Methods

Obviously that for a productive analysis of this problem including methodological objectives an important requirement is a good choice of the model object. From the standpoint of the work carried out in this approach is adequate for the task is recognized as an example of the dynamics of small mammal communities of Verkhnyaya Angara basin - one of the series of depressions of the northeastern flank of the Baikal rift zone. By biogeographic detachment of the Institute of Geography of the SB RAS for four field seasons were obtained information about the structure of the population of the main types of basin habitats seasonal and inter-annual population dynamics structure and characteristics of population reproduction etc. The works were carried out in each of their four years of research from April-May to September. To capture small mammals used traditional trapping grooves (25 m long with two cones). There were worked out 30 thousand of trap-nights. For comparison the materials obtained in different years using data accounts for the periods from 20 July to 20 August which are characterized by the highest representation. During 4 years of studies have examined more than 90 habitats covering all altitudinal belts and the prevailing types of plant communities. The total volume of the studied animals is almost 27 thousand copies of 27 species. Analyzed publications covering the results of studies of other zoological expeditions in this area [20 78 103; and etc.]. Zoogeographical analysis of the theriofauna of the region held by V.F. Lyamkin [58].
