Movements, activity patterns, and habitat use of snowshoe hares (Lepus americanus) in interior Alaska
Snowshoe hares (Lepus americanus) are generally sedentary, but are likely to move among habitats frequently to gain access to spatially segregated food and cover. We investigated movement patterns of hares from 2 characteristic boreal habitats using very-high-frequency radio collars (n 1⁄4 300) monitored weekly and global positioning system (GPS) collars (n 1⁄4 18) programmed to record location...
متن کاملEffects of geophagy on food intake, body mass, and nutrient dynamics of snowshoe hares (Lepus americanus)
Geophagy is thought to have several physiological benefits to animals, including mineral supplementation and adsorption of toxins. However, these benefits have rarely been demonstrated experimentally. Using soil from a known lick in northern Alaska, we investigated the effect of geophagy on food intake andmass loss in captive snowshoe hares (Lepus americanus Erxleben, 1777) fed a formulated rat...
متن کاملChanges in relative abundance of snowshoe hares (Lepus americanus) across a 265-year gradient of boreal forest succession
Understory regeneration within canopy gaps in old-growth boreal forests may provide suitable habitat for wildlife typically associated with early-seral stages, leading to an increase in their abundance in late succession. We surveyed a chronosequence of postfire (17–265 years) and postharvest (3–63 years) stands in Canada’s eastern boreal forest to determine whether snowshoe hares (Lepus americ...
متن کاملThe cold shoulder: free-ranging snowshoe hares maintain a low cost of living in cold climates
The hypothesis that cold air temperatures (Ta) constrain the metabolic diversity of high-latitude endotherms is based on the observation among birds and mammals that mean field metabolic rate (FMR) increases, whereas the variability of FMR decreases, from the warm tropics to the cold poles. However, there is a paucity of FMR measurements from above 608 latitude and below 0 8C. We measured the d...
متن کاملPopulation genetic structure of the cyclic snowshoe hare (Lepus americanus) in southwestern Yukon, Canada.
Spatial population structure has important ecological and evolutionary consequences. Little is known about the population structure of snowshoe hares (Lepus americanus), despite their ecological importance in North American boreal forests. We used seven variable microsatellite DNA loci to determine the spatial genetic structure of snowshoe hares near Kluane Lake, Yukon during a cyclic populatio...
