A Gis-Based Habitat Model Predicting Elk Nutritional Condition in the Pacific Northwest
"Declining habitat quality has been implicated in population declines in elk (Cervus elaphus) in the Pacific Northwest (PNW) although specific causes are unknown. Nutrition and summer-autumn body condition (percent body fat) have been linked to virtually every aspect of successful ungulate …

Predictive Habitat Model for the Snapping Shrimp Genus <i>Alpheus</i> in the Coastal Southeastern United States
… develop a spatially explicit predictive model, and experimentally verify the importance of substrate as a key modeling variable through a laboratory-based substrate choice study. Significant predictor variables included in the final model for the Gulf of Mexico were Shepard code, seabed …

Developing a predictive geospatial habitat model for a rare species of salamander in Tennessee: a case study for the green salamander (Aneides aeneus)
… to detect, due to their occupation of arboreal habitats. The incorporation of geospatial tools is critical in developing models that can be used to predict undocumented locations in Tennessee and elsewhere. Locating the species in Tennessee was accomplished through a total of 18 localities and …

Mule Deer Habitat Modeling With the Use of Existing Government Data
… biologists. GIS can be used to analyze wildlife habitat. The purpose of this research was to use existing government data: Gap Analysis Project (GAP) data, Digital Elevation Model (DEM) data and Digital Line Graph (DLG) data in a GIS mule deer habitat model. The study area was the Oglala National …

Using satellite remote sensing to model and map the distribution of Bicknell's thrush (Catharus bicknelli) in the White Mountains of New Hampshire
… Thematic Mapper satellite imagery was used to model Bicknell's Thrush (Catharus bicknelli) distribution in the White Mountains of New Hampshire. The proof-of-concept was established for using satellite imagery in species-habitat modeling, where for the first time imagery spectral features were …

Essays in macroeconomics and corporate finance
… firms' ability to borrow. I develop a tractable model of deleveraging that emphasizes (i) firms as suppliers of financial assets to consumers and (ii) the ability of firms and consumers to alleviate financial frictions by accumulating wealth. In the model, a permanent decrease in the ability of …

A GIS-Based Landscape Scale Model for Native Bee Habitat
… This research explores the use of GIS in modeling native bee habitat to provide a landscape scale analysis method for native bees and develop a systematic sampling method for regional species list development. Raster GIS modeling, incorporating decision support and Poisson statistical …

LARVAL FISH EXPORT IN RESPONSE TO VARYING COMPENSATING GATE DISCHARGE AT THE SAULT RAPIDS, ST. MARYS RIVER
… 2018-2021 and compared results to published habitat model predictions. Mean discharge and water temperature were lowest in 2021 and highest in 2019. Water warming rates during high discharge differed from low discharge trends. Across years, I identified 10 families and 14 species of fish …

Habitat evaluation and production of rock bass in two Virginia streams
The use of Habitat Suitability Index (HSI) models for fisheries impact assessment has not been field validated for most fish species. This research sought to test several of the fundamental assumptions inherent in applications of Suitability Index (SI) curves with the Habitat Evaluation Procedures …

Flood Survival Strategies of Overwintering Snakes
… during hibernation and how anthropogenic habitat alteration and climate variability may affect habitat quality and overwintering survival. Chapter one reviews the current understanding of ecophysiology of hibernation in snakes. In chapter two, I introduce a winter habitat model of a …

Habitat Niche Modeling in the Texas Horned Lizard (Phrynosoma cornutum): Applications to Planned Translocation
… Oklahoma, using correlative and mechanistic habitat suitability models. My goals were broadly classified into two categories: first, to determine if the addition of mechanistic data layers (i.e., habitat-niche models) in a correlative model improved the overall accuracy of model predictions, …
