In Eastern Europe, wind energy production is currently promoted as an important source of renewable energy, yet in most cases without appropriate consideration of the negative impacts wind turbines (WT) may have on protected species such as bats. Here, we present first data on fatality rates, fatality factors and the likely origin of bats killed by WT in the Dobrogea region (Romania), located in a major migratory corridor for wildlife in Eastern Europe. Over a 4-year period, we found a total of 166 bat carcasses from 10 species, mostly representing migratory species such as Pipistrellus nathusii and Nyctalus noctula. Most fatalities at WT occurred in July and August. We documented 15 cases of barotrauma and 34 cases of blunt-force trauma in carcasses found below WT. After adjusting for carcass removals and variations in searcher efficiency, we estimated for the 4-year study period a total of 2394 bat casualties at the studied WT facility consisting of 20 units, resulting in a mean fatality rate of 30 bats/WT/year, or 14.2 bats/MW/year. By implementing a curtailment measure at wind speeds below 6.5 m/s, we reduced fatality rates by 78%. Isoscape origin models based on hydrogen stable isotope ratios in fur keratin revealed that the majority of N. noctula that were killed by WT or captured nearby in mist nets originated from distant areas in the North (Ukraine, Belarus, Russia). The estimated high fatalitjegangy rates of bats at WT in this area have far-reaching consequences, particularly for populations of migratory bats, if no appropriate mitigation schemes are practised.

野生动物和基础设施：风力涡轮机对黑海沿岸蝙蝠的影响

在东欧，当前将风能生产作为可再生能源的重要来源加以推广，但是在大多数情况下，没有适当考虑风力涡轮机（WT）对蝙蝠等受保护物种的负面影响。在这里，我们介绍了位于东欧野生动植物迁徙的主要走廊多布罗加地区（罗马尼亚）的死亡率，死亡率因素以及被WT杀死的蝙蝠的可能起源的第一份数据。在4年的时间里，我们从10个物种中发现了166个蝙蝠尸体，其中大多数代表迁徙物种，如Napiusii和Nyctalus noctula。。WT的死亡人数最多是在七月和八月。我们记录了在WT下方发现的15具屠体中的气压伤和34例钝器外伤。调整屠体去除量和搜索者效率的差异后，我们在为期4年的研究期间估计，在研究的WT设施（包括20个单位）中，总共有2394蝙蝠的伤亡，平均致死率为30蝙蝠/ WT /年，或14.2磅/兆瓦/年。通过在风速低于6.5 m / s时实施缩减措施，我们将死亡率降低了78％。基于毛皮角蛋白中氢稳定同位素比率的Isoscape起源模型显示，大部分夜蛾猪笼草被WT杀死或被附近北方（乌克兰，白俄罗斯，俄罗斯）遥远地区产生的薄雾网捕获的生物。如果没有采取适当的缓解措施，估计该地区野生动物蝙蝠的致命致命高发率将产生深远的影响，特别是对于候鸟的种群。
