摘要

鸟类对环境变化非常敏感,而且由于其高度的流动性,可以迅速推动分布区的转移。尽管之前的研究已经考察了物种性状与分布区转移之间的关联,但对于物种性状是否仍能解释转移方向的异质性仍缺乏深入探讨。在此,我们整理了2000年至2019年的中国鸟类新记录,并分析了与明显迁徙方向相关的物种性状。我们收集了350个省级鸟类新记录,隶属于22目67科。其中,32种濒危,3种极危,11种濒危,18种易危。中国西部省份(即云南和西藏)新记录鸟类的物种丰富度相对较高;这一模式也反映在我们观察到的系统发育多样性中。此外,中国北方省份(即天津、山东和北京)的系统发育多样性受物种丰富度控制,相对较高。61.29%的省份(31 个省份中的 19 个)观察到新记录鸟类群落的系统发育过度分散。新记录鸟类的主要迁移方向是向北(近 50%的鸟类向西北、向北和向东北迁移)。迁徙、手翅指数(HWI)、体重和活动范围大小是对鸟类迁徙方向影响最大的四个关键因素,表明鸟类向新的适宜地区的迁徙随物种特异性的变化而变化。这些结果共同证明了在预测鸟类迁徙方向时考虑物种生态特征的重要性。

Where are the provincial-level new records in China from the past 20 years, and which traits determine their shift directions?
Birds are sensitive to environmental changes and can drive range shifts rapidly due to their high mobility. Though previous studies have examined the associations between species traits and range shifts, whether species traits could still explain heterogeneity in shift directions remains poorly explored. Here, we compiled new bird records of China from 2000 to 2019 and analyzed species traits associated with apparent shift directions. We collected 350 provincial-level new records of birds belonging to 67 families of 22 orders. Of these, 32 are threatened, with 3 critically endangered, 11 endangered, and 18 vulnerable. Provinces in western China (i.e., Yunnan and Xizang) had relatively higher species richness of new recorded birds; this pattern was also reflected in the phylogenetic diversity we observed. In addition, provinces in northern China (i.e., Tianjin, Shandong, and Beijing) had relatively higher richness-controlled phylogenetic diversity. Phylogenetic overdispersion of new recorded bird communities was observed in 61.29% of provinces (19 of 31). The main shift directions indicated by new bird records were northward (with nearly 50% of birds moving NW, N and NE). Migration, hand-wing index (HWI), body mass, and range size are the four key factors that most significantly influence the shift directions in bird species, suggesting that bird movement toward newly suitable areas varies with species-specific traits. Together, these results demonstrate the importance of considering species ecological traits when predicting shift directions of birds.

期刊介绍: Frontiers in Ecology and Evolution publishes rigorously peer-reviewed research across fundamental and applied sciences, to provide ecological and evolutionary insights into our natural and anthropogenic world, and how it should best be managed. Field Chief Editor Mark A. Elgar at the University of Melbourne is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics and the public worldwide. Eminent biologist and theist Theodosius Dobzhansky’s astute observation that “Nothing in biology makes sense except in the light of evolution” has arguably even broader relevance now than when it was first penned in The American Biology Teacher in 1973. One could similarly argue that not much in evolution makes sense without recourse to ecological concepts: understanding diversity — from microbial adaptations to species assemblages — requires insights from both ecological and evolutionary disciplines. Nowadays, technological developments from other fields allow us to address unprecedented ecological and evolutionary questions of astonishing detail, impressive breadth and compelling inference. The specialty sections of Frontiers in Ecology and Evolution will publish, under a single platform, contemporary, rigorous research, reviews, opinions, and commentaries that cover the spectrum of ecological and evolutionary inquiry, both fundamental and applied. Articles are peer-reviewed according to the Frontiers review guidelines, which evaluate manuscripts on objective editorial criteria. Through this unique, Frontiers platform for open-access publishing and research networking, Frontiers in Ecology and Evolution aims to provide colleagues and the broader community with ecological and evolutionary insights into our natural and anthropogenic world, and how it might best be managed.
