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.

30 St Mary Axe. 30 St Mary Axe (previously known as the Swiss Re Building and informally known as the Gherkin) is a commercial skyscraper in London's primary financial district, the City of London. It was completed in December 2003 and opened in April 2004. With 41 floors, it is 180 (m) tall and stands on the sites of the former Baltic Exchange and Chamber of Shipping, which were extensively damaged in 1992 in the Baltic Exchange bombing by a device placed by the Provisional IRA in St Mary Axe, a narrow street leading north from Leadenhall Street.After plans to build the 92-storey Millennium.

It was erected by Skanska; construction started in 2001.The building has become a recognisable landmark of London, and it is one of the city's most widely recognised examples of contemporary architecture. It won the 2003 Emporis Skyscraper Award.## Site and early plans.The building stands on the site of the former Baltic Exchange (24–28 St Mary Axe), which was the headquarters of a global marketplace for shipping freight contracts and soft commodities, and the Chamber of Shipping (30–32 St Mary Axe). The tower's topmost panoramic.

"The Gherkin" nickname was applied to the current building at least as early as 1999, referring to the plan's highly unorthodox layout and appearance.On 10 April 1992, the Provisional IRA detonated a bomb close to the Baltic Exchange, causing extensive damage to the historic building and neighbouring structures. The United Kingdom government's statutory adviser on the historic environment, English Heritage, and the City of London's governing body,.

30 St Mary Axe. the City of London Corporation, were keen that any redevelopment must restore the Baltic Exchange's old façade onto St Mary Axe. The Exchange Hall was a celebrated fixture of the shipping market.English Heritage then discovered that the damage was far more severe than initially thought, and they stopped insisting on full restoration, albeit over the objections of architectural conservationists. The Baltic Exchange and the Chamber of Shipping sold the land to Trafalgar House in 1995. Most of the remaining structures on the Baltic Exchange site were then carefully dismantled, and the interior of Exchange Hall and the façade were preserved,.

30 St Mary Axe. accepted.## Planning process.John Prescott, the Deputy Prime Minister, granted planning permission on 23 August 2000 to construct a building on the site, which would be much larger than the old Exchange. The site needed development, was not on any of the "sight lines" (planning guidance requires that new buildings do not obstruct or detract from the view of St Paul's Cathedral dome when viewed from a number of locations around London), and had housed the Baltic Exchange.The plan for the site was to reconstruct the Baltic Exchange. GMW Architects proposed a new rectangular building surrounding a restored exchange: it would.

Alligator. America during the early Tertiary or late Cretaceous (about 53 million to about 65 million years ago). The Chinese alligator split from the American alligator about 33 million years ago and likely descended from a lineage that crossed the Bering land bridge during the Neogene. The modern American alligator is well represented in the fossil record of the Pleistocene. The alligator's full mitochondrial genome was sequenced in the 1990s. The full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds.## Phylogeny.The genus "Alligator" belongs to the subfamily Alligatorinae, which is the sister taxon.

Pfäffikersee. Pfäffikersee (or "Lake Pfäffikon") is a lake in the canton of Zürich, Switzerland, near the town of Pfäffikon. It is 2.5 km long and 1.3 km wide at the middle. The lake was created in the last ice age when a moraine blocked off the ability for the lake to empty north towards Winterthur. There is also a hiking trail around the lake that people often bike and walk on, and the area is considered protected lands, among them the "Robenhauser Ried" and the prehistoric settlement Wetzikon–Robenhausen, discovered and researched by Jakob Messikommer (1828–1917), which became a serial site of.

Shortia. Shortia is a small genus of subshrubs or perennial herbs in the family Diapensiaceae. There are five species, four in Asia and one in the Appalachian Mountains of eastern North America. They are found in mountainous areas, generally from 1000 – 2000 (m) elevation. All have restricted ranges and are generally considered rare. Three of the species, "S. galacifolia", "S. soldanelloides", and "S. uniflora" are often cultivated. The genus was by Asa Gray named after botanist Charles Wilkins Short. In Gray's diary entry for April 8, 1839, he named the genus after Charles Wilkins Short because the plant was native.

Dolomedes minor. Dolomedes minor is a spider in the family Pisauridae that is endemic to New Zealand, where it is known as the nursery web spider.## Identification."Dolomedes minor" is pale brown with some being grayish, like the rocks around which they live, helping to camouflage them against predators. (Arnqvist, 1992)The spider has large pedipalps, which are usually used for sensory purposes. The palps in the male "Dolomedes minor" are modified for putting sperm into the female's epigyne, which is located on the underside of the female's abdomen. The female "Dolomedes minor" can easily be identified based on this location of the epigyne.

