增强植物枯落物对混交林中线虫群落和碳利用效率的影响

气温升高和大气中二氧化碳含量升高可能会增加植物的光合作用并提高森林生产力，从而在全球范围内刺激废弃物向土壤的输入。线虫代表了土壤生物区系中的所有营养群。因此，我们研究了线虫代谢活动与植物枯落物投入量之间的联系。为此，我们在温带森林中控制了不同的枯落物输入水平，包括不含枯落物的对照区、天然枯落物输入区以及双倍、三倍和四倍天然枯落物输入区。然后收集土壤表层（0-10 厘米），研究线虫群落的反应。更多的枯落物会增加食菌线虫在食菌线虫和食真菌线虫总数中的比例。更多的枯落物增加了食菌线虫的 K/r 策略比率以及相应的线虫代谢足迹。更多的枯落物也刺激了线虫的生产和呼吸作用，提高了细菌食肉动物的碳利用效率。总之，我们的研究表明，增加植物地上枯落物会改变土壤线虫的分类群落和功能群落，最终调节森林土壤的碳循环。

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.
