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.

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.
