The content of free amino acids in the tissues of freshwater leeches Haemopis sanguisuga (L., 1758) of the aquatic ecosystems of different climatic zones and different seasons (spring, summer, autumn) were studied. Found that dwelling leeches in adverse weather conditions is accompanied by an intensification of amino acid metabolism and consistently high level pattern of essential amino acids in the tissues. It is shown that the greatest influence on the amino acid exchange leeches H. sanguisuga has autumn drop in temperature. In the tissues of leeches, going in winter hibernation, there is an amino acid imbalance, which indicates a high ecological plasticity of their metabolic processes. Found that an increase in the total concentration of free amino acids in the tissues is an adaptive mechanism leeches H. sanguisuga to adverse environmental factors.
