ALTAY-SAYAN ECOREGION LEPIDOPTERA POPULATION: SPACIOUS AND TYPOLOGICAL STRUCTURE PART II. ORGANIZATION AND ENVIRONMENTAL FACTORS
Carried out for many years in Altai-Sayan mountainous region registrations of Lepidoptera have proved that spacious heterogeneity of the population is primarily determined by the area and moistening. Regional variations depend to a considerable less extent on the area altitude, flood-lands and to much less extent on slope steepness and bushing out of the territory. The article analises changes of density of population, of species diversity, of core species among the belts of five regions: south-eastern Altai, Tyva, northwestern Mongolia, north-western China, Khakassia and the south of Krasnoyarsky krai. Classifications of Alati-Sayan ecoregion Lepidoptera population and Lepidoptera species in accordance with distribution similarity have been made.
