在过去的三十年中，越来越多的证据表明，许多非洲-古北地区的候鸟数量遭受了持续和严重的下降。由于这些下降的原因存在于繁殖期和非繁殖期，因此确定种群变化的潜在驱动因素是复杂的。为了探讨区域和局部环境条件的变化对种群变化的影响，我们研究了欧洲最丰富的非洲-古北夏季候鸟之一柳莺（Phylloscopus trochilus）种群轨迹的时空变化。
Aim Over the past three decades, evidence has been growing that many Afro‐Palaearctic migratory bird populations have suffered sustained and severe declines. As causes of these declines exist across both the breeding and non‐breeding season, identifying potential drivers of population change is complex. In order to explore the roles of changes in regional and local environmental conditions on population change, we examine spatial and temporal variation in population trajectories of one of Europe’s most abundant Afro‐Palaearctic summer migrants, the willow warbler, Phylloscopus trochilus.
