摘要
随着气候的变化,许多物种的分布正在发生变化。许多分布变化可预测地向极地或海拔更高,但物种内部和物种之间变化的速率和方向的异质性似乎很常见。我们发现,北美东部65种鸟类的冬季范围变化轨迹以及与这些变化相关的不同性状和性状相互作用具有高度异质性。我们使用圣诞鸟类统计的数据来量化北美65种鸣禽和啄木鸟在40年间(1980-2019)的冬季纬向中心丰度范围变化轨迹,包括整个北美东部(ENA)以及大西洋(ATL)和密西西比(MISS)的飞行路线。然后,我们使用线性模型和Akaike 's Information Criterion with small-sample size correction (AICc)模型选择来检验物种特征是否可以解释距离移动或飞行路径差异的变化。在整个ENA中,大多数物种表现出向北的纬向移动,但也有一些物种没有纬向移动,而另一些物种则向南移动。在ATL和MISS中,我们记录了物种内和物种间纬度变化速率和方向的差异,使整个ENA的结果复杂化。在ENA和飞行路径尺度上,没有单一性状成为范围转移差异的主要驱动因素。在最大空间尺度(ENA)上,迁徙策略与食虫性相互作用可以解释变异,而在最大空间尺度(ENA)上,果食性和平均冬季纬度分别解释了ATL和MISS的大部分变异。探索物种内部和物种之间范围变化的异质性,以及范围变化与生活史特征之间的联系,将有助于我们更好地理解介导对环境变化的不同反应的机制,并预测哪些物种能够更好地适应这些变化。
Winter range shifts and their associations with species traits are heterogeneous in eastern North American birds
Abstract Many species’ distributions are shifting in response to climate change. Many distributional shifts are predictably poleward or higher in elevation, but heterogeneity in the rate and direction of shifts both within and between species appears to be common. We found high heterogeneity in the trajectory of winter range shifts for 65 species of birds across eastern North America and in the different traits and trait interactions associated with these shifts across the spatial scales we examined. We used data from the Christmas Bird Count to quantify the trajectory of winter latitudinal center of abundance range shifts over 4 decades (1980–2019) for 65 species of songbirds and woodpeckers in North America, both across eastern North America (ENA) as a whole and for the Atlantic (ATL) and Mississippi (MISS) flyways separately. We then used linear models and Akaike’s Information Criterion with small-sample size correction (AICc) model selection to test whether species traits could explain variation in range shifts or flyway discrepancies. Across ENA, most species showed northward latitudinal range shifts, but some showed no latitudinal shift while others shifted southwards. Amongst ATL and MISS, we documented both within- and between-species differences in the rate and direction of latitudinal shifts, complicating the results from across ENA. No single trait emerged as a dominant driver of range shift differences at the ENA and flyway scales. Migration strategy interacted with insectivory to explain variation at the largest spatial scale (ENA), whereas frugivory and mean winter latitude explained much of the variation in ATL and MISS, respectively. Exploring heterogeneity in range shifts within and between species, and in the associations between range shifts and life history traits, will help us better understand the mechanisms that mediate differing responses to environmental change and predict which species will be better able to adapt to those changes.
