Wolf Lake First Nation
The wolf (''Canis lupus''; : wolves), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of ''Canis lupus'' have been recognized, and gray wolves, as popularly understood, comprise wild subspecies. The wolf is the largest extant member of the family Canidae. It is also distinguished from other ''Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The banded fur of a wolf is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large prey, its more social nature, and its highly advanced ...

Middle Pleistocene
The Chibanian, widely known by its previous designation of Middle Pleistocene, is an age in the international geologic timescale or a stage in chronostratigraphy, being a division of the Pleistocene Epoch within the ongoing Quaternary Period. The Chibanian name was officially ratified in January 2020. It is currently estimated to span the time between 0.770 Ma (770,000 years ago) and 0.126 Ma (126,000 years ago), also expressed as 770–126 ka. It includes the transition in palaeoanthropology from the Lower to the Middle Palaeolithic over 300 ka. The Chibanian is preceded by the Calabrian and succeeded by the proposed Tarantian. The beginning of the Chibanian is the Brunhes–Matuyama reversal, when the Earth's magnetic field last underwent reversal. It ends with the onset of the Eemian interglacial period (Marine Isotope Stage 5). The term Middle Pleistocene was in use as a provisional or "quasi-formal" designation by the International Union of Geological Sciences (IUGS). W ...

Agouti (coloration)
Agouti is a type of fur coloration in which each hair displays two or more bands of pigmentation. The overall appearance of agouti fur is usually gray or dull brown, although dull yellow is also possible. Agouti fur is characterized by an appearance of being composed of hairs of different colors, separate from definite markings (although agouti can appear in combination with other markings, such as spots, stripes or patches). This effect is caused by different ''portions'' of each hair being visible, such that different colors of the hair's banding is seen, despite hairs actually having similar coloration. This effect produces a very distinctive, finely "speckled" appearance similar to "salt and pepper" hair, as well as an iridescent effect very similar to shot silk which causes the overall color to appear to shift subtly depending on the angle of the light or when the animal moves. Agouti fur is the wild type pigmentation for many domesticated mammals. It is a highly recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hooved Mammal
Ungulates ( ) are members of the diverse clade Ungulata which primarily consists of large mammals with hooves. These include odd-toed ungulates such as horses, rhinoceroses, and tapirs; and even-toed ungulates such as cattle, pigs, giraffes, camels, sheep, deer, and hippopotamuses. Cetaceans such as whales, dolphins, and porpoises are also classified as even-toed ungulates, although they do not have hooves. Most terrestrial ungulates use the hoofed tips of their toes to support their body weight while standing or moving. The term means, roughly, "being hoofed" or "hoofed animal". As a descriptive term, "ungulate" normally excludes cetaceans as they do not possess most of the typical morphological characteristics of other ungulates, but recent discoveries indicate that they were also descended from early artiodactyls. Ungulates are typically herbivorous and many employ specialized gut bacteria to allow them to digest cellulose. Some modern species, such as pigs, are omnivoro ...

Carnivore
A carnivore , or meat-eater (Latin, ''caro'', genitive ''carnis'', meaning meat or "flesh" and ''vorare'' meaning "to devour"), is an animal or plant whose food and energy requirements derive from animal tissues (mainly muscle, fat and other soft tissues) whether through hunting or scavenging. Nomenclature Mammal order The technical term for mammals in the order Carnivora is ''carnivoran'', and they are so-named because most member species in the group have a carnivorous diet, but the similarity of the name of the order and the name of the diet causes confusion. Many but not all carnivorans are meat eaters; a few, such as the large and small cats (felidae) are ''obligate'' carnivores (see below). Other classes of carnivore are highly variable. The Ursids, for example: While the Arctic polar bear eats meat almost exclusively (more than 90% of its diet is meat), almost all other bear species are omnivorous, and one species, the giant panda, is nearly exclusively herbivorous. ...

Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pack (canine)
A pack is a social group of conspecific canines. Packs aren't formed by all canines, especially small sized canines like the Red fox. The number of members in a pack and their social behavior varies from species to species. Social structure is very important in a pack. Every pack member will have a position and a role to play. Canine packs are led by a breeding pair, consisting of the alpha male and the alpha female. Pack behavior in specific species African wild dogs (''Lycaon pictus'') live and hunt in packs. Males assist in raising the pups, and remain with their pack for life, while the females leave their birth pack at about the age of two and a half years old to join a pack with no females. Males outnumber the females in a pack, and usually only one female is present to breed with all males. African wild dogs are not territorial, and they hunt cooperatively in their packs, running down large game and tearing it apart. They cooperate in caring for wounded and sick pack membe ...

