Small browsers, such as snowshoe hare (Lepus americanus
) and eastern cottontails (Silvilagus floridanus), have major impacts early in succession (e.g., Peterson et al, 2005), but large mammals affect growth and mortality for longer time periods (McLaren et al, 2009; Nuttle et al., 2014).
Population genetic structure of the cyclic snowshoe hare (Lepus americanus
) in southwestern Yukon, Canada.
The snowshoe hare (Lepus americanus
) is a keystone prey species of the boreal forest (Krebs, 2011) and experiences regular population cycles that occur over 10-year periods (Krebs et al., 2001).
ABSTRACT--The Canada Lynx (Lynx canadensis) is poorly documented in southwest Alaska, where dominant habitats are generally not conducive to supporting persistent Snowshoe Hare (Lepus americanus
) or Lynx populations.
North America's Lepus americanus
hares may be especially sensitive to climate change.
Mountain hares and snowshoe hares Lepus americanus
both forage to minimise risk, balancing the needs to feed against the risk of exposure to predation (Boutin 1984, Hulbert et al.
In western North America, their diet is dominated by snowshoe hares (Lepus americanus
), black-tailed jackrabbits (Lepus californicus), and ground squirrels (Spermophilus; Fitch et al., 1946; Craighead and Craighead, 1956; Luttich et al., 1970; Smith and Murphy, 1973).
Such cycles in the population density of some mammals are clearly defined, just like happens for Lepus americanus
, whose interval of duration is of eight to ten years, period during which there are population peaks and declines related basically with the supply of food, predation and the leveret survival.
In northern latitudes, the winter coats of the ermine (Mustela erminea) and its prey, the snowshoe hare (Lepus americanus
), are white, making them equally inconspicuous in snowy landscapes.
