Critical gaps in understanding how species respond to environmental change limit our capacity to address conservation risks in a timely way. Here, we examine the direct and interactive effects of key global change drivers, including climate change, land use change, and pesticide use, on persistence of 104 odonate species between two time periods (1980–2002 and 2008–2018) within 100 × 100 km quadrats across the USA using phylogenetic mixed models. Non-target effects of pesticides interacted with higher maximum temperatures to contribute to odonate declines. Closely related species responded similarly to global change drivers, indicating a potential role of inherited traits in species’ persistence or decline. Species shifting their range to higher latitudes were more robust to negative impacts of global change drivers generally. Inherited traits related to dispersal abilities and establishment in new places may govern both species’ acclimation to global change and their abilities to expand their range limits, respectively. This work is among the first to assess effects of climate change, land use change, and land use intensification together on Odonata, a significant step that improves understanding of multispecies effects of global change on invertebrates, and further identifies conditions contributing to global insect loss.

气候变化加剧了农药在宏观生态尺度上对蜻蜓的非目标效应

在理解物种如何应对环境变化方面存在重大差距，这限制了我们及时应对保护风险的能力。在这里，我们在 100 × 100 范围内研究了气候变化、土地利用变化和杀虫剂使用等关键全球变化驱动因素对两个时间段（1980-2002 和 2008-2018）之间 104 种齿形物种的持久性的直接和交互影响使用系统发育混合模型在美国进行 km 样方。农药的非目标效应与较高的最高温度相互作用，导致 odonate 下降。密切相关的物种对全球变化驱动因素的反应相似，表明遗传性状在物种持续或衰退中的潜在作用。将其范围转移到更高纬度的物种通常更能抵御全球变化驱动因素的负面影响。与传播能力和在新地方建立相关的遗传特征可能分别控制物种对全球变化的适应和扩大其范围限制的能力。这项工作是首批评估气候变化、土地利用变化和土地利用集约化对 Odonata 的影响的工作之一，这是提高对全球变化对无脊椎动物的多物种影响的理解的重要一步，并进一步确定了导致全球昆虫损失的条件。
