Influence of Coyote Predation on Black-Tailed Jackrabbit Populations in Utah

A rapid summer decline in a mountain hare population on an island

“…Christian et a I., 1965; Chitty, 1967) or extrinsic factors such as food, predation and diseases (e.g. Lack, 1954;Wagner & Stoddart, 1972;Keith, 1974). In this paper we will only discuss the extrinsic effects of food in winter and summer, predation i.e.…”

Role of Food in Hare Population Cycles

“…Lidicker's (1975) conception of "presaturation dispersal" and of a "dispersal sink" are obviously highly relevant to this model. Wagner (1981) indicated that fluctuations of blacktailed jackrabbits decrease in amplitude and regularity from northern Utah to southern Arizona. This he ascribed to increased biotic diversity -in particular, a predator complex that has more species, is largely facultative, and fluctuates less.…”

“…When hares and rodents are primary prey, coyotes hunt as singles or pairs. Coyotes may even help truncate the periodically high population density of black-tailed jackrabbits (Wagner and Stoddart 1972). When vertebrate prey are scarce, they readily feed on fruits, nuts, and seeds as well as insects (Meinzer et al 1975).…”
