The Morphological and Molecular Characterization of the Avian Trematodes and (Digenea: Cyclocoelidae) from the Middle Volga Region (European Russia).

The taxonomic status of many species of the family Cyclocoelidae is still unclear. Two species of cyclocoelids, and , were collected from the air sacs of birds ( and ) inhabiting the Middle Volga region (European Russia). Here, we provide the first detailed morphological description of these cyclocoelids and combine it with the first molecular phylogenetic analysis of Cyclocoelidae from birds in Russia based on partial sequences of their 28s rDNA and coI mtDNA genes.

The Diversity of Trematodes in Bats (Chiroptera, Vespertilionidae) from the Samarskaya Luka (European Russia).

Various bat species often occupy the same habitats. Cohabitation should induce different preferences in spatial or trophic components of the bat ecological niche to reduce their competition. This determines the differences in the trematode fauna of spp.
