Abstract
The goal of the investigation is comparative evaluation of the protein spectra and their changes under stress in several species of fresh-water amphipoda. Endemic species from Lake Baikal and Palearctic species differing by their adaptive ability were studied. Polymorphism of the protein spectra not only between systematically dissimilar but also between closely related species was revealed. Polymorphism of the protein spectra was observed in the differently aged stages of two Baikalina amphipod species. The effect of temperature stress on the protein spectra was estimated. It was shown that the temperature stress affects the content and synthesis of some proteins which have inter-species and age differences.