Dolomedes minor. They possess large chelicerae, which are located just below the eyes. (Andrews, 1986) The spider has a body length of about 18 mm. The females are almost twice the size of the males. They move very fast and possess a long leg-span: over sixty millimeters for a fully grown female.## Natural global range.The family Pisauridae, containing all nursery web spiders, has been estimated to contain over 300 species.## New Zealand range."Dolomedes minor" can be found throughout New Zealand in various vegetation types and altitude ranges.## Habitat preferences."Dolomedes minor" is found in a variety of habitats throughout New Zealand. They survive.

Dolomedes minor. in a variety of terrains, from sea level up to subalpine areas, including shrubland containing Gorse (Ulex europaeus) and Manuka (Leptospermum scoparium), swamps and grasslands. When hunting, they can be seen waiting around the water's edge and active amongst the stones, although they are nocturnal hunters. The spider is noticeable in these areas due to the large white nests thickly webbed to the ends of plants throughout these regions. Females will usually remain with their young in these habitats once their nursery webs have been constructed.## Life cycle and phenology."Dolomedes minor" are most commonly seen through the summer months from.

Dolomedes minor. November to May. Over these months the females have been found with egg-sacs attached to them which are carried for at least 5 weeks in their fangs. After this the female will start to construct her nursery web, which is not made to catch prey but to ‘nurse’ young. This is made at night and built amongst and at the tips of foliage. It can be around six inches or more in length and will house the eggs and young. At night the females guard the web and during the day have been noted to move towards the base of.

Dolomedes minor. the vegetation.The spiderlings will emerge shortly after the webs construction, usually within a week or after they have changed skin, and after two weeks most young would have left the nest. It is presumed this is done by ‘ballooning’ a type of air dispersal to allow them to leave the nest. This air dispersal is done so on long floating strands of silk which can also aid leaving and moving to a variety of geographical boundaries.There has been sightings of adult males with young adult females but no courtship or mating has been recorded. In other "Dolomedes" species, sexual cannibalism.

Dolomedes minor. is high so it is possible that "D. minor" males will try mate with virgin females to avoid this. Hurried copulation (mating) has been found to be common in other "Dolomedes" species also.## Diet and predators.As a nocturnal species, "Dolomedes minor" hunts and scavenges for food at night. The prey spectrum of the spider consists of a variety of small organisms including locusts, other spiders, dobsonfly larvae, earthworms, bees and other small insects (Williams, 1978). Although "Dolomedes" is an effective hunter, previously deceased organisms will also be accepted as food. The spider does not use its web at any point.

Dolomedes minor. during predation, but rather captures prey through methods of hunting. The spider tends to take a passive approach to hunting however, waiting for prey to make contact with it before attacking. Despite having four prominent posterior eyes, "Dolomedes minor" relies entirely on touch and chemical perception rather than sight in the detection of prey. These senses are facilitated by hair sensilla on the spiders body that allow them to detect and capture prey with no reliance on sight. A particular feeding behaviour exhibited by the Nurseryweb spider is the rapid consumption of prey when it is available. Individuals of the.

Dolomedes minor. species have been observed capturing additional prey whilst still feeding on previously taken organisms, as well as commonly capturing and holding multiple insects at a time. This behaviour is thought to have a direct correlation with the nocturnal instinct of "Dolomedes minor", with the need for rapid consumption stemming from the limited availability of prey at night. The number of active insects decreases rapidly after twilight and remains limited until a spike before dawn, this leaves the spiders with only small windows of time in which to capture sufficient prey to nourish themselves.

Bristol Harbour. Bristol Harbour is the harbour in the city of Bristol, England. The harbour covers an area of 70 (acre). It is the former natural tidal river Avon through the city but was made into its current form in 1809 when the tide was prevented from going out permanently. A tidal by-pass was dug for 2 miles through the fields of Bedminster for the river, known as the "River Avon New Cut", "New Cut", or simply "The Cut". It is often called the Floating Harbour as the water level remains constant and it is not affected by the state of the.

Beyond the lock is a junction: on one arm the navigable River Avon continues upstream to Bath, and on the other arm is the tidal natural River Avon. The first 1 (mi) of the floating harbour, downstream from Netham Lock to Totterdown Basin, is an artificial canal known as the Feeder Canal, while the tidal River Avon follows its original.

