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 …
Extreme drought or wet conditions have now been found to strongly influence the vegetative development of ecosystems. Semi-arid regions are most affected - raising concerns about their vulnerability to long-term drought in the future. © 2015 …
The respiratory release of carbon dioxide (CO2) from the land surface is a major flux in the global carbon cycle, antipodal to photosynthetic CO2 uptake. Understanding the sensitivity of respiratory processes to temperature is central for quantifying …
