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.

Cerioporus squamosus. Cerioporus squamosus aka "Polyporus squamosus" is a basidiomycete bracket fungus, with common names including dryad's saddle and pheasant's back mushroom. It has a widespread distribution, being found in North America, Australia, Asia, and Europe, where it causes a white rot in the heartwood of living and dead hardwood trees. The name "dryad's saddle" refers to creatures in Greek mythology called dryads who could conceivably fit and ride on this mushroom, whereas the "pheasant's back" analogy derives from the pattern of colors on the bracket matching that of a pheasant's back.## Etymology."Squamosus" comes from the Latin "squamosus" meaning covered with scales.

Cerioporus squamosus. or scaly, referring to the signature dark brown scales found on the mushroom's cap.## Taxonomy.The species was first described scientifically by British botanist William Hudson in 1778, who named it "Boletus squamosus". It was given its current name in 1886 by Quélet but is still widely known by the Friesian name "Polyporus squamosus".## Description.Dryad's Saddle is an annual mushroom commonly found attached to dead logs and stumps or on living hardwood trees at one point with a thick stem. Generally, the fruit body is round and between 8 – 30 (cm) across and up to 10 (cm) thick. The body.

Cerioporus squamosus. can be yellow to brown and has "squamules" or scales on its upper side. On the underside one can see the pores that are characteristic of the genus "Cerioporus"; they are made up of tubes packed together closely. The tubes are between 1 and 12 (mm) long. The stalk is thick and short, up to 5 (cm) long. The fruit body will produce a white spore print if laid onto a sheet of paper. The spores are 11-15 x 4-5 µm and are long and smooth ellipsoids. They can be found alone, in clusters of two or three, or forming.

Cerioporus squamosus. made from this and many other mushrooms of the genus "Cerioporus". The mushroom's smell resembles watermelon rind. "Polyporus squamosus" has a mild nutty flavour.

Acacia melanoxylon. Acacia melanoxylon, commonly known as the Australian blackwood, is an "Acacia" species native in South eastern Australia. The species is also known as Blackwood, hickory, mudgerabah, Tasmanian blackwood, or blackwood acacia. The tree belongs to the "Plurinerves" section of "Acacia" and is one of the most wide-ranging tree species in eastern Australia and is quite variable mostly in the size and shape of the phyllodes.## Description.The tree is able to grow to a height of around 20 (m) and has a bole that is approximately 150 (cm) in diameter. It has deeply fissured, dark-grey to black coloured bark that appears.

Acacia melanoxylon. quite scaly on older trees. It has angular and ribbed branches The bark on older trunks is dark greyish-black in colour, deeply fissured and somewhat scaly. Younger branches are glabrous, ribbed and angular to flattened near the greenish coloured tips. The stems of younger plants are occasionally hairy. Like most species of "Acacia" it has phyllodes rather than true leaves.

Bodrum Castle. Bodrum Castle () is a historical fortification located in southwest Turkey in the port city of Bodrum (), built from 1402 onwards, by the Knights of St John as the Castle of St. Peter or "Petronium". A transnational effort, it has four towers known as the English, French, German, and Italian towers, bearing the names of the nations responsible for their construction. The castle was completed in the late 15th century, only to be taken over by the Islamic Ottoman Empire in 1523. The chapel was converted to a mosque, and a minaret was added. The castle remained under the.

Bodrum Castle. empire for almost 400 years. After remaining empty following World War I, in the early 1960s, the castle became the home for the award-winning Bodrum Museum of Underwater Archaeology (see below). In 2016 it was inscribed in the Tentative list of World Heritage Sites in Turkey.## History.Confronted by the now firmly established Ottoman Sultanate, the Knights Hospitaller, whose headquarters were on the island of Rhodes, needed another stronghold on the mainland. Grand Master Philibert de Naillac (1396–1421) identified a suitable site across from the island of Kos, where a castle had already been built by the Order. Its location was.

Bodrum Castle. the site of a fortification in Doric times (1110 BC) as well as of a small Seljuk castle in the 11th century. The same promontory is also the probable site of the Palace of Mausolos, the famous King of Caria. In his travel diary "Travels In Asia Minor", Charles Boileau Elliot describes this palace as the Palace of Mausolus with absolute certainty, and this account was written in the year 1840.The construction of the castle began in 1404 under the supervision of the German knight architect Heinrich Schlegelholt. Construction workers were guaranteed a reservation in heaven by a Papal Decree.

