Differentiation of flea communities of small mammals in selected habitats in the Eastern Tatra Mts

Research into small mammals and their ectoparasites was carried out in the Belianske Tatras during 2010–14, evaluating flea communities found on small mammals on the basis of species richness, abundance and level of infestation. Flea infestation of host species occurred mostly in C. glareolus with the highest infestation rates recorded in S. alpinus, the earlier mentioned C. glareolus, N. anomalus and N. fodiens. Based on their prevalence in all the examined hosts, the most frequent flea communities found were M. turbidus, C. agyrtes, A. penicilliger and P. soricis. In addition, flea prevalence in all the captured host species was evaluated. The most frequent flea communities were M. turbidus, P. soricis and D. dasycnema (8 host species); C. agyrtes and H. orientalis (7); A. penicilliger and P. bidentata (4); C. uncinatus, P. sylvatica and R. integela (3); and M. rectangulatus, N. fasciatus and C. bisoctodentatus (2), while A. nuperus and A. arvicolae were recorded in only one host species
