The loss of tropical forest cover caused by land-use change is causing changes in populations of animal trophic guilds, including those belonging to Phyllostomidae bat species. They fulfill important ecosystem functions such as pollination, seed dispersion, and regulations of vertebrate and invertebrate populations in Neotropical forests and human disturbed habitats. However, the effect of habitat disturbance on the abundance of phyllostomid bats is still controversial, and it is unknown if this effect presents a phylogenetic signal, or if this abundance is influenced by the type of forest where the disturbance occurs or by the distance between disturbed habitat and conserved forest. In order to answer these new questions, an exhaustive literature review was performed followed by a series of meta-analyzes. We found 26 studies from which 829 cases (i.e. species observations; k) were extracted. Each case reported the number of individuals captured in the disturbed habitat and in the conserved forest. As effect size, the bat proportion in disturbed habitats was used. We did not use phylogenetic correction in the meta-analysis because we did not find a phylogenetic signal in the bat proportion in disturbed habitats. We found that omnivorous, carnivorous, insectivorous and hematophagous bats were sensitive to habitat disturbance, while phytophagous were tolerant. In addition, the type of habitat disturbance and the type of forest where it occurs explain the differences of bat abundance within each trophic guild. Finally, there was no effect of the type of crop, the age of the secondary forest, and the distance to a conserved forest on trophic guild bat abundance in disturbed habitats. These results could focus the conservation efforts of phyllostomid bats and the ecosystem services they provide in both anthropogenic and conserved habitats.

营养的行会和森林类型解释了叶绿体蝙蝠的丰度因人类栖息地干扰而发生变化

土地利用变化引起的热带森林覆盖率的下降,导致动物营养协会的数量发生变化,包括属于鳞孔蝠的物种。它们履行重要的生态系统功能,例如授粉,种子扩散以及新热带森林和人类干扰栖息地中脊椎动物和无脊椎动物种群的调控。然而,栖息地干扰对叶甲类蝙蝠数量的影响仍存在争议,并且尚不清楚这种影响是否会带来系统发育信号,或者是否受干扰发生的森林类型或受干扰之间的距离影响。栖息地和森林保护区。为了回答这些新问题,进行了详尽的文献综述,随后进行了一系列荟萃分析。ķ)被提取。每个案例都报告了在受干扰的栖息地和受保护的森林中被捕的人数。作为影响大小,使用蝙蝠比例在受干扰的栖息地。我们没有在荟萃分析中使用系统发育校正,因为在受干扰的栖息地中蝙蝠比例中没有发现系统发育信号。我们发现杂食性,食肉性,食虫性和食血性蝙蝠对栖息地扰动敏感,而食植物性蝙蝠则能耐受。此外,栖息地干扰的类型和发生干扰的森林的类型解释了每个营养协会中蝙蝠数量的差异。最后,在受干扰的生境中,营养类公会蝙蝠的丰度对农作物类型,次生林的年龄以及与保护林的距离没有影响。
