我们测定了芬兰南部北方蝙蝠Eptesicus nilssonii(Keyserling et Blasius，1839)、Brandt‘s bat Myotis brandtii(Eversmann，1845)、胡须蝙蝠(Kuhl，1819)、Daubenton’s bat Myotis daubentonii(Kuhl，1819)和棕色长耳蝙蝠Plecotus aurtes(Linneeus，1758)的觅食栖息地。在这些物种中，我们同时比较了它们觅食生境的多样性、线性特征偏好和蝙蝠的觅食倾向。尼尔逊石斑鱼是最具机会性的，在广泛的生境中觅食。达本顿鼠鼠(94%)主要在水生生境觅食，而蝙蝠则是。Brandtii/mysta inus(89%)和P.奥里乌斯(66%)主要在森林栖息地觅食。觅食栖息地的多样性使用了再见。尼尔森和P。极值高于正常值。Brandtii/mysta inus和M.多本顿奶酪。尼尔森和P.极光主要是独自觅食或少量觅食。Brandtii/Mysta促使它们成群结队地聚集在同一栖息地觅食。一半的人。尼尔森和46%的股份。Daubentonii取食线形特征，而其他物种没有如此程度地使用线形特征。需要管理和保护觅食栖息地，特别是形式。Brandtii/mysta inus和M.Daubentonii，这是更专业的谢谢。Nilssonii和P.auratus。
We determined the foraging habitats of the northern batEptesicus nilssonii(Keyserling et Blasius, 1839), Brandt’s batMyotis brandtii(Eversmann, 1845), whiskered batMyotis mystacinus(Kuhl, 1819), Daubenton’s batMyotis daubentonii(Kuhl, 1819) and brown long-eared batPlecotus auritus(Linnaeus, 1758) in southern Finland. Among these species, we compared the diversities of foraging habitats, linear feature preference and the bats’ tendencies to forage simultaneously.Eptesicus nilssoniiwas the most opportunistic, foraging in a wide range of habitats.Myotis daubentonii(94%) foraged mainly on water habitats, whileM. brandtii/mystacinus(89%) andP. auritus(66%) foraged mainly in forest habitats. The diversities of foraging habitats used byE. nilssoniiandP. aurituswere higher than those ofM. brandtii/mystacinusandM. daubentonii. Both E.nilssoniiandP. auritusforaged mostly alone or in small numbers, whileM. brandtii/mystacinustended to gather in large numbers to forage in the same habitat. Half ofE. nilssoniiand 46% ofM. daubentoniiforaged over linear features, while other species did not use linear features to such an extent. Management and conservation of foraging habitats are needed especially forM. brandtii/mystacinusandM. daubentonii, which are more specialized thanE. nilssonii and P. auritus.
