Summary: This study numerically investigates the morphological and effective hydraulic properties of ground vegetation in the Western Siberian Lowland. The results show that the arctic cryptogamic cover can be considered an open and well-connected porous medium with good permeability. However, the digitally estimated hydraulic conductivity is higher than the results obtained from field and laboratory experiments, possibly due to compressibility effects during measurements.

Summary: The research shows that during peatland development, both vascular plant and Sphagnum moss communities exhibit trait trade-offs, but Sphagnum mosses display greater resistance to environmental change compared to vascular plants. Functional diversity increases in Sphagnum communities during peatland development, while it decreases in vascular plant communities.

Summary: The study conducted a comprehensive N and P budget for a forested bog in northern Minnesota, revealing N accumulation in the ecosystem but a balanced annual P input. The biomass stoichiometry showed that different plant functional types differ in N versus P limitation.

Summary: Northern peatlands are important carbon stores, and the re-establishment of bryophytes after fire is crucial for carbon sequestration. This study demonstrates that smoke can enhance the germination of bryophyte spores, with the effect increasing along the fire frequency gradient. The findings suggest that an increase in fire frequency can lead to shifts in species dominance, impacting long-term carbon sequestration in peatlands.

Summary: This study found a direct connection between Sphagnum traits, peatland hydrology, and carbon cycling. Compressed Sphagnum peat in hummocks was found to stabilize gross primary production (GPP) and enhance resistance to drought. Therefore, this research is crucial for understanding the carbon cycling mechanisms in peatlands.

Summary: This study investigated a polluted peatland near a smelter in Sudbury, Ontario, Canada, and found higher concentrations of copper and nickel in areas close to the smelter, which exponentially decreased with distance. 16S rDNA amplicon sequencing showed that the community structure of peat was more diverse compared to Sphagnum moss, and the latter was not significantly affected by distance from the smelter. The results provide insights into the microbiomes of peat and Sphagnum moss, as well as the sensitivities and resilience of peatland ecosystems.

Summary: Peatlands act as a carbon sink and a record of atmospheric metal deposition, but air pollution can negatively impact Sphagnum mosses and subsequently affect carbon and metal accumulation in peat. This study examines how the loss of Sphagnum in peatlands near a copper and nickel smelter in Sudbury, Ontario, influences carbon accumulation and metal profiles in peat. The depth of accumulated peat increased with distance from the smelter, while the peat bulk density decreased. Despite high pollution loadings, the average rates of carbon accumulation were within the range of published values. Surface peat close to the smelters had higher concentrations of copper and nickel, with copper profiles in dated peat cores reflecting known pollution histories better than nickel profiles.

Summary: The majority of Dutch peatlands are drained for dairy farming, resulting in damage to ecosystem services. Peatland rewetting and wetland agriculture offer alternative land use options, but their performance is rarely compared to drainage-based agriculture.

Summary: Research indicates that increasing gaseous emissions from oil sands development in northern Alberta have altered regional nitrogen and sulfur deposition, with bog plant/lichen tissue chemistry serving as effective biomonitors for monitoring these changes.

Summary: The study found that the decomposition rate of Eriophorum vaginatum litter was faster than that of Sphagnum, and an increase in temperature significantly promoted litter decomposition and CO2 emission for both plants. Nitrogen addition promoted the decomposition of E. vaginatum litter, but the effect on Sphagnum litter varied depending on the treatment. Microorganisms played a primary role in regulating the effects of temperature and nitrogen addition on plant litter decomposition.

Summary: This study revealed the interaction between vascular plants and climate warming and nitrogen addition in boreal peatlands. Intense competition among vascular plants exacerbated the detrimental effect of warming on Sphagnum, while facilitation by vascular plants reduced the losses of Sphagnum caused by high nitrogen addition and both warming and nitrogen addition.

Summary: This study investigates the relationship between plant tissue chemistry and soil organic matter (SOM) in an Arctic peatland, and its impact on carbon emissions. The results show that the quality of organic matter differs between different plant species and is influenced by vegetation shifts and moisture levels. The findings highlight the importance of vegetation changes in peatlands in controlling carbon emissions under climate change.
