Environmental DNA exploring the distribution of Indo-Pacific humpback dolphins and fish diversity from the Pearl River Estuary, China.

Marine Pollution Bulletin
Understanding the spatial distribution patterns of endangered species is crucial for their protection. However, gathering such information for cetaceans remains challenging due to their underwater life and elusive nature.

Seasonal dynamics of bacterial community and co-occurrence with eukaryotic phytoplankton in the Pearl River Estuary.

Marine Environmental Research, 2023
In this study, we investigated the taxonomic composition of the bacteria and phytoplankton communities in the Pearl River Estuary (PRE) through Illumina sequencing of the V3-V4 region of the 16 S rRNA gene.

The concentration of CH4, N2O and CO2 in the Pearl River estuary increased significantly due to the sediment particle resuspension and the interaction of hypoxia.

Science of the Total Environment, 2023
Hypoxia and sediment particle resuspension (SPR) alter the biogeochemical cycle of estuarine and coastal seas, which in turn affects the production and emission of methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) greenhouse gases (GHGs) in ...

Driving Factors of Dimethylated Sulfur Compounds in the Pearl River Estuary and Its Adjacent Coastal Waters: The Nonnegligible Role of Synechococcus

Journal of Geophysical Research: Oceans
Estuaries serve significant roles in the global dimethylated sulfur compounds (DSCs) cycle, however, the driving factors and biological contribution still need to be elucidated.

Organotins in fish, shrimp, and cephalopods from the Pearl River Estuary, China: Dietary exposure risk to Indo-Pacific humpback dolphin and human.

Science of the Total Environment, 2023
Food has regularly been proven to be a key source of exposure to environmental pollutants, drawing attention to the dietary exposure risks of contaminants to mammals with significant daily food intake. Here, the levels of six organotin compounds (OTs) in

The formation mechanisms of turbidity maximum in the Pearl River estuary, China

Marine Pollution Bulletin, 2004
The formation and dynamics of turbidity maxima (TM) in the Pearl River estuary (PRE) are not well understood but the existence of TM in the estuary have great potential engineering and environmental impacts. Based on the measurements of two large-scale field surveys conducted in the wet season of 1978 (July of 1978) and the dry season of 1979 (March of

Degradation of polymeric carbohydrates coupled with cellular motility driving microbial niche separation in the Pearl River Estuary surface sediment.

Journal of Environmental Science
Estuaries are key areas for organic carbon cycling, where polymeric carbohydrates are abundant and chemically diverse. The recycling of these polymers by microbes depends on a variety of carbohydrate-active enzymes (CAZymes).

High levels of microplastic pollution in aquaculture water of fish ponds in the Pearl River Estuary of Guangzhou, China.

Science of the Total Environment, 2020
Microplastics (MPs) have caused great concern worldwide recently due to their ubiquity in the aquatic environment. The current knowledge on the occurrence of MPs in aquaculture fish ponds in a typical estuary system remains meagre.
