蜘蛛的生活史特征决定其体型对城市温度变化的反应

与农村环境相比，城市生态系统的环境条件发生了改变，包括温度升高，即所谓的城市热岛效应（UHI）。沿着城市化梯度，温度变化发生在从景观到微生境的不同尺度上，可能对生物造成影响。节肢动物作为外温动物，受 UHI 的影响尤为严重，因为气候变暖可能会直接对它们的新陈代谢产生生理影响。体型是研究节肢动物对热应力反应的常用指标，但温度变化作为体型预测因子的规模依赖性作用仍不清楚。为了评估跨空间尺度的温度-体型关系，并检验是否出现了多个物种的共同模式，我们对隶属于Hahniidae、Linyphiidae、Lycosidae和Tetragnathidae的11个蜘蛛物种的2283只个体进行了形态测量。我们在沿宽泛的超高压梯度分布的 36 块草地上采集了蜘蛛。在景观尺度和局部尺度上，鳞栉蛛科的Pardosa prativaga和Pardosa pullata的种内体型变化分别与温度有关，而对其他物种则没有观察到明显的影响。在这两个物种中，性别是调节个体反应的重要内源因素；雌性比雄性受温度的影响更大。在鳞翅目和其他物种中观察到的反应幅度对比表明，大型、低散布性和单伏性物种受温度的影响要强于可空中散布的小型双伏性物种。我们关于蜘蛛的研究结果突出表明，考虑物种特有的生活史特征有助于理解物种间的对比反应，这对于得出人为变暖条件下节肢动物表型变化的一般模式可能至关重要。在期刊博客上免费阅读本文的通俗语言摘要。

期刊介绍： Functional Ecology publishes high-impact papers that enable a mechanistic understanding of ecological pattern and process from the organismic to the ecosystem scale. Because of the multifaceted nature of this challenge, papers can be based on a wide range of approaches. Thus, manuscripts may vary from physiological, genetics, life-history, and behavioural perspectives for organismal studies to community and biogeochemical studies when the goal is to understand ecosystem and larger scale ecological phenomena. We believe that the diverse nature of our journal is a strength, not a weakness, and we are open-minded about the variety of data, research approaches and types of studies that we publish. Certain key areas will continue to be emphasized: studies that integrate genomics with ecology, studies that examine how key aspects of physiology (e.g., stress) impact the ecology of animals and plants, or vice versa, and how evolution shapes interactions among function and ecological traits. Ecology has increasingly moved towards the realization that organismal traits and activities are vital for understanding community dynamics and ecosystem processes, particularly in response to the rapid global changes occurring in earth’s environment, and Functional Ecology aims to publish such integrative papers.
