Annotation:
An ecological and faunistic analysis of helminths in the Charadrii of Baikal Siberia was carried out. Majority of the material we collected on Lake Baikal. It has been established a systematic diversity of helminthofauna, which consists of 88 species from 4 classes and 17 families. In terms of species, cestodes predominate (40.9%), trematodes account for just over one third (34.1%), nematodes amount to one fifth (23.7%), and there are very few acanthocephalans (1.1%).
Theratioofdifferentclassesofparasitesisnoticeablydifferentinsubfamiliesofcharadriiformes. In plovers, sandpipers and Calidris cestodes prevailed, in lapwings, turnstones, pike smelts, Tringa and Haliplidae — trematodes. The greatest diversity of parasite species was found in little stints, wood sandpipers, and tereks.
A wide variety of hosts among Charadrii had cestodes Aploparaksis sachalinensis, Anomo- taenia tringae, Aploparaksis crassirostris, Anomotaenia citrus, trematodes Plagiorchis nanus, Cyclocoelum mutabile, Leucochloridium actitis, Echinoparyphium politum, Plagiorchis vitellatus, nematodes Tetrameres dubia Porrocaecum semiteres. We have revealed many helminths specific for charadriiformes (Anomotaenia — A. citrus, A. globulus, A. tringae, etc., Pseudanomotaenia paramicrorhyncha, Trichocephaloides megalocephala, Aploparaksis sachalinensis, etc.).
Helminthofauna in different subfamilies of Charadriiformes has relatively small similarity, which is explained by differences in feeding habits, foraging behavior, and habitual area of different species.
