摘要: We have studied helminths from 532 grey-sided voles (Clethrionomys rufocanus) in two localities northern Finland, representing different biogeographic zones, during 1978–1983. The helminth communities the study areas were similar, characterized by a small number of species (eight) compared to eastern Siberia and Japan, dominance single anoplocephalid cestode Andrya kalelai. prevalence this varied significantly among habitats, possibly because differences distribution abundance intermediate hosts, oribatid mites. Vole density did not explain habitat A. kalelai, nor kalelai increase between 2 yr sustained high host population. A between-year larval Taenia tenuicollis at Kilpisjarvi was probably due simultaneous its definitive mustelids. always higher males; no sexual ...
