Book Description
Coyotes (Canis latrans) in Yellowstone National Park (YNP) have lived in the absence of wolves (Canis lupus) for over 60 years. I examined whether wolf reintroduction in 1995 and 1996 in YNP influenced coyote vigilance and foraging ecology. From December 1997 to July 2000, my co-workers and I collected 1708 h of coyote activity budgets. Once wolves became established in the Park, they once again provided a continuous source of carrion in the Lamar Valley and we found that coyotes began feeding on carcasses throughout the year. Although we documented that wolves killed coyotes, it also became clear that surviving coyotes quickly adjusted their behaviors when wolves were present. When coyotes were near wolves or in areas of high wolf use, they fed on carcasses much more; however, they increased the amount of time spent in vigilance activities and decreased rest. There appears to be a trade-off in which wolf kills provide a quick source of food that is energetically advantageous to coyotes; however, attendant costs included increased vigilance, decreased rest, and a higher risk of being killed. Changes in the behavior of coyotes in response to the reintroduction of this large carnivore may ultimately have wide-ranging cascading effects throughout the ecosystem.

Effects of 1988 Fires on Ecology of Coyotes in Yellowstone National Park

Book Description
The demographics and social ecology of natural, unexploited coyote populations are, for the most part, unknown. Frank (1979) stated that if a coyote population is subjected to substantial exploitation, neither its social organization nor population dynamics will represent the natural, and therefore evolutionary significant, situation. Recent work in Washington state (Crabtree 1988a, Crabtree and Ables 1989b, Crabtree et al. 1989c) strongly suggests Frank's contention is correct. -1st paragraph.