Bodrum Castle. of 1409. They used squared green volcanic stone, marble columns and reliefs from the nearby Mausoleum of Halicarnassus to fortify the castle.The first walls were completed in 1437. The chapel was among the first completed inner structures (probably 1406). It consists of a vaulted nave and an apse. The chapel was reconstructed in Gothic style by Spanish Knights of Malta in 1519–1520. Their names can be found on two cornerstones of the façade. Fourteen cisterns for collecting rainwater were excavated in the rocks under the castle. This was a monumental achievement of the day and the family who completed the.

Bodrum Castle. excavation were given the honorific of "Burrows" for their exceptional digging skills.Each langue of the Order had its own tower, each in its own style. Each tongue, each headed by a Bailiff, was responsible for the maintenance and defense of a specific portion of the fortress and for manning it with sufficient numbers of knights and soldiers. There were seven gates leading to the inner part of the fortress.The architect applied the latest features in castle design; the passages leading to the gates were full of twists and turns. Eventual assailants could not find cover against the arrows, stones or.

Bodrum Castle. heated projectiles they had to confront. The knights had placed above the gates and on the walls hundreds of painted coats of arms and carved reliefs. Two hundred and forty-nine separate designs still remain, including those of grand masters, castle commandants, countries, and personal coat of arms of knights and religious figures.The construction of the three-storied English tower was finished in 1413. One door opens to the north, to the inner part of the castle, while the other leads to the western rampart. One could only access this tower via a drawbridge. The western façade shows an antique carved relief.

Bodrum Castle. of a lion. Because of this relief, the tower was also called "the Lion Tower". Above this lion, one can see the coat of arms of King Henry IV of England.For over a century St. Peter's Castle remained the second most important castle of the Order. It served as a refuge for all Christians in Asia Minor.The castle came under attack with the rise of the Ottoman Empire, first after the fall of Constantinople in 1453 and again in 1480 by Sultan Mehmed II. The attacks were repelled by the Knights of St John. In 1482, Prince Cem Sultan, son.

Bodrum Castle. of Sultan Mehmed II and brother of Sultan Bayezid II, sought refuge in the castle, after a failure in raising a revolt against his brother.When the Knights decided to fortify the castle in 1494, they used stones from the Mausoleum once again. The walls facing the mainland were thickened in order to withstand the increasing destructive power of cannon. The walls facing the sea were less thick, since the Order had little to fear from a sea attack due to their powerful naval fleet. Grand Master Fabrizio del Carretto (1513–21) built a round bastion to strengthen the land side of.

Bodrum Castle. the fortress. Sir Thomas Docwra was appointed Captain of the Castle in 1499.Despite their extensive fortifications, the Crusaders's towers were no match for the forces of Süleyman the Magnificent, who overpowered the knights in 1523. Under the Ottoman rule, the castle's importance waned, and in 1895 it was converted into a prison.## 16th century.Between 1505 and 1507 the few sculptures from the mausoleum that had not been smashed and burnt for lime were integrated into the castle for decoration. These included twelve slabs of the Amazonomachy (combat between Amazons and Greeks) and a single block of the Centauromachy, a few.

Bodrum Castle. standing lions, and one running leopard.When faced with an attack from Sultan Suleiman, Philippe Villiers de L'Isle-Adam, the Grand Master of the Knights Hospitallers, ordered the Castle to be strengthened again. Much of the remaining portions of the mausoleum were broken up and used as building material to fortify the castle. By 1522 almost every block of the mausoleum had been removed.In June 1522 the sultan attacked the Order's headquarters in Rhodes from the Bay of Marmaris with 200,000 soldiers (Siege of Rhodes (1522)). The castle of Rhodes fell in December 1522. The terms of surrender included the handing over.

Bodrum Castle. of the Knights' fortresses in Kos and St Peter's Castle in Bodrum.After the surrender, the chapel was converted into a mosque and a minaret was added. This mosque was called the "Süleymaniye Camii", as attested by a traveler, Evliya Chelebi, who visited Bodrum in 1671. The minaret was destroyed on 26 May 1915 by rounds fired by a French warship during World War I. It was reconstructed in its original shape in 1997.## 19th century.In 1846 Lord Canning, HM Ambassador to Constantinople, obtained permission to remove twelve marble reliefs showing a combat between Greeks and Amazons from the castle. Sir.

