The reporter learned from the State Forestry and Grassland Administration of China that China has added 18 new internationally important wetlands, including Yanqing Wild Duck Lake in Beijing, Jiuqu Shibawan in Daxinganling, Heilongjiang, and Baima Lake in Huai'an, Jiangsu. The fourth place in the world. On the same day, China held a home publicity event in Xixi, Hangzhou, Zhejiang, and released the monitoring results of the ecological status of China's internationally important wetlands in 2022. Wetland protection and restoration have achieved remarkable results, and degraded wetlands in Heilongjiang, Hubei, Shandong, and Hainan have been effectively restored.
Prokaryotes constitute the majority of sedimentary biomass, where they cycle organic carbon and regulate organic matter transformation. The microbes inhabiting sediment are diverse, and the factors controlling microbial community composition are not fully understood. Here, we characterized the prokaryotic community using 16S rRNA gene sequencing in 24 stratigraphic layers within a 89 cm (dated to ~1900 years old) sediment core from an anchialine sinkhole in the Bahamas with a stratified water column and anoxic bottom water. The microbial community was dominated by members of the Alphaproteobacteria, Dehalococcoidia, Gammaproteobacteria, Bathyarchaeota, and Campylobacter classes. Most interestingly, subsurface microbial community structure could be correlated to previous evidence for timewise changes in the main source of organic matter that was supplied to the sediment accumulating during the last 2000 years, which itself was caused by regional terrestrial vegetation changes. The C:N r
