摘要

测量生态系统多功能性（EMF）可能是一种有价值的方法，可用于评估基于自然的解决方案（如引入非本地物种以促进生态系统功能）是否会产生净正面结果。虽然 EMF 指标可提供系统功能的粗略概览，但此类指标可能会掩盖同时发生的多种生态系统功能之间的相互作用。这可能会限制 EMF 指标在管理环境变化对生态系统功能影响方面的预测价值和总体功效。我们在新西兰奥特亚罗瓦（Aotearoa）的一个牧场生态系统中进行了一个中型宇宙实验，对引入的蜣螂（Onthophagus binodis 和 Onitis alexis）对多种生态系统功能产生的级联生物效应和非生物效应进行了量化。我们测量了受蜣螂影响的九种生态系统功能，包括粪便清除、土壤总碳、氮、磷、土壤微生物呼吸、硝酸氮、铵氮、厌氧可矿化氮和牧草生物量生产。我们首先测试了时间性蜣螂多样性对九种生态系统功能的影响。然后，我们通过使用平均法、阈值法和希尔数法计算EMF指标，检验了引入的蜣螂时间多样性如何影响生态系统的多功能性。最后，为了研究各个功能之间的潜在相互作用，我们使用结构方程模型（SEM）检验了引入的蜣螂对九个生态系统功能的直接和间接影响。在九项生态系统功能中，只有一项受到引入蜣螂的显著影响，而在计算出的六项EMF指标中，有五项随着引入蜣螂的时间多样性而显著增加。我们的研究结果表明，引入和增加蜣螂的时间多样性会增强生态系统的多种功能，但我们检测和解释生态系统多功能性变化的能力关键取决于如何量化EMF。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.
