The eastern oyster (Crassostrea virginica) is an ecologically and economically important species that provides invaluable services for coastal communities. industry has a long history tradition in the U.S. Gulf Coast states, but this fishery declined dramatically recent years following Hurricane Katrina, Deepwater Horizon oil spill, freshwater flooding events. Mississippi was once known as "seafood capital of world," no commercial harvest from reefs occurred since 2018–2019 season.

Cyanobacteria harmful algal blooms (cHABs) are increasing in frequency, intensity and duration estuaries worldwide. In the upper San Francisco Estuary, also known as Sacramento Joaquin Delta (Delta), cHABs have been a topic of concern over past two decades. response, managers urgently working to understand factors that drive identify feasible management options avert ecological human health consequences. We used six year data set explore relationships between flow parameters, temperature, Microcystis biovolume determine potential for managing large scale hydrodynamic conditions address cHABs. looked at relationship low salinity zone see if it could be proxy residence time, because time is positively related cyanobacteria abundance. found not useful area experiences most severe Our finding suggest climatic (i.e., temperature water type) greatest influence on Delta, with higher during years lower temperatures. Further, there interannual differences cannot fully explained by parameters or meaning other included our model may involved. conclude actions increase ineffective reducing desired levels temperatures remain high.

Abstract Diverse microbial communities play a crucial role in maintaining the proper functioning of river ecosystems and are considered important indicators water quality. Although Seine River being heavily impacted by human activities, little is known about its surface waters. In order to monitor quality promote sustainable use, we studied diversity using high-throughput sequencing technology, explored their relationships with physico-chemical properties. The dominant phyla identified were Proteobacteria , Actinobacteriota Bacteriodota Cyanobacteria . presence Alphaproteobacteria Gammaproteobacteria indicates that nutrient profile mainly determined recalcitrant organic compounds present WWTP effluents. Bacterial showed significant temporal variability highly difference bacterial composition between 2020 2021, probably due variations flow favoring growth. Summer displayed higher activity abundance than autumn, attributed temperature orthophosphate content. Spatial variation was observed sites upstream downstream Paris, as well before after Valenton-WWTP, subject an accumulation phenomenon wastewater treatment. Further assessment emerging contaminants other pollutants required better understand these variations. These results provide basic understanding community River, serving reference for assessing impact implementing new disinfection techniques near future. Graphical abstract
