Patterns of distribution of phytophagous insects in grass ecosystems of the holarctic

摘要

The main methodological approaches used to reveal the patterns of distribution of insects are discussed. The location of ranges and centers of diversity of the phytophagous insects, particularly Orthoptera, is characterized in the regions of distribution of the grass ecosystems in the Holarctic. The general picture of distribution of population groups, biomass, and communities of Orthoptera along the zonal and continental gradients is described.
