Improving state-and-transition models for management of sagebrush steppe ecosystems
Contributor:Tipton, Crystal Yates-White
The sagebrush biome was once the most widely-distributed in North America, but has recently experienced range reductions of up to 45% and has been considered one of the most endangered ecosystems in the United States (West ...
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 ...
Ecological consequences of increased nitrogen deposition in three northern Great Plains grasslands
Increased nitrogen deposition is an important driver of plant species composition change in terrestrial ecosystems globally. Plant composition change from increased nitrogen inputs can result in substantial species richness ...
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 ...
Altering water and nitrogen availability after roadside disturbance to favor native plant species
This study evaluates the use of soil amendments in roadside restoration to promote native species and discourage invasive species establishment through manipulation of water and nitrogen (N) availability. Our goal was to ...
