[Seasonal dynamics of the structure of component communities of parasites in the young minnow Phoxinus phoxinus (L.)]
Abstract:
Component communities of parasites of Phoxinus phoxinus from the Chovju River near Syktyvkar City (Komi Republic) are investigated in seasonal aspect. Material for the study has been collected in May-September 2000 from 90 host specimens of ages 0+-1+. Calculations of diversity indices and other coefficients have been made by two ways -- for metazoan parasites only and for whole parasite community including protozoan species. In both these cases three states of the community have been established, 1) forming community in May-June, 2) completely formed community in the end of June-July, 3) disintegrating community in August, 4) forming community in September. Seasonal dynamics of the component communities in young minnow thus found to be different from that in adult fish hosts.
