The Impact of Experimental Hypoxia and Subsequent Normoxia on the Content of Some Ions and Markers of Physiological Stress-adaptation in Gastropod Species Lymnaea stagnalis

Abstract

The purpose of this study was to evaluate the influence of hypoxia and subsequent normoxiaon the maintenance of respiratory pigment hemocyanin, total protein, lactate and some ions (Na +, K +, Ca2+, NH4+, Mg2+) in the mantle liquid in palaearctic gastropod species Lymnaea stagnalis. It was shown that short-term experimental hypoxia leads to the activation of the physiological mechanisms of stress adaptation in widespread Palaearctic eurybiotic gastropod species and does not lead to the activation of the stress-resistance mechanisms on the biochemical and molecular levels.
