资源简介：
Densities of snowshoe hares (Lepus americanus Erxleben, 1777) were measured over time to document cyclic changes in hare abundance on the Kenai National Wildlife Refuge. Pellet counts were conducted annually on 5 grids of 49 1 m2 permanent pellet plots. All pellets within the 1 m2 plot were counted and removed. Pellet counts were averaged annually for each grid as an index of snowshoe hare abundance.
