Collembola distribution at gradient of soil moisture of the middle taiga pine forests (on the example of reserve «Belyi»)

Composition, structure and density of collembolan of organic horizons of alphehumus soils, formed at gradient of soil moisture of the middle taiga pine forests, are researched. There is shown connection between collembolan species diversity and community density and the character of soil-vegetative cover and weather conditions (air temperature, precipitations). Changes of number of dominants, correlation between different groups of hygropreferences and vital forms of collembolan at gradient of soil moisture of pine forests are revealed.
