Abstract

An ecological study on the seasonal species composition and abundance of rodents was carried out in the farmland, bushland, forest and grassland habitats of Yerer Mountain Forest Area from July 2010 to March 2011. From a total of 3312 trap nights, 402 individuals of small mammals were captured. Out of these, 400 (99.5%) individuals represented 6 species of the family Muridae and whereas the remaining 2 (0.5%) belonged to one shrew species (family Soricidae). The seasonal species composition within each habitat was not significant. But there was significant variation in their relative abundance during wet and dry seasons. High mean trap success (23.5%) and biomass (4151g/hectare) was obtained from the farmland habitat. Number of pregnant females and embryo count showed seasonal variation. Stomach content analysis showed high proportion of plant matter in all samples.
