湖泊细菌群落构建机制及其对富营养化的响应

The assembly mechanisms of bacterial communities in lakes and their responses to eutrophication

细菌是湖泊生态系统的重要组成部分,在驱动湖泊生态系统元素物质循环和调控湖泊水质方面发挥关键性作用。揭示湖泊细菌群落多样性的形成和维持机制,即群落构建机制,是湖泊微生物生态学研究中的核心目标。近年来,微生物组学技术的发展,极大推动了湖泊细菌群落构建机制的研究。富营养化是当前我国湖泊生态系统面临的最大环境挑战之一,也是决定湖泊细菌群落组成和多样性的重要因素。研究综述了湖泊细菌群落构建机制的理论基础和发展脉络。概述了湖泊细菌群落构建机制的主要分析方法。总结了富营养化对湖泊细菌群落构建机制的影响的最新研究进展。针对富营养化影响下湖泊细菌群落构建机制研究所面临的问题,提出了未来的研究展望。

Bacteria are important components of lake ecosystems,playing a crucial role in driving the cycling of elements and regulating water quality in lakes.Uncovering the mechanisms underlying the formation and maintenance of bacterial community diversity in lakes,known as community assembly mechanisms,is a central objective in the study of microbial ecology in lakes.In recent years,the development of microbiomics has greatly promoted the understanding of the assembly mechanisms of bacterial communities in lakes.Eutrophication represents one of the most important environmental challenges faced by lake ecosystems in China today,and it is also a nonnegligible factor determining the composition and diversity of bacterial communities in lakes.This article firstly provides a review of the theoretical foundations and the developmental context of bacterial community assembly mechanisms in lakes.Secondly,it outlines the main analytical methods used in studying the assembly mechanisms of bacterial communities in lakes.Next,it summarizes the latest research advancements in understanding the impact of eutrophication on the assembly mechanisms of bacterial communities in lakes.Finally,it discusses future research prospects and the challenges faced in studying the assembly mechanisms of bacterial communities in lakes under the influence of eutrophication.
