脚蹼和翅膀：运动环境是哺乳动物前肢形态多样性进化的驱动力

四足类动物在陆地环境中的早期分化涉及对其运动装置的适应，使其能够在不均匀的表面上支撑和推进重量。许多类群后来又回到了水中，而其他类群则征服了空中环境，在连续流体介质中运动的物理限制下进一步实现了多样化。虽然许多研究探讨了在连续介质中运动与体重之间的关系，但没有一项研究关注连续介质如何影响肢体形状多样性的宏观进化模式。我们研究了离开陆地环境以空气和水作为主要运动环境的哺乳动物是否经历了对其前肢形态进化的限制，评估了其形态差异和趋同的程度。我们收集了涵盖哺乳动物现存科级多样性的 800 多个物种的综合样本，利用对前肢骨骼的线性测量来确定其形状和大小。在哺乳动物中，完全水生类群的前肢形状差异最大，这可能是由于鳍肢扮演着多种不同的功能角色，或者是由于鳍肢内部骨骼比例的限制放宽了。与此相反，空中运动与前肢形状多样性受限有关。蝙蝠和滑翔哺乳动物表现出相似的形态模式，导致部分表型趋同，主要涉及前肢近端节段的伸长。因此，水生运动推动了前肢形状的多样化，而空中运动则限制了前肢的多样化。这些结果表明，在连续流体介质中运动既可以促进也可以限制形态多样性，更广泛地说，运动环境促进了哺乳动物前肢的形态和功能进化。在期刊博客上免费阅读本文的通俗摘要。

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.
