最近对生物多样性多维性质的认识促使生物学家研究自然群落的分类、功能和系统发育属性。同时考虑这种多重多样性维度为各种群落组装过程提供了有价值的见解。我们在一个简单的岛屿景观上研究了蚂蚁多样性的α和β组成部分，该景观以邻近但非生物独特的常绿（潮湿和茂密的树冠）和滨海（干燥和稀疏的树冠）森林栖息地为主。我们试图（i）描述和检查蚂蚁多样性维度的相互关系，以及（ii）通过比较观察到的和随机生成的群落的多样性模式来识别构建蚂蚁群落的潜在过程。我们发现，干燥的沿海栖息地具有较低的蚂蚁物种丰富度和非随机群落组成，但具有与常绿森林相似的功能多样性。这一结果与之前比较完整栖息地和人类改变栖息地的研究形成鲜明对比，这些研究报告称蚂蚁功能多样性严重丧失，丰富度降低。在我们的研究中，栖息地之间的功能相似性得以维持，因为沿海森林中的群落在功能上过度分散，超出了偶然的预期。我们认为，蚂蚁的竞争和/或耐热性可能会导致滨海蚂蚁群落的过度分散。在我们岛屿的小空间尺度上，尽管功能性状和非随机功能多样性模式具有显着的系统发育信号，但系统发育多样性对栖息地差异的预测效果不佳。我们的工作强调需要进行广泛的研究来比较邻近栖息地的多维多样性，这将为解释人为压力导致的群落水平变化提供基线。
Recent appreciation of the multidimensional nature of biodiversity has prompted biologists to examine the taxonomic, functional, and phylogenetic attributes of natural communities. Simultaneous consideration of such multiple diversity dimensions provides valuable insights into various community assembly processes.We studied the alpha and beta components of ant diversity on a simple island landscape dominated by adjacent but abiotically distinct evergreen (humid & dense canopy) and littoral (dry & sparse canopy) forest habitats. We sought to (i) describe and examine interrelationships of ant diversity dimensions, and (ii) identify potential processes structuring ant communities by comparing the diversity patterns of observed and randomly generated communities.We found that the drier littoral habitat had lower ant species richness and non‐random community composition, but had similar functional diversity as evergreen forests. This result is in contrast with previous studies comparing intact and human‐altered habitats that reported severe loss of ant functional diversity with reduced richness. In our study, the functional similarity between habitats was maintained because communities in littoral forests were functionally overdispersed than expected by chance. We suggest that competition and/or thermal tolerance of ants may drive overdispersion of littoral ant communities.At the small spatial scale of our island, phylogenetic diversity was a poor predictor of habitat differences despite significant phylogenetic signal in functional traits and non‐random functional diversity patterns. Our work highlights the need for a broad range of studies comparing multidimensional diversity in adjacent habitats that would provide a baseline for interpreting community‐level changes due to anthropogenic pressures.
