欧洲淡水鱼类和北美繁殖鸟类的功能多样性丧失和分类延迟

生物多样性具有时间动态性，反映了历史环境条件并影响生态系统的稳定性。定殖和灭绝动态经常表现出不同步的模式，导致净失衡，从而造成长期的丰富度趋势。利用欧洲淡水鱼类和北美繁殖鸟类的群落时间序列数据，我们研究了 fNICE 与其分类学等价物（tNICE）的不同之处，从而提供了一幅生物多样性动态的综合图景。我们的研究结果表明，分类学和功能延迟是一个普遍特征，它挑战了对环境变化立即做出反应的假设。分类延迟表现为灭绝债务和殖民信用，而功能延迟则表明随着时间的推移，功能增益和损失之间的平衡发生了变化。此外，我们还发现，分类学和功能失衡并不总是直接相关的，尽管在鱼类和鸟类中发现了一些特定的模式。早期的定殖超过了功能增益，这表明尽管新物种的到来早于其他物种的灭绝，但新功能特征的获得却滞后了。虽然这可能会暂时稳定群落，因为功能冗余可以减轻因局部灭绝而造成的功能丧失，但过度冗余会损害生物多样性应对环境变化的能力，从而破坏长期恢复力。虽然短期观察可能表明多样性与环境条件之间存在平衡，但我们的研究结果强调了考虑长期动态以及物种特征与不断变化的环境之间相互作用的重要性。tNICE和fNICE指标是量化这些时间动态并揭示其对生态系统稳定性影响的宝贵工具。将这些见解纳入保护战略有助于积极保护生物多样性和维护生态系统的完整性。

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.
