Interactions between individual plant species and soil nutrient status in shortgrass steppe
Contributor:Burke, Ingrid C.; Vinton, Amry Ann
The effect of plant community structure on nutrient cycling is fundamental to our understanding of ecosystem function. We examined the importance of plant species and plant cover (i.e., plant covered microsites vs. bare ...
Microbial responses to multi-factor climate change : effects on soil enzymes
Contributor: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 ...
Restoring carbon accumulating processes in a degraded wet meadow
Wet meadows throughout the Sierra Nevada range of western North America were historically disturbed and are thought to be losing soil water holding capacity and the ability to store carbon (C). I tested whether herbivore ...
Microbial and biogeochemical responses to changing precipitation patterns in grassland ecosystems
Contributor:Evans, Sarah E.
Global circulation models predict that precipitation patterns in grasslands will both intensify and be characterized by more severe drought in the future. In these systems, the availability of water strongly controls ...
What happens during soil incubations? : exploring microbial biomass, carbon availability and temperature constraints on soil respiration
Contributor:Birgé, Hannah E.
Decomposition of soil organic matter (SOM) is one of earth's most important and dynamic biogeochemical cycles. Much research is devoted to separating and studying individual controls on SOM decomposition. A commonly-used ...