Bodrum Castle. Charles Newton, a member of the staff of the British Museum, conducted excavations and removed a number of stone lions and one leopard in 1856. These are all still to be found today at the British Museum.In later years, the castle has been used for different purposes. It was used as a military base by the Turkish Army during the Greek Revolt in 1824. In the 19th century, the chapel which had been converted for use as a mosque had a minaret added. At the same time, a hamam (public bath) was installed in the castle. In 1895 the castle.

Bodrum Castle. was turned into a prison. During World War I, the castle was fired upon by a French warship, toppling the minaret and damaging several towers. After the Great War, the Italians established a garrison in the castle but withdrew in 1921 when Mustafa Kemal Atatürk came to power, when the castle stood empty for 40 years.## Museum of Underwater Archaeology.In 1962 the Turkish Government decided to turn the castle into a museum for the underwater discoveries of ancient shipwrecks in the Aegean Sea. This has become the Bodrum Museum of Underwater Archaeology, with a collection of amphoras, ancient glass, bronze,.

Bodrum Castle. clay, and iron items. It is the biggest museum of its kind devoted to underwater archaeology. Most of its collection dates from underwater excavations carried out by the Institute of Nautical Archaeology (INA) after 1960. These excavations were performed on several shipwrecks:Finike-Gelidonya shipwreck (12th century BC): 1958–1959; first underwater excavation in Turkey Bodrum-Yassiada shipwreck (Byzantine, 7th century AD): 1961–1964; Roman merchant vessel with 900 amphorasBodrum -Yassiada shipwreck (Late Roman, 4th century AD)Bodrum-Yassiada shipwreck (Ottoman, 16th century AD) (dated by a 16th-century four-real silver coin from Seville (Philip II) )Ṣeytan Deresi shipwreck (16th century BC)Serçe Limanı Shipwreck (glass, 11th century AD):.

Sora (bird). face at the base of the bill and on the throat. Sexes are similar, but young soras lack the black facial markings and have a whitish face and buff breast. They weigh about 49 - 112 (g).The sora's breeding habitat is marshes throughout much of North America. They nest in a well-concealed location in dense vegetation. The female usually lays 10 to 12 eggs, sometimes as many as 18, in a cup built from marsh vegetation. The eggs do not all hatch together. Both parents incubate and feed the young, who leave the nest soon after they hatch and are.

Sexes are similar, but young soras lack the black facial markings and have a whitish face and buff breast. They weigh about 49 - 112 (g) and have a wingspan of 35–40 cm. Soras have two common calls: a loud, squeaking "whinny" that decelerates and descends in pitch, often used to advertise territories; and a softer, ascending "ker-wee" or "sor-ah". The latter call is sometimes presented as.

Sora (bird). York, cover was greater than 70% at 95% of sora nests. In addition, nesting sites had more horizontal cover at 20 inches (0.5 m) above water level than random sites. However, average stem density on sora territories was not significantly (p>0.05) different from random sites in northwestern Iowa.Height of emergent vegetation in sora habitat also varies. It ranged from 8 to 11 (in) in the spring after a winter disturbance in northwestern Iowa to 84 (in) in areas heavily used by soras in Arizona. In marshes of western New York, average vegetation height at sora nesting sites was shorter than.

Odonata. Odonata is an order of flying insects that includes the dragonflies and damselflies. Members of the group first appeared during the Triassic, though members of their total group, Odonatoptera, first appeared in Late Carboniferous.The two common groups are easily distinguished with dragonflies, placed in the suborder Epiprocta, usually being larger, with eyes together and wings up or out at rest, while damselflies, suborder Zygoptera, are usually smaller with eyes placed apart and wings along body at rest.All Odonata have aquatic larvae called nymphs, and all of them, larvae and adults, are carnivorous. The adults can land, but rarely walk. Their.

