reindeer (northern Scandinavia), goats (India), horses (Mongolia), cattle and turkeys (North America). The number of animals killed in single attacks varies according to species: most attacks on cattle and.

Wolf. horses result in one death, while turkeys, sheep and domestic reindeer may be killed in surplus. Wolves mainly attack livestock when the animals are grazing, though they occasionally break into fenced enclosures.## Competition with dogs.A review of the studies on the competitive effects of dogs on sympatric carnivores did not mention any research on competition between dogs and wolves. Competition would favour the wolf, which is known to kill dogs; however, wolves usually live in pairs or in small packs in areas with high human persecution, giving them a disadvantage when facing large groups of dogs.Wolves kill dogs on occasion,.

Wolf. and some wolf populations rely on dogs as an important food source. In Croatia, wolves kill more dogs than sheep, and wolves in Russia appear to limit stray dog populations. Wolves may display unusually bold behaviour when attacking dogs accompanied by people, sometimes ignoring nearby humans. Wolf attacks on dogs may occur both in house yards and in forests. Wolf attacks on hunting dogs are considered a major problem in Scandinavia and Wisconsin. The most frequently killed hunting breeds in Scandinavia are Harriers, older animals being most at risk, likely because they are less timid than younger animals, and react.

Wolf. to the presence of wolves differently. Large hunting dogs such as Swedish Elkhounds are more likely to survive wolf attacks because of their better ability to defend themselves.Although the number of dogs killed each year by wolves is relatively low, it induces a fear of wolves entering villages and farmyards to prey on them. In many cultures, dogs are seen as family members, or at least working team members, and losing one can lead to strong emotional responses such as demanding more liberal hunting regulations.Dogs that are employed to guard sheep help to mitigate human–wolf conflicts, and are often proposed.

Wolf. as one of the non-lethal tools in the conservation of wolves. Shepherd dogs are not particularly aggressive, but they can disrupt potential wolf predation by displaying what is to the wolf ambiguous behaviours, such as barking, social greeting, invitation to play or aggression. The historical use of shepherd dogs across Eurasia has been effective against wolf predation, especially when confining sheep in the presence of several livestock guardian dogs. Shepherd dogs are sometimes killed by wolves.## Attacks on humans.The fear of wolves has been pervasive in many societies, though humans are not part of the wolf's natural prey. How wolves.

Wolf. almost always women. Indian wolves have a history of preying on children, a phenomenon called "child-lifting". They may be taken primarily in the spring and summer periods during the evening hours, and often within human settlements.Cases of rabid wolves are low when compared to other species, as wolves do not serve as primary reservoirs of the disease, but can be infected by animals such as dogs, jackals and foxes. Incidents of rabies in wolves are very rare in North America, though numerous in the eastern Mediterranean, the Middle East and Central Asia. Wolves apparently develop the "furious" phase of rabies.

Wolf. to a very high degree. This, coupled with their size and strength, makes rabid wolves perhaps the most dangerous of rabid animals. Bites from rabid wolves are 15 times more dangerous than those of rabid dogs. Rabid wolves usually act alone, travelling large distances and often biting large numbers of people and domestic animals. Most rabid wolf attacks occur in the spring and autumn periods. Unlike with predatory attacks, the victims of rabid wolves are not eaten, and the attacks generally occur only on a single day. The victims are chosen at random, though most cases involve adult men. During.

Wolf. the fifty years up to 2002, there were eight fatal attacks in Europe and Russia, and more than two hundred in southern Asia.## Human hunting of wolves.Theodore Roosevelt said wolves are difficult to hunt because of their elusiveness, sharp senses, high endurance, and ability to quickly incapacitate and kill a dog. Historic methods included killing of spring-born litters in their dens, coursing with dogs (usually combinations of sighthounds, Bloodhounds and Fox Terriers), poisoning with strychnine, and trapping.A popular method of wolf hunting in Russia involves trapping a pack within a small area by encircling it with fladry poles carrying a.

Wolf. human scent. This method relies heavily on the wolf's fear of human scents, though it can lose its effectiveness when wolves become accustomed to the odor. Some hunters can lure wolves by imitating their calls. In Kazakhstan and Mongolia, wolves are traditionally hunted with eagles and falcons, though this practice is declining, as experienced falconers are becoming few in number. Shooting wolves from aircraft is highly effective, due to increased visibility and direct lines of fire. Several types of dog, including the Borzoi and Kyrgyz Tajgan, have been specifically bred for wolf hunting.## As pets and working animals.Wolves and wolf-dog.

Wolf. hybrids are sometimes kept as exotic pets. Although closely related to domestic dogs, wolves do not show the same tractability as dogs in living alongside humans, being generally less responsive to human commands and more likely to act aggressively. A person is more likely to be fatally mauled by a pet wolf or wolf-dog hybrid than by a dog.The International Wolf CenterStaying Safe in Wolf Country, ADFG (January 2009)Watch "Death of a Legend" and "Cry of the Wild" by Bill Mason.


