“…Understanding community assembly mechanisms is crucial for maintaining and promoting ecosystem functions and services ( 21 , 22 ). It is generally accepted that deterministic and stochastic processes are both important in facilitating the assembly of microbial communities ( 23 – 25 ). Determinism is largely dictated by selection (e.g., competition and mutualism), environmental conditions, and interspecies interactions that govern community structure, whereas stochasticity is characterized by random ecological drift, dispersal, and speciation ( 24 , 26 ).…”

Riparian wetlands comprise microbial communities that are easily affected by the surrounding conditions, especially in agricultural landscapes with a wide range of ecosystem services. After comparing the wet and dry season microbiota, we found that the soil bacterial community of the wet season exhibited a higher complexity and stability of soil bacterial network and stronger dispersal limitations than that of the dry season; however, the dry season bacteria showed stronger homogeneous selection than the wet season bacteria.

“…These results may be because of alternative species or shifts in the relative abundance of dominant species within communities. When assessing the reservoir aquatic ecology in the region, the beta diversity may be more responsive to the impacts of environmental factors on ecological communities [22].…”

Phytoplankton diversity and community characteristics are closely associated with aquatic environmental factors. Understanding these dynamics can provide insights into the ecological health of water bodies. We investigate the spatial and temporal characteristics of phytoplankton communities in 27 drinking water source reservoirs in Shenzhen, China. As a method, we collected samples during the dry season in 2021 and the wet season in 2022, analyzed the alpha and beta diversities of phytoplankton communities, and correlated these with the environmental factors. The results reveal that Cyanobacteria dominate the phytoplankton communities in the Shenzhen reservoirs. Phytoplankton diversity is greater during the dry season. The algal composition varies spatially, and the phytoplankton diversity tends to decrease with increasing eutrophication. A co-occurrence network analysis indicates denser and stronger correlations among phytoplankton nodes during the wet season than dry season. Reservoirs with moderate eutrophication levels exhibit denser nodes and stronger correlations compared to those with low or high eutrophication levels. The chemical oxygen demand, water temperature, pH, and total nitrogen are identified as key influencers of the phytoplankton community structure. Our results contribute to the enhanced understanding of the spatial and temporal dynamics of phytoplankton communities in reservoirs in South China and provides insights into the management and conservation of these drinking water reservoirs.
