Popis: | Winter feeding experiments with captive snowshoe hares (Lepus americanus) indicated a mean daily requirement of about 300 g of woody browse having a maximum diameter of 3-4 mm. Food supplies were measured near Rochester, Alberta, during 6 consecutive winters, (1970-71 to 1975-76). Food was insufficient for hare populations on 2 study areas during a cyclic peak (winter 1970-71) and the following winter; food was still in short supply on a 3rd study area 2 winters after the peak. Twenty hare exclosures and their control plots, established in 1968 and sampled in summer 1971 and 1972, showed that hares had reduced the total biomass of woody stems |