Bristol Harbour. route. Downstream of Totterdown Basin, the floating harbour occupies the former natural course of the River Avon, whilst the tidal River Avon flows through an artificial channel known as the New Cut. This separation of the floating harbour and the tidal River Avon allows boats in the harbour to remain floating at low tide, reduces currents and silting and prevents flooding.Between Bristol Temple Meads railway station and Hotwells, the harbour and the River Avon run parallel at a distance of no more than 5/8 (mi) apart. Downstream of Bristol Temple Meads railway station, the floating harbour meanders through Bristol city.

Bristol Harbour. centre, Canon's Marsh and Hotwells. At Hotwells, the floating harbour rejoins the tidal River Avon, via a series of locks, and flows into the Avon Gorge.Bristol Harbour was the original Port of Bristol, but as ships and their cargo have increased in size, it has now largely been replaced by docks at Avonmouth and Portbury. These are located 7 (mi) downstream at the mouth of the River Avon.## History of Bristol docks.Bristol grew up on the banks of the Rivers Avon and Frome. Since the 13th century, the rivers have been modified for use as docks including the diversion of.

Bristol Harbour. the River Frome in the 1240s into an artificial "deep channel" known as "Saint Augustine's Reach", which flowed into the River Avon. Saint Augustine's Reach became the heart of Bristol's docks with its quays and wharfs. The River Avon within the gorge, and the River Severn into which it flows, has tides which fluctuate about 30 (ft) between high and low water. This means that the river is easily navigable at high tide but reduced to a muddy channel at low tide in which ships would often run aground. Ships had no option but to be stranded in the harbour.

Bristol Harbour. for unloading, giving rise to the phrase "shipshape and Bristol fashion" to describe how ships and their secured cargo were capable of taking the strain of repeated strandings on the mud.As early as 1420, vessels from Bristol were regularly travelling to Iceland and it is speculated that sailors from Bristol had made landfall in the Americas before Christopher Columbus or John Cabot. After Cabot arrived in Bristol, he proposed a scheme to the king, Henry VII, in which he proposed to reach Asia by sailing west across the north Atlantic. He estimated that this would be shorter and quicker than.

Bristol Harbour. Columbus' southerly route. The merchants of Bristol, operating under the name of the Society of Merchant Venturers, agreed to support his scheme. They had sponsored probes into the north Atlantic from the early 1480s, looking for possible trading opportunities. In 1552 Edward VI granted a Royal Charter to the Merchant Venturers to manage the port.By 1670, the city had 6,000 tons of shipping, of which half was used for importing tobacco. By the late 17th century and early 18th century, this shipping was also playing a significant role in the slave trade.## Construction of the floating harbour.In the 18th century,.

Bristol Harbour. the docks in Liverpool grew larger and so increased competition with Bristol for the tobacco trade. Coastal trade was also important, with the area called "Welsh Back" concentrating on trows with cargoes from the slate industry in Wales, stone, timber and coal. The limitations of Bristol's docks were causing problems to business, so in 1802 William Jessop proposed installing a dam and lock at Hotwells to create the harbour. The £530,000 scheme was approved by Parliament, and construction began in May 1804. The scheme included the construction of the Cumberland Basin, a large wide stretch of the harbour in Hotwells.

Bristol Harbour. where the Quay walls and bollards have listed building status.The tidal new cut was constructed from Netham to Hotwells, with another dam installed at this end of the harbour. The Feeder Canal between Temple Meads and Netham provided a link to the tidal river so that boats could continue upstream to Bath. However, the new scheme required a way to equalise the levels inside and outside the Dock for the passage of vessels to and from the Avon, and bridges to cross the water. Jessop built Cumberland Basin with two entrance locks from the tidal Avon, of widths 45 and.

Bristol Harbour. 35 (ft), and a 45 (ft) junction lock between the Basin and what became known as the Floating Harbour. This arrangement provided flexibility of operation with the Basin being used as a lock when there were large numbers of arrivals and sailings. The harbour was officially opened on 1 May 1809. The first vessel built in the Floating Harbour was .Patterson's yard within the harbour was used for the construction of many ships notably Brunel's in 1838 and the in 1843. They were some of the largest ships to have been built at the time, and ironically hastened the decline.

The SS "Great Britain" was to be towed away from her builders, to have her 1,000 hp engines and interior fitted out on the River Thames, but her 48 (ft) beam was too big to pass through the lock. Thus the SS "Great Britain" was moored in the Floating Harbour until December 1844, before proceeding into Cumberland Basin after coping stones and lock gate platforms were removed from the Junction Lock. At one time there were dozens of Bristol shipyards, the largest in the harbour being Hilhouse, who became.