Odonata. and taxonomy.This order is closely related to mayflies and several extinct orders in a group called the Paleoptera, but this grouping might be paraphyletic. What they do share with mayflies is the nature of how the wings are articulated and held in rest (see insect flight for a detailed discussion).In some treatments, the Odonata are understood in an expanded sense, essentially synonymous with the superorder Odonatoptera but not including the prehistoric Protodonata. In this approach, instead of Odonatoptera, the term Odonatoidea is used. The systematics of the "Palaeoptera" are by no means resolved; what can be said however is that.

Odonata. regardless of whether they are called "Odonatoidea" or "Odonatoptera", the Odonata and their extinct relatives do form a clade.The Anisoptera was long treated as a suborder, with a third suborder, the Anisozygoptera (ancient dragonflies). However, the combined suborder Epiprocta (in which Anisoptera is an infraorder) was proposed when it was found that the "Anisozygoptera" was paraphyletic, composed of mostly extinct offshoots of dragonfly evolution. The four living species placed in that group are (in this treatment) in the infraorder Epiophlebioptera, whereas the fossil taxa that were formerly there are now dispersed about the Odonatoptera (or Odonata "sensu lato"). World Odonata.

Laser printing. Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively-charged cylinder called a "drum" to define a differentially-charged image. The drum then selectively collects electrically-charged powdered ink (toner), and transfers the image to paper, which is then heated to permanently fuse the text, imagery, or both, to the paper. As with digital photocopiers, laser printers employ a xerographic printing process. Laser printing differs from traditional xerography as implemented in analog photocopiers in that in the latter, the image is formed by.

Laser printing. reflecting light off an existing document onto the exposed drum.Invented at Xerox PARC in the 1970s, laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as prices have decreased, and the once cutting-edge printing devices are now ubiquitous.## History.In the 1960s, the Xerox Corporation held a dominant position in the photocopier market. In 1969, Gary Starkweather, who worked in Xerox's product development department, had the idea of using a laser beam to "draw" an image of what was.

Laser printing. to be copied directly onto the copier drum. After transferring to the recently formed Palo Alto Research Center (Xerox PARC) in 1971, Starkweather adapted a Xerox 7000 copier to make SLOT (Scanned Laser Output Terminal). In 1972, Starkweather worked with Butler Lampson and Ronald Rider to add a control system and character generator, resulting in a printer called EARS (Ethernet, Alto Research character generator, Scanned laser output terminal)—which later became the Xerox 9700 laser printer. 1976: The first commercial implementation of a laser printer, the IBM 3800, was released. It was designed for data centers, where it replaced line printers.

Laser printing. Japanese camera and optics company Canon developed the Canon LBP-10, a low-cost desktop laser printer. Canon then began work on a much-improved print engine, the Canon CX, resulting in the LBP-CX printer. Having no experience in selling to computer users, Canon sought partnerships with three Silicon Valley companies: Diablo Data Systems (who rejected the offer), Hewlett-Packard (HP), and Apple Computer. 1981: The first small personal computer designed for office use, the Xerox Star 8010, reached market. The system used a desktop metaphor that was unsurpassed in commercial sales, until the Apple Macintosh. Although it was innovative, the Star workstation was.

Laser printing. a prohibitively-expensive () system, affordable only to a fraction of the businesses and institutions at which it was targeted. 1984: The first laser printer intended for mass-market sales, the HP LaserJet, was released; it used the Canon CX engine, controlled by HP software. The LaserJet was quickly followed by printers from Brother Industries, IBM, and others. First-generation machines had large photosensitive drums, of circumference greater than the loaded paper's length. Once faster-recovery coatings were developed, the drums could touch the paper multiple times in a pass, and therefore be smaller in diameter. 1985: Apple introduced the LaserWriter (also based on.

Laser printing. page is known as a raster line or scan line.Laser printing differs from other printing technologies in that each page is always rendered in a single continuous process without any pausing in the middle, while other technologies like inkjet can pause every few lines. To avoid a buffer underrun (where the laser reaches a point on the page before it has the dots to draw there), a laser printer typically needs enough raster memory to hold the bitmap image of an entire page.Memory requirements increase with the square of the dots per inch, so 600 dpi requires a minimum of.

