摘要:

为研究湿地公园开发过程中水域微生物群落结构和共现网络的响应特征,收集了西溪国家湿地公园3个不同功能区(保育区、景观区和娱乐区)中54个池塘水体样品,通过微生物高通量测序及分子生态网络分析发现,湿地开发影响了微生物群落的多样性和生态网络复杂性.其中,景观区水域表现出较高的网络连接度和鲁棒性,表明植物覆盖增加了湿地公园水体微生物群落的复杂性和稳定性.此外,水体叶绿素a、硝态氮、总氮均与细菌-古菌域间网络复杂度相关(r分别为0.28、-0.28和-0.38,P<0.05),这表明水体营养状态可能调控着微生物间的相互作用.

Abstract:

To investigate how microbial community structure and co-occurrence networks respond to wetland park development, we collected water samples from 54 ponds across three functional zones(conservation zone, landscape zone, and recreation zone) in Xixi National Wetland Park. Using high-throughput sequencing and molecular ecological network analysis, we found that wetland development influenced microbial diversity and ecological network complexity. Specifically, the landscape zone exhibited higher network connectivity and robustness, suggesting that plant coverage enhanced the complexity and stability of aquatic microbial communities in wetland parks. Furthermore, chlorophyll-a, nitrate nitrogen, and total nitrogen were significantly correlated with the complexity of inter-domain bacteria-archaea networks(r=0.28,-0.28,-0.38,P<0.05), indicating that water nutrient status may regulate microbial interactions.
