Wolf in the context of Dingoes

The Lupercal (from Latin lupa "female wolf") was a cave at the southwest foot of the Palatine Hill in Rome, located somewhere between the temple of Magna Mater and the Sant'Anastasia al Palatino. In the legend of the founding of Rome, Romulus and Remus were found there by the she-wolf who suckled them until they were rescued by the shepherd Faustulus. Luperci, the priests of Faunus, celebrated certain ceremonies of the Lupercalia at the cave, from the earliest days of the City until at least 494 AD.

The History of Rome, perhaps originally titled Annales, and frequently referred to as Ab Urbe Condita (English: From the Founding of the City), is a monumental history of ancient Rome, written in Latin between 27 and 9 BC by the Roman historian Titus Livius, better known in English as "Livy". The work covers the period from the legends concerning the arrival of Aeneas and the refugees from the fall of Troy, to the city's founding in 753 BC, the expulsion of the Kings in 509 BC, and down to Livy's own time, during the reign of the emperor Augustus. The last event covered by Livy is the death of Drusus in 9 BC. 35 of 142 books, about a quarter of the work, are still extant. The surviving books deal with the events down to 293 BC (books 1–10), and from 219 to 166 BC (books 21–45).

The Big Bad Wolf is a fictional wolf appearing in several cautionary tales, including some of Grimms' Fairy Tales. Versions of this character have appeared in numerous works, and it has become a generic archetype of a menacing predatory antagonist.

A keystone species is a species that has a disproportionately large effect on its natural environment relative to its abundance. The concept was introduced in 1969 by the zoologist Robert T. Paine. Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf and lion, are also apex predators.

The role that a keystone species plays in its ecosystem is analogous to the role of a keystone in an arch. While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measures of biomass or productivity.It became a popular concept in conservation biology, alongside flagship and umbrella species. Although the concept is valued as a descriptor for particularly strong inter-species interactions, and has allowed easier communication between ecologists and conservation policy-makers, it has been criticized for oversimplifying complex ecological systems.

The mammoth steppe, also known as steppe-tundra, was once the Earth's most extensive biome. During glacial periods in the later Pleistocene, it stretched east to west from the Iberian Peninsula in the west of Europe, then across Eurasia and through Beringia (the region including the far northeast of Siberia, Alaska and the now submerged land between them) and into the Yukon in northwest Canada; from north to south, the steppe reached from the Arctic southward to southern Europe, Central Asia and northern China. The mammoth steppe was cold and dry, and relatively featureless—though climate, topography, and geography varied considerably throughout. Certain areas of the biome, such as coastal areas, had wetter and milder climates than others. Some areas featured rivers which through erosion naturally created gorges, gulleys, or small glens. The continual glacial recession and advancement over millennia contributed more to the formation of larger valleys and different geographical features. Overall, however, the steppe is known to be flat and expansive grassland. The vegetation was dominated by palatable, high-productivity grasses, herbs and willow shrubs. Although it was primarily a Eurasian and Beringian biome, an analog of the mammoth steppe existed on the southern edge of the Laurentide ice sheet in North America as well, and contained many of the same animals such as woolly mammoths, muskoxen, scimitar cats, and caribou.

The fauna was dominated by species such as reindeer, muskox, saiga antelope, steppe bison, horses, woolly rhinoceros and woolly mammoth. These herbivores, in turn, were followed and preyed upon by various carnivores, such as wolves, brown bears, Panthera spelaea (the cave or steppe-lion), cave hyenas, wolverines, among others, as well as scimitar-toothed cats and giant short-faced bears in east Beringia (with scimitar-toothed cats also having rare records from the mammoth steppe in Eurasia).

Wakhan National Park is a national park in northeastern Afghanistan. Established in 2014, the park encompasses the entire Wakhan District of Badakhshan Province, extending along the Wakhan Corridor between the Pamir Mountains and the Hindu Kush, bordering the Gorno-Badakhshan autonomous region of Tajikistan to the north, Khyber Pakhtunkhwa and Gilgit-Baltistan in Pakistan to the south, and the Xinjiang autonomous region of China to the east.

Flora and fauna in the Wakhan National Park include some 600 plant species, the snow leopard, lynx, wolf, brown bear, stone marten, red fox, Pallas's cat, ibex, Marco Polo sheep, and urial. Remote and largely above the tree line, poaching and overgrazing, rather than mining and logging, currently pose the main threats. Around 15,000 Afghans of ethnic Wakhi and Kyrgyz background reside in the area. Foreigners must have an Afghan visa to tour the area.

Caniformia is a suborder within the order Carnivora consisting of "dog-like" carnivorans. They include dogs (wolves, foxes, etc.), bears, raccoons, mustelids, and Pinnipedia (seals, walruses and sea lions). The center of diversification for the Caniformia is North America and northern Eurasia. Caniformia stands in contrast to the other suborder of Carnivora, the Feliformia ("cat-like" carnivorans), the center of diversification of which was in Africa and southern Asia.

A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops.

Some animals are disliked because they bite or sting; wolves, snakes, wasps, ants, bees, bed bugs, mosquitos, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food; beetles, which tunnel into the woodwork; and other animals that scuttle about on the floor at night, like rats, mice, and cockroaches, which are often associated with unsanitary conditions.

The domestication of the dog was the process which led to the domestic dog. This included the dog's genetic divergence from the wolf, its domestication, and the emergence of the first dogs. Genetic studies suggest that all ancient and modern dogs share a common ancestry, descending from an ancient, now-extinct wolf population – or closely related wolf populations – which was distinct from the modern wolf lineage. The dog's similarity to the grey wolf is the result of substantial dog-into-wolf gene flow, with the modern grey wolf being the dog's nearest living relative. An extinct Late Pleistocene wolf may have been the ancestor of the dog.

