[Degradation succession of heterotrophic flagellate communities in microcosms]
Abstract:
Degradation succession of heterotrophic flagellate communities was studied in samples of detritus and water from a small swamped lake in the environs of the settlement Borok, Yaroslavl province. Three stages of succession with different species composition of the heterotrophic flagellate community were clearly recognized. Cumulative properties of the community change with time. Maximum species richness, diversity, and abundance were observed on the fourth day of succession; their values gradually decreased later. The trophic and taxonomic community structure was most diverse at the earlier stages of succession. Primordial food (bacteria) concentration affects only the size of peak community properties, but has no influence on the pattern of succession changes. The influence of predators considerably reduced heterotrophic flagellate abundance and can shift the time of the stage with maximum species diversity in the course of succession.
