Freshwater lakes are increasingly subject to simultaneous nutrient enrichment and antibiotic pollution, yet the joint effects of these stressors on microbial network structure remain poorly characterized. This study examined the combined effects of nutrients and antibiotics on bacterial communities across eight bays in Erhai Lake, which were classified into high-, moderate-, and low-pollution zones. High-pollution bays (Haichao, Dongsha, and Shuanglang) recorded the region's highest nutrient concentrations, with chemical oxygen demand reaching 33.

The differentiation of the nitrate reduction pathway is of great significance in the ecosystem, as it determines the occurrence form of ecosystem N. In order to explore the impact and mechanism of different algal dissolved organic nitrogen (DON) and dissolved organic phosphorus (DOP) on differentiation of nitrate (NO-N) reduction pathway, small-scale enclosure experiment was conducted to analyze the DON and DOP composition, nutrient level, microbial community composition and NO-N reduction pathway in ponds with Microcystis and Dolichospermum blooms. The main DON produced by Microcystis included lipids and proteins as well as carbohydrate which were readily degradable, whereas the DOP produced by Dolichospermum predominantly consists of readily degradable forms such as carbohydrate and protein.

Inland water ecosystems play key roles in the production, transportation, transformation, storage, and consumption of global greenhouse gases (GHG). Different water body types exhibit spatial and temporal differences after considering factors such as season and aquatic plant life forms. The results revealed that the annual global warming potential (GWP) (Tg CO-eq yr) from swamps, rivers, lakes, and reservoirs in China were 1382.

Marine heatwaves (MHWs) are increasing in frequency and intensity worldwide, significantly impacting marine ecosystems. However, studies on phytoplankton community changes in coastal waters under such conditions remain. In the summer of 2024, an extreme high-temperature event (>28 °C) occurred in the southern coastal waters of Korea, providing an opportunity to investigate phytoplankton community dynamics under thermal stress.

Shallow lakes are increasingly subjected to pronounced alterations in hydrological regimes and exacerbated nutrient stoichiometric imbalances due to climate change and anthropogenic factors. Understanding the interactions between watershed eco-hydrological processes and lake systems, particularly their impact on nutrient balance dynamics deserves further investigation. Employing seasonal-trend decomposition (STL), Copula modeling, and the Lindeman-Merenda-Gold (LMG) algorithm, this study systematically analyzed eco-hydrological processes in Poyang Lake basin and identified hydrological regime as the key factor governing lake nutrient balance.
