Краткое описание

Limnological peculiarities of the ecosystems of four lakes of glacial origin, including the lakes Pisey-ty, Vozey-ty, Yevsya-ty, and Syattey-ty (Komi Republic, Russia), were studied. The water of these lakes belongs to the hydrocarbonate class of the calcium group of the first type with a low level of mineralization. Lake Syattey-ty is characterized by a high content of iron in water, whereas Lake Yevsya-ty is characterized by a high content of silicon. Production of littoral organisms was higher than that of pelagic organisms. The difference between zooplankton and zoobenthos is statistically plausible with P = 0.1−0.01. The composition of zooplankton organisms occurring in the littoral zone was similar to that of the pelagic zone. Zoobenthos in these two zones was characterized by distinctions. The total production of zooplankton and zoobenthos in these lakes was distinguished by the following values: 4.64 t/ha - in Lake Pisey-ty, 1.08 t/ha - in Lake Yevsya-ty, 0.45 t/ha - in Lake Syattey-ty, 0.39 t/ha - in Lake Vozey-ty. The proportion of littoral organisms in the total production of the lakes was as follows: 19.6% - in Lake Pisey-ty, 5.5% - in Lake Yevsya-ty, 70.8% in Lake Syattey-ty, and 14.5% - in Lake Vozey-ty.
