Changes in the structure of ground beetle communities indicate environmental stability or instability influenced by, e.g., urbanization, agriculture, and forestry. It can affect flight capability and ellipsoid biovolume (EV) of ground beetles. Therefore, we analyzed ground beetles in various habitats. In the course of the period from 2015 to 2017, we recorded in pitfall traps 2379 individuals (1030 males and 1349 females) belonging to 52 species at six localities (two rural, two suburban, two urban). We observed the decrease in the average EV value and morphometric characters (length, height, and width of the body) of ground beetles in the direction of the rural–suburban–urban gradient. Our results also suggest a decrease in EV of apterous and brachypterous species and an increase in macropterous species in the urban and suburban landscapes near agricultural fields. The increasing EV of apterous and brachypterous species and the decreasing of macropterous species was observed in rural landscape conditions with not continuous cover forestry and partial forest management. The creation of habitat fragments in urbanized conditions is key to maintaining the average EV in apterous and brachypterous species in urban and suburban landscapes. |
