The potential for adaptation in the model plant, Arabidopsis, and its close relative, Boechera
Contributor:Lovell, John Thomson
Populations of a species are found across diverse environments. Frequently, evolutionary responses to varying natural selection pressures across environments cause adaptive differentiation among populations. For plants ...
Impacts of drought on grassland productivity across the wet-dry gradient in the U.S. Great Plains in 2010-2012
Contributor:Curry, Renee A.
Severe, prolonged droughts are predicted to occur more frequently due to global climate change. Since grasslands already grow in regions that are water limited, they are particularly vulnerable to changes in precipitation. ...
The ecological legacies of drought, fire, and insect disturbance in western North American forests
Contributor:Assal, Timothy J.
Temperate forest ecosystems are subject to various disturbances including insect agents, drought and fire, which can have profound effects on the structure of the ecosystem for many years after the event. Impacts of ...
Ecological responses to climate extremes in a mesic grassland
Contributor:Hoover, David Lewis
Climate change threatens ecosystems through altered climate means and by increasing the frequency and intensity of extreme climatic events. Such events may have greater impacts on ecosystems than shifting means alone because ...
The Effects of Grasshoppers on Soil Animal Communities in the Shortgrass Steppe of Northern Colorado
Contributor:Post, Keith Harrison
A burgeoning area of research in ecology is on the linkages between aboveground and belowground components of terrestrial systems. Leaf-feeding insects can affect soil communities directly via frass deposition or indirectly ...
Maximizing the utility of available root zone soil moisture data for drought monitoring purposes in the Upper Colorado River Basin and western High Plains, and assessing the interregional importance of root zone soil moisture on warm season water balance

The timing of growing season drought and its effects on above- and belowground production in a mesic grassland
Contributor:Denton, Elsie Mariah
As a consequence of climate change, both the timing and amount of precipitation ecosystems receive are expected to be altered. In general, regions that are relatively dry are expected to get drier and the timing of seasonal ...
