Comparative study of thermoresistances' cellular mechanisms in representatives of the Gammarus lacustris Sars populations inhabiting saline Lake Shira (Republic of Khakassia) and a fresh water body in the Cis-Baikal region.

摘要

Cosmopolit species display a wide ecological valence, allowing them to live under most diverse eco logical conditions. Correspondingly, representatives of individual populations living in biotopes with different and even contrasting conditions can differ in resis tance to specific stress factors [1]. The mechanisms underlying the variation in stress adaptation of a species are yet insufficiently clear. It is known that the resistance to stress factors is based on a set of nonspecific cellular and molecular reactions [2]. Presumably, the differences in their activation are the factors that determine the degree of stress resistance.
