For the entire territory of West Siberia, including its plain and mountainous parts, two maps were constructed for populations of amphibians together with reptiles, and of birds. Communities of these classes of vertebrates differ from one another in their spatial differentiation. The differences are demonstrated for the plain and mountainous territories(More)
The area under study covered the West Siberian Plain from the Urals to the Yenisei River and the same band to the southern borders of the former Soviet Union in 1991, including a part of the Altai-Sayan mountain country, Kazakhstan, Uzbekistan, Turkmenistan, and the whole of Kyrgyzstan and Tajikistan. The results of ornithogeographic surveys carried out on(More)
The proposed classification system reflects the difference between the three population systems: unbuilt land, built-up land, and aquatic–semiaquatic communities. Two superorder groups—north and median—further divided into types were recognized in each of the systems. Most types are divided into subtypes, classes, and subclasses (and sometimes genera of the(More)
Cluster analysis and plotting based on censuses of ant nests and existence energy of mammals were used to classify their communities and species by similarity of distribution. As a result, eight maps were drawn up, with characteristics of the areas populated by the animal groups analyzed. Changes of population density and species abundance with altitude(More)
The results of bird route surveys over the territory of the Central Altai during the summer seasons in 1968–2001 were analyzed. Hierarchic classifications of species by the similarities of residence and distribution were compiled on the basis of a multivariate factor analysis. The basic environmental factors that determine the non-uniformity of bird(More)
