Abstract

Elevated greenhouse gas (GHG) emissions, particularly of methane (CH4) from flooded rice production systems contribute to global warming. Different crop management strategies, such as drainage of paddy soils and climate-smart residue management, are essential in order to mitigate GHG emissions from ...

Abstract

Expected climate change in high latitudes includes increased air temperature, precipitation, and humidity in the coming decades. Simultaneously, climate extremes like heat waves and droughts become more frequent. In the Free-Air Humidity Manipulation (FAHM) experiment in silver birch (Betula...

Abstract

Regional quantification of soil CO2 and CH4 fluxes in boreal forests remains difficult because of high landscape heterogeneity and fire disturbance coupled with a sparse measurements network. Most of the work focuses on the separate effects of fire or topography, and as a result, the spatial...

Abstract

Agriculture and land use change has significantly increased atmospheric emissions of the non-CO2 green-house gases (GHG) nitrous oxide (N2O) and methane (CH4). Since human nutritional and bioenergy needs continue to increase, at a shrinking global land area for production, novel land management...

Abstract

Rich fens are common boreal ecosystems with distinct hydrology, biogeochemistry and ecology that influence their carbon (C) balance. We present growing season soil chamber methane emission (FCH4), ecosystem respiration (ER), net ecosystem exchange (NEE) and gross primary production (GPP) fluxes...

Abstract

At the southern margin of permafrost in North America, climate change causes widespread permafrost thaw. In boreal lowlands, thawing forested permafrost peat plateaus ('forest') lead to expansion of permafrost-free wetlands ('wetland'). Expanding wetland area with saturated and warmer organic soils ...

Abstract

As surface temperatures are expected to rise in the future, ice-rich permafrost may thaw, altering soil topography and hydrology and creating a mosaic of wet and dry soil surfaces in the Arctic. Arctic wetlands are large sources of CH4, and investigating effects of soil hydrology on CH4 fluxes is...

Abstract

Increasing salinity due to sea level rise is an important factor influencing biogeochemical processes in estuarine wetlands, with the potential to impact greenhouse gas (GHG) emissions. However, there is little consensus regarding what salinity thresholds will significantly alter the production of...

Abstract

Boreal wetlands are significant natural sources of methane (CH4) to the atmosphere, and are vulnerable to freezing-thawing cycles (FTC). Nonetheless, the underlying factors that induce CH4 emission in boreal wetlands during FTC are still unclear. Our goal was to characterize soil CH4 emission...

Abstract

Purpose: Understanding the effects of temperature and moisture on soil organic carbon (SOC) dynamics is crucial to predict the cycling of C in terrestrial ecosystems under a changing climate. For single rice cropping system, there are two contrasting phases of SOC decomposition in rice paddy soils: ...
