Seasonal effects of plant functional groups on molecular biogeochemistry of dissolved organic matter in porewater of a poor fen Open
Climate change may transform peatlands from net carbon (C) sinks to C sources, which could result in a positive feedback to global warming. Warmer temperatures might lower water tables, increase the abundance of shrubs, slow Sphagnum and s…

Peat loss collocates with a threshold in plant–mycorrhizal associations in drained peatlands encroached by trees Open
Summary Drainage‐induced encroachment by trees may have major effects on the carbon balance of northern peatlands, and responses of microbial communities are likely to play a central mechanistic role. We profiled the soil fungal community …

The Alaska Peatland Experiment: two decades of hydrologic experiments show resilience in peatland CO2 respiration Open
Northern peatlands are experiencing some of the most rapid climate warming on the planet, which is compounded by increases in the extent and severity of climate-related disturbances such as drought, wildfire, and permafrost thaw.  Cum…

Seasonal Trends of DOM Character in Soils and Stream Change With Snowmelt Timing Open
In many watersheds, runoff occurring with snowmelt brings the largest pulse of dissolved organic matter (DOM) from soils to streams. Yet, exactly how soil and stream DOM fractions are altered as snowmelt timing changes is not well understo…

Structuring Life After Death: Plant Leachates Promote CO2 Uptake by Regulating Microbial Biofilm Interactions in a Northern Peatland Ecosystem Open
Shifts in plant functional groups associated with climate change have the potential to influence peatland carbon storage by altering the amount and composition of organic matter available to aquatic microbial biofilms. The goal of this stu…

Variation in carbon and nitrogen concentrations among peatland categories at the global scale Open
Peatlands account for 15 to 30% of the world’s soil carbon (C) stock and are important controls over global nitrogen (N) cycles. However, C and N concentrations are known to vary among peatlands contributing to the uncertainty of global C …

Evidence for older carbon loss with lowered water tables and changing plant functional groups in peatlands Open
A small imbalance in plant productivity and decomposition accounts for the carbon (C) accumulation capacity of peatlands. As climate changes, the continuity of peatland net C storage relies on rising primary production to offset increasing…

Fresh Air for the Mire-Breathing Hypothesis: Sphagnum Moss and Peat Structure Regulate the Response of CO2 Exchange to Altered Hydrology in a Northern Peatland Ecosystem Open
Sphagnum-dominated peatlands store more carbon than all of Earth’s forests, playing a large role in the balance of carbon dioxide. However, these carbon sinks face an uncertain future as the changing climate is likely to cause water stress…
