2. 摘要

人类活动可能加速了种群丰度的下降，但这种加速尚未被充分探索。利用1033条北美繁殖鸟类调查路线，我们分析了1987年至2021年间261种鸟类、54个鸟类科和10个栖息地的丰度变化及其加速情况。我们显示，各条局部路线下所有鸟类丰度在全大陆平均下降，北美南部和温暖地区出现下降热点，中大西洋、中西部和加利福尼亚则出现加速下降热点，与农业强度的模式相匹配。总体来看，122种（47%）出现显著下降，其中63种也显示下降加速，67种人均增长率下降，这引发了北美大部分鸟类种群的担忧。这些发现表明鸟类数量下降大多加速，这种加速的空间模式表明农业强度可能是这一趋势的驱动因素。

原文摘要（English）

Human activities might have accelerated declines of population abundance, but this acceleration remains underexplored. Using 1033 North American Breeding Bird Survey routes, we analyze abundance change and its acceleration for 261 bird species, 54 avian families, and 10 habitats from 1987 to 2021. We show an average continent-wide decline of abundance of all birds per local route, with hotspots of decline in southern and warm parts of North America and hotspots of accelerating decline in the Mid-Atlantic, Midwest, and California, matching patterns of agricultural intensity. Overall, 122 species (47%) exhibit significant declines, of which 63 also show acceleration of this decline, and 67 show declining per-capita growth rate, raising concerns for a large part of North American bird populations. These findings suggest that bird abundance decline is mostly accelerating, with spatial patterns of this acceleration indicating that agricultural intensity may be a driver of this trend.
