Reproductive Parameters And Female Breeding Season Survival Of Rio Grande Wild Turkeys In South Central Texas, Jacob White
Reproductive Parameters And Female Breeding Season Survival Of Rio Grande Wild Turkeys In South Central Texas, Jacob White
LSU Master's Theses
Historically, Rio Grande wild turkeys in south central Texas have been at lower densities than other portions of the state. Within the Oak-Prairie Wildlife District of Texas, Rio Grande wild turkey regulatory restrictions are different for counties in the eastern and western portions of the ecoregion. Due to perceived increases in turkey density in the eastern portion of the ecoregion (hereafter 1-bird zone), Texas Parks and Wildlife Department (TPWD) considered increasing the bag limit to match counties in the western portion of the district (hereafter 4-bird zone) in order to increase hunting opportunities. However, if regulatory changes are to be …
Biogeography Of Endemic Dragonflies Of The Ozark-Ouachita Interior Highlands, Wade Alexander Boys
Biogeography Of Endemic Dragonflies Of The Ozark-Ouachita Interior Highlands, Wade Alexander Boys
Graduate Theses and Dissertations
A common pattern across many taxonomic groups is that relatively few species are widespread while the majority are restricted in their geographic ranges. Such species distributions are used to inform conservation status, which poses unique challenges for rare or cryptic species. Further, priority status is often designated within geopolitical boundaries, which may include only a portion of a species range. This, coupled with lack of distributional data, has resulted in species being designated as apparently rare throughout some portions of their range, which may not accurately reflect their overall conservation need. The Interior Highlands region of the central United States …
Improving Conservation Of Declining Young Forest Birds Through Adaptive Management, Anna Buckardt Thomas
Improving Conservation Of Declining Young Forest Birds Through Adaptive Management, Anna Buckardt Thomas
Electronic Theses and Dissertations
Early successional forest and shrubland habitats are collectively called young forest. Changes in disturbance regimes and land use conversion resulted in declines of young forest and associated wildlife across eastern North America. Conservation of declining young forest birds relies on the maintenance and creation of young forest habitats used for breeding. American Woodcock (AMWO; Scolopax minor) and Golden-winged Warbler (GWWA; Vermivora chrysoptera) are two declining young forest species. Conservation plans for both species use an adaptive management framework, which is an iterative process of planning, management actions, and monitoring and evaluation, in the context of species conservation goals. Adaptive management …
Population Health Of Spotted Salamanders (Ambystoma Maculatum) In Created Vernal Pools: An Integrative Approach, Alice R. Millikin
Population Health Of Spotted Salamanders (Ambystoma Maculatum) In Created Vernal Pools: An Integrative Approach, Alice R. Millikin
Graduate Theses, Dissertations, and Problem Reports
Habitat creation is an important tool for conservation to counteract habitat loss and degradation. Vernal pools are susceptible to destruction due to limited detection, protection, and regulation. These wetlands provide fishless breeding habitat for many amphibian species including spotted salamanders (Ambystoma maculatum) in eastern North America. Determining whether created vernal pool habitat is successful is often determined by demographic data of colonizing populations. I suggest that hormone levels, population genetics, and disease prevalence can improve our understanding of population health in created habitat. The goal of this dissertation was to assess the health of spotted salamander larvae in …
A Novel Snp Genotyping Technique To Determine Orangutan Relatedness And Genetic Diversity At Camp Leakey In Tanjung Puting, Central Kalimantan, Ruth Ella Linsky
A Novel Snp Genotyping Technique To Determine Orangutan Relatedness And Genetic Diversity At Camp Leakey In Tanjung Puting, Central Kalimantan, Ruth Ella Linsky
All Master's Theses
Genetic studies of dispersal patterns in wild populations of orangutans (Pongo spp.) have sought to confirm behavioral observations that female orangutans tend to stay near their natal range while males disperse. In order to genotype a previously unsampled wild population of endangered orangutans at Tanjung Puting National Park I developed novel application of a methyl based magnetic capture for enrichment of fecal DNA and commercial human targeted single nucleotide polymorphism (SNP) microarray technology. I confirmed results of this new genotyping technique through standard microsatellite short tandem repeat (STR) micro-capillary genotyping. I estimate genetic diversity and relatedness (r) …
