摘要

天然洞穴在为温带地区的众多蝙蝠物种提供栖息地方面发挥着至关重要的作用。虽然人造结构支持生物多样性的潜力越来越受到关注,但关于人工隧道是否适合作为天然隧道的可行替代品的信息却很缺乏。在这项研究中,我们评估了伊比利亚半岛东北部(西班牙)大多数物种的蝙蝠在繁殖季节对水电站人工隧道的使用情况。2013 年至 2014 年期间,我们使用竖琴式陷阱和雾网监测了 37 个个性化隧道入口处的蝙蝠活动。为了了解影响蝙蝠栖息地利用的因素,我们建立了竞争模型,以评估周围景观、环境和隧道因素对洞穴栖息物种和普通物种的丰富度和丰度的影响,以及对其作为蝙蝠繁殖栖息地的适宜性的影响。我们共捕获并鉴定了 738 只蝙蝠,占欧洲西南部国家蝙蝠种类的 60%,其中包括三个地区性濒危物种和两个全球性濒危物种。其中,67%的调查隧道被蝙蝠使用。我们的研究结果表明,隧道的特点(如隧道高度、无格栅和地表径流覆盖)对所有蝙蝠群都有影响。相对湿度主要有利于带幼崽的雌性蝙蝠的数量和丰度。如果设计和管理得当,水电站的人工隧道可以为蝙蝠提供重要的栖息和繁殖场所,从而在蝙蝠保护方面发挥重要作用;但是,必须考虑这些基础设施对当地生态系统的其他潜在生态影响。

Artificial tunnels of hydroelectric power plants as valuable habitat for European bats

Artificial tunnels of hydroelectric power plants as valuable habitat for European bats

Natural caves play a crucial role in providing habitat for numerous bat species in temperate regions. While the potential of man-made structures to support biodiversity gains attention, there is a lack of information regarding the suitability of artificial tunnels as viable alternatives to natural ones. In this study, we assessed the use of artificial tunnels of hydroelectric power plants by bats in the NE Iberian Peninsula (Spain) during the breeding season for most species. Between 2013 and 2014, we monitored bat activity in 37 individualized tunnel entrances using harp traps and mist nets. To understand factors influencing their habitat use, we built competitive models to assess the effect of surrounding landscape, environment and tunnel factors on the richness and abundance of both cave-dwelling and generalist species, as well as on its suitability as breeding habitat for bats. We captured and identified a total of 738 bats representing 60% of species occurring in the South-West countries of Europe, including three regionally and two globally threatened species. Of the total, 67% of surveyed tunnels were used by bats. Our findings highlight that tunnel characteristics such as tunnel height, absence of grilles, and cover of surface runoff influenced all bat groups. Relative humidity primarily favours richness and abundance of females with pups. When properly designed and managed, man-made tunnels of hydroelectric power plants can play an important role in bat conservation by offering essential roosts and breeding sites; however, other potential ecological impacts of these infrastructures on local ecosystems must be considered.

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.