Laser printing. or 8,388,608 bits, which is just large enough to hold the entire page at 300 dpi, leaving about 100 kilobytes to spare for use by the raster image processor.In a color printer, each of the four CMYK toner layers is stored as a separate bitmap, and all four layers are typically preprocessed before printing begins, so a minimum of 4 megabytes is needed for a full-color letter-size or A4-size page at 300 dpi.During the 1980s, memory chips were still very expensive, which is why entry-level laser printers in that era always came with four-digit suggested retail prices in US dollars.

Laser printing. Memory prices later decreased significantly, while rapid improvements in the performance of personal computers and peripheral cables enabled the development of low-end laser printers which offload rasterization to the sending PC. For such printers, the operating system's print spooler renders the raw bitmap of each page into the PC's system memory at the target resolution, then sends that bitmap directly to the laser (at the expense of slowing down all other programs on the sending PC). The appearance of so-called "dumb" or "host-based" laser printers from NEC made it possible for the retail cost of low-end 600-dpi laser printers to.

Laser printing. decrease to as low as US$700 by early 1994 and US$600 by early 1995.1200 dpi printers have been widely available in the home market since 2008. 2400 dpi electrophotographic printing plate makers, essentially laser printers that print on plastic sheets, are also available.## Charging.In older printers, a corona wire positioned parallel to the drum or, in more recent printers, a primary charge roller, projects an electrostatic charge onto the photoreceptor (otherwise named the photoconductor unit), a revolving photosensitive drum or belt, which is capable of holding an electrostatic charge on its surface while it is in the dark.An AC bias.

Laser printing. silicon nitride.## Exposing.A laser printer uses a laser because lasers are able to form highly-focused, precise, and intense beams of light, especially over the short distances inside of a printer. The laser is aimed at a rotating polygonal mirror which directs the light beam through a system of lenses and mirrors onto the photoreceptor drum, writing pixels at rates up to sixty-five million times per second. The drum continues to rotate during the sweep, and the angle of sweep is canted very slightly to compensate for this motion. The stream of rasterized data held in the printer's memory rapidly turns.

Laser printing. the laser on and off as it sweeps.The laser beam neutralizes (or reverses) the charge on the surface of the drum, leaving a static electric negative image on the drum's surface which will repel the negatively-charged toner particles. The areas on the drum which were struck by the laser, however, momentarily have no charge, and the toner being pressed against the drum by the toner-coated developer roll in the next step moves from the roll's rubber surface to the charged portions of the surface of the drum.Some non-laser printers (LED printers) use an array of light-emitting diodes spanning the width.

Laser printing. uniformly heats the roller from the inside. For proper bonding of the toner, the fuser roller must be uniformly hot.Some printers use a very thin flexible metal foil roller, so there is less thermal mass to be heated and the fuser can more quickly reach operating temperature. If paper moves through the fuser more slowly, there is more roller contact time for the toner to melt, and the fuser can operate at a lower temperature. Smaller, inexpensive laser printers typically print slowly, due to this energy-saving design, compared to large high-speed printers where paper moves more rapidly through a high-temperature.

Laser printing. (on some very fast, expensive printers) a xenon flash lamp. The warmup process that a laser printer goes through when power is initially applied to the printer consists mainly of heating the fuser element.## Malfunctions.The mechanism inside a laser printer is somewhat delicate and, once damaged, often impossible to repair. The drum, in particular, is a critical component: it must not be left exposed to ambient light for more than a few hours, as light is what causes it to lose its charge and will eventually wear it out. Anything that interferes with the operation of the laser such as.

Laser printing. formulations may not match the original specifications in terms of either tendency to accept a negative charge, to move to the discharged areas of the photoreceptor drum from the developer roll, to fuse appropriately to the paper, or to come off the drum cleanly in each revolution.## Performance.As with most electronic devices, the cost of laser printers has decreased significantly over the years. In 1984, the HP LaserJet sold for $3500, had trouble with even small, low-resolution graphics, and weighed 32 (kg). By the late 1990s, monochrome laser printers had become inexpensive enough for home-office use, having displaced other printing.

Laser printing. technologies, although color inkjet printers (see below) still had advantages in photo quality reproduction. , low-end monochrome laser printers can sell for less than $75, and while these printers tend to lack onboard processing and rely on the host computer to generate a raster image, they nonetheless outperform the 1984 LaserJet in nearly all situations.Laser printer speed can vary widely, and depends on many factors, including the graphic intensity of the job being processed. The fastest models can print over 200 monochrome pages per minute (12,000 pages per hour). The fastest color laser printers can print over 100 pages per.

