Habitat suitability modeling for Lontra canadensis in east Tennessee
… in effectively managing and conserving wildlife habitats. With environmental and landscape data, we can determine and assign priority areas for conservation efforts targeting the North American river otter (Lontra canadensis) in east Tennessee and beyond. The focus of the present study is the …

Incorporating microclimate into habitat suitability analysis for plethodonitd salamanders
… is important for spatially predicting suitable habitat for conservation planning. However, current approaches to modeling suitable habitat typically rely on climate data that do not account for important buffering effects of vegetation on near-surface microclimates and are produced at …

Quantifying Shoebill (Balaeniceps rex) habitat suitability in the Bangweulu Wetlands, Zambia
A quantitative analysis of suitable habitat for the Shoebill (Balaeniceps rex), a large waterbird confined to African swamps, was conducted by using a combination of aerial photographs and a previously determined habitat suitability model from the Bangweulu Wetlands, Zambia. The Shoebill is …

Assessing wildlife habitat suitability for ecological sites and state and transition models
Wildlife habitat is an important component of rangeland management plans. Unfortunately, there are few practical tools to assist managers in understanding how management and environmental variation affects habitat suitability. Ecological site descriptions (ESDs) have the potential to fill this role …

Piping plover habitat suitability on central Long Island, New York barrier islands
… quality for brood-rearing than other ocean beach habitats (intertidal zone, intertidal zone wrack, berm, berm wrack, and open vegetation). Broods with access to ephemeral pools spent more time in them, and when in them had greater foraging rates and were exposed to greater arthropod abundances …

GIS Modeling of Elk Habitat Suitability in the North Cascades of Washington State
… custom Geographic Information System (GIS) elk habitat suitability models to model baseline elk habitat suitability in the 8,600 km<sup>2</sup> North Cascades elk management area, and then evaluate how theoretical forage enhancement sites would affect habitat suitability. Prior to creating the …

An assessment of the transferability of habitat suitability criteria for smallmouth bass, Micropterus dolomieu
The purpose of this study was to determine if habitat suitability criteria developed in the summer months for sma11mouth bass were transferable among streams representing different eco regions. Habitat suitability criteria were developed for depth, mean column velocity, cover and substrate for two …

Predicting habitat suitability for American woodcock and landscape-level assessment of habitat in West Virginia
… were to (1) develop models to predict potential habitat suitability for woodcock over large geographic areas in West Virginia (Chapter 4), (2) quantify and describe the local and landscape structural components and spatial patterns of woodcock habitat in the state (Chapter 3), and (3) to …

An Assessment of Habitat Suitability for Pronghorn Populations of the Central Valley Region of California
… isopleth was used to define “used” and “unused” habitat areas within the study site. Binary logistic regression was used to detect correlations between habitat variables and habitat use by pronghorn. Results of the regression analysis indicated overall significance with a p-value of < 0.0001 …

Developing Habitat Suitability Criteria for Individual Species and Habitat Guilds in the Shenandoah River Basin
… An often-suggested approach has been to use habitat guilds to incorporate the diversity found in these systems. My goal is to determine the feasibility of developing habitat suitability criteria (HSC) for the entire fish assemblage in the North and South Fork Shenandoah River, Virginia, using …

Habitat suitability and population characteristics of smallmouth bass and rock bass in the Powell River, Virginia
… rock bass (Ambloplites rupestris), and habitat conditions were conducted in the Powell River, Virginia, to identify potential habitat limitations for these species. The study area consisted of three reaches, which were determined in 1987. The upstream reach was used to monitor effects of …

The Effect of Seasonal Vegetation Changes on Habitat Suitability and Predation Risk of the Vancouver Island Marmot
… Island, Canada, but will also colonize logged habitats at lower elevations, which become population sinks for the species. Tree encroachment and vegetation shifts in these habitats are likely affecting seasonal vegetation cover and reducing the ability of marmots to visually detect predators, …

Field evaluation of the northern bobwhite habitat suitability index model with implications for the conservation reserve program
… of the northern bobwhite (Colinus virginianus) Habitat Suitability Index (HSI) model was conducted using habitat and relative abundance data from 121 sites distributed throughout Halifax County, Virginia, 1986-1991. Model output and the index of relative abundance were only poorly correlated …

State-wide assessment of status, predicted distribution, and landscape-level habitat suitability of amphibians and reptiles in Montana
… modeling to predict state-wide distribution and habitat suitability for all of Montana's amphibians and reptiles. These models out performed GAP analysis models by simultaneously reducing the area predicted and omission error rates. Among other things, models identified scale dependent responses …

A Mechanistic and Landscape Scale Approach Quantifying Habitat Suitability of Cheatgrass (Bromus tectorum) Engineered Habitats for Great Basin Reptiles
… In the Great Basin Desert of North America, habitat degradation has led to widespread invasion by a highly successful plant species, cheatgrass (Bromus tectorum). The result has been the alteration of landscape structure and ecosystem function. This novel habitat has been implicated in …

Propagation of Juvenile Freshwater Mussels (Bivalvia: Unionidae) and Assessment of Habitat Suitability for Restoration of Mussels in the Clinch River, Virginia
… of three experiments. Experiment 1 tested the suitability of a pond and raceway for rearing juvenile oystermussels (Epioblasma capsaeformis) and wavyrayed lampmussel (Lampsilis fasciola). This experiment was prematurely terminated due to predation on mussels by fathead minnows (Pimephales …
