Spatial models of metapopulations and benthic communities in patchy environments
… part, I present an analysis of the effects of habitat destruction on metapopulation persistence. Theoretical studies have already shown that a metapopulation goes extinct when the fraction of suitable patches in the landscape falls below a critical threshold (the so called extinction …

Population Size and Movements of Spotted Salamanders at South Holston Dam, Sullivan County, Tennessee.
… (<em>Ambystoma maculatum</em>) due to habitat destruction and the uncertain future of their forested riparian habitat. In this study, I establish baseline data of a population of Spotted Salamanders so future monitoring of this population can be performed. The study site is located in …

Analyzing anuran diversity in urban and rural wetlands using frog call citizen science data
… a crisis of high extinction rates because of habitat destruction, and climate change. Citizen science, the incorporation of citizens in data collection or management of scientific research, has become necessary to monitor populations widely. The Tennessee Amphibian Monitoring Program is a …

Marine alien species in Western Cape harbours, South Africa: A tool for stategically focusing monitoring efforts
… for the loss in biodiversity globally, after habitat destruction. Marine alien species are transferred across the globe through various vectors, including ballast water, hull fouling, aquaculture facilities and the aquarium and pet trade. Ballast water has previously been considered as the …

The Distribution of Genetic Variation Among Relictual Populations of Missouri Tallgrass Prairie Plants
… populations. To assess the genetic effect of habitat destruction on tallgrass prairie plant species, Wright's F-statistics were used to describe the distribution of allozyme variation among five prairie preserves in Missouri for three plant species: Schizachyrium scoparius (little bluestem), …

Reprogramming the Suburbs
… areas contribute to sprawl, car culture, habitat destruction, and other harmful social and environmental phenomena. Additionally, many of the low density urban and suburban residential neighborhoods which were developed en masse over the last century–so-called 'cookie-cutter' …

Genetic Population Structure and Effective Number of Breeders in Systems Across the Range of the Gulf Sturgeon
… reduced their range and abundance and continued habitat destruction and mortality have limited their ability to recover, leading to their listing under the Endangered Species Act. This study uses genetic techniques to determine the effective number of breeders for multiple spawning groups of Gulf …

Bald Eagle Foraging Habitats Along the James River in Missouri: Protection From Human Developments
Contamination, persecution, and habitat destruction have been responsible for the decline of bald eagles. This thesis analyzes fish samples for contaminants and uses Landsat Thematic Mapper remote sensing data to determing preferred bald eagle foraging habitats along the James River in Missouri. …

Demographic and environmental determinants of reproductive success in Synthyris bullii, a rare endemic species
In recent decades, the conversion of natural habitat to human use has proceeded at a greatly accelerated pace. This habitat destruction and degradation has resulted in the loss of much of the world's biodiversity. Some populations have been preserved in remaining habitat reserves, but their …

Biologging for marine megafauna conservation: animal tracking, environmental monitoring, and modelling approaches.
… human activities, including fishing pressure, habitat destruction, and climate change. Biologging—the use of electronic tags to study animal movement, behaviour, physiology—has emerged as a critical tool for understanding animal ecology and informing conservation strategies. This thesis …

Ecology of frontier populations of the invasive grey squirrel (Sciurus carolinensis) in Ireland
The rise in invasive species, together with habitat destruction, is associated with worldwide declines in biodiversity and ecosystem functioning. Management of invasive species, as well as amelioration of invasion impacts, provide challenges to species and ecosystem ecologists and conservation …
