Opis:
Baikal Lake fish: stone sculpin (Paracottus knerii), yellowfin (Cottocomephorus grewigkii) and perch (Perca fluviatilis) were exposed for 14 days to phenol (6mg˖L-1). The reaction of blood cells in all studied species had a similar character, whilst, also revealing distinctions. Fast activation of immune processes was found in the pelagic yellowfin. These changes were slower at the coastal stone sculpin. Quantitative changes of blood cells were minor in the coastal nonendemic perch. After four days of exposure, the cells of fish showed signs of destructive processes: strong vacuolization of cytoplasm and partial destruction of the cell membrane. In the cell nucleus the chromatin was condensed, the perinuclear space had expanded and the nuclear membrane had been partly destroyed. In another experiment, stone sculpin and perch were first exposed to phenol for 30 days and then they were kept for another 30 days in water without phenol. In the kidneys and spleen of stone sculpin the processes of lymphopoiesis were observed, whereas in perch the processes of lymphopoiesis and myelopoiesis occurred.

Opis:
Exposure to phenol causes ultrastructural disorders in supporting and receptor cells in the peripheral segment of the olfactory organ of yellowfin (Cottocomephorus grewingkii) and in cells in peripheral blood of stone sculpins (Paracottus knerii), yellowfin and perch (Perca fluviatilis). Identical responses to phenol exposure in the blood cells were observed in endemic Lake Baikal fish and in nonendemic fish. Differences were found only in the rate and intensity of the recovery response. Fast activation of immune processes were found in the coastal nonendemic perch, but they were slow in the stone sculpin, a coastal endemic species.

Opis:
Coregonid fishes (coregonids) (Salmonidae, Coregoninae) of Siberia show immense morphological and ecological variability, what is reflected in their complex interspecific and intraspecific structure: i.e. occurrence of numerous species, forms and endemic species. Studies of the coregonids of Siberia is crucially important for understanding of their origin, taxonomy and evolution. We have analysed electrophoretically some 13 enzyme systems from over 20 samples of East-Siberian coregonids. This paper was intended as an introduction to a number of primary papers that are planned that will describe the biological and genetic characteristics of studied populations.

Opis:
Allozyme structure of the tick population Ixodes persulcatus coded by nine enzyme gene loci has been studied using two subsamples of ticks from Irkutsk suburban areas. Nine loci out of fourteen were polymorphic in ticks of Baikal highway population, whereas five loci were polymorphic in tics sampled from Goloustnoye highway. High level of intra-population heterogeneity of ticks has been revealed. No distinction between two populations from different nidi of infection has been recorded. It was probably due to the high rate of gene migration between the studied populations and to their high genetic similarity.