Laser printing. minute (6000 pages per hour). Very high-speed laser printers are used for mass mailings of personalized documents, such as credit card or utility bills, and are competing with lithography in some commercial applications.The cost of this technology depends on a combination of factors, including the cost of paper, toner, drum replacement, as well as the replacement of other items such as the fuser assembly and transfer assembly. Often printers with soft plastic drums can have a very high cost of ownership that does not become apparent until the drum requires replacement.Duplex printing (printing on both sides of the paper) can.

Laser printing. halve paper costs and reduce filing volumes, albeit at a slower page-printing speed because of the longer paper path. Formerly only available on high-end printers, duplexers are now common on mid-range office printers, though not all printers can accommodate a duplexing unit.In a commercial environment such as an office, it is becoming increasingly common for businesses to use external software that increases the performance and efficiency of laser printers in the workplace. The software can be used to set rules dictating how employees interact with printers, such as setting limits on how many pages can be printed per day, limiting.

Laser printing. usage of color ink, and flagging jobs that appear to be wasteful.## Color laser printers.Color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black (CMYK). While monochrome printers only use one laser scanner assembly, color printers often have two or more, often one for each of the four colors.Color printing adds complexity to the printing process because very slight misalignments known as registration errors can occur between printing each color, causing unintended color fringing, blurring, or light/dark streaking along the edges of colored regions. To permit a high registration accuracy, some color laser printers use a.

Laser printing. Color laser transfer printers.Color laser transfer printers are designed to produce transfer media which are transfer sheets designed to be applied by means of a heat press. These transfers are typically used to make custom T-shirts or custom logo products with corporate or team logos on them.2-part Color laser transfers are part of a two-step process whereby the color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black (CMYK); however, newer printers designed to print on dark T-shirts utilize a special white toner allowing them to make transfers for dark garments or dark business products.The CMYK.

Laser printing. color printing process allows for millions of colors to be faithfully represented by the unique imaging process.## Business-model comparison with inkjet printers.Manufacturers use a similar business model for both low-cost color laser printers and inkjet printers: the printers are sold cheaply while replacement toners and inks are relatively expensive. A color laser printer's average running cost per page is usually slightly less, even though both the laser printer and laser toner cartridge have higher upfront prices, as laser toner cartridges print many more sheets relative to their cost than inkjet cartridges. Inkjet printers are better at printing photographs and color.

Laser printing. records, and keeping in mind that there are color laser printers, they're more costly.The print quality of color lasers is limited by their resolution (typically 600–1200 dpi) and their use of just four color toners. They often have trouble printing large areas of the same or subtle gradations of color. Inkjet printers designed for printing photos can produce much higher quality color images. An in-depth comparison of inkjet and laser printers suggest that laser printers are the ideal choice for a high quality, volume printer, while inkjet printers tend to focus on large-format printers and household units. Laser printers offer.

Laser printing. more precise edging and in-depth monochromatic color. In addition, color laser printers are much faster than inkjet printers, although being generally larger and bulkier.## Anti-counterfeiting marks.Many modern color laser printers mark printouts by a nearly invisible dot raster, for the purpose of traceability. The dots are yellow and about 0.1 (mm) in size, with a raster of about 1 (mm). This is purportedly the result of a deal between the US government and printer manufacturers to help track counterfeiters. The dots encode data such as printing date, time, and printer serial number in binary-coded decimal on every sheet of paper.

Laser printing. printer users, this technique also increases waste, and thus increases pressure on the environment. For these toner cartridges (as with inkjet cartridges), reset devices can be used to override the limitation set by the smart chip. Also, for some printers, online walk-throughs have been posted to demonstrate how to use up all the ink in the cartridge. These chips offer no benefit to the end-user—some laser printers used an optical mechanism to assess the amount of remaining toner in the cartridge rather than using a chip to electrically count the number of printed pages, and the chip's only function was.