Question: What is the closest upper taxonomy of this plant?

Instruction: I want to find a paragraph from Wikipedia that answers my question about this image.

Dacrycarpus dacrydioides. Dacrycarpus dacrydioides, commonly known as kahikatea (from Māori) and white pine, is a coniferous tree endemic to New Zealand. A podocarp, it is New Zealand's tallest tree, gaining heights of 60 m and a life span of 600 years. It was first described botanically by the French botanist Achille Richard in 1832 as "Podocarpus" "dacrydioides", and was given its current binomial name "Dacrycarpus dacrydioides" in 1969 by the American botanist David de Laubenfels. Analysis of DNA has confirmed its evolutionary relationship with other species in the genera "Dacrycarpus" and "Dacrydium".In traditional Māori culture, it is an important source of timber.

Dacrycarpus dacrydioides. for the building of waka and making of tools, of food in the form of its berries, and of dye. When Europeans discovered it in the 18th century they found large remnant stands in both the North and South Islands, despite burning of forest by early Māori. Its use for timber and its damp fertile habitat, ideal for dairy farming, have led to its decimation almost everywhere except South Westland.Kahikatea seeds have fleshy structures called receptacles attached to them, which encourage birds such as kererū and tūī to eat them and disperse the seeds. The water storage ability of this.

Dacrycarpus dacrydioides. structures may also be to protect seeds from drying out. It supports many smaller plants in its own branches, which are called epiphytes; 100 different species have been recorded on one tree alone.## Description.The kahikatea is a coniferous tree reaching a height of 50–65 (m), making it the tallest New Zealand tree, with a trunk 1–2 (m) through. It has a 600 year life span and gains maturity after between 250 and 450 years. Near the base of the tree, the roots are typically buttressed and grooved. The wood itself is odourless and white. The majority of the trunk is.

Dacrycarpus dacrydioides. branchless—in adults around three quarters—and has grey or dark grey coloured bark which falls off thickly in flakes. Young adults have no branches in a third to a half of the trunk and have a conic shape.In juveniles the leaves are 3–7 (reaching 4 mm in young adults) by 0.5–1 mm and a dark green to red colour that come to a marked point. They are narrow, arranged in almost opposite pairs spreading away from a wider base, and curved like a scythe. In adulthood the leaves change dramatically and are a brown-green colour and just 1–2 mm long, waxy,.

Dacrycarpus dacrydioides. and grow overlapping one another tightly.As a conifer, the kahikatea has no flowers and instead has cones. Male cones, which occur on different trees to female ones, are 1 cm long and rectangular. The pollen is a pale yellow colour and has a three-pored or trisaccate shape that is distinctive in the New Zealand flora and so can be identified easily. The fruit is highly modified with a yellow-orange fleshy receptacle that is 2.5–6.5 mm long. The purple-black seed is roughly spherical and 4–6 mm in diameter. Both the seed and the ovary are covered with a thin layer of.

Dacrycarpus dacrydioides. wax. The kahikatea has a diploid chromosome count of 20.## Phytochemistry.Several different glycosides have been isolated from the leaves; the tricetin 3’,5’-di-O-/β-glucopyranoside and 3’-0-β-xylopyranoside have been found only in the kahikatea. The receptacles and seeds have been found to contain anthocyanins, rare in gymnosperms, which it was suggested in one 1988 paper make the fruit as a whole more attractive to prospective animal dispersers.## Taxonomy.The kahikatea was first described in 1832 by the French botanist Achille Richard in his "Essai d'une Flore de la Nouvelle Zélande" (Essay On The Flora of New Zealand) as "Podocarpus" "dacrydioides". There is an earlier.

Dacrycarpus dacrydioides. record given in the 1825 issue of "Mémoires du Muséum d'histoire naturelle" as "Podocarpus thujoides", but it lacks a description. It was superfluously named "Dacrydium excelsum" by Allan Cunningham in the 1838 issue of Annals of Natural History, and transferred to the genus "Nageia" by Otto Kuntze in 1891. It was given its current binomial name, "Dacrycarpus dacrydioides," in 1969 by American botanist David de Laubenfels.## Etymology."Dacrycarpus" means tear shaped fruit, and the specific epithet "dacrydioides" is after its similarity to species in the genus "Dacrydium". Common names include kahikatea, from the Māori language, and white pine. Other Māori names.

Dacrycarpus dacrydioides. recorded by 19th century ethnographers include: katea, kaikatea, koroī, kōaka, kahika, and the name kāī (for the young tree).## Evolution.A 2022 study in "Molecular Phylogenetics and Evolution", found a phylogeny, or evolutionary tree, in which kahikatea is found to be within a "Darcydioid" clade. This group of species that share a common ancestor also gave rise to the other "Dacrycarpus" species as well as those in the genus "Darcydium". They suggested it diverged from a common ancestor around 60 million years ago, in the early paleogene. This is represented in the cladogram below.## Distribution and habitat.The kahikatea is endemic to.

