The research on spatial dynamics of housing species populations using geographic information system

Бесплатный доступ

To study spatial functioning of populations in natural con- ditions, various traditional methods are used, which reflect the overall picture, but do not reflect (graphic image) of the dy- namics of the state of populations in time. The adaptation of long-term field data to geographic information system (GIS) to explore spatial distribution of populations on the territory of Turukhansk district of the reserve ‘Tsentralnosibirsky’ using the method of classification of habitats allowed us to obtain General map of habitats’ classification and to analyze spatial dynamics of the density of genus Clethrionomys, Microtus, and Sicista genus Martes in conservation area. According to the records in protected area during 24 years, the average density of sable per 1000 hectares ranged from 1.8 to 3.2 species. The greatest density of genus Martes in autumn was noted in different aged cedars. The distribution of small mammals in habitats is as follows. Overwintered adult species are found in favorable habitats (coniferous taiga), and the young are found in less conducive habitats (deforestation, floodplain overgrown with willow)...
