Long-term dynamics of birds and ground beetles population density in catena of barguzinskiy ridge (Northern Pribaikalye)

Бесплатный доступ

In article some results of research the numerosity long-term dynamics of two faunistic complexes - ground beetles and birds in the conditions of the Barguzinsky ridge with use of catena method are reflected. The gen-eral long-term decrease in population density of birds and ground beetles in eluvial, top and bottom transit de-partments and increase - in catena accumulative department is established. The mechanism of numerosity dy-namics of birds and ground beetles is essentially distinguished, correlation of abundance change between these two groups is absent. Population strategy of ground beetles consists in the adaptation to environment condi-tions in a habitat, birds - in an annual choice of optimum habitats.
