[Ecology of Gammarus lacustris sars (Crustacea: Amphipoda) in Transbaikalian water bodies].

The data on Gammarus lacustris Sars, 1863 ecology in Transbaikalian water bodies was integrated by the example of Lakes Khalanda, Bain-Tsagan, Arakhlei, Zun-Torei, and Bain-Bulak. The impact of the major environmental factor on the pattern of G. lacustris spatial distribution, linear size, growth rate, time of reaching sexual maturity, and number of reproduced generations was shown. The role of G. lacustris in the ecosystem of studied water bodies was evaluated and the adaptive significance of the revealed life strategies was considered.
