Abstract

Abstract Patterns in the composition of assemblages of microbat species sampled during the late dry season (the ‘build-up’) in north Australian savannas were assessed against a range of environmental factors as well as four a priori defined habitat types (riparian, escarpments, coastal and woodlands). Distinct species assemblages were most strongly associated with topographic and climatic variables. There were also limited associations with vegetation structure, fire and local roost potential but no associations with insects or water availability. Total species diversity at sample sites was associated with distance to rivers and rainfall. In general, species assemblages were not clearly defined and the number of significant environmental associations was relatively few. We compare these associations with those reported for bat assemblages elsewhere in Australia.

澳大利亚热带稀树草原食虫蝙蝠群落的结构和环境关系

根据一系列环境因素以及四种先验定义的栖息地类型(河岸、悬崖、海岸和林地)，对澳大利亚北部稀树草原旱季后期取样的微蝙蝠物种组合的组成模式(“积累”)进行了评估。不同的物种组合与地形和气候变量的关系最为密切。与植被结构、火灾和当地栖息潜力也有有限的关联，但与昆虫或水的可用性没有关联。样点总物种多样性与河流距离和降雨量有关。总体而言，物种组合的定义不明确，重要环境关联的数量相对较少。我们将这些关联与澳大利亚其他地方报道的蝙蝠组合进行了比较。

期刊介绍： Austral Ecology is the premier journal for basic and applied ecology in the Southern Hemisphere. As the official Journal of The Ecological Society of Australia (ESA), Austral Ecology addresses the commonality between ecosystems in Australia and many parts of southern Africa, South America, New Zealand and Oceania. For example many species in the unique biotas of these regions share common Gondwana ancestors. ESA''s aim is to publish innovative research to encourage the sharing of information and experiences that enrich the understanding of the ecology of the Southern Hemisphere. Austral Ecology involves an editorial board with representatives from Australia, South Africa, New Zealand, Brazil and Argentina. These representatives provide expert opinions, access to qualified reviewers and act as a focus for attracting a wide range of contributions from countries across the region. Austral Ecology publishes original papers describing experimental, observational or theoretical studies on terrestrial, marine or freshwater systems, which are considered without taxonomic bias. Special thematic issues are published regularly, including symposia on the ecology of estuaries and soft sediment habitats, freshwater systems and coral reef fish.