Mated Pair
Breeding pair is a pair of animals which cooperate over time to produce offspring with some form of a bond between the individuals.Gaston, A. J.The evolution of group territorial behavior and cooperative breeding" The American Naturalist 112.988 (1978): 1091-1100. For example, many birds mate for a breeding season or sometimes for life. They may share some or all of the tasks involved: for example, a breeding pair of birds may split building a nest, incubating the eggs and feeding and protecting the young. The term is not generally used when a male has a harem of females, such as with mountain gorillas. True breeding pairs are usually found only in vertebrates, but there are notable exceptions, such as the Lord Howe Island stick insect. True breeding pairs are rare in amphibians or reptiles, although the Australian Shingleback is one exception with long-term pair-bonds. Some fish form short term pairs and the French angelfish is thought to pair-bond over a long term. True breed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Family
A nuclear family, elementary family, cereal-packet family or conjugal family is a family group consisting of parents and their children (one or more), typically living in one home residence. It is in contrast to a single-parent family, the larger extended family, or a family with more than two parents. Nuclear families typically center on a heterosexual married couple which may have any number of children. There are differences in definition among observers. Some definitions allow only biological children that are full-blood siblings and consider adopted or half and step siblings a part of the immediate family, but others allow for a step-parent and any mix of dependent children, including stepchildren and adopted children. Some sociologists and anthropologists consider the nuclear family as the most basic form of social organization, while others consider the extended family structure to be the most common family structure in most cultures and at most times. The term ''nuclear fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Howling
Howling is a vocal form of animal communication seen in most canines, particularly wolves, coyotes, foxes, and dogs, as well as cats and some species of monkeys. Howls are generally lengthy sustained sounds, loud and audible over long distances, often with some variation in pitch over the length of the sound. Howling is generally used by animals that engage in this behavior to signal their positions to one another, to call the pack to assemble, or to note their territory. The behavior is occasionally copied by humans, and has been noted to have varying degrees of significance in human culture. In canines The long-distance howling of wolves and coyotes is one way in which canines communicate. Long-distance contact calls are common in Canidae, typically in the form of either barks (termed "pulse trains") or howls (termed "long acoustic streams"). Wolves howl to assemble the pack usually before and after hunts, to pass on an alarm particularly at a den site, to locate each o ...

Wolf Communication
Wolves communicate using vocalizations, body postures, scent, touch, and taste. The lunar phases have no effect on wolf vocalisation. Despite popular belief, wolves do not howl at the Moon. Gray 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 or while crossing unfamiliar territory, and to communicate across great distances. Other vocalisations include growls, barks and whines. Wolves do not bark as loudly or continuously as dogs do but they bark a few times and then retreat 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, sleeken their fur, and lower their ears and tail. 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. V ...

Sociality
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies. Sociality is a survival response to evolutionary pressures. For example, when a mother wasp stays near her larvae in the nest, parasites are less likely to eat the larvae. Biologists suspect that pressures from parasites and other predators Natural selection, selected this behavior in wasps of the Family (biology), family Vespidae. This wasp behaviour evidences the most fundamental characteristic of animal sociality: parental investment. Parental investment is any expenditure of resources (time, energy, social capital) to benefit one's offspring. Parental investment detracts from a parent's capacity to invest in future reproduction and aid to Family, kin (including other offspring). An animal that cares for its young but shows no other sociality traits is said to be ''subsocial''. An animal that exhibits a high degree of social ...

Hunting Behavior Of Gray Wolves
Single wolves or mated pairs typically have higher success rates in hunting than do large packs; single wolves have occasionally been observed to kill large prey such as moose, bison and muskoxen unaided. This contrasts with the commonly held belief that larger packs benefit from cooperative hunting to bring down large game. The size of a wolf hunting pack is related to the number of pups that survived the previous winter, adult survival, and the rate of dispersing wolves leaving the pack. The optimal pack size for hunting elk is four wolves, and for bison a large pack size is more successful. As well as their physical adaptations for hunting hoofed mammals, wolves possess certain behavioural, cognitive, and psychological adaptations to assist with their hunting lifestyle. Wolves are excellent learners that match or outperform domestic dogs. They can use gaze to focus attention on where other wolves are looking. This is important because wolves do not use vocalization when hunting. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
