Thermal stratification has become more extensive and prolonged because of global warming, this change had a significant impact on the distribution patterns phytoplankton communities. However, response community structures assembly processes to thermal is not fully understood. We predicted that structure communities would be affected by among water layers associated with environmental condition changes, reflecting certain in temporal spatial scales. Phytoplankton from Danjiangkou Reservoir were collected October 2021 July 2022 verify prediction. During sampling period, remained thermally stratified stability. The composition surface layer significantly differed both thermocline bottom layer. phenomenon pattern nitrogen phosphorus and, thus, structures. Deterministic greater influence layers. In contrast, stochastic prevalent community. within exhibited broader niche range than layers, showing notable dissimilarity Canonical correspondence analysis (CCA) revealed vertical distributions correlated NH4+-N, pH, temperature (WT). summary, study explained deep-water reservoirs during period. Additionally, explored potential using stratified-state under subtropical–warm temperate climate as indicators context warming.

How ecological regimes and emergent macrophytes determine sediment microbial communities: A new insight into typical eutrophic shallow lakes

Abstract Understanding the response of microbial communities to different ecological regimes in eutrophic lakes and underlying assembly mechanisms is great significance for revealing biodiversity maintenance lake ecosystems under alternative stable states. However, our current understanding sediment emergent macrophytes regime shifts remains limited. Here, we demonstrated, first time, asynchronous variations littoral bacterial fungal communities, regarding diversities, mechanisms, inter‐kingdom interactions across three regional regimes: macrophyte‐dominated, transitional, phytoplankton‐dominated. We found alpha diversities showed opposite trends, as transitional had highest but lowest diversities. Stochastic processes, dominated by dispersal limitation, determined community assembly, whereas deterministic especially variable selection, shaped community. The number species–environment proportion intra‐kingdom were observed co‐occurrence network regime; however, this (bacteria–fungi) among regimes. Furthermore, macrophyte‐dominated was have most complex structure maintain stability. rhizosphere Phragmites australis enhanced communities. These findings provide a preliminary perspective hysteresis environmental stress at level emphasize importance distinguishing ecologically distinct taxa future studies focused on
