Qualitative and quantitative structures of benthic macro-invertebrates, macrophytes, zooplankton, as well as ichthyofauna and fish parasites of the shallow areas of Small Sevan that flooded as a result of an increase in the lake’s water level are analyzed. It is shown that the most appropriate conditions for the development of hydrobionts were found in the area that was flooded earlier and is dire ...

- Abstract:
- ... The influence of infection with trematode metacercariae on some physiological and biochemical characteristics has been studied in the underyearlings of roach. The parameters that were studied are found to depend on the parasite localization. The body length and weight values of infected underyearlings with muscular localization of metacercariae are lower than in uninfected fish and the glycogen co ...

A total of 290 species and varieties of Bacillariophyta including 32 that were new for the flora of Karelia and 18 that were new for the flora of Russia, have been recorded in phytoplankton in nine rivers of the White Sea basin. The genera Aulacoseira, Pinnularia, Eunotia, and Navicula s. l. are the richest in taxonomy. The maximum species diversity was recorded in the Suma (73), Kolezhma (91), an ...

- Abstract:

The basic patterns of the spatial structure of phytoplankton in large oligotrophic rivers of northeastern Siberia were determined using principle component analysis (PCA), factor analysis, and cluster analysis. It was found that in extreme conditions of oligotrophic subarctic rivers the formation of the spatial structure of the phytoplankton generally occurs under the influence of climate, rather ...

- Abstract:
- ... The species boundaries and biogeography of two closely related diatom species, Nitzschia longissima (Bréb.) Grunow and N. rectilonga Takano, are described. Based on the structure and morphological features of frustule valves, a reliable distance between these two species has been determined. It is shown that there is a reproductive barrier between the two species. The distribution of N. longissima ...
