摘要

据预测，在所有生命形式中，生物体大小与丰度之间广泛观察到的负比例关系具有一个普遍的-0.75比例指数。我们通过分析 183 个温带森林地块（包括城市次生林、城市原始森林和非城市天然林）中树木和土壤中无脊椎动物的大小-密度关系，探索了大小-密度比例关系对生态系统演替和生物特征的依赖性。随着小生物数量的增加，城市树木和无脊椎动物群落的比例关系指数随着恢复（人工）林分年龄的增加而逐渐变陡。相比之下，非城市树木的比例关系在演替过程中趋于平缓，指数偏离-0.75，而城市树木和无脊椎动物群落在演替后期趋向于这一预测。我们的研究结果揭示了跨越多个营养级的树木和土壤无脊椎动物群落的体型结构是如何随着演替时间的推移，随着大体型生物与小体型生物相对丰度的增加而变化的。这项研究强调了生物特征和生态系统演替对生物体型和丰度比例关系的基本影响。

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.
