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 …

Ecological scale and species-habitat modeling: studies on the Northern flying squirrel.
… nature of wildlife populations, species-habitat modeling is a field in which much proliferation of multi-scale studies has occurred, and thus provides a good arena within which to test both scale theory and its application. Insufficient examination of a relevant breadth of the scale …

Management Planning and Habitat Modeling for Wild Turkeys (Meleagris Gallopavo Silvestris) in Virginia
… and had no modern means to assess turkey habitat. My objectives were to (1) identify stakeholders in management of wild turkeys in Virginia, assess their attitudes and opinions regarding turkey management, and incorporate that knowledge in developing a management plan for wild turkeys in …

Habitat Modeling of Three Endemic Crayfish Species in the Black River Drainage of Missouri and Arkansas: Factors Affecting Distribution and Abundance
… three drainages. The models were effective in modeling rare crayfish species and the results were consistent with previous observations of the three species. Conservation attention may be necessary to protect groundwater resources and to safeguard against further invasions of O. neglectus.</p>

Habitat Suitability and Availability for Rainbow Trout (Oncorhynchus mykiss) in the Canyon Reservoir Tailrace and Evaluation of Side Scan Sonar for Habitat Mapping in a Semi-Wadable River
… the southeastern United States to mitigate fish habitat and assemblage alterations caused by large impoundments. Hypolimnetic discharges from Canyon Reservoir have created conditions suitable for a coldwater tailrace fishery and trout have been stocked there since 1966. Changes in habitat …

Controls over the distribution of soil micro-invertebrates in the McMurdo Dry Valleys, Antarctica
… I combine long-term ecological data with spatial habitat modeling to investigate the environmental drivers of micro-invertebrate distributions and predict future distributions under variations in moisture availability associated with shifting climate regimes. Chapter 1 documents the creation and …

A SIMPLE GIS APPROACH TO PREDICTING RARE PLANT HABITAT: NORTH CENTRAL ROCKY MOUNTAINS, UNITED STATES FOREST SERVICE, REGION ONE
… and regulating land-use activities. Predictive modeling of plant distributions rests on the assumption that correlations exist between the presence or absence of a species and selected climate, topographic, substrate, and land-cover variables. Using the DOMAIN algorithm along with Geographic …

Nesting in the Clouds: Evaluating and Predicting Sea Turtle Nesting Beach Parameters from Lidar Data
… image spatial resolution, particularly for habitat modeling. For habitat-specialized species, such data may not be sufficient to successfully capture the nuances of their preferred areas. Of particular concern are those species for which topographic feature attributes are a main limiting …

Using satellite remote sensing to model and map the distribution of Bicknell's thrush (Catharus bicknelli) in the White Mountains of New Hampshire
… for using satellite imagery in species-habitat modeling, where for the first time imagery spectral features were used to estimate a species-habitat model variable. The model predicted rising probabilities of thrush presence with decreasing dominant vegetation height, increasing …

Using a multi-dimensional approach to determine the conservation and taxonomic statuses of two rare crayfishes in northern Arkansas
… of this study, we utilized species distribution modeling (SDM) using the program MaxEnt and fine scale habitat modeling to analyze the distribution and habitat preferences of C. causeyi. Our SDM found average annual precipitation was by far the most important predictor of C. causeyi relative …

Building a Predictive Model of Delmarva Fox Squirrel (Sciurus niger cinereus) Occurrence Using Infrared Photomonitors
Habitat modeling can assist in managing potentially widespread but poorly known biological resources such as the federally endangered Delmarva fox squirrel (DFS; Sciurus niger cinereus). The ability to predict or identify suitable habitat is a necessary component of this species' recovery. Habitat …

THE INFLUENCE OF ENVIRONMENTAL VARIABLES ON PREDICTING RARE-PLANT HABITAT IN THE NEZ PERCE NATIONAL FOREST
<p>Habitat suitability modeling is widely-used in both biogeography and ecology to characterize the biophysical requirements and distribution of plant and animal species. Many of these modeling efforts use different variants of essentially the same topo-climatic variables (elevation, slope, aspect, …
