Habitat Use Of The Key Largo Woodrat (Neotoma Floridana Smalli), Lauren J. Barth Nov 2014

Habitat Use Of The Key Largo Woodrat (Neotoma Floridana Smalli), Lauren J. Barth

FIU Electronic Theses and Dissertations

Key Largo woodrats are an endangered subspecies with an extremely limited habitat. This study sought to understand woodrat habitat preferences in order to guide management. Woodrats build stick nests from natural and artificial materials, so nest distribution and nest occupancy were used as indicators of preference. Distribution was determined by nest surveys, and remote cameras were used to assess occupancy. Forest structure, human disturbance, nest, and animal presence metrics were also collected. More nests were found along abandoned roads than along forest transects and more artificial nests were occupied than natural nests. These findings indicate that woodrats prefer areas with ...

Natural Resource Ecology and Management Publications

One tool used for wildlife management is the deployment of radiocollars to gain knowledge of animal populations. Understanding the influence of individual factors (e.g., species, collar characteristics) and landscape characteristics (e.g., forested cover, shrubs, and fencing) on retention of expandable radiocollars for ungulates is important for obtaining empirical data on factors influencing ecology of young-of-the-year ungulates. During 2001–2009, we captured and radiocollared 198 white-tailed deer (Odocoileus virginianus) fawns, 142 pronghorn (Antilocapra americana) fawns, and 73 mule deer (O. hemionus) fawns in South Dakota, Minnesota, and California, USA. We documented 72 (36.4%), 8 (5.6%), and 7 ...

Syllabus: Wildlife Habitat Management, Paige Warren

Sustainability Education Resources

This course provides an in-depth exploration of wildlife-habitat relationships, illustrated through basic field zoology and natural history, evolutionary biology, and ecological theory. We introduce you to quantitative tools used to explain ecological processes and their influence on wildlife and their environment. We will examine the dynamics and management of various habitats in New England, North America, and elsewhere through field visits and use of primary literature. We will place particular emphasis on managing wildlife habitat in an urbanizing world. By one estimate, roughly 9% of the land area of the United States is in a zone of wildland-urban interface, but ...


Studies On The Ecology Of The Endangered Camaenid Land Snail Thersites Mitchellae (Cox, 1864), Jonathan Leslie Parkyn Jan 2014

Studies On The Ecology Of The Endangered Camaenid Land Snail Thersites Mitchellae (Cox, 1864), Jonathan Leslie Parkyn

Theses

Many Australian land snail species are assumed to have declined in distribution and abundance, but there are few quantitative data available to assess their conservation status. Thersites mitchellae (Cox, 1864) (Camaenidae) is listed as endangered (category ENC2a) on the IUCN 1997 Red List of Threatened Species. Population parameters such as abundance, probability of survival, and probability of site occupancy were estimated. The methods take detection probability into account and allow for the inclusion of sampling, habitat, and individual animal covariates. These models and techniques offer considerable scope for application to land snail conservation particularly for species at risk of extinction.
