摘要：
In this study we tested the hypothesis that the European hareLepus europeaeus avoids areas around nests of the ravenCorvus corax built on electricity pylons in an intensively used farmland. Hare counts were conducted in spring 1999 and 2000 in areas of 1000 m length and 200 m width along 47 transect lines starting from pylons with raven nests. Likewise, 47 control areas along transect lines, which started from pylons without any nests were studied. The two types of transects did not differ with respect to the number of recorded hares. The main factor influencing hare occurrence in farmland was found to be habitat diversity.