Dacrycarpus dacrydioides. the North, South, and Stewart Islands of New Zealand. It inhabits mostly lowland forests between 0 and 600m above sea level, though may in rare cases reach montane areas. It used to dominate a swamp forest type that now exists almost only on the South Westland region of the South Island. Kahikatea prefers flooded or alluvial soils with low levels of drainage, which in Westland occur from post glaciation events.## Ecology.## Dispersal.Under optimal circumstances a mature kahikatea can produce 800 (kg) of fruit, equivalent to 4.5 million seeds, in a year. The fruit contains a special fleshy structure called a.

Dacrycarpus dacrydioides. receptacle which helps attract birds such as the kererū, tūī, and bellbird, who then eat the fruit and disperse the seed elsewhere. One 2008 study in the New Zealand Journal of Ecology found a mean retention time of kahikatea seeds in kererū of 44.5 minutes. It was suggested in a 1989 study that the high water content of the receptacle may also help protect the seeds, which are vulnerable to drying out, from dry conditions. It may also serve as a storage vessel for water. The bluish seeds have very strong UV reflectance, which is visible to some species of.

Dacrycarpus dacrydioides. birds.## Epiphytes.Kahikatea can support a vast number of non-parasitic plants that live in its branches, called epiphytes. One 2002 study identified between 90 and 100 species occurring on one mature tree. This included 49 vascular plants and over 50 non-vascular plants, which the authors identified as comparable to the number found on a "Prumnopitys exigua" in Bolivian cloud forest.## Competition.Intraspecific competition between kahikatea trees was found in a 1999 study to be an important factor in their survival and overall success, affecting both growth rates and rates of mortality. Older trees have a particularly large advantage over resources compared to.

Dacrycarpus dacrydioides. newer ones, and also have higher growth rates. Following flooding or other natural events, the kahikatea has been found to require an open canopy in order to re-establish. Because of the consistency of these events in South Westland however, many forested areas don't progress beyond regaining kahikatea and rimu, as other species, such as kāmahi, need the environment to improve before they can return.## Conservation.Prior to the arrival of humans in New Zealand around 75% of the country was covered in trees, and kahikatea dominated its own and once widespread kahikatea forest type. Even after the burning of many forests.

Dacrycarpus dacrydioides. by early Māori, there still remained large remnant forests which European settlers came upon in the 18th and 19th centuries. Prospects for use as timber were accelerated by the vast numbers of straight and tall trees, but because the wood is soft and odourless, it was made into pulp, barrels and boxes–butter boxes in particular were made mostly out of kahikatea. The kahikatea's usually flat habitat, with its damp and fertile soil, was also a prime location for dairy farming. Together this led to the felling of much of the remaining forests in the North and South Islands during the.

Dacrycarpus dacrydioides. late 19th and early 20th centuries. Today they are confined mostly to the South Westland region of the South Island, though small remnants still exist in some places.Conservation efforts have focused on protecting and fencing kahikatea forests around the country. Riccarton Bush is one notable example of forest remnant protection. The near 16 (acre) reserve was held in the Deans family for 70 years before it was gifted to Christchurch by them in 1914, and subsequently formally protected in the Riccarton Bush Bill. It is the only surviving kahikatea forest remnant in the entire Canterbury Plains, and contains trees up.

Dacrycarpus dacrydioides. to 600 years old. Reservation of stands may not totally protect kahikatea, however, because the alluvial plains that they favour are prone to upheaval and erosion and so trees may still become damaged. Forest remnants outside of South Westland face the threat of never returning to their natural states, as a result of their small size, threats from weed species, and grazing by livestock. Despite this, the kahikatea has been classified as Least concern by the International Union for Conservation of Nature and "Not Threatened" by the New Zealand Threat Classification System, which gives it an estimated population of above.

Dacrycarpus dacrydioides. 100,000.## In Māori culture.In Māori mythology the kahikatea is a child of Tāne, the god of forests and birds, and Hine-wao-riki. It served as an important source of wood for the making of tools, of dye, and of food from its berries. To collect the latter, Māori had to climb sometimes more than 100 (ft) to reach them.19th century British ethnographers Richard Taylor, Eldson Best, and William Colenso all recorded the fruit of kahikatea being eaten, and that it was given its own name: koroī. Best described berries being collected in a basket and then hoisted down using a cord.

Dacrycarpus dacrydioides. J. H. Kerry-Nicholls and William Colenso both recorded a blue or black dye being obtained from the soot of burning the kahikatea's resin or heart wood, called kāpara or māpara. This was described as then being used in tattooing. This resin was also used as chewing gum.The wood could be made into canoes, called waka, but Best recorded that because of the softness of the wood they were far inferior to those made from tōtara. The heartwood was far stronger and R. H. Matthews described it as being used in tools and weapons such as spears. Medicinal applications were described.
