Metagenomic data highlight shifted nitrogen regime induced by wetland reclamation
Natural wetlands are mostly nitrogen-limited ecosystems, while reclamation stimulates the loss of nitrogen (N) in soils by shifting the N regime. To investigate the microbial mechanisms of the N regime shift, ...

Open AccessWarming-induced vapor pressure deficit suppression of vegetation growth diminished in northern peatlands
Recent studies have reported worldwide vegetation suppression in response to increasing atmospheric vapor pressure deficit (VPD). Here, we integrate multisource datasets to show that increasing VPD caused by w...

Open AccessPractical Guide to Measuring Wetland Carbon Pools and Fluxes
Wetlands cover a small portion of the world, but have disproportionate influence on global carbon (C) sequestration, carbon dioxide and methane emissions, and aquatic C fluxes. However, the underlying biogeoch...

Soil nitrate mediates the responses of plant community production to the frequency of N addition in a temperate grassland: a decadal field experiment
Nitrogen (N) enrichment through either artificial N application or atmospheric N deposition often increases ecosystem aboveground net primary productivity (ANPP). Therefore, results from N addition experiments...

Effect of different factors dominated by water level environment on wetland carbon emissions
The exacerbation of global warming has led to changes in wetland carbon emissions worldwide. Therefore, we conducted a meta-analysis of methane (CH4) and carbon dioxide (CO2) emissions in wetland ecosystem and ex...

Dominant species and evenness level co-regulate litter mixture decomposition in a boreal peatland
In boreal peatlands, climate warming and associated soil drying facilitate the growth of vascular plants at the cost of moss species, resulting in an alteration of species dominance in plant communities. Howe...

Is Moss Stoichiometry Influenced by Microtopography in a Boreal Peatland of Northeast China?
To examine the effects of microtopography on the stoichiometry of carbon (C), nitrogen (N) and phosphorus (P) in mosses along the hummock-hollow gradient in boreal peatlands, we investigated species-level C׃N,...

Nitrogen addition in a freshwater marsh alters the quality of senesced leaves, promoting decay rates and changing nutrient dynamics during the standing-dead phase
Nitrogen (N) is often the nutrient limiting the decomposability of shoots from macrophytes in wetlands. We aimed to determine the effects of increasing soil N availability on the decomposition of shoots during...

Litter mass loss and nutrient dynamics of four emergent macrophytes during aerial decomposition in freshwater marshes of the Sanjiang plain, Northeast China
In wetland ecosystems, the litter of emergent macrophytes generally begins to decay while standing, but aerial decomposition has often been overlooked. The goal of this study was therefore to elucidate the pro...
