Abstract

This paper demonstrates that the species composition of the surface-active beetles (Coleoptera: Carabidae, Staphylinidae, Elateridae) in the landscape site is determined by its local crop. The hygrophilous species are most common in areas with dense vegetation. Assemblages of the epigeic beetles in fields of different crops and adjacent habitats (field margins overgrown with shrubs and forbs) are separated from each other. Beetles associated with a leaf litter layer dominate on the field margins, while rarely occurring in the fields. The populations of the surface-active beetles in perennial grass fields and field margins have the highest species richness.

Highlights

Many species of beetles (Coleoptera), both zoophages and phytophages, occur in boreal agricultural landscapes, mainly on the soil surface, the patterns of their distribution remain understudied
80 Carabidae species, 120 Staphylinidae and 24 Elateridae species were observed in the Menkovo Research Station (MRS) agricultural landscapes in the Leningrad Region between 2004–2016
There are few species common in the field can occur in the field margins: ground beetles Poecilus cupreus (L.), P. versicolor (Sturm), and Harpalus rufipes (DeGeer), rove beetles Dinaraea angustula (Gyll.), Mocyta fungi (Grav.) and Aloconota gregaria (Er.), click beetles Agriotes obscurus (L.), and A. lineatus (L.)

Summary

Introduction

Many species of beetles (Coleoptera), both zoophages and phytophages, occur in boreal agricultural landscapes, mainly on the soil surface, the patterns of their distribution remain understudied. It is only known that the vegetation cover affects the distribution of assemblages of the epigeic (soil-surface) beetles [1,2,3,4,5]. This study aims to fill this gap determining the structure, species richness, and abundance of the epigeic beetles in the different fields and adjacent semi-natural habitats of Northwestern Russia
