Nest-site selection and breeding success of passerines in the world’s southernmost forests
This article studies the nest-site selection and survival rate of the five most abundant open-cup forest-dwelling passerines (Elaenia albiceps, Zonotrichia capensis, Phrygilus patagonicus, Turdus falcklandii, and Anairetes parulus) in the world’s southernmost forests of Navarino Island, in the Cape Horn Biosphere reserve, Chile (55°S).

Use of geographic information systems and infrared-triggered cameras to assess white-tailed deer (Odocoileus virginianus) habitat in Denton County, Texas.
This study utilized geographic information systems, remote sensing, and infrared-triggered cameras to assess white-tailed deer habitat in Denton County, Texas. Denton County is experiencing tremendous growth in both population and development. Despite their presence here historically, white-tailed deer were all but extirpated by the beginning of the 20th century, and there are no data available which support their presence in Denton County again until the 1980's. This study attempts to equate the increase in white-tailed deer population to Denton County's transformation from an agricultural to an urban economy and lifestyle. Eighteen sites were chosen throughout the county to research the following metrics: geology, soils, landcover, landscape ecology, streams, shorelines, land use, population, roads, structures, and census methods.

Albeni Falls Wildlife Protection, Mitigation, and Enhancement Plan, Final Report 1987.
A wildlife impact assessment and mitigation plan has been developed for the US Army Corps of Engineers Albeni Falls Project in northern Idaho. The Habitat Evaluation Procedure (HEP) was used to evaluate pre- and post-construction habitat conditions at the Albeni Falls Project. There were 6617 acres of wetlands converted to open water due to development and operation of the project. Eight evaluation species were selected with impacts expressed in numbers of Habitat Units (HU's). For a given species, one HU is equivalent to one acre of prime habitat. The Albeni Falls Project resulted in estimated losses of 5985 mallard HU's, 4699 Canada goose HU's, 3379 redhead HU's, 4508 breeding bald eagle HU's, 4365 wintering bald eagle HU's, 2286 black-capped chickadee HU's, 1680 white-tailed deer HU's, and 1756 muskrat HU's. The yellow warbler gained 71 HU's. Therefore, total target species estimated impacts were 28,587 HU's. Impacts on peregrine falcons were not quantified in terms of HU's. Projects have been proposed by an interagency team of biologists to mitigate the impacts of Albeni Falls on wildlife. The HEP was used to estimate benefits of proposed mitigation projects to target species. Through a series of proposed protection and enhancement actions, the mitigation plan …

Thermal Identification of Clandestine Burials: A Signature Analysis and Image Classification Approach
Clandestine burials, the interred human remains of forensic interest, are generally small features located in isolated environments. Typical ground searches can be both time-consuming and dangerous. Thermal remote sensing has been recognized for some time as a possible search strategy for such burials that are in relatively open areas; however, there is a paucity of published research with respect to this application. This project involved image manipulation, the analyses of signatures for "graves" of various depths when compared to an undisturbed background, and the use of image classification techniques to tease out these features. This research demonstrates a relationship between the depth of burial disturbance and the resultant signature. Further, image classification techniques, especially object-oriented algorithms, can be successfully applied to single band thermal imagery. These findings may ultimately decrease burial search times for law enforcement and increase the likelihood of locating clandestine graves.

South Oak Cliff (SOC-3) Blue Line Extension in Dallas County, Texas: Final Local Environmental Assessment
This Local Environmental Assessment (LEA) describes the transportation and environmental impacts associated with the construction and operation of a proposed, 2.6-mile light rail extension from Ledbetter Station to the UNT Dallas campus and identifies mitigation measures. This Final LEA is based on the 5% level of design and includes responses to comments received during the 30-day public review period for the Draft LEA.

Habitat Fragmentation by Land-Use Change: One-Horned Rhinoceros in Nepal and Red-Cockaded Woodpecker in Texas
This research focuses on the spatial analysis of the habitat of two vulnerable species, the one-horn rhinoceros in the grasslands of southern Nepal, and the red-cockaded woodpecker in the Piney woods of southeast Texas, in the USA. A study sites relevant for biodiversity conservation was selected in each country: Chitwan National Park in Nepal, and areas near the Big Thicket National Preserve in Texas. Land-use differs in the two study areas: the first is still undergoing agrarian development while the second is in a technological phase and undergoing urbanization processes. Satellite remote sensing images were used to derive land-cover maps by supervised classification. These maps were then processed by Geographic Information Systems methods to apply habitat models based on basic resources (food and cover) and obtain habitat suitability maps. Several landscape metrics were computed to quantify the habitat characteristics especially the composition and configuration of suitable habitat patches. Sensitivity analyses were performed as the nominal values of some of the model parameters were arbitrary. Development potential probability models were used to hypothesize changes in land-use of the second study site. Various scenarios were employed to examine the impact of development on the habitat of red-cockaded woodpecker. The method derived in …

Determining the Suitability of Functional Landscapes and Wildlife Corridors Utilizing Conservation GIS Methods in Denton County, Texas.
Denton County's unique cultural and natural landscape has undergone dramatic transformations during the past two centuries due to agricultural, urban and suburban processes which accelerated the loss and removal of native habitat and wildlife. This research sought out to identify the remaining natural areas which retain their natural features and support wildlife. Research methodology included fundamental principles of Conservation Planning, Geographical Information Systems, and Habitat Evaluation Procedures for identifying remnant functional landscapes and wildlife corridors. The final results suggest that Denton County's rural landscape retains the functional properties and elements suitable for habitat conservation and wildlife corridors, while also pointing to the fundamental obstacles to conservation posed by continued growth and private landownership.
