六种热带木本植物沿热梯度的光合作用热耐受性的季节性适应变化

我们的具体研究问题是(1) 六种重点物种的植物个体在不同季节是否会适应其热耐受性？根据之前在沸腾河观察到的种内温度调节特征和热耐受性对总体生长温度的不同反应（Kullberg 等人，2024 年），我们假设在温度调节方面可塑性更强的物种也将表现出更强的提高热耐受性的能力。(2) 耐热性适应的程度是否与最高气温（ΔTmax）的微地级季节差异的程度有关？我们预计，叶片温度与气温密切相关的物种，其适应反应应取决于 ΔTmax 的大小，而叶片温度受太阳辐射等其他因素影响较大的物种，其适应反应与 ΔTmax 的大小关系不大或没有关系。了解亚马逊植物物种适应温度变化的能力将提高我们预测气候变化对热带森林影响的能力。

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.
