Wind energy has rapidly become an important alternative among renewable energies, and it is generally considered clean. However, little is known about its impact at the level of ecological communities, especially in biodiversity hotspots. The Isthmus of Tehuantepec is a highly biodiverse region in Mesoamerica, and has the highest potential for generating wind energy in Mexico. To assess the effects of installing a wind farm on the understory bat community in a landscape of fragmented habitat, we assessed its diversity and composition over four stages of installation (site preparation, construction, and two stages of operation). We captured 919 bats belonging to 22 species. Species richness, functional diversity and phylogenetic diversity decreased during construction and the first stage of operation. However, these components of biodiversity increased during the second stage of operation, and species composition began to resemble that of the site preparation stage. No species considered as sensitive to disturbance was recorded at any stage. This is the first study to reveal the diversity of a Neotropical bat community after wind turbines begin to operate.
风能已迅速成为可再生能源中的一种重要替代能源，并且通常被认为是清洁能源。然而，人们对其在生态群落层面的影响知之甚少，尤其是在生物多样性热点地区。特万特佩克地峡是中美洲一个生物多样性极高的地区，也是墨西哥风能发电潜力最大的地区。为了评估在栖息地破碎化的景观中安装风力发电场对林下蝙蝠群落的影响，我们在安装的四个阶段（场地准备、建设以及运营的两个阶段）评估了蝙蝠群落的多样性和组成。我们捕获了属于22个物种的919只蝙蝠。在建设阶段和运营的第一阶段，物种丰富度、功能多样性和系统发育多样性有所下降。然而，在运营的第二阶段，生物多样性的这些组成部分有所增加，并且物种组成开始类似于场地准备阶段。在任何阶段都未记录到被认为对干扰敏感的物种。这是第一项揭示风力涡轮机开始运行后新热带蝙蝠群落多样性的研究。
