And along came the ancestor of the modern day dog, the megafaunal wolf, much bigger and stronger than any wolf today. Megafaunal is the term for many of the larger species of this period. The megafaunal wolf is the ancestor of many canines, or the canis genus, that we know today, such as the jackal, hyena, fox, coyote, dingo, as well as the other wolfs of various regions of the world. We know that the genetic split from this bloodline occurred at this point because of the divergence of genes…

Canis lupus familiaris (dogs) were likely the first animals to be domesticated by humans. Humans and dogs share a long intertwined history. DNA evidence suggests domestic dogs most likely diverged from wolves as long as 135,000 years ago (Udell and Wynne). The American Kennel Club (AKC), a registry of purebred dog pedigrees in the United States, recognizes 167 breeds. Being that dogs are one of the most common household pets owned by humans, it is important to understand their physiology for…

One of the most renowned rewilding projects which has demonstrated the effects rewilding has on a whole ecosystem, was the reintroduction of grey wolves (Canis lupus) into Yellowstone National Park in the North West of the United States. The wolves were reintroduced to the park in 1995-1996 and have subsequently recolonised the whole park and some of the surrounding area known as the greater Yellowstone ecosystem (GYE) (Smith et al., 2003). The reintroduction of the wolves has had a great effect…

Red Wolves The Red wolf, scientifically known as Canis rufus, is a close relative to the more commonly known, Grey wolf. The Grey wolf is the one typically used in fairy tales while the Red wolf is not. The Red wolf has a cinnamon or tawny red coat with some grey and black markings. Their back tends to be darker and their tails tend to have a black tip. Red wolves are smaller than their close relatives, the grey wolf, but have longer legs and shorter fur. Full grown Red wolves measure around 4…

One of the things that distinguish different members of the wolf family (Canis lupus) is the distinctive development of social behavior (Gleason, 2013). Wolves belong to a family or group often referred to as a pack. This structure was originally thought to allow the wolf, a social predator, to take on prey many times its size. New theories, however, are emerging suggesting that the pack strategy maximizes reproductive success and has less to do with hunting (Gleason, 2013). For centuries the…

By the mid-1930’s the gray wolf (Canis lupis) had been extirpated from its natural habitat in Yellowstone National Park through hunting, trapping, and poisoning in attempt to control predator populations (Phillips 1997). Their extirpation allowed elk (Cervus elaphus) populations to reach high numbers because they were no longer mediated by a predator and could not be controlled by human hunting (Kauffman 2010). The park attempted to cull elk numbers after becoming concerned about their impact…

Canis lupus arctos is the scientific name for an arctic wolf. Although many people believe an arctic wolf can only be purely white, this is not true; an arctic wolf may have spots of black, yellow, or gray on its white fur. Due to the location of an arctic wolf, which many experts believe the Ice Age was what made them end up here, they have adapted to this weather. According to A-Z Animals, “ Arctic wolves are incredibly versatile and adaptive animals, able to withstand year round sub-zero…

Wolves (Canis lupus) are one of the most well-known examples of a social animal. The wolf pack possesses a mentality where all members compete for dominance in the group. However the pack’s hierarchy and its strict rules for traversing this hierarchy keep the group from falling apart over constant fighting. L. David Mech (1999) explains how a wild wolf pack is a family, with the adult parents guiding the activities of the group in a division-of-labor system. In this system, the female primarily…
