Drainage-Driven Loss of Carbon Sequestration of a Temperate Peatland in Northeast China
Drainage is known to reduce carbon sequestration in peatlands, but its effect on the stability of carbon pool and changes in recalcitrant organic carbon fractions remain relatively unknown, especially in tempe...

Effects of nitrogen and phosphorus additions on nitrous oxide fluxes in a peatland in NE China
The release of the major greenhouse gas N2O from peatlands may be affected by current global change. We tried to answer how N2O emission from peatlands responds to phosphorus (P) addition and the co-addition of P...

Contrasting effects of nitrogen and phosphorus additions on fine root production and morphological traits of different plant functional types in an ombrotrophic peatland
Changes in morphological traits of fine roots indicate shift in adaptive strategies. However, it remains unclear how nitrogen (N) and phosphorus (P) depositions change fine root adaptive strategies in peatland...

The effects of environmental, climatic and spatial factors on diatom diversity in Sphagnum peatlands in central and northeastern China
Peatlands are limno-terrestrial habitats that support rich microscopic algae, whereas algal distribution is poorly known in peaty environments. This study aims to explore diatom diversity patterns and underlyi...

Long-Term Phosphorus Addition Strongly Weakens the Carbon Sink Function of a Temperate Peatland
Peatlands are important nutrient-limited, carbon (C)-accumulating ecosystems where phosphorus (P) is one major limiting nutrient. An increase in P input to peatlands has been observed close to agricultural are...

Litter mixing effects on decomposition in a peatland partially drained 30 years ago
Litter decomposition is a key process controlling carbon (C) sequestration in Sphagnum dominated peatlands. Peatland drainage lowers the water table, increases vascular plant richness, and alters species evenness...

Different leaf carbon, nitrogen, and phosphorus stoichiometry and carbon and nitrogen isotopes among peatland plants in northeastern China
Plant carbon (C), nitrogen (N), phosphorus (P) levels and their stoichiometry and N uptake strategies are important aspects influencing vegetation composition and C dynamics in boreal peatlands. However, C, N ...

Open AccessVegetation and microbes interact to preserve carbon in many wooded peatlands
Peatlands have persisted as massive carbon sinks over millennia, even during past periods of climate change. The commonly accepted theory of abiotic controls (mainly anoxia and low temperature) over carbon dec...

Sphagnum spore banks in two montane peatlands at different elevations
Spore production of bryophytes is common in subalpine ecosystems, but how spore banks of bryophytes vary with elevations is unknown. We used peat cores from two Sphagnum dominated peatlands, a low- (780 m a.s.l.)...

Resource competition and allelopathy in two peat mosses: implication for niche differentiation
Separating the effect of resource competition from allelopathy in plants is challenging and it has never been attempted in closely related co-occurring bryophytes. In peatlands, peat mosses (Sphagnum spp.) show n...

Oxygen-deficiency and allelochemicals affect Sphagnum spore persistence in peatlands
To test the effects of characteristic ecological gradients in peatlands including oxygen-deficiency and allelopathy on Sphagnum spore persistence.

Degradation of polycyclic aromatic hydrocarbons (PAHs) during Sphagnum litters decay
The dynamics of polycyclic aromatic hydrocarbon (PAH) degradation in Sphagnum litters and the decomposition of the litters were investigated. PAH concentration decreased to approximately half of the initial conce...

Continuous Waterlogging May Not Facilitate Germinability Maintenance of Sphagnum Spores
Burial depth within soil affects the survival of seeds and spores in ecosystems. However, burial depth effect on germinability of Sphagnum spores received little attention. In a peatland in Northeast China, we co...

Direct and interaction-mediated effects of environmental changes on peatland bryophytes
Ecosystem processes of northern peatlands are largely governed by the vitality and species composition in the bryophyte layer, and may be affected by global warming and eutrophication. In a factorial experimen...

Age structures of modules of clonal peatland sedge Carex middendorffii
Age structure of a plant population carries important information on population dynamics. The traditional age classification of individuals by development phases could not explain the generation relationship n...
