Conservation genetics of Australian quolls
… quoll species. Parameters of interest to conservation were examined. Differences between translocated and endemic, island and mainland, and central and peripheral populations were also investigated. In addition, analysis of paternity was performed in a spotted-tailed quoll population. …

Conservation genetics of African elephants
… to develop and implement proactive and targeted conservation initiatives that aim at maintaining or restoring spatial and genetic connectivity between populations. In this thesis, I use a conservation genetic approach to study African elephant populations with the aim of developing methodologies …

Conservation Genetics of Gar (Atractosteus spp.)
<p>The alligator gar (<em>Atractosteus spatula</em>) is a large-bodied species of fish that historically was widely distributed in coastal drainages around the Gulf of Mexico and well north in the Mississippi River basin. Currently this species is experiencing population declines across much of its …

The conservation genetics of the Clanwilliam cedar (Widdringtonia cedarbergensis)
… and is being actively managed by Cape Nature Conservation in a small section of the Cedarberg mountains in an attempt to boost population numbers with a seedling replanting scheme and preservation of adults from fires. This study set out to determine levels of genetic diversity and fitness …

Conservation genetics of sauger in the upper Missouri River drainage
Hybridization with non-native walleye may play a substantial role in sauger declines throughout the upper Missouri River drainage of Montana and Wyoming. I identified 11 microsatellite loci to detect interspecific hybridization and describe the genetic population structure of sauger. Two major …

Conservation genetics of conflict in the Asian elephant, Elephas maximus
… of genetic tools. This dissertation uses conservation genetics to evaluate major conflict and conservation issues for Asian elephants. The first study, in the Bago Yoma region of Myanmar, evaluates the impact of direct human-conflict in a high-density area of humans and elephants. Here …

Conservation Genetics and Distribution of the Yazoo Darter (Etheostoma Raneyi)
… vulnerable or sensitive by several agencies and conservation organizations. However, the actual conservation status of this species is uncertain. Information necessary for conservation management is relatively sparse and is scattered among published and unpublished sources, particularly …

Evolutionary and conservation genetics of the Seychelles warbler (Acrocephalus sechellensis)
… I investigated how evolutionary forces and conservation action interact to shape neutral and adaptive genetic variation within and among populations. To accomplish this, I studied an island species, the Seychelles warbler (Acrocephalus sechellensis), with microsatellite markers and major …

Molecular systematics and conservation genetics of gliding petaurids (Marsupialia: petauridae).
… settlement, and most of the species are of conservation concern, either nationally or at a state level. This study applied molecular approaches to investigate several questions involving Petaurus species which may provide valuable insights for their conservation and management of species. …

Conservation genetics and population status of the Flame Chub, Hemitremia Flammea
The southeastern United States has a rich geologic history that contributed to the evolution of an extremely diverse aquatic fauna throughout the region. The Flame Chub, Hemitremia flammea, is a brightly colored, spring endemic minnow species native to the Cumberland, Tennessee, and Coosa river …

Conservation genetics of the suni antelope Nesotragus moschatus von Dueben, 1846
The suni (Nesotragus moschatus) is a very small and secretive animal distributed in the eastern parts of Africa, from Kenya south to St. Lucia in South Africa. This antelope can also be found on small islands off the Tanzanian coast. The species is a habitat specialist associated with dense …

Behavioral Ecology, Taxonomy, and Conservation Genetics of the Bahama Oriole (Icterus northropi)
… patterns of genetic variation that will inform conservation planning. The third study explored the population status and breeding ecology of the Bahama Oriole. My estimates of 141- 254 individuals remaining globally contributed to an IUCN Red List designation as "critically endangered." Orioles …

Reproductive Biology and Conservation Genetics of the Alligator Snapping Turtle (Macrochelys Temminckii)
<p>abstract: The alligator snapping turtle (Macrochelys temminckii) is a highly aquatic turtle only found in Gulf of Mexico drainages. The biology of this species remains relatively unknown, despite years of harvest and use as a zoological attraction. The purposes of this study were to (1) …

Population and Conservation Genetics of Crawfish Frogs, Lithobates areolatus, at their Northeastern Range Limits
<p>Crawfish Frogs (<italic>Lithobates areolatus</italic>) are state endangered in Indiana and Iowa, with populations in decline throughout their range. I studied populations of Crawfish Frogs on local and statewide scales at their northeastern range limits to (1) assess the level of genetic …

Conservation genetics of a spotted salamander (Ambystoma maculatum (Shaw 1802)) local population in southeast Tennessee
Currently there is a worldwide amphibian decline with numerous causes. Because of this, it is important to understand how genetic variation in local amphibian populations is affected by disturbance. The goal of this study was to assess the genetic impacts of past chemical and ammunition storage and …

The conservation genetics of a newly recognised Cape Peninsula endemic Rose's Mountain toad (Capensibufo rosei)
Declines and losses of amphibian populations are a global problem involving a complexity of interacting causes. Regardless of the fact that amphibians in Africa are among those predicted to be hit the hardest by anthropogenic global change, many species remain poorly studied. Capensibufo rosei, …

The Conservation Genetics of Two Emydid Turtles: <i>Emydoidea blandingii</i> and <i>Malaclemys terrapin</i>
<p>Conservation of turtles is complicated by their sensitivity to habitat degradation and overexploitation. I used microsatellites and standard population genetic analyses to explore genetic diversity, population structure, paternity and demographic history in two emydid turtles that are currently …
