Seasonal variations in greenhouse gas production in coastal sandy sediments.

Understanding the greenhouse gas (GHG) production rates and ecological effects of sandy coastal sediments is critical for refining global carbon cycle assessments. Despite their extensive distribution and potential role in climate regulation, sandy sediments remain understudied compared to muddy counterparts, particularly regarding seasonal dynamics and redox-controlled biogeochemical processes. This study investigates seasonal GHG dynamics in sandy coastal sediments of the Guangdong Province, China.

Biomicroplastics and Antibiotics: A Toxic Cocktail for Fatty Liver Disease in Marine Medaka.

The increasing production and use of bioplastics contribute to the accumulation of bioplastic debris in marine environments. The impact of such debris, particularly when combined with co-occurring pollutants like antibiotics, on marine life remains largely unexplored. In this study, we demonstrate that coexposure to aged polylactic acid (PLA) biomicroplastics and the antibiotic sulfamethazine (SMZ) induces overweight (an increase of 20.

Niche overlap between native Cirrhinus molitorella and potential invasive competitors.

Biological invasion is one of the important reasons for the decline of freshwater biodiversity in China and even in the world. The Pearl river basin is one of the most threatened areas in China by biological invasion. Over the past four decades, mrigal carp Cirrhinus mrigala and rohu Labeo rohita have invaded the Pearl river.

Enrichment of antibiotic resistant genes and pathogens in face masks from coastal environments.

Face masks (FMs) are essential to limit the spread of the coronavirus during pandemic, a considerable of which are accumulated on the coast. However, limited is known about the microbial profile in the biofilm of the face masks (so-called plastisphere) and the impacts of face masks on the surrounding environments. We herein performed face mask exposures to coastal sediments and characterized the microbial community and the antibiotic resistome.