Charles Hill & Sons in 1845.## 19th century improvements.The harbour cost more than anticipated and high rates were levied to repay loans, reducing any benefit the new harbour had at drawing companies back from Liverpool. In 1848 the city council bought the docks company to force down the rates. They employed Isambard Kingdom Brunel to make improvements, including new lock gates, a dredger and sluice gates designed to reduce siltation.By 1867, ships were getting larger and the meanders in the river Avon prevented vessels over 300 (ft) from reaching the harbour. A scheme to install a much larger lock at.

The present entrance lock was designed by Thomas Howard and opened in July 1873. This has a width of 62 (ft) and is the only entrance lock now in use at the City Docks.From 1893 until 1934 the Clifton Rocks Railway provided a funicular railway link, inside the cliff face, from the western end of the harbour, which is close to the locks, into Clifton.## Railways.The original Bristol Harbour Railway was.

Bristol Harbour. a joint venture by the GWR and the Bristol and Exeter Railway, opened in 1872 between Temple Meads and the Floating Harbour. Its route included a tunnel under St Mary Redcliffe church and a steam-powered bascule bridge over the entrance locks at Bathurst Basin. In 1876 the railway was extended by 1/2 (mi) to Wapping Wharf. In 1906, new branches from the south via the Ashton Avenue swing bridge were built to Canons Marsh on the north side of the Floating Harbour and to Wapping via a line alongside the New Cut. A Coal Concentration Depot owned by Western Fuels.

Bristol Harbour. was established at Wapping Wharf just behind the Industrial Museum but this closed in 1987.## Underfall Yard.The docks maintenance facility was established on the land exposed by the damming of the river to construct the harbour and remains sited at this location to the present day. William Jessop had created a weir in the dam at Underfall to allow surplus water to flow back into the New Cut, this was known as the 'Overfall'. By the 1830s, the Floating Harbour was suffering from severe silting. Isambard Kingdom Brunel was, however, able to devise a solution to this problem. In place.

Bristol Harbour. of the Overfall he advised better use of three shallow sluices and one deep scouring sluice between the harbour and the New Cut, together with a dredging vessel. This drag boat would scrape the silt away from the quay walls. When the deep sluice opened at low tide, a powerful undertow sucked the silt into the river to be carried away on the next tide. The shallow sluices enabled adjustment of the dock water level according to weather conditions.Several old buildings, which date from the 1880s, remain at Underfall Yard and have listed building status. The octagonal brick and terracotta.

Great kiskadee. Tobago in about 1970.## Taxonomy.The great kiskadee was described and illustrated in 1648 by the German naturalist Georg Marcgrave in the "Historia Naturalis Brasiliae". He used the name , the word for a large flycatcher in the Tupi language. In 1760 the French zoologist Mathurin Jacques Brisson included a description of the species in his "Ornithologie" based on a specimen collected in Cayenne, French Guiana. He used the French name and the Latin name . Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. At.

Great kiskadee. The nest is placed in a wide range of sites, often in an exposed position high up in a tree or on man-made structures. Occasionally the nest is placed in a cavity. The clutch is 3 to 4 eggs. These are moderately glossy, light yellowish cream in colour with purplish black and purplish brown spots. The average size is 27.9 x 20.0 (mm). Only the female incubates the eggs; the male guards the nest while she leaves the nest to feed. The eggs hatch after 16–17 days. The chicks are fed by both parents and fledge after 17–18 days.## Food.

Adventfjorden. Adventfjorden (Advent Bay) is a 7 km long and 4 km wide bay running south-eastwards from the southern side of Isfjorden, on the west coast of Spitsbergen in Svalbard. The name represents a corruption of "Adventure Bay" - probably named after the Hull-built whaleship "Adventure", which operated in Isfjorden in 1656. The fjord was originally known as "Klass Billen Bay". At the head of Adventfjorden is Adventdalen (Advent Valley).The former mining-camp of Longyearbyen (now Svalbard's main town) lies on the fjord's southwestern shore, while another former mining-camp, Hiorthhamn, is located on its northeastern shore.Conway, W.

