Analysis of interspecific relationships in mesostigmatid mites (Acari: Mesostigmata) in the nests of the bank vole (Clethrionomys glareolus (Schreber, 1780)).

An analysis is presented of a community of mesostigmatid mites from the nests of Clethrionomys glareolus found in the forest biotopes of Vsetínské Beskydy Mts. (North Moravia) throughout all seasons of the year. Main attention was paid to the structure of the nest community, relationships of mites to their host and interspecific relationships in the mites themselves. Primarily cluster and factor analyses based on correlation matrix were used for mathematical assessment. The particular elements of correlation matrix were Spearman's non-parametric correlation coefficients computed from frequencies of species in the nests studied.
