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 …

Analysis of the One-Horned Rhinoceros (Rhinoceros Unicornis) Habitat in the Royal Chitwan National Park, Nepal.
This study analyzes the remaining suitable habitat of the one-horned rhinoceros, Rhinoceros unicornis, in Royal Chitwan National Park of Nepal. An April 2003 Landsat image was classified into eight land cover types: wetland, sand, water, mixed forest, sal forest, agriculture, settlement, and …

Assessing cumulative human impacts on northern woodland caribou with traditional ecological knowledge and resource selection functions
… positioning system collared caribou. We modeled habitat selection and assessed cumulative effects by estimating the zone of influence (ZOI) around several types of human development. At the landscape and home range scale caribou avoided the ZOI and selected pine-lichen forests in winter and …

Factors affecting distribution and habitat selection of water shrews Neomys fodiens
… is one of Britain’s least known mammals and its habitat requirements are poorly understood. The purpose of this study was to determine occurrence and associated habitat preferences of water shrews, a species of conservation concern, by comparing populations in central England freshwater habitats. …

Effects of Mid-Rotation Release on Forest Structure, Wildlife Habitat, and Pine Yield
… (Meleagris gallopavo sylvestris L.) food/brood index. Following imazapyr release, habitat suitability index (HSI) values for pine warblers (Dendroica pinus L.) and black-capped chickadees (Parus atricapillus L.) increased due to reductions in canopy hardwoods and increases in snags. Reduced …

Modeling white-tailed deer habitat quality and vegetation response to succession and management
A habitat suitability index (HSI) model for white-tailed deer (Odocoileus virginianus) was tested to determine the relationship between habitat quality predicted by the model and habitat quality suggested by the condition of 1.5 year-old bucks on Quantico Marine Corps Base, Virginia. Additionally, …

Habitat use and energetics of American black ducks wintering at Chincoteague, Virginia
The habitat use and energetics of American black ducks (Anas rubripes) wintering at Chincoteague National Wildlife Refuge, Virginia, were investigated. Twenty-two female black ducks were systematically radiotracked on the 25,600 ha study area between 15 December 1985 and 28 February 1986. Diurnal …

Isolation of the 2019 Bonnet Carré Spillway Effects on the Habitat Suitability of Brown Shrimp (Farfantepenaeus aztecus) and Blue Crab (Callinectes sapidus) Using a Modeling Approach
… and temperature depending on the age class. The Habitat Suitability Index (HSI) model framework was utilized in this study in conjunction with (1) combined-effects calculation schemes using catch per unit effort (CPUE) data and (2) hydrodynamic model (msbCOAWST) output to determine if there was a …

The ecology of the mosquito Culex modestus, a potential vector of West Nile virus in the UK
The aim of this study is to establish the habitat preferences of the mosquito Culex modestus in the UK so that its likely distribution can rapidly be determined in areas most vulnerable to West Nile Virus (WNV) becoming established in the UK. Culex modestus was first found in the North Kent marshes …

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 …

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 …

The Conservation Ecology of Rana temporaria and Bufo bufo in Leicestershire
… farming areas showed that amphibian habitat has been reduced as land use diversities, scrubs, woodland and thorn hedge cover have decreased within the previous decade. Breeding pond surveys revealed Rana temporaria to breed in areas with no rough vegetation in field ponds as small as …

Elk summer-autumn habitat selection in the Clearwater Basin of north-central Idaho
… areas. I analyzed elk detection and GIS-based habitat data from June 15-September 15 2014 to address one of the CBC's objectives: identifying elk habitat use responses on summer-autumn range. Ground-truth surveys are necessary to verify satellite-derived data are analogous to actual vegetation …

Spatio-Temporal Effects of Land Use Changes in A Savanna Wildlife Area of Kenya
… land use changes and their effects on elephant habitat quality in Amboseli Basin, Kenya. I used visual interpretation to analyze land use changes from satellite images for 1975, 1988, and 1993. I determined that during the evaluation period, conversion of areas to agricultural land has been …
