We collected carabid beetles (Coleoptera: Carabidae) with identical sampling effort in the main habitat types on three islands (area 29-93 ha, distance to the Aland mainland 4-20 km) in the Baltic Sea. The vegetation area on the islands decreases with increasing distance from the mainland. As the mainland reference we use samples taken from the Aland mainland (area about 900 km2). There was pronounced variation in the occurrence of individual carabid species be tween the islands and the… CONTINUE READING
