Physiological and biochemical responses to cold and drought in the rock-dwelling pulmonate snail, Chondrina avenacea

Popis výsledku v původním jazyce

The pulmonate snail Chondrina avenacea lives on exposed rock walls where it experiences drastic daily and seasonal fluctuations of abiotic conditions and food availability. We found that tolerance to dry conditions was maintained at a very high level throughout the year and was mainly based on the snails? ability to promptly enter into estivation (quiescence) whenever they experienced drying out of their environment. The metabolic suppression probably included periods of tissue hypoxia and anaerobism asindicated by accumulation of typical end products of anaerobic metabolism: lactate, alanine and succinate. The seasonally highest levels of supercooling capacity, and the highest tolerance to subzero temperatures, were tightly linked to hibernation (diapause). Hibernating snails did not survive freezing of their body fluids and instead relied on supercooling strategy which allowed them to survive when air temperatures dropped to as low as -21?C.
