Soil bacterial community composition altered by increased nutrient availability in Arctic tundra soils
Author(s):Koyama, Akihiro; Wallenstein, Matthew D.; Simpson, Rodney T.; Moore, John C.
The pool of soil organic carbon (SOC) in the Arctic is disproportionally large compared to those in other biomes. This large quantity of SOC accumulated over millennia due to slow rates of decomposition relative to net ...
Microbial responses to multi-factor climate change: effects on soil enzymes
Author(s):Steinweg, J. Megan; Dukes, Jeffery S.; Paul, Eldor A.; Wallenstein, Matthew D.
The activities of extracellular enzymes, the proximate agents of decomposition in soils, are known to depend strongly on temperature, but less is known about how they respond to changes in precipitation patterns, and the ...
