生态系统工程师塑造生态网络结构和稳定性：框架和文献综述

生态系统工程是一个无处不在的过程，在这个过程中，物种会影响物理环境，从而构建生态群落。然而，在综合或预测生态系统工程如何影响相互作用网络的结构和稳定性方面却鲜有建树。为了评估目前科学界对生态系统工程通过生境形成、生境改造和生物扰动对相互作用网络/食物网的影响的理解，我们查阅了涉及海洋、淡水和陆地食物网、植物授粉者网络和理论的文献。我们提供了一个概念框架，并确定了通过改变资源可用性和能量流、生境异质性和环境过滤对网络产生工程影响的三个主要途径。这三个过程通常是协同作用的，大多数研究报告称，工程会增加物种的丰富性。对于增加生境异质性从而增加可用壁龛数量的工程而言，这一点尤为明显。网络结构对生态系统工程的反应各不相同，但从本综述中可以看出一些规律。工程栖息地的异质性会增加网络中物种之间的联系数量，并提高联系密度。连接性会受到生态系统工程师影响的负面或正面影响，这取决于工程途径和工程师对物种丰富度的影响。我们讨论了生态系统工程师如何通过改变生态位空间、多样性、网络结构以及对工程影响的依赖性来稳定或破坏群落。理论与实证需要相互借鉴，以更好地整合生态系统工程与生态网络。从机理上理解生态系统工程特征如何塑造相互作用网络及其稳定性，对于预测物种灭绝非常重要，并可为保护和生态系统恢复提供重要信息。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.
