Název v původním jazyce

Life history response of Daphnia galeata to heterogeneous conditions within a reservoir as determined in a cross-designed laboratory experiment

Popis výsledku v původním jazyce

Growth and reproduction were studied in the laboratory in a cross-designed experimental set-up in four Daphnia galeata subpopulations collected from different locations in a reservoir. The results revealed significant effects of the two factors manipulated ? source of water used for cultures and Daphnia subpopulation ? on the life history characteristics of growth and reproduction. The water from the upstream part of the reservoir was the most favourable culture medium for all characteristics of the Daphnia groups studied (the largest primiparae, clutches and eggs, the shortest postembryonic development time and filtering setae). The poorest performances were recorded in the downstream, epilimnetic and metalimnetic waters. The Daphnia subpopulation originating from the hypolimnion had the smallest primiparae, the largest clutches, the smallest eggs and the shortest postembryonic development, whereas the opposite was found in animals from the epilmnion.
