Simulation-Based Spatially Explicit Close-Kin Mark-Recapture for Genetic Monitoring of Wildlife Populations
… simulations. When tested on simulated populations, the method is able to accurately estimate population size from parent-offspring and half-sibling pairs, even when dispersal is limited and some areas of the landscape are more intensely sampled than others, a situation in which …

Blood urea nitrogen levels of white-tailed deer as an index of condition and nutritional intake
The classical objective of wildlife managers is to provide the public with the maximum number of hours of outdoor recreation by means of the wildlife resource without impairing that resource for future use. A biologist is continually concerned with the deterioration of wildlife populations and …

Spatial capture-recapture for acoustic surveys
… one method to estimate the animal density of a wildlife population, where animal density describes the number of animals per unit area within the survey region. Since SCR’s inception, it has seen increasing use in estimating animal density from data collected by non-invasive sampling methods …

Monitoring and Conserving Wildlife Communities across Northern Botswana
… Botswana, where knowledge of many of the diverse wildlife populations is lacking. To address this knowledge gap, my dissertation research evaluated the distributions, densities, and ecology of the wildlife community in northern Botswana, with a focus on terrestrial carnivore species given their …

Tracking Pathogen Transmission at the Human-Wildlife Interface: Banded Mongoose (Mungos mungo) and Escherichia coli as a Model System in Chobe, Botswana
… caused by pathogens transmitted from humans to wildlife, pose a significant health threat to wildlife populations. Many of these pathogens are also able to move from wildlife reservoirs to humans, termed zoonotic diseases, creating the possibility for bi-directional transmission between humans …

Public preferences for nongame wildlife programs in Virginia
Attitudes of Virginia citizens toward wildlife management programs were studied using a survey questionnaire mailed to 2,000 randomly selected households. The response rate was 56%. Wildlife's ecological, viewing, cultural, existence, and scientific benefits were valued by most of the respondents …

Woody vegetation change in response to browsing in Ithala Game Reserve, South Africa
Wildlife populations in southern Africa are increasingly forced into smaller areas by the demand for agricultural and residential land, and many are now restricted by protective fences. Although numerous studies have focused on the impacts of elephants and other browsers on vegetation in large, …

Understanding animal movements to inform bovine tuberculosis surveillance: a framework for a targeted approach
… is a zoonotic disease that affects domestic and wildlife species. In recent years in the US, a novel scenario for bTB has arisen, characterized by sporadic outbreaks in cattle populations across the country and by spillover of the infection to wildlife. The cattle production system in the US …

Sentience and Site
… a US Forest Service outpost monitoring changing wildlife populations and behaviors within the George Washington and Jefferson National Forests. Dubbed The Aviary, the construct functions as a wilderness drone-port, supporting a large, integrated network of conservation-drone activity over the …

An enquiry into gamefarming in the Cape Province
… potential biological productivity of indigenous wildlife populations. This study enquired as to the reasons for such failure within the Cape Province. The enquiry focused on management, research and marketing aspects of gamefarming. Personal interviews, a questionnaire and a literature analysis …

Using spatial methods to analyse anthropogenic predation risk and movement ecology of white-tailed deer (Odocoileus virginianus)
Hunting has been used as a central tool by wildlife managers to maintain populations of game species, however, we still lack a good understanding of exactly how hunting influences deer biology. Technological advances in GPS data over the last two decades now enable us to perform more detailed …

The effects of urbanization on winter avian diversity: a citizen science and GIS study
… to urban expansion is inevitable, affecting many wildlife species. Birds have become a frequently used model species for studying the effects of urbanization on wildlife populations due to their environmental sensitivity and ease of observation. While previous studies have investigated changes in …

Climate Adaptation and Local Narratives: Using qualitative inquiry to inform adaptive management on the North Shore of Lake Superior Minnesota, USA
… the attribution of changes in forest health and wildlife populations to climate change, but divergence around when to be concerned for local impacts. Findings indicate the need to ground local adaptation in observable changes, and the importance of facilitating stakeholder engagement with the …

Availability of Organochlorides and Accumulation in Populations of Tadarida brasiliensis (Free-Tailed Bat) and Eptesicus fuscus (Big Brown Bat)
… Due to these problems, especially declines in wildlife populations, organochlorides were restricted in the 1970's and a majority of them were banned in the mid to late 1980's. The effects of organochlorides on bats such as Tadarida brasiliensis and Eptesicus fuscus have been intensively …

A computer model of wildlife rabies epizootics and an analysis of incidence patterns
… the characteristics of rabies epizootics in wildlife populations. Initial analysis of temporal and spatial relationships between reported rabies cases in four ecologically divergent counties was conducted. No single pattern of report incidence was found to be characteristic of all counties. …

Population Genetic Structure of Unionid Mussels Across Multiple Gulf Drainages
… of genetic differentiation within and across wildlife populations is a key component to parsing the demographic and ecological processes that govern the spatial structure and evolutionary trends of a given species. As molecular and computational techniques continue to advance, these data have …

Ecological indicators of access and access management : a wildlife perspective
… growing concern that human access into areas of wildlife habitat and the management of that access has become one of the most significant issues in sustaining wildlife populations worldwide. Although access management is recommended throughout primary wildlife research and provincial land …

An Analysis of Illegal Bushmeat Availability in Local Restaurants Located in Voi, Kenya
… has been identified as a reason for declining wildlife populations throughout much of Africa. For many years the trade was thought to exist primarily in Western Africa. The illegal use of bushmeat in Eastern Africa, including Kenya, went undocumented and unstudied. In 2004, the Born Free …
