Seasonal distributions and predicting migratory pathways for three species of bats

Understanding seasonal variation in the distribution and movement patterns of migratory species is essential to monitoring and conservation efforts. While there are many species of migratory bats in North America, little is known about their seasonal movements. In terms of conservation, this is important because the bat fatalities from wind energy turbines are significant and may fluctuate seasonally. Here we describe seasonally resolved distributions for the three species that are most impacted by wind farms (Lasiurus borealis [eastern red bat], L. cinereus [hoary bat], and Lasionycteris noctivagans [silver-haired bat]) and use these distributions to infer their most likely migratory pathways. To accomplish this, we collected 2880 occurrence points from the Global Biodiversity Information Facility over five decades in North America to model species distributions on a seasonal basis and used an ensemble approach for modeling distributions. This dataset included 1,129 data points for L. ...

阐明迁徙物种的分布与移动模式的季节变异规律，对物种监测与保护工作具有重要意义。尽管北美分布有多种迁徙蝙蝠，但学界对其季节性移动模式仍缺乏深入认知。从保护层面而言，这一认知缺口存在显著隐患：风能涡轮机造成的蝙蝠死亡数量可观，且该死亡数可能随季节发生波动。本研究针对受风力发电场影响最严重的三个蝙蝠物种——东方红蝠（Lasiurus borealis [eastern red bat]）、灰蓬毛蝠（L. cinereus [hoary bat]）以及银毛蝠（Lasionycteris noctivagans [silver-haired bat]）——构建了分季节分辨率的分布数据集，并基于这些分布数据推导其最可能的迁徙路径。为实现这一研究目标，我们从全球生物多样性信息设施（Global Biodiversity Information Facility）收集了近50年间北美地区的2880条物种出现记录，用于构建分季节的物种分布模型，并采用集成建模方法开展分布模拟。本数据集包含1129条关于L. ……的记录。