Galium odoratum. Galium odoratum, the sweet woodruff or sweetscented bedstraw, is a flowering perennial plant in the family Rubiaceae, native to much of Europe from Spain and Ireland to Russia, as well as Western Siberia, Turkey, Iran, the Caucasus, China and Japan. It is also sparingly naturalized in scattered locations in the United States and Canada. It is widely cultivated for its flowers and its sweet-smelling foliage.A herbaceous plant, it grows to 30 - 50 (cm) long, often lying flat on the ground or supported by other plants.It owes its sweet smell to the odoriferous agent coumarin, and is sometimes used as.

Galium odoratum. a flavouring agent due to its chemical content.## Description.The leaves are simple, lanceolate, glabrous, 2 - 5 (cm) long, and borne in whorls of 6–9. The small (4–7 mm diameter) flowers are produced in cymes, each white with four petals joined together at the base. The fruits are 2–4 mm diameter, produced singly, and each is covered in tiny hooked bristles which help disperse them by sticking temporarily to clothing and animal fur.This plant prefers partial to full shade in moist, rich soils. In dry summers it needs frequent watering. Propagation is by crown division, separation of the rooted stems,.

Galium odoratum. or digging up of the barely submerged perimeter stolons. It is ideal as a groundcover or border accent in woody, acidic gardens where other shade plants fail to thrive. Deer and chickens avoid eating it (Northeast US).## Uses and health risks.As the epithet "odoratum" suggests, the plant is strongly scented, the sweet scent being derived from coumarin. This scent increases on wilting and then persists on drying, and the dried plant is used in potpourri and as a moth deterrent. It was, and partially is, used to flavour May wine (called "Maibowle" or "Maitrank" in German/French), sweet juice punch, syrup.

Galium odoratum. for beer (Berliner Weisse), brandy, jelly, jam, a soft drink (Tarhun, which is Georgian), ice cream, and herbal tea. Also very popular are sweet woodruff flavoured jellies, with and without alcohol. In Germany, it was and to some extent still is also used to flavour sherbet powder, which features prominently in Günter Grass' novel "The Tin Drum".However, the usage of the plant for sweets was prohibited in Germany in 1974, due to coumarin, the flavorant found in woodruff, being toxic to rats and mice in studies. It has however not been found to be harmful to humans, even in large.

Galium odoratum. doses, in which it follows a different metabolic pathway. The flavour is still popular for sweets in Germany, but is achieved artificially with 6-methyl coumarin. Products targeted towards adults, such as alcoholic drinks, are still permitted to include coumarin, in limited quantities.Plants for a FutureUSDA plants profileMissouri Botanical Gardens Plant Finder.

Steller sea lion. The Steller sea lion (Eumetopias jubatus), also known as the Steller's sea lion and northern sea lion, is a near-threatened species of sea lion in the northern Pacific. It is the sole member of the genus "Eumetopias" and the largest of the eared seals (Otariidae). Among pinnipeds, it is inferior in size only to the walrus and the two species of elephant seals. The species is named for the naturalist Georg Wilhelm Steller, who first described them in 1741. The Steller sea lion has attracted considerable attention in recent decades, owing to significant and largely unexplained declines in their numbers.

Steller sea lion. over an extensive portion of their northern range in Alaska.## Description.Adult animals are lighter in color than most sea lions, ranging from pale yellow to tawny and occasionally reddish. Steller sea lion pups are born almost black, weighing around 23 (kg), and remain dark in coloration for several months. Females and males both grow rapidly until the fifth year, after which female growth slows considerably. Adult females measure 2.3 - 2.9 (m) in length, on average being 2.5 (m), and weigh 240 - 350 (kg), with an average of 263 (kg). Males continue to grow until their secondary sexual traits.

Steller sea lion. appear in their fifth to eighth year. Males are slightly longer than the females, growing to about 2.82 – 3.25 (m) long and averaging 3 (m) in length. Males have much wider chests, necks, and general forebody structure. Males can weigh between 450 – 1120 (kg), weighing on average 544 (kg). Males are further distinguished from females by broader and higher foreheads, flatter snouts, and a thick mane of coarse hair around their large necks. It is fitting then that their Latin name translates roughly as "maned one with the broad forehead".## Range.The range of the Steller sea lion extends.

Steller sea lion. from the Kuril Islands in the Sea of Okhotsk in Russia to the Gulf of Alaska in the north, down to Año Nuevo Island off the coast of central California to the south. They formerly bred as far south as the Channel Islands, but have not been observed there since the 1980s. Based on genetic anаlyses and local migration patterns, the global Steller sea lion population has traditionally been divided into an eastern and western stock at 144°W longitude, roughly through the middle of the Gulf of Alaska. Recent evidence suggests the sea lions in Russia in the Sea of.

