Research showed the earliest known dog species, Hesperocyon gregarius, likely pounced on its prey, just like foxes and coyotes. Scientists also determined the largest known dog species, Epicyon haydeni, were the size of grizzly bears. As faster species emerged, their inner ears grew in size. Larger inner ears help cheetahs, lions and wolves keep their head stable while moving at high speeds.

These findings will be useful in modeling wolf population dynamics and in wolf genetic and dog-domestication studies.

Research on wolf packs at Voyageurs National Park in northern Minnesota challenges the conventional wisdom on wolves: Their diets are a lot more varied than scientists previously thought. Researchers with the Voyageurs Wolf Project, a collaboration between the park and the University of Minnesota, have documented wolves hunting freshwater fish as a seasonal food source.

Wolves have a brief life history relative to other large carnivores, including early first reproduction, high fecundity, rapid development, and relatively short lifespans.
Distinguishing Between Coyotes, Wolves, and Dogs. Wolf pups in mid-summer and fall can closely resemble coyotes, and it can be nearly impossible to tell
We attempted to cross-foster four 18-19 week-old Gray Wolf (Canis lupus) pups into another Wolf pack 182 km from their natal pack territory. The pup introduction was the result of depredation control on a farm in northwestern Wisconsin. Three pups died within 14 days of release. A fourth pup survived along the edge of the new pack territory over winter, dispersed in the spring, joined or formed a new pack and was captured on a depredation complaint four years later.
Wolves and other top predators need large ranges to be able to control smaller predators whose populations have expanded to the detriment of a balanced ecosystem.

A TALE OF THREE DOGS
Coyotes, dingoes and wolves are all dogs, as intelligent and loyal as our familiars. Our treatment of them is unconscionable. As a rule, apex predators are the bosses of nature’s regulatory system, promoting ecological richness and stability by suppressing irruptions of prey and smaller predators. ‘They allow the number and variety of species occupying any given area to be higher,’ said Wallach, now a research fellow at the University of Technology Sydney and co-founder with O’Neill of the Dingo for Biodiversity Project. ‘In a nutshell, large predators make the world green.’
