摘要
笔者研究了贵州省安龙县5种蝙蝠:蹄蝠科蹄蝠属的大蹄蝠、黄大蹄蝠、中蹄蝠和三叶蹄蝠属的三叶蹄蝠,以及菊头蝠科菊头蝠属的皮氏菊头蝠的生态形态特征与猎物选择的关系。通过对5种食虫蝙蝠的生态形态特征参数的测量,发现体型较大、飞行较快的大蹄蝠、黄大蹄蝠主要捕食体型较大的鞘翅目、鳞翅目昆虫;体型较小、飞行较慢的三叶蹄蝠则以小型鳞翅目和双翅目昆虫为食;体型居中的中蹄蝠和皮氏菊头蝠不仅选择中等体型昆虫,而且与其余3种蹄蝠的食性部分重叠,这与捕食者体型与猎物体型相一致的生态规律相符。
In this article, the relationships between eco-morphology and prey selection of four hipposiderid bats and one rhinolophid bat were reported. This study was carried out at Dushan Village of Anlong County in Guizhou Province. The larger bats, Hipposideros armiger and Hipposideros pratti, selected the larger insects. The smallest bat in this study, Aselliscus stoliczkanus, selected the pint-sized insects. The prey selection of Hipposideros larvatus is between the two patterns mentioned above.