The dog is a wolf-like canid. The genetic divergence between the dog's ancestor and modern wolves occurred between 20,000 and 40,000 years ago, just before or during the Last Glacial Maximum (20,000–27,000 years ago). This timespan represents the upper time-limit for the commencement of domestication because it is the time of divergence but not the time of domestication, which occurred later.

In folklore, a werewolf (from Old English werwulf 'man-wolf'), or occasionally lycanthrope (from Ancient Greek λυκάνθρωπος 'wolf-human'), is an individual who can shapeshift into a wolf or therianthropic hybrid wolf–humanlike creature, either voluntarily or involuntarily due to a curse or other affliction. In modern fiction, especially film, transformations are often depicted as triggered by the full moon and transmitted by a bite or scratch from another werewolf. Early sources for belief in this ability or affliction, called lycanthropy, are Petronius (27–66) and Gervase of Tilbury (1150–1228).

The werewolf is a widespread concept in European folklore, existing in many variants, which are related by a common development of a Christian interpretation of underlying European folklore developed during the Middle Ages. From the early modern period, werewolf beliefs spread to the Western Hemisphere with colonialism. Belief in werewolves developed in parallel to the belief in witches during the late Middle Ages and the early modern period. Like the witchcraft trials as a whole, the trial of supposed werewolves emerged in what is now Switzerland, especially the Valais and Vaud, in the early 15th century and spread throughout Europe in the 16th, peaking in the 17th and subsiding by the 18th century.

Canis is a genus of the Caninae which includes multiple extant species, such as wolves, dogs, coyotes, and golden jackals. Species of this genus are distinguished by their moderate to large size, their massive, well-developed skulls and dentition, long legs, and comparatively short ears and tails.

There are 38 subspecies of Canis lupus listed in the taxonomic authority Mammal Species of the World (2005, 3rd edition). These subspecies were named over the past 250 years, and since their naming, a number of them have gone extinct. The nominate subspecies is the Eurasian wolf (Canis lupus lupus).

The dingo (either included in the species Canis familiaris, or considered one of the following independent taxa: Canis familiaris dingo, Canis dingo, or Canis lupus dingo) is an ancient (basal) lineage of dog found in Australia. Its taxonomic classification is debated as indicated by the variety of scientific names presently applied in different publications. It is variously considered a form of domestic dog not warranting recognition as a subspecies, a subspecies of dog or wolf, or a full species in its own right.

The dingo is a medium-sized canine that possesses a lean, hardy body adapted for speed, agility, and stamina. The dingo's three main coat colourations are light ginger or tan, black and tan, or creamy white. The skull is wedge-shaped and appears large in proportion to the body. The dingo is closely related to the New Guinea singing dog: their lineage split early from the lineage that led to today's domestic dogs, and can be traced back through Maritime Southeast Asia to Asia. The oldest remains of dingoes discovered in Australia are around 3,500 years old.

Canidae (/ˈkænɪdiː/; from Latin, canis, "dog") is a biological family of caniform carnivorans, constituting a clade. A member of this family is a canid (/ˈkeɪnɪd/), colloquially referred to as dogs. The family includes three subfamilies: the Caninae, and the extinct Borophaginae and Hesperocyoninae. The Caninae are the canines, and include domestic dogs, wolves, coyotes, raccoon dogs, foxes, jackals and other species.

Canids are found on all continents except Antarctica, having arrived independently or accompanied by human beings over extended periods of time. Canids vary in size from the 2-metre-long (6.6 ft) gray wolf to the 24-centimetre-long (9.4 in) fennec fox. The body forms of canids are similar, typically having long muzzles, upright ears, teeth adapted for cracking bones and slicing flesh, long legs, and bushy tails. They are mostly social animals, living together in family units or small groups and behaving co-operatively. Typically, only the dominant pair in a group breeds and a litter of young are reared annually in an underground den. Canids communicate by scent signals and vocalizations. One canid, the domestic dog, originated from a symbiotic relationship with Upper Paleolithic humans and is one of the most widely kept domestic animals.

The coyote (Canis latrans) is a species of canine also known as the American jackal, prairie wolf, and brush wolf. It is native to North America, and it is smaller than its close relative, the gray wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia; however, the coyote is generally larger.

The coyote is listed as least concern by the International Union for Conservation of Nature, due to its wide distribution and abundance throughout North America. The species is versatile, able to adapt to and expand into environments modified by humans; urban coyotes are common in many cities. The coyote was sighted in eastern Panama (across the Panama Canal from their home range) for the first time in 2013.

The wild boar (Sus scrofa), also known as the wild swine, common wild pig, Eurasian wild pig, or simply wild pig, is a suid native to much of Eurasia and North Africa, and has been introduced to the Americas and Oceania. The species is now one of the widest-ranging mammals in the world, as well as the most widespread suiform. It has been assessed as least concern on the IUCN Red List due to its wide range, high numbers, and adaptability to a diversity of habitats. It has become an invasive species in part of its introduced range. Wild boars probably originated in Southeast Asia during the Early Pleistocene and outcompeted other suid species as they spread throughout the Old World.

As of 2005, up to 16 subspecies are recognized, which are divided into four regional groupings based on skull height and lacrimal bone length. The species lives in matriarchal societies consisting of interrelated females and their young (both male and female). Fully grown males are usually solitary outside the breeding season. The wolf is the wild boar's main predator in most of its natural range except in the Far East and the Lesser Sunda Islands, where it is replaced by the tiger and Komodo dragon respectively. The wild boar has a long history of association with humans, having been the ancestor of most domestic pig breeds and a big-game animal for millennia. Boars have also re-hybridized in recent decades with feral pigs; these boar–pig hybrids have become a serious pest wild animal in the Americas and Australia.
