Structure and population dynamics of pterostichus spp. Beetles (col. Carabidae) in three types of wetland

Abstract

This study presents research on communities of Pterostichus spp. beetles found in 2001 and 2003 in three types of wetland: elm and ash riparian forest (RF), poplar monoculture (P) and extensively managed meadow (M). All sample plots were located near the city of Bydgoszcz (53o, 9'N18oE) on the Vistula River floodplain. During both years, 11 species of genus Pterostichus spp. were found. In 2001, from all sample plots 886 beetles were collected; in 2003, 5 963. In both years, most specimens came from plot RF (636 in 2001 and 3 544 in 2003). From plot P, 1 862 specimens of Pterostichus spp. beetles were collected and from plot M, 807 specimens. No statistically significant influences of the marshland habitat type and year of research on communities of Pterostichus spp. beetles were revealed.
