Fauna and ekology ground beetles (Coleoptera, Carabidae) in Southern Yakutia

Due to its climate and location Yakutia presents an asset in the point of investigating its ground beetle fauna. The research into the ecology and population of carabid species inhabiting this region has received much attention in the literature [1-6]. The research described was conducted in Southern Yakutia near Aldan Plateau. The area has a severely continental climate with a large annual and daily temperature range. Its dominant soil type is identified as acid mountain taiga cryogenic type, and the features of local flora enable us to infer that Southern Yakutia belongs to the middle taiga subzone. Its land cover is formed mainly by larch and pine forests with the shrub layer, complemented by cembretum, lichen and moss [7].

In this paper we report on the material S. V. Rogatnykh collected near Tommot Village and the Verkhnyaya Amga River in the years of 2008 - 2010. Most specimens were collected using the Barber’s pitfall traps and also by examining objects found on the soil. Collecting was chiefly performed in the following biotope types: (I) in an uncultivated agrocenosis in Tommot Village (the year of 2008), (II) in a mixed deciduous forest on the western outskirts of Tommot Village (the year of 2009) and (III) on the pebble bank of the Verkhnyaya Amga River (years of 2009 and 2010). All received data are listed in table 1.

The total amount of specimens collected is 1113. It comprises 54 species from 14 genera that constite 13 tribes. The highest number of species (33) and species diversity (61 %) was ascertained in the Amga River. The most numerous genera here are Carabus (7 species), Bembidion and Agonum (5 species in each). The rest are represented by only 1 or 3 species with. Carabus canaliculatus, Poecilus fortipes and Pterostichus procax dominating. In the agrocenosis, the most numerous genera are Amara (7 species), Carabus and Pterostichus (5 species in each). The rest are represented by only 1 or 3 species with Nebria nivalis, Pterostichus matveichuki and Carabus macleayi dominating. The number of specimens collected here is 199 specimens belonging to 30 species. The deciduous forest is characterized by the decrease of species diversity.
