适应中等温度会对北极节肢动物的耐热性产生强烈的负面影响

北极地区受到地球上一些最快的气温变化的影响，但对陆生节肢动物的影响尚不清楚。高纬度地区陆生外温动物的急性生理热极限往往超过当地气温，这表明它们可能能够应对不断升高的温度。在这里，我们研究了在北极和亚北极栖息地采集五种陆生节肢动物（Neomolgus littoralis、Megaphorura arctica、Nysius groenlandicus、Psammotettix lividellus 和 Nabis flavomarginatus）后，适应温度和暴露时间如何影响它们的急性生理耐热性。我们的研究表明，虽然急性耐热性相对较高，但即使暴露在中等（温度跨度评估约为 3-29°C）的适应温度下 24 小时，也会对五个物种中四个物种的耐热性产生强烈的负面影响。总之，我们的研究结果表明，即使暴露在适度升高的温度下 24 小时甚至更短时间，也会导致亚北极和北极地区适应寒冷的陆生节肢动物急性耐热性降低。因此，导致长时间轻度高温的气候变化可能会对这些物种产生强烈的负面影响。我们认为，目前在评估北极和亚北极地区节肢动物应对气候变化的能力时忽略了这一方面，因为这种预测通常是基于对急性耐热性的估计和有益适应反应的假设。

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.
