We compared the thermal aggregation properties of two isoforms of the isolated myosin head (myosin subfragment 1, S1) containing different "essential" (or "alkali") light chains, A1 or A2. Temperature dependencies for the aggregation of these two S1 isoforms, as measured by the increase in turbidity, were compared with the temperature dependencies of their(More)
The spatial distribution of the terrestrial invertebrate population of the West Siberian Plain is analyzed at the level of large functional groups (soil nematodes, annelids, microarthropods, mesoarthropods, snails, grass layer arthropods). Their air-dry biomass and roles in local ecosystems are estimated. The invertebrate population was classified in two(More)
For the purpose of zoning on the basis of theriofauna, Northern Eurasia was considered within the boundaries of the Soviet Union in 1991 and was divided into 245 mapping units. Mapping units were marked on the World Vegetation Map at a scale of 1: 2000000. Each mapping unit occupied a territory within the limits of a natural subzone with a latitudinal(More)
Similarity coefficients were quantified for the ecosystems of the West Siberian Plain on the basis of the air-dry masses of dominant and subdominant plant species in five life forms (mosses, lichens, grasses, dwarf shrubs, shrubs, and trees) indicated in the formation ranges of the phytogeographic map of the West Siberian Plain. The resultant matrix was(More)
For the purpose of zoning on the basis of fauna of terrestrial vertebrates, Northern Eurasia was considered within the boundaries of the Soviet Union in 1991 and divided into 245 mapping units. Mapping units were marked on the World Vegetation Map at a scale of 1: 20000000 in such a way that each mapping unit occupied a territory within the limits of a(More)