Steller sea lion. Okhotsk and the Kuril Islands comprise a third Asian stock, while the sea lions on the eastern seaboard of Kamchatka and the Commander Islands belong to the western stock.In the summer, Steller sea lions tend to shift their range somewhat southward. Therefore, though there are no reproductive rookeries in Japan, several consistent haul-out sites are found around Hokkaidō in the winter and spring. Vagrants have been spotted in the Yellow Sea and Bohai Gulf and along the coast of Korea and China. The oldest fossil known of the species was found near Kanazawa, Japan and dates to the late Early.

Steller sea lion. Pleistocene (0.8 Ma).## Ecology.## Habitat.Steller sea lions tend to live in the coastal waters of the subarctic because of the cooler temperate climate of the area. Like all otariids, Steller sea lions are amphibious and spend some time in water and some on land. Typically, Stellar sea lions spend their time in the water feeding but haul-out onto land to reproduce, raise their pups, molt, and rest. Steller sea lions usually congregate on isolated islands because they are the ideal terrestrial habitat. These isolated islands are preferred by Stellar sea lions because they can avoid predation from terrestrial predators, easily.

Steller sea lion. thermoregulate (by means of cooling winds), and access offshore prey more easily. Some haul-out sites, known as rookeries, are commonly used for reproduction while other haul-out sites are used for other purposes like molting. However, both biotic and abiotic factors can influence the amount of time that Steller sea lions spend on land. Haul-out sites and haul-out abundance of the Steller sea lion can be determined by prey availability, predator abundance, tide levels, weather, etc.## Foraging.Steller sea lions are skilled and opportunistic marine predators, feeding on a wide range of fish and cephalopod species. Important diet components include walleye pollock,.

Steller sea lion. Atka mackerel, halibut, herring, capelin, flatfish Pacific cod, rockfish, sculpins, salmon, sand lance, and cephalopods such as various squid and octopus. They seem to prefer schooling fish and forage primarily between intertidal zones and continental shelves. They usually aggregate in groups of up to twelve in areas of prey abundance. They are known to aggregate near fishing vessels, preying on bycatch discards. Most of the data on their foraging comes from data collected off the coast of Alaska; little is known of their foraging behavior elsewhere.The composition of the diet of Steller sea lions varies seasonally and geographically; as opportunistic.

Steller sea lion. predators, they concentrate on the locally most abundant prey species. In addition to their primary marine environment, they sometimes enter estuaries and feed on brackish-water fish such as sturgeon. Very occasionally, they have been known to prey on northern fur seals, harbor seals, and sea otter pups. Records suggest that the range of their prey species has broadened over time.## Predation.Steller sea lions are top-tier carnivores, but are susceptible to predation, primarily by killer whales. Shark species are also possible predators: sleepers and great whites may prey on juvenile sea lions.## Behavior and life history.## Reproduction.Reproductively mature male sea lions.

Steller sea lion. gather together mid-spring on traditional, well-defined reproductive rookeries, usually on beaches on isolated islands. The larger, older males establish and defend distinct territories on the rookery. A week or so later, adult females arrive, accompanied occasionally by sexually immature offspring, and form fluid aggregations throughout the rookery. Like all other otariids, Steller sea lions are polygynous. However, unlike some other species, they do not coerce individual females into harems, but control spatial territories among which females freely move. Steller sea lions have used aquatic, semiaquatic, and terrestrial territories. Males with semiaquatic territories have the most success in defending them. The.

Steller sea lion. boundaries are defined by natural features, such as rocks, faults, or ridges in rocks, and territories can remain stable for 60 days. Though Steller sea lion males are generally tolerant of pups, one male filmed on Medny Island in Russia was documented killing and eating several pups in a first-ever recorded incident of cannibalism. Though researchers are uncertain as to the motives or reasons behind said attacks, it is suggested that the bull involved may have an abnormal personality akin to being psychotic.Pregnant females give birth soon after arriving on a rookery, and copulation generally occurs one to two weeks.

Steller sea lion. after giving birth, but the fertilized egg does not become implanted in the uterus until the fall. A fertilized egg may remain in embryonic diapause for up to three months before implanting and beginning to divide. Twins are rare. After a week or so of nursing without leaving the rookery, females begin to take progressively longer and more frequent foraging trips leaving their pups behind until at some point in late summer, when both the mother and pup leave the rookery together. This maternal attendance pattern is common in otariids. As pups get older the amount of time spent by.

