Abstract:

The article examines quantitative regularities in the distribution of biotic taxa in Yamalo-Nenets autonomous okrug. Their close relationship with the climate is demonstrated with the heat index (the sum of positive temperatures), which controls the flow of heat from the atmosphere to the Earth surface. We created schematic maps of isolines of the main characteristics of the climate in YNAO. The character of distribution of biota taxa is described, concerning plants (species, genera, families, orders, classes) and animals (species, genera, families, orders) by geographic zones and sub-zones of the studied region. We consider features, graphs and formulas of the geographical (climatic) and hierarchical dependence of the number of biotic taxa of different ranks, and assess their reliability. The ratio of taxa of animals and plants on the territory of Yamal is analyzed. It is concluded that the unity and interdependence of the existence of plants and animals, their total dependence on the climate and, thus, the relation of number of geni, species, families (and orders — when speaking of animals) to the number of species is constant and does not depend on climate.
