摘要

生态学的一大挑战是了解不同物种如何相互作用以决定生态系统的功能,尤其是在有大量物种共存的群落中。我们利用基于性状的微生物垃圾分解模型来量化不同类群对生态系统功能的影响。此外,我们还建立了一个新颖的框架,强调分类群性状与环境条件之间的相互作用,重点关注它们对群落相互作用和生态系统功能的综合影响。我们的研究结果表明,类群对生态系统的影响受其资源获取特征和群落功能能力的驱动,但生理压力会放大正负相互作用的影响。此外,即使微生物与其他类群存在成对的负向相互作用,也会对生态系统功能产生净正面影响。随着群落随着全球气候变化而变化,我们的发现揭示了从类群特征和相互作用预测群落生物地球化学功能的潜力。

The Impact of Microbial Interactions on Ecosystem Function Intensifies Under Stress

A major challenge in ecology is to understand how different species interact to determine ecosystem function, particularly in communities with large numbers of co-occurring species. We use a trait-based model of microbial litter decomposition to quantify how different taxa impact ecosystem function. Furthermore, we build a novel framework that highlights the interplay between taxon traits and environmental conditions, focusing on their combined influence on community interactions and ecosystem function. Our results suggest that the ecosystem impact of a taxon is driven by its resource acquisition traits and the community functional capacity, but that physiological stress amplifies the impact of both positive and negative interactions. Furthermore, net positive impacts on ecosystem function can arise even as microbes have negative pairwise interactions with other taxa. As communities shift in response to global climate change, our findings reveal the potential to predict the biogeochemical functioning of communities from taxon traits and interactions.

期刊介绍: Ecology Letters serves as a platform for the rapid publication of innovative research in ecology. It considers manuscripts across all taxa, biomes, and geographic regions, prioritizing papers that investigate clearly stated hypotheses. The journal publishes concise papers of high originality and general interest, contributing to new developments in ecology. Purely descriptive papers and those that only confirm or extend previous results are discouraged.