Laser printing. toner spills into the laser printer, a special type of vacuum cleaner with an electrically conductive hose and a high-efficiency (HEPA) filter may be needed for effective cleaning. These specialized tools are called "ESD-safe" (Electrostatic Discharge-safe) or "toner vacuums".## Ozone hazards.As a normal part of the printing process, the high voltages inside the printer can produce a corona discharge that generates a small amount of ionized oxygen and nitrogen, which react to form ozone and nitrogen oxides. In larger commercial printers and copiers, an activated carbon filter in the air exhaust stream breaks down these noxious gases to prevent pollution.

Laser printing. of the office environment.However, some ozone escapes the filtering process in commercial printers, and ozone filters are not used at all in most smaller home printers. When a laser printer or copier is operated for a long period of time in a small, poorly-ventilated space, these gases can build up to levels at which the odor of ozone or irritation may be noticed. A potential health hazard is theoretically possible in extreme cases.## Respiratory health risks.According to a 2012 study conducted in Queensland, Australia, some printers emit sub-micrometer particles which some suspect may be associated with respiratory diseases. Of 63.

Laser printing. printer emissions with adverse health outcomes were located" and that several assessments conclude that "risk of direct toxicity and health effects from exposure to laser printer emissions is negligible". The review also observes that, because the emissions have been shown to be volatile or semi-volatile organic compounds, "it would be logical to expect possible health effects to be more related to the chemical nature of the aerosol rather than the physical character of the ‘particulate’ since such emissions are unlikely to be or remain as ‘particulates’ after they come into contact with respiratory tissue".The German Social Accident Insurance has commissioned.

Laser printing. a human study project to examine the effects on health resulting from exposure to toner dusts and from photocopying and printing cycles. Volunteers (23 control persons, 15 exposed persons and 14 asthmatics) were exposed to laser printer emissions under defined conditions in an exposure chamber. The findings from the study based on a broad spectrum of processes and subjects fail to confirm that exposure to high laser printer emissions initiates a verifiable pathological process resulting in the reported illnesses.A much-discussed proposal for reducing emissions from laser printers is to retrofit them with filters. These are fixed with adhesive tape to.

Laser printing. the printer's fan vents to reduce particle emissions. However, all printers have a paper output tray, which is an outlet for particle emissions. Paper output trays cannot be provided with filters, so it is impossible to reduce their contribution to overall emissions with retrofit filters.## Air-transport ban.After the 2010 cargo plane bomb plot, in which shipments of laser printers with explosive-filled toner cartridges were discovered on separate cargo airplanes, the US Transportation Security Administration prohibited pass-through passengers from carrying toner or ink cartridges weighing over 1 (lb) on inbound flights, in both carry-on and checked luggage. "PC Magazine" noted that.

Reflecting telescope. A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century by Isaac Newton as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives. Almost all of the major telescopes used in astronomy research are reflectors. Reflecting telescopes come in many design variations and may.

Reflecting telescope. employ extra optical elements to improve image quality or place the image in a mechanically advantageous position. Since reflecting telescopes use mirrors, the design is sometimes referred to as a catoptric telescope.From the time of Newton to the 1800s, the mirror itself was made of metal usually speculum metal. This type included Newton's first designs and even the largest telescopes of the 19th century, the Leviathan of Parsonstown with a 1.8 meter wide metal mirror. In the 19th century a new method using a block of glass coated with very thin layer of silver began to become more popular by.

Reflecting telescope. his telescope and five years before Hooke built the first such Gregorian telescope, Isaac Newton in 1668 built his own reflecting telescope, which is generally acknowledged as the first reflecting telescope. It used a spherically ground metal primary mirror and a small diagonal mirror in an optical configuration that has come to be known as the Newtonian telescope.Despite the theoretical advantages of the reflector design, the difficulty of construction and the poor performance of the speculum metal mirrors being used at the time meant it took over 100 years for them to become popular. Many of the advances in reflecting.

Reflecting telescope. useful for terrestrial observations. Some small spotting scopes are still built this way. There are several large modern telescopes that use a Gregorian configuration such as the Vatican Advanced Technology Telescope, the Magellan telescopes, the Large Binocular Telescope, and the Giant Magellan Telescope.## Newtonian.The Newtonian telescope was the first successful reflecting telescope, completed by Isaac Newton in 1668. It usually has a paraboloid primary mirror but at focal ratios of about f/10 or longer a spherical primary mirror can be sufficient for high visual resolution. A flat secondary mirror reflects the light to a focal plane at the side of.

