Data from: Flower-visiting bat species contribute unequally toward agricultural pollination ecosystem services in southern Thailand

The large majority of angiosperm species depend on animals for pollination, including many agricultural crops, and plant-pollinator interactions have been extensively studied. However, not all floral visitors actually transfer pollen, and efforts to distinguish true pollinators from mere visitors are particularly scarce among the bat pollination literature. To determine whether Old World bat species are equally effective pollinators in mixed-agricultural areas of southern Thailand, we examined six night-blooming plant taxa and quantified pollinator importance (PI) of seven common nectarivorous bat species. PI was calculated as the product of nightly bat visitation rate (obtained from mist-netting data) and pollen transfer efficiency (estimated from bat pollen loads). We found that PI varied by both bat species and plant species. In general, the nectar-specialist bat species were more important pollinators, yet their order of importance differed across our focal plant species. In addition, PI was dictated more by pollen transfer effectiveness than visitation rate. Our findings highlight the importance of Old World bat pollinators within southern Thailand's mixed-agricultural landscape and illustrate how seemingly similar floral visitors can have very different contributions toward plant pollination success.绝大多数被子植物（angiosperm）依赖动物媒介完成传粉，其中涵盖诸多农业作物，而植物-传粉者互作关系已得到广泛研究。然而，并非所有访花者都能实际完成花粉传递，且在蝙蝠传粉相关研究文献中，区分真正传粉者与普通访花者的相关研究尤为匮乏。为探明泰国南部混合农业区的旧大陆蝙蝠物种是否同样具备高效传粉能力，本研究针对6种夜间开花的植物类群展开调查，并量化了7种常见食蜜蝙蝠物种的传粉重要性（Pollinator Importance, PI）。传粉重要性通过蝙蝠夜间访花频率（由雾网采样数据获得）与花粉传递效率（通过蝙蝠携带的花粉负荷估算）的乘积计算得到。本研究发现，传粉重要性因蝙蝠物种与植物物种的不同而存在差异。总体而言，食蜜特化型蝙蝠物种是更为重要的传粉者，但其重要性排序在不同焦点植物物种间存在差异。此外，传粉重要性更多由花粉传递效率而非访花频率主导。本研究结果凸显了泰国南部混合农业景观中旧大陆蝙蝠传粉者的重要性，并阐明了看似相似的访花者对植物传粉成功的贡献可能存在极大差异。
