Seasonality of the ectoparasite community of woodland rodents in a Mazurian Forest, Poland.

Myodes glareolus and Apodemus flavicollis support a large and diverse community of arthropod ectoparasites. This study of rodents in a Mazurian woodland sampled at monthly intervals between 2007 and 2009 revealed an ectoparasite community composed of 2 species of tick, 1 louse, 9 flea species, 7 species of gamasid mites, 4 fur mites and one trombiculid mite. A strong seasonality was noted in the dynamics of the ectoparasite community, with the fur mite Listrophorus sp. and the hypopus larva of a glycyphagid mite especially common in winter. Several of the ectoparasites have the potential to be pathogenic; the impact of these organisms on the population dynamics of their hosts remains to be investigated.
