Summary: The research indicates that Auto-DOM in karst ecosystems may be an important carbon sink, often overlooked as it is believed to be easily mineralized by planktonic bacteria. The fluorescence component C2 of CDOM may possess characteristics of RDOM and serve as a significant source of DOM in karst aquatic ecosystems. Additionally, high concentrations of Ca2+ and dissolved inorganic carbon (DIC) in karst ecosystems were found to impact certain planktonic bacterium and functional genes.

Summary: The study found that factors influencing public perceptions of aquatic ecosystems include environmental factors and sociocultural factors. Environmental factors include the presence of water plants and algae, floating debris, water odor, movement, clarity, and the overall aesthetic appeal of the ecosystem. Sociocultural factors include age, education, gender, and local knowledge.

Summary: Flow cytometry is a promising tool for identifying phenotypic features of bacterial communities in aquatic ecosystems through measuring light scattering and fluorescence of cells. Advanced statistical techniques can be used to calculate phenotypic diversity based on scatter data obtained from flow cytometry, which shows high correlation with taxonomic diversity computed using next-generation 16S RNA gene sequencing. The protocol provided in this paper serves as a useful guide for fast and reliable flow cytometric monitoring of bacterial phenotypic diversity in aquatic ecosystems.

Summary: The input of mercury (Hg) into ecosystems has increased significantly since the industrial revolution, and methylmercury (MeHg) is the most concerning species in aquatic ecosystems due to its neurotoxicity and ability to bioaccumulate in the food chain. Dissolved organic matter (DOM) plays a crucial role in the transformation of aquatic Hg. This study collected water samples from 373 sites globally and found that Hg availability was the dominant factor influencing MeHg concentration in water, followed by DOM.

Summary: Species dispersal and resource spatial flows have significant impacts on the dynamics of connected ecosystems. This study investigates the role of subsidy stoichiometry in mediating the response of a meta-ecosystem to subsidy flows. The results demonstrate the potential for positive feedback loops and increased production at the meta-ecosystem scale through spatial complementarity. However, accentuating the stoichiometric mismatch between local resources and basal species needs can also have a negative impact on production.

Summary: This study evaluated the effectiveness of 440 aquatic restoration projects in the northwest Taihu basin, China, finding significant improvements in water quality and benthic invertebrate biological indices across most of the study area, mainly due to projects targeting pollution sources.

Summary: Pharmaceuticals are widespread in aquatic ecosystems, causing environmental concerns. They are influenced by dissolved organic matter and bacterial communities, which are affected by human activities. This study investigates the occurrence and distribution of 35 pharmaceuticals in an urbanized bay in China and their relationship with dissolved organic matter and aquatic bacterial communities. The results show that pharmaceuticals are detected in surface water samples, mainly sulfonamides, macrolides, antidepressants, and stimulant metabolites. The concentrations of pharmaceuticals are positively correlated with human activities and urban expansion, and three fluorescent components have a strong positive correlation with the total concentration of pharmaceuticals. Pharmaceutical pollution also affects aquatic bacterial communities.

Summary: This study presents a preliminary exploration of the interaction between PFASs and biofilms in various aquatic environments. It discusses the biosorption properties of biofilms on PFASs and their possible mechanisms, as well as the complex impact of PFASs on biofilm systems. The study suggests that biofilms after adsorption of PFASs serve as a unique ecological niche and provide a potential microbial pool for PFASs biodegradation.

Summary: This study investigated the burial process of recalcitrant dissolved organic matter (RDOM) in Erhai lake, China, and found that autochthonous organic matter plays a significant role in the lake's carbon sink. It provides a new perspective for studying the stability of autochthonous organic matter and highlights the importance of studying carbon sinks in inland lakes.

Summary: Tropical aquatic ecosystems are impacted by warming, leading to a decrease in connectivity between terrestrial and aquatic habitats, as well as a reduction in the flux of aquatic resources to terrestrial ecosystems and variable effects on the breakdown of terrestrial resources in aquatic ecosystems. This could potentially impact consumers in both ecosystem types and disrupt cross-ecosystem dynamics in an interconnected tropical landscape.

Summary: The study reveals the presence of aerobic methane production in water bodies, which is associated with (bacterio)chlorophyll metabolism and photosynthesis, as well as with Proteobacterial degradation of methylphosphonate. These findings provide new insights into the mechanisms of aerobic methane production in aquatic ecosystems.

Summary: Climate change has led to salinization and nutrient enrichment in lake ecosystems, affecting bacterial communities. This study found that salinization has a greater impact on bacterial communities compared to nutrient enrichment. Salinization leads to convergent response of bacterial communities and alters interspecific interactions. The study also revealed the different patterns of topological parameters of bacterial communities in different salinity environments.

Summary: River and stream ecosystems in cities play a crucial role in maintaining biodiversity and providing ecosystem services to urban populations. However, the impacts of urbanization on biodiversity and ecosystem services are not well understood. This study aims to investigate the relationships between aquatic biodiversity, urbanization, and ecosystem services provided by urban streams.

Summary: The recent discovery of the invasive fungus Cryptostroma corticale in Seattle, Washington, USA is concerning due to its potential impact on both trees and human health. The fungus, which causes sooty bark disease, has been found to be well-distributed throughout western Washington, with a high detection rate in mature bigleaf maple trees. Although signs of the disease were rarely observed on individual trees, the overall condition of the bigleaf maples surveyed was considered healthy. Increased awareness of this fungus and the disease it causes can inform management strategies and highlight the need for further research.
