摘要:
Vegetal habitat characteristics and annual dietary selection were examined for the pygmy rabbit in southeastern Idaho. Areas selected for habitation by pygmy rabbits had a significantly greater woody cover and height than other areas. Total grass-forb biomass was similar in rabbit and nonrabbit sites. Grass biomass was least and forb biomass greatest where pygmy rabbits were most abundant. Sagebrush was eaten throughout the year, although in lesser amounts in summer (51%) than in winter (99%). Grasses and forbs were eaten through the summer (39 and 10%, respectively) and decreased in the diet through fall to winter. Sagebrush is critical to the pygmy rabbit for both food and cover, although in this study, cover and height of woody vegetation appeared to be the critical features of the habitat selected for. This fact should be considered before brush removal treatments are applied within pygmy rabbit range.
