It has long been understood that stabilizing the global climate requires human carbon emissions to converge toward net zero (Matthews and Caldeira, 2008). Analysis by the Intergovernmental Panel on Climate Change (IPCC) suggests delays in achieving net zero emissions, or a temperature increase of more than 1.5°C, will necessitate even stronger action: net negative emissions. A very large-scale opportunity for carbon sequestrat...

Summary Here we report on the biodiversity and abundance of aerobic and anaerobic ammonium‐oxidizing bacteria in sediment samples from the Xinyi River, Jinagsu Province (China). The biodiversity of aerobic ammonium‐oxidizing bacteria in the sediment was assessed using the amoA gene as functional marker. The retrieved amoA clones were affiliated to environmental sequences from freshwater habitats. The closest cultivated relativ...