Steller sea lion. females foraging out at sea increases. This continues until pups obtain the ideal body weight and energy reserves to eat on their own. A study conducted by the University of California, Santa Cruz found that on average male pups consume more milk than females. This may be due to the sexual dimorphism common to otariids. Reproductive males fast throughout the reproductive season, often without entering the water once from mid-May until August, when the structure of the reproductive rookeries begins to fall apart and most animals leave for the open seas and disperse throughout their range.The age at weaning is.

Steller sea lion. highly variable; pups may remain with their mothers for as long as four years. Incidents of mothers feeding daughters that are simultaneously feeding their own newborn pups have been documented, which is an extremely rare occurrence among mammals. A study done at Año Nuevo in 1983 found that female attendance and time spent with their pup was shaped by increasing nutritional demands of the pup and the pups suckling efficiency. Females averaged 21 hours ashore and 36 hours at sea. As the pups aged, females began to spend more time at sea again. As the pups matured, specifically at the.

Steller sea lion. sixth week past birth, the mother's sea time declined by 30 percent. There was no relationship between the pups' activity or physical excursion and their suckling time, age, or sex. Their suckling time, and age, and sex are unrelated to their use of energy. Labeled water studies showed that the pups' milk intake had a direct relationship to their size. Pups that consumed more milk were heavier than those that didn't. These findings show that the amount of time females spend onshore with their pups is based on their pup's suckling efficiency and nutritional demands.In the past, the low pup.

Steller sea lion. production has been tied to an increase in nutritional stress found in females. This was believed to have contributed to the decline in Steller sea lions common to Alaska.## Locomotion.The largest of the eared seals, Steller sea lions are quick swimmers, about as fast as the smaller California sea lions. Glide velocity of individual Steller sea lions has been measured as 2.9–3.4 meters or 1.2–1.5 body lengths per second, which is close to the optimal swim velocity of 1.4 body lengths per second based on the minimum cost of transport for California sea lions.A 2007 study of Steller sea lions.

Steller sea lion. found that a majority of thrust was produced during the drive phase of the fore flipper stroke cycle. Although previous findings on eared seals suggested that thrust was generated by the initial outward movement of the foreflippers or the terminal drag-based paddling phase, the 2007 study found that little or no thrust was generated during those phases. Swimming performance in sea lions is modulated by changes in the duration and intensity of movements without changing their sequence. Using criteria based on velocity and the minimum radius of turns, Steller's maneuverability is similar to other eared seals, superior to cetaceans, and.

Steller sea lion. inferior to many fish.## Diving.To be able to dive for a long period of time, Steller sea lions exhibit apnea, bradycardia, and peripheral vasoconstriction. This allows them to maximize their oxygen stores and efficiently forage during their dives. In addition to those adaptations, their thick blubber layer and outer fur layer keep their body insulated during dives.Trained Steller sea lions from Vancouver Aquarium were placed in the open ocean at the University of British Columbia's Open Water Research Station to study their diving metabolism and behavior. Steller sea lions' dives are more energetically costly if they perform dive bouts. The.

Steller sea lion. aerobic diving limit of Steller sea lions was observed to be affected by their nutritional state and feeding.## Communication.Like most otariids, Steller sea lions are vocal in air. Mature male sea lions have a range of vocalizations as part of their territorial behaviors, including belches, growls, snorts, and hisses that serve as warnings to others. Both males and females also produce underwater noises similar to their above water sounds, described as clicks, barks, and belches. The primary function of their vocalizations is for social behavior. Sonogram readings reported that Steller Sea Lions make discrete, low frequency pulses underwater that resemble.

Steller sea lion. the male "belching" territorial noise made in air. These underwater vocalizations have an average of 20–30 pulses per second.Vocalizations are critical to mother-pup pairs, as the mothers must find their pups in a crowded breeding area when they return from foraging. The mother and pup both use distinctive calls, like names, to help differentiate themselves among the crowd of other sea lions. Their aerial vocalizations have been described as similar to the bleats of sheep, and bellows.Because Steller sea lions are sexually dimorphic in size, their hearing differs in sensitivity, possibly due to differences in size of the hearing structures.

Steller sea lion. Females have a higher sensitivity than males, perhaps to hear the higher frequency calls of their pups. The Steller sea lion's hearing range also suggests that they are capable of hearing the underwater calls of one of their main predators, the killer whale.## Interactions with humans.Steller sea lion were hunted for meat and other commodities by prehistoric communities everywhere their range intersected with human communities. Aside from food and clothing, their skin was used to cover baidarkas and kayaks. A subsistence harvest on the order of 300 animals or less continues to this day in some native communities in Alaska.Historically,.

