问题：猪笼草如何促进互惠蝙蝠的栖息？假设：投手有适应性，以匹配的形状和身体大小的小羊毛蝙蝠。生物：猪笼草（Nepenthes hemsleyana），其近亲猪笼草（N. rafflesiana和毛蝠Kerivoula hardwickii。实地考察地点：婆罗洲岛文莱达鲁萨兰国西部的泥炭沼泽和石南森林。方法：对N. hemsleyana可能有助于蝙蝠栖息，并将它们与N.没有蝙蝠光顾的植物。我们比较了投手的大小和特点与栖息蝙蝠的身体大小。结论：正如预测的那样，空中投手与蝙蝠的体型相匹配，并且比近亲投手的消化液水平低。因此，密切相关的物种之间的小形态差异造成快速饮食生态位分歧。
Question: How does the pitcher plant Nepenthes hemsleyana facilitate roosting of mutualistic bats? Hypothesis: Pitchers have adaptations that match the shape and body size of small woolly bats. Organisms: The pitcher plant Nepenthes hemsleyana, its close relative N. rafflesiana, and the woolly bat Kerivoula hardwickii. Field sites: Peat swamps and heath forests in western Brunei Darussalam on the island of Borneo. Methods: We measured various morphological traits of N. hemsleyana that might facilitate bat roosting and compared them to pitchers of N. rafflesiana that is not visited by bats. We compared the size and characteristics of the pitchers with body sizes of roosting bats. Conclusions: As predicted, aerial pitchers matched the body size of bats and had lower digestive fluid levels than pitchers of a close relative. Thus, small morphological differences between closely related species have caused rapid dietary niche divergence.
