Phylogeny, traits and biodiversity of a neotropical bat assemblage: close relatives show similar responses to local deforestation

If species’ evolutionary pasts predetermine their responses to evolutionarily novel stressors, then phylogeny could predict species survival in an increasingly human-dominated world. To understand the role of phylogenetic relatedness in structuring responses to rapid environmental change, we focused on assemblages of Neotropical bats, an ecologically diverse and functionally important group. We examined how taxonomic and phylogenetic diversity shift between tropical forest and farmland. We then explored the importance of evolutionary history by ascertaining whether close relatives share similar responses to environmental change and which species traits might mediate these trends. We analyzed a 5-year data set (5,011 captures) from 18 sites in a countryside landscape in southern Costa Rica using statistical models that account and correct for imperfect detection of species across sites, spatial autocorrelation, and consideration of spatial scale. Taxonomic and phylogenetic diversity decr...

若物种的演化历史预先决定了其对演化上全新胁迫因子的响应，那么系统发育（phylogeny）便可用于预测在人类主导程度日益加剧的世界中物种的存活前景。为阐明系统发育亲缘关系在塑造物种对快速环境变化响应中的调控作用，我们聚焦于新热带区蝙蝠类群——这是一类生态多样且功能重要的生物类群。我们探究了热带森林与农田之间分类多样性与系统发育多样性的变化格局。随后，我们通过验证亲缘关系相近的物种是否对环境变化具有相似响应，以及哪些物种性状可介导此类变化趋势，探究了演化历史的重要性。我们采用可校正不同采样点间物种不完全检测、空间自相关问题并兼顾空间尺度效应的统计模型，对哥斯达黎加南部乡村景观中18个采样点的5年监测数据集（共5011次捕获记录）进行分析。分类多样性与系统发育多样性呈下降……