Reflecting telescope. seldom faster than f/15.## Off-axis designs.There are several designs that try to avoid obstructing the incoming light by eliminating the secondary or moving any secondary element off the primary mirror's optical axis, commonly called off-axis optical systems.## Herschelian.The Herschelian reflector is named after William Herschel, who used this design to build very large telescopes including the 40-foot telescope in 1789. In the Herschelian reflector the primary mirror is tilted so the observer's head does not block the incoming light. Although this introduces geometrical aberrations, Herschel employed this design to avoid the use of a Newtonian secondary mirror since the speculum.

Tughlaqabad Fort. Tughluqabad Fort is a ruined fort in Delhi, built by Ghiyasuddin Tughluq, the founder of the Tughlaq dynasty, of the Delhi Sultanate of India in 1321, as he established the third historic city of Delhi, which was later abandoned in 1327. It lends its name to the nearby Tughluqabad residential-commercial area as well as the Tughluqabad Institutional Area. Ghiyasuddin Tughluq also built the Qutub-Badarpur Road, which connected the new city to the Grand Trunk Road. The road is now known as Mehrauli-Badarpur Road. The entry fee for the Fort is Rs. 20 for Indians. Also, nearby is Dr. Karni Singh.

Anhinga. The anhinga (; Anhinga anhinga), sometimes called snakebird, darter, American darter, or water turkey, is a water bird of the warmer parts of the Americas. The word "anhinga" comes from the Brazilian Tupi language and means "devil bird" or "snake bird". The origin of the name is apparent when swimming: only the neck appears above water so the bird looks like a snake ready to strike. They do not have external nares (nostrils) and breathe solely through their epiglottis.The anhinga is placed in the darter family, Anhingidae, and is closely related to Indian ("Anhinga melanogaster"), African ("Anhinga rufa"), and Australian.

Anhinga. measuring approximately 89 (cm) in length (with a range of 75 - 95 (cm)), with a 1.14 (m) wingspan. The "A. a. anhinga" subspecies is larger than "A. a. leucogaster" and has broader buffy tail tips. They weigh on average around 1.22 (kg), with a range of 1.04 - 1.35 (kg). The bill is relatively long (about twice the length of the head), sharply pointed, and yellow, and the webbed feet are yellow as well.The male is a glossy black-green with the wings, base of wings, and tail a glossy black-blue. The tip of the tail is white. The back.

Anhinga. of the head and the neck have elongated feathers that have been described as gray or light purple-white. The upper back of the body and wings is spotted or streaked with white.The female anhinga is similar to the male except that it has a pale gray-buff or light brown head, neck, and upper chest. The lower chest or breast is a chestnut color, and the back is browner than that of the male.The hatchling starts out bald but gains tan down within a few days of hatching. Within two weeks the tan down is replaced by white down. Three weeks.

Anhinga. after hatching, the first juvenile feathers appear. Juveniles are mostly brown until they first breed usually after the second or third winter.This bird is often mistaken for the double-crested cormorant due to its similar size and shape, although the two species can be differentiated by their tails and bills. The tail of the anhinga is wider and much longer than that of the cormorant. The bill of the anhinga is pointed, while the bill of the cormorant has a hook-tip.## Behavior.Anhingas swim with their webbed feet and pursue their prey, fish, under water and spear their prey by rapidly stretching.

Anhinga. on the water for a short distance, often to avoid any perceived threats. Like cormorants, the anhinga stands with wings spread and feathers fanned open in a semicircular shape, facing away from the sun, to dry its feathers and absorb heat. Anhingas lose body heat relatively fast and their posture helps them absorb solar radiation from the sun to counter this. Because an anhinga in the drying position resembles a male turkey, it has been colloquially referred to as the 'water turkey' or 'swamp turkey'.## Diet.Anhingas feed on moderately sized wetland fishes, amphibians, aquatic invertebrates and insects. In Alabama, the.

Anhinga. stabs it repeatedly and then lets it go. The anhingas bring their capture to the surface of the water, toss it backwards and engulf it head-first.## Conservation status.The anhinga is protected in the US under the Migratory Bird Treaty Act of 1918. The number of individual anhingas has not been estimated but they are considered to be of least concern because of the frequency of their occurrence in their 15000000 (km2) global range.
