The consumption of fruits and floral resources, as core or complementary food items, occurs in 75% of phyllostomid species. If phylogenetically related bat species have similar plant species in their diets, then it is expected that vegetal resources composition influences the phylogenetic structure of phyllostomid assemblages. We ask here if the phylogenetic structure of phyllostomid assemblages is associated with vegetation structure and resources. Our results showed that proportions of plant sources consumed by phyllostomids in the Pantanal wetland have phylogenetic signal, and that variation of the available vegetal resources influences the phylogenetic structure of phyllostomid assemblages. Considering the availability of their principal food resources, the two major phyllostomid clades (Phyllostominae and Stenodermatinae) responded in opposite ways to the vegetal resources gradient, formed by plant species with distinct adaptations to inundation. Our results indicate that the use of different habitats based on variation of vegetal resources is the main driver of phylogenetic structure of phyllostomid assemblages in the Pantanal wetland.

植物资源驱动新热带湿地叶口蝠群落的系统发育结构

75% 的叶螟物种以水果和花卉资源作为核心或补充食品。如果系统发育相关的蝙蝠物种在其饮食中具有相似的植物物种，那么预计植物资源组成会影响叶状昆虫组合的系统发育结构。我们在这里询问 phyllostomid 组合的系统发育结构是否与植被结构和资源有关。我们的研究结果表明，潘塔纳尔湿地叶口类动物消耗的植物资源比例具有系统发育信号，可用植物资源的变化影响了叶口类植物组合的系统发育结构。考虑到其主要食物资源的可用性，两个主要的叶状动物进化枝（Phyllostominae 和 Stenodermatinae）对植物资源梯度的反应方式相反，植物资源梯度由对淹没具有不同适应性的植物物种形成。我们的研究结果表明，基于植物资源变化的不同生境的利用是潘塔纳尔湿地叶嘴类群系统发育结构的主要驱动因素。
