E-mail: jyang@iue.ac.cnThe increasing frequency, worldwide spatial expansion and toxicity of Raphidiopsis raciborskii blooms call for information on the mechanisms behind its formation and disappearance.Moreover, in deep lakes and reservoirs around the world, Raphidiopsis raciborskii exhibits a more invasive and expansive trend, and following Microcystis, has become to the first cyanobacterial blo...

Response of soil viral communities to land use changes
Soils are intrinsically diverse partially due to their wide compositional spectrum and spatial heterogeneity in terms of physicochemical properties, supporting a high diversity of interacting microbes that are pivotal to ecosystem services including global C and N biogeochemical cycles. Viruses are extremely abundant and diverse biological entities on earth, playing vital ro...Soils are intrinsically diverse partially due to their wide compositional spectrum and spatial heterogeneity in terms of physicochemical properties, supporting a high diversity of interacting microbes that are pivotal to ecosystem services including global C and N biogeochemical cycles.

Quaternary ammonium disinfectants exposure promoted bacterial antibiotic resistance in soils
As antibiotics are restricted or even banned in animal production, more disinfectants are used to maintain adequate sanitation to prevent bacterial diseases. Disinfectant usage is much higher than antibiotics, especially during the flu pandemic. Therefore, widely used quaternary ammonium disinfectants, have exacerbated the problem of antimicrobial resistance due to co- and c...As antibiotics are restricted or even banned in animal production, more disinfectants are used to maintain adequate sanitation to prevent bacterial diseases.

E-mail: lcui@iue.ac.cnSoil antimicrobial resistance (AMR) is posing increasing health risks due to possible transmission to humans through direct contact and through the food chain. However, soil AMR studies have relied mostly on environmental DNA that could come from dead/dominant cells and extracellular DNA, leading to potential overestimation of AMR and associated risks because the vast majori...

New study identifies main drivers of government investment in clean energy innovation
New forms of international cooperation and technology competition with China are the main drivers of public investment in energy innovation, though it remains insufficient to help meet climate goals.As the ongoing Russo-Ukrainian War to strain global energy supplies, some European countries have begun to cut back on their use of oil and natural gas. Other countries, however,...

Researchers Investigate Spatial Distribution of Reservoir Plankton Communities in Southeast China
Distance-decay relationships (DDRs) represent a very useful approach to describing the spatial distribution of biological communities. However, plankton DDR patterns and community assembly mechanisms are still poorly understood at different spatial scales in reservoir ecosystems. We collected phytoplankton, zooplankton and water samples in 24 reservoirs from subtropical and ...Distance-decay relationships are the most well-established biogeographical patterns in describing species spatial distribution in ecology. The decay of community similarity with geographical distance has been recognized by ecologists for several decades. The ecologists compared the distance-decay patterns of different communities at local, regional and continental scales.Res...
