Abstract

ABSTRACT Bats are a complex and diverse group, making their study remarkably challenging. Several methods allow the study of bats, e.g. mist-nets and acoustic monitoring (AM). We compare the use of AM and mist-nets to inventory bats in a mountainous region of São Paulo state, Brazil. We provide a species list for the study area based on species registered with both methodologies, comparing with a species list known for the state, obtained from the literature. We calculated beta diversity between methodologies to evaluate the dissimilarity in species composition sampled with these methods. We also performed a PCA to evaluate if the bat fauna sampled with AM showed species-habitat associations. We recorded 15 species/sonotypes through AM and 22 species through mist-nets. Beta diversity revealed 97% of dissimilarity in species composition. The turnover component explained 96% of this dissimilarity. PCA revealed that Vespertilionidae bats were associated with border/cluttered habitats, while Molossidae bats were present in all habitat types. The species list for the state comprises eighty species. Our inventory recorded more than 25% of this fauna. Mist-nets are efficient for sampling low-flying/low-intensity echolocating bats. AM is crucial for sampling high-flying/high-intensity echolocating bats. This is the second study to use AM to inventory bats in this state.

传统与创新:比较生物声学和雾网结果与蝙蝠取样

蝙蝠是一个复杂多样的群体，这使得蝙蝠的研究极具挑战性。有几种方法可以研究蝙蝠，例如雾网和声学监测（AM）。我们比较了在巴西圣保罗州山区使用AM和雾网清点蝙蝠的情况。我们提供了一份基于两种方法登记的物种的研究区域物种清单，并与从文献中获得的该州已知物种清单进行了比较。我们计算了不同方法之间的β多样性，以评估用这些方法采样的物种组成的差异。我们还进行了主成分分析，以评估AM采样的蝙蝠动物群是否显示出物种栖息地关联。我们通过AM记录了15种/声型，通过雾网记录了22种。β多样性揭示了97%的物种组成差异。营业额部分解释了这种差异的96%。PCA显示，Vespertionidae蝙蝠与边界/杂乱的栖息地有关，而Molossidae蝙蝠存在于所有栖息地类型中。该州的物种清单包括80种。我们的库存记录了超过25%的这种动物。雾网对低空飞行/低强度回声定位蝙蝠的采样非常有效。AM对于高飞行/高强度回声定位蝙蝠的采样至关重要。这是第二项使用AM对该州蝙蝠进行盘点的研究。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
