Fungal endophytes modulate the negative effects induced by Persistent Organic Pollutants in the antarctic plant Colobanthus quitensis.

Antarctica has one of the most sensitive ecosystems to the negative effects of Persistent Organic Pollutants (POPs) on its biodiversity. This is because of the lower temperatures and the persistence of POPs that promote their accumulation or even biomagnification. However, the impact of POPs on vascular plants is unknown.

Antibiotic resistance genes (ARGs) are emerging environmental pollutants, posing an escalating threat to public health and environmental security worldwide. However, the relationship between ARGs and microbial communities in the environment, as well as their ecological effects on the microbe-mediated materials cycle remain unclear. In this study, we investigated the spatial distribution pattern, influence mechanism, relationship with microorganisms, and their effects on the elemental cycling of ARGs in East China Sea sediments.

Exploring the changes in plant functional traits and their relationship with the environment in karst climax communities across different latitudes can enhance our understanding of how these communities respond to environmental gradients. In this study, we focus on climax karst climax plant communities in Guizhou Province, China. We selected three sample sites located at varying latitudes and analyzed the variations in functional traits of the plant communities at these latitudes.

Climate change will increase the frequency and severity of temperature extremes. Links between host thermal physiology and their gut microbiota suggest that organisms' responses to future climates may be mediated by their microbiomes, raising the question of how the thermal environment influences the microbiome itself. Vertebrate gut microbiomes influence the physiological plasticity of their hosts via effects on immunity, metabolism, and nutrient uptake.

Permafrost soils store vast amounts of organic carbon, and their thawing due to climate warming accelerates the release of carbon as methane and carbon dioxide, exacerbating global climate change. Understanding the distribution of greenhouse gases trapped in these soils and predicting their behavior upon thawing is essential for accurately modeling climate feedbacks. This study presents an integrated biogeochemical and microbial dataset from ~1.
