Small mammals of the Wolosate area [Bieszczady National Park, SE Poland]

Small mammals were trapped in 12 habitats in 2002 and 2003. In all, 56 individuals of 9 species were caught in 2002, and 751 individuals of 11 species – in 2003. Insectivora communities did not differ statistically significantly in the two consecutive years (trappability index = number of individuals caught/trap-nights number Wo2002 = 1.26%; Wo2003= 0.72%; p<0.01), whereas the Rodentia community differed significantly (Wo2002 = 3.15; Wo2003‘03 = 30.88 p<0.03). In both years, the most numerous among the animals trapped were A. flavicollis and C. glareolus among rodents and S. araneus among insectivores, dominating in almost all habitats. The least diverse group was that of beech forest and alder wood ecotone (Simpson’s dominance index c=0.72 and 0.80 in 2002, and 0.50 and 0.53 in 2003).
