Intensive mariculture activities result in eutrophication and enhance coastal deoxygenation. Deoxygenation profoundly influences nitrate reduction processes further the fate of nitrogen (N) systems. Herein, 15N isotope labeling, real-time PCR, high-throughput sequencing techniques were jointly used to investigate participation seasonal dynamics sediment pathways succession functional microbial communities during development deoxygenation a aquaculture zone. Denitrification dominated benthic...
Abstract Woody plant encroachment into graminoid‐dominated freshwater marshes is a widespread phenomenon globally, yet the mechanisms driving it are not well understood. It often presumed that establishment of woody plants—encompassing seed germination, seedling survival, and growth—is influenced by environmental changes such as alterations in water regimes nutrient availability. However, this hypothesis has been rigorously tested through empirical studies. In study, we conducted 3‐year...
Global warming is likely to influence the soil microorganisms and enzyme activity alter carbon nitrogen balance of peatland ecosystems. To investigate difference in sensitivities cycling warming, we conducted three-year experiments a boreal peatland. Our findings demonstrated that both mcrA nirS gene abundance shallow deep exhibited insensitivity while archaea 16S rRNA amoA increased under warming. Soil pmoA layers, bacterial soil, nirK decreased due The decreases these abundances would be...
Soil microbes and enzymes in permafrost peatland are sensitive to temperature changes, which might result more potential loss of carbon increase available nitrogen from peatlands a warming world. We previously demonstrated that 3-year could affect soil microbial abundance enzymatic activity. However, activity under long-term climate is not well understood. Therefore, 6-year field manipulation experiment was used assess the impact on northeastern China. Results showed increased bacteria 0 15...
Abstract. Permafrost thawing in peatlands has the potential to alter catchment export of dissolved organic carbon (DOC), thus influencing balance and cycling linked aquatic ocean ecosystems. Peatlands along southern margins Eurasian permafrost are relatively underexplored despite considerable risks associated with degradation due climate warming. This study examined dynamics DOC from a peatland located northeastern China during 2012 2014 growing seasons. The estimated annual loads varied...
Permafrost soils act as large sinks of organic carbon but are highly sensitive to interference such changes in land use, which can greatly influence dissolved loads streams.
The Da Xing’an Mountain is a key distribution area for Chinese boreal forests and fire-prone area. Frequent forest fires have influenced on the regional carbon cycle enormously, especially influence of soil respiration. Thus, understanding post-fire respiration important in study global balance. This chose different fire intensities burned 2006 near unburned as objectives this were to (1) investigate its components after disturbances; (2) determine relationship between temperature water...
Zonation along a water level is the main spatial distribution characteristic of wetland plants. This mainly because influences hydrological conditions and interspecific competition, which finally narrow fundamental niche species to its realized niche. In present study, controlled experiment was conducted in order analyze relationship between Carex lasiocarpa/Carex pseudocuraica Glyceria spiculosa, three competitive treatments at four levels. The results showed that no C. lasiocarpa preferred...
