全球生物多样性的丧失使了解物种对快速环境变化的反应的调节因素变得更加紧迫。虽然专家对快速环境变化的适应力往往不如通才，但当当地适应性种群在气候耐受力方面存在差异时，物种水平的分析可能会掩盖专业化的程度。直到最近，由于缺乏基因组和跟踪信息，在物种水平以下量化候鸟的气候专业化程度受到阻碍，但最近的技术进步有助于克服这些障碍。在这里，我们采取全基因组遗传方法来绘制种群特异性迁徙路线，并量化遗传上不同的候鸟种群内的生态位宽度，杨柳霸鹟（Empidonax traillii），其在整个繁殖范围内表现出种群下降严重程度的变化。虽然我们的样本量仅限于物种内遗传上不同的种群数量，但我们的研究结果支持这样一种观点，即在整个季节中具有狭窄气候生态位的杨柳霸鹟的本地适应种群已经被联邦政府列为濒危或急剧下降，而具有更广泛气候生态位的种群在近几十年来保持稳定。总的来说，这项工作强调的价值，量化生态位宽度在不同的遗传群体跨越时间和空间时，试图了解的因素，促进或限制当地适应人口的快速环境变化的反应。
Global loss of biodiversity has placed new urgency on the need to understand factors regulating species response to rapid environmental change. While specialists are often less resilient to rapid environmental change than generalists, species‐level analyses may obscure the extent of specialization when locally adapted populations vary in climate tolerances. Until recently, quantification of the degree of climate specialization in migratory birds below the species level was hindered by a lack of genomic and tracking information, but recent technological advances have helped to overcome these barriers. Here we take a genome‐wide genetic approach to mapping population‐specific migratory routes and quantifying niche breadth within genetically distinct populations of a migratory bird, the willow flycatcher (Empidonax traillii), which exhibits variation in the severity of population declines across its breeding range. While our sample size is restricted to the number of genetically distinct populations within the species, our results support the idea that locally adapted populations of the willow flycatcher with narrow climatic niches across seasons are already federally listed as endangered or in steep decline, while populations with broader climatic niches have remained stable in recent decades. Overall, this work highlights the value of quantifying niche breadth within genetically distinct groups across time and space when attempting to understand the factors that facilitate or constrain the response of locally adapted populations to rapid environmental change.
