要約

Paper deals with adaptive reactions of Gammaridae populations (Pontogammarus robustoides (Sars, 1894), Echinogammarus ischnus (Stebbing, 1899), Dikerogammarus villosus (Sowinsky, 1894), Dikerogammarus haemobaphes (Eichwald, 1841)) in the coastal shallow zone of the Kyiv reservoir at different water temperature. Animals avoid sections with water temperature above 28°C. The prolong impact of critical temperature result in mass migration to the sections with more comfortable conditions (deeper sections, trees' roots in the splash zone), in decrease of the reproduction intensity or even stop of reproduction. At gammarids migration to the deeper sections to the mollusks' cenoses (depth > 0.8 m) dominated species of the gen. Dikerogammarus (D. villosus, D. haemobaphes), at this prevailed specimens of the middle and elder size-age groups, whereas within the trees' roots in the splash zone gammarids are distributed unevenly, with alternative domination of P. robustoides, D. villosus and E. ischnus. The long-term effect of the thermal abnormalities consists in significant annual fluctuations of gammarids numbers in the shallow zone of the Kyiv reservoir.
