Natural zonality in the distribution of arthropods, birds, and vascular plants in the area of the Lower Ob region and Yamal Peninsula

详细

This paper is devoted to an analysis of the pattern of zonal distribution of mesofaunal arthropods, birds, and vascular plants in the area from northern taiga forests to arctic tunrdas of the Yamal Peninsula by the gradient of summer air temperatures. The latitudinal dynamics of northern ecosystems determines differences in the number of plant species that have a direct effect on the species richness and abundance of invertebrates and an indirect one through invertebrates on the same indices of birds. Breaks in continuity marking the natural boundaries where the components of arctic communities become boreal have been found in the changes of species diversity.
