Short summary
This dataset includes monthly measurements of carbon dioxide and methane exchange between land, water, and the atmosphere from over 1,000 sites in Arctic and boreal regions. It combines measurements from a variety of ecosystems, including wetlands, forests, tundra, lakes, and rivers, gathered by over 260 researchers from 1984–2024. This dataset can be used to improve and reduce uncertainty in carbon budgets in order to strengthen our understanding of climate feedbacks in a warming world.

Thawing permafrost changes how water is stored and moves across landscapes. We measured water inputs and outputs in a basin with thawing peatland complexes and three sub-basins. In addition to yearly changes in precipitation and evapotranspiration, we found that hydrological responses are shaped by thaw-driven landscape connectivity. These findings highlight the need for long-term monitoring of ecosystem service shifts.

This study applied the CoupModel to simulate carbon dynamics and ecohydrology for a restored peatland and evaluated the responses of the simulated carbon fluxes to varying acrotelm thickness and climate. The results show that the CoupModel can simulate the coupled carbon and ecohydrology dynamics for the restored peatland system, and the restored peatland has less resilience in its C-uptake functions than pristine peatlands under a changing climate.

For the future model users, 16 peatland and wetland models reviewed to identify individual model operational scale (spatial and temporal), stabilization timeframes of different carbon pools, model specific advantages and limitations, common and specific model driving inputs, critical inputs of individual models impacting CH4 plant mediated, CH4 diffusion and CH4 ebullition. Finally, we qualitatively ranked the process representations in each model for CH4 production, oxidation and transport.

Short summary
Peatlands are among the largest carbon (C) sinks on the planet. However, peatland features such as open-water pools emit more C than they accumulate because of higher decomposition than production. With this study, we show that the rates of decomposition vary among pools and are mostly driven by the environmental conditions in pools rather than by the nature of the material being decomposed. This means that changes in pool number or size may modify the capacity of peatlands to accumulate C.

We determine the effect that duration of extraction has on CO2 and CH4 emissions from an actively extracted peatland. Peat fields had high net C emissions in the first years after opening, and these then declined to half the initial value for several decades. Findings contribute to knowledge on the atmospheric burden that results from these activities and are of use to industry in their life cycle reporting and government agencies responsible for greenhouse gas accounting and policy.

We applied CoupModel to quantify the impacts of natural and human disturbances to adjacent water bodies in regulating net CO2 uptake of northern peatlands. We found that 1 m drops of the water level at the beaver pond lower the peatland water table depth 250 m away by 0.15 m and reduce the peatland net CO2 uptake by 120 g C m-2 yr-1. Therefore, although bogs are ombrotrophic rainfed systems, the boundary hydrological conditions play an important role in regulating water storage and CO2 uptake.

Short summary
In this study, which combined a field and lab experiment with modelling, we developed a process-based model for simulating dynamics within peatland moss communities. The model is useful because Sphagnum mosses are key engineers in peatlands; their response to changes in climate via altered hydrology controls the feedback of peatland biogeochemistry to climate. Our work showed that moss capitulum traits related to water retention are the mechanism controlling moss layer dynamics in peatlands.

Short summary
Peatland respiration is made up of plant and peat sources. How to separate these sources is not well known as peat respiration is not straightforward and is more influenced by vegetation dynamics than previously thought. Results of plot level measurements from shrubs and sparse grasses in a woody bog show that plants' respiration response to changes in climate is related to their different root structures, implying a difference in the mechanisms by which they obtain water resources.
Peatland respiration is made up of plant and peat sources. How to separate these sources is not...
