MAIN CLIMATIC PREDICTORS OF SPATIAL DISTRIBUTION OF SAPROXYLIC INSECTS IN FOREST ECOSYSTEMS OF NORTHEAST ASIA

Based on our own field data and using modeling of potential habitats (in the MaxEnt program), the biotopic distribution of Callipogon (Eoxenus) relictus Semenov 1899 in Northeast Asia was assessed and climatic predictors of its spatial distribution were determined. The constructed cartographic model of the potential range of C. relictus demonstrates a high probability of the species inhabiting the mid-mountain regions of the southern Russian Far East, the provinces of Northeast China and the Korean Peninsula. Field data is also show a large-scale confinement of the species to intact broad-leaved and coniferous-broad-leaved forests of Northeast Asia. The most significant predictors in forecasting the range of the beetle were the altitude above sea level, the amount of precipitation in the driest quarter of the year and temperature factors.
