Ключевые слова (''Своб.индексиров.''): carassius auratus--cyanobacteria--gut passage
Аннотация: Growth and potential photosynthetic activity of phytoplankton passed through intestine of crucian carp (Carassius auratus) from a small Siberian reservoir were compared with those of phytoplankton taken the directly from the reservoir. The dominant phytoplankton species in the reservoir, Microcystis aeruginosa, showed a significant increase of growth after the passage. Subdominant Planktothrix agardhii also showed an increase in growth rate, while subdominants Anabaena flos-aquae and Aphanizomenon flos-aquae were not stimulated by the gut passage.

Ключевые слова (''Своб.индексиров.''): epibiontic microalgae--cyclops vicinus--daphnia longispina--mutualism--algal bloom
Аннотация: The possibility of symbiotic, mutualistic (++) interrelations between epibiontic microalgae (Characidiopsis ellipsoidea, Colacium vesiculosum) and cyclopoids (Cyclops vicinus, Mesocyclops leukarti) in the Bugach recreational reservoir with a bloom of cyanobacteria is demonstrated. Overgrown cyclopoids, compared to those free from microalgae, have advantages in oxygen supply, which may be insufficient in the period of intensive algal bloom. Calculations have shown that oxygen requirements of cyclopoids may be fully satisfied due to C. vesiculosum photosynthetic activity in the dysphotic zone if the density of overgrowth exceeds 1000 algal cells per individual. There is no significant correlation between the natural mortality of crustaceans and the indices of their overgrowth by microalgae.

Ключевые слова (''Своб.индексиров.''): characidiopsis ellipsoidea--g. colacium--cyclops vicinus--daphnia longispina--eutrophic reservoir--phototrophic epibionts
Аннотация: Seasonality of burden and prevalence of phototrophic (microalgal) epibionts Characidiopsis ellipsoidea, Colacium vesiculosum and Colacium sp. on dominating crustacean zooplankton (Daphnia longispina, Cyclops vicinus and Mesocyclops leuckarti) were studied in a small reservoir Bugach with cyanobacterial bloom. The correlations between the seasonal dynamics of prevalence and the dynamics of others biotic and abiotic factors were calculated. The conclusions were as follows. The substrate species, that determined the development of the epibionts on the three studied crustacean zooplankton, was Daphnia longispina (Cladocera). Despite intensive epibiotic infestation of crustacean zooplankton, epibionts did not appear to have caused non-consumptive mortality of the crustacean zooplankton. But they could have contributed to the Daphnia summer decline by increasing mortality due to its consumption by planktivorous fishes. The phototropic epibionts may successfully coexist with cyanobacterial bloom. The possible role of the epibionts in changing nutrient fluxes in pelagic food web is discussed.
