Cross-Continental Insights Into Jaguar (Panthera Onca) Ecology And Conservation, Joe Figel
Cross-Continental Insights Into Jaguar (Panthera Onca) Ecology And Conservation, Joe Figel
Electronic Theses and Dissertations
The jaguar (Panthera onca) is a widely distributed large carnivore and the focal species of a range-wide connectivity initiative known as the jaguar conservation network (JCN). Comprised of ~83 Jaguar Conservation Units (JCUs) and ~75 corridors from northern Mexico to Argentina, the JCN functions as a conduit for jaguar movement and gene flow. Key linkages in the network are imperiled by human population growth, large-scale agriculture, highway expansion, and other infrastructural development. Labeled "corridors of concern," these vulnerable linkages are imperative to the maintenance of connectivity and genetic diversity throughout jaguar distribution. I take a multi-faceted approach to analyze conservation …
Using Molecular Genetic And Demographic Tools To Improve Management Of Ex Situ Avian Populations, Gina Ferrie
Using Molecular Genetic And Demographic Tools To Improve Management Of Ex Situ Avian Populations, Gina Ferrie
Electronic Theses and Dissertations
Small populations, specifically those that are isolated from others, are more prone to extinction than larger inter-connected populations. The risks that these small isolated populations face include loss of genetic diversity due to founder effects and inbreeding due to population bottlenecks, as well as demographic uncertainty due to fluctuating fecundity and mortality rates and impacts of external environmental factors. Ex situ populations, including those managed as conservation breeding programs with species recovery aims, as well as those that do not have reintroduction goals but are managed for long term population sustainability, suffer from the same extinction risks as small and …