Steller sea lion. the sea lion has had only very slight commercial value. For example, in the 19th century their whiskers sold for a penny apiece for use as tobacco-pipe cleaners.Steller sea lions are sometimes killed intentionally by fishermen, as they are seen as competitors and a threat to fish stocks. Killing sea lions is strictly prohibited in the US and Russia, but in Japan a fixed number are still removed annually, ostensibly to protect their fisheries. In Canada, commercial hunting is prohibited, but limited hunting permits are occasionally granted if local culling is required—for example, nuisance animals destroying fish farms.In recent years,.

Steller sea lion. Steller sea lions have been known to enter the Columbia River estuary and feed on white sturgeon, several salmon species, and rainbow trout, some of which are also listed under the U.S. Endangered Species Act. They are found in the Columbia River nearly year round, with the exception of early summer, going as far upstream as Bonneville Dam. Though not as abundant as the California sea lion, they are still a concern for those agencies charged with managing the fish populations. Since the Steller sea lions are themselves protected under the Marine Mammal Protection Act, managers are compelled to use.

Steller sea lion. nonlethal deterrence methods, such as rubber bullets and noisemakers. Deterrence by the public is strictly forbidden.## Recent decline and subsequent recovery.While the populations of the eastern and Asian stocks appear stable, the population of the western stock, particularly along the Aleutian Islands, was estimated to have fallen by 70–80% since the 1970s. As a consequence, in 1997 the western stock of Steller sea lions was listed as endangered and the eastern stock was listed as threatened under the United States Endangered Species Act. They have since been the object of intense study and the focus of much political and scientific.

Steller sea lion. debate in Alaska.One suspected cause of their precipitous decline was the overfishing of Alaska pollock, herring, and other fish stocks in the Gulf of Alaska. This stems largely from the "junk-food hypothesis" representing a shift in their diet from fatty herring and capelin to leaner fare such as pollock and flounder, thereby limiting their ability to consume and store fat. Other hypotheses include increased predation by orcas and sharks, indirect effects of prey species composition shifts due to changes in climate, effects of disease or contaminants, shooting by fishermen, and others. The decline is certainly due to a complex of.

Steller sea lion. interrelated factors which have yet to be defined by the research effort.Another possible reason for decline in this species has been tied to the Nutritional Stress Hypothesis. The lack of prey corresponds to the decrease in population. In females specifically, obtaining an insufficient amount of nutrients has resulted in the failure to complete their pregnancies to full term.In October 2013, the eastern Steller sea lion was taken off the U.S. Endangered Species List after a major population comeback over the past several years.Eared seal Marine Mammal Center – Steller Sea Lion US National Marine Fisheries Service Steller Sea Lion web.

Gannet. Gannets are seabirds comprising the genus Morus in the family Sulidae, closely related to boobies.Gannets are large white birds with yellowish heads; black-tipped wings; and long bills. Northern gannets are the largest seabirds in the North Atlantic, having a wingspan of up to 2 (m). The other two species occur in the temperate seas around southern Africa, southern Australia, and New Zealand.## Etymology."Gannet" is derived from Old English "ganot" meaning "strong or masculine", ultimately from the same Old Germanic root as "gander".## Taxonomy."Morus" is derived from Ancient Greek "moros" "stupid" or "foolish" due to lack of fear shown by breeding.

Gannet. gannets and boobies, allowing them to be easily killed.## Behaviour.## Hunting.Gannets hunt fish by diving into the sea from a height of 30 (m) and pursuing their prey underwater, and have a number of adaptations: They have no external nostrils; they are located inside the mouth, instead. They have air sacs in the face and chest under the skin, which act like bubble wrap, cushioning the impact with the water. The position of their eyes is far enough forward on the face for binocular vision, allowing them to judge distances accurately.Gannets can achieve speeds of 100 (km/h) as they strike.

Gannet. the water, enabling them to catch fish at a much greater depth than most airborne birds.The gannet's supposed capacity for eating large quantities of fish has led to "gannet" becoming a description of somebody with a voracious appetite.## Mating and nesting.Gannets are colonial breeders on islands and coasts, normally laying one chalky-blue egg. They lack brood patches and use their webbed feet to warm the eggs. They reach maturity around 5 years of age. First-year birds are completely black, and subsequent subadult plumages show increasing amounts of white.## Northern gannets.The most important nesting ground for northern gannets is the United.
