摘要

蝙蝠在哺乳动物中是独一无二的,它们具有动力飞行能力,在新热带地区具有高度的物种多样性和觅食习性。尽管近几十年来人们对新热带蝙蝠分布情况的了解有了显著增加,但有关该物种在巴西各地分布情况的信息仍然很不统一,在许多生物群落中都存在很大的知识空白。位于塞阿拉西北部的乌巴哈拉国家公园(PNU)是卡廷加生物群落中生物多样性极其丰富的地区,这里有多个天然洞穴,洞穴中的蝙蝠群落十分引人注目。在此,我们对 PNU 的蝙蝠多样性进行了补充性调查,重点调查了六个洞穴及其周围的觅食地点。我们使用雾网、竖琴式陷阱、栖息地搜索和声学监测等补充方法进行了两次调查,共计 36 个采样夜。共记录到 8 个科 30 种蝙蝠。我们发现采样方法之间有明显的互补性,从而使稀有度曲线趋于稳定。在至少一个取样洞穴中发现了 8 种蝙蝠的栖息群。使用主动采样技术共记录到 18 个物种的 965 个个体,其中大部分属于蚜蝇科。被动声学监测获得了 14 种不同的声型,分别来自 Emballonuridae、Mormoopidae、Molossidae、Vespertilionidae 和 Noctilionidae 科。不同科的蝙蝠在旱季的声学活动较多,并且在整个夜间活动不一。在捕获的蝙蝠中,有两个物种是通过被动声学监测登记的,这进一步说明了方法多样化对获得更完整的蝙蝠清单的重要性。

Bats (Mammalia: Chiroptera) of Ubajara National Park, Ceará, Brazil: a diversity assessment using complementary sampling methods

Bats are unique among mammals in their capacity for powered flight and present high species diversity and feeding habits in the Neotropical region. Despite the remarkable increase in knowledge on the distribution of neotropical bats in recent decades, information on the species’ occurrence throughout Brazil is still widely heterogeneous, with significant knowledge gaps in many biomes. The Ubajara National Park (PNU), northwestern Ceará, is an area of extreme biodiversity in the Caatinga biome, characterized by several natural caves associated with a noticeable bat community. Herein, we carried out a complementary inventory of bat diversity in the PNU, focusing on six caves and their surrounding foraging sites. Two surveys totaling 36 sampling nights were conducted using complementary methods such as mist nets, harp trap, roosting searches, and acoustic monitoring. Thirty species of bats belonging to eight families were recorded. We found significant complementarity between the sampling methods resulting in the stabilization of the rarefaction curve. Eight species were found in roosting colonies in at least one of the sampled cavities. A total of 965 individuals from 18 species, with the majority belonging to the family Phyllostomidae, were recorded using active sampling techniques. Passive acoustic monitoring yielded 14 different sonotypes of species from the Emballonuridae, Mormoopidae, Molossidae, Vespertilionidae, and Noctilionidae families. The acoustic activity of bats from distinct families was higher in the dry season and varied throughout the night. Two species registered with passive acoustic monitoring were among the captured ones, thus reinforcing the importance of diversifying methodologies to obtain more complete bat inventories.

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.
