Integrating Remote Sensing And Ecosystem Models For Terrestrial Vegetation Analysis: Phenology, Biomass, And Stand Age, Gong Zhang
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Terrestrial vegetation plays an important role in global carbon cycling and climate change by assimilating carbon into biomass during the growing season and releasing it due to natural or anthropogenic disturbances. Remote sensing and ecosystem models can help us extend our studies of vegetation phenology, aboveground biomass, and disturbances from field sites to regional or global scales. Nonetheless, remote sensing-derived variables may differ in fundamental and important ways from ground measurements. With the growth of remote sensing as a key tool in geoscience research, comparisons to ground data and intercomparisons among satellite products are needed. Here I conduct three separate …
Homogenization Of Large-Scale Movement Models In Ecology With Application To The Spread Of Chronic Wasting Disease In Mule Deer, Martha J. Garlick
Homogenization Of Large-Scale Movement Models In Ecology With Application To The Spread Of Chronic Wasting Disease In Mule Deer, Martha J. Garlick
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy (TSE) that affects deer, elk, and moose. TSEs are prion diseases which include mad cow disease and scrapie in sheep and goats. The disease agent is a misshapen protein called a prion, which causes lesions in the brain, and to date, there is no cure. CWD is a slow-developing, fatal disease, which is rare in the free-ranging mule deer population of Utah. Infected deer shed prions into the environment through saliva, feces, and decaying carcasses. These prions remain infective in soils for many years and healthy deer may contract CWD by …
