Surveys Of Aphonopelma Hentzi In Missouri: Conservation Efforts Through Population, Genetics, And Habitat Studies, Anderson B. Spencer Mr., Becky Hansis-O'Niell Jan 2024

Surveys Of Aphonopelma Hentzi In Missouri: Conservation Efforts Through Population, Genetics, And Habitat Studies, Anderson B. Spencer Mr., Becky Hansis-O'Niell

Undergraduate Research Symposium

Aphonopelma hentzi and other tarantula species are greatly understudied organisms. In the Missouri regions there is little knowledge on their mating patterns, gene diversity, or population sizes. The focal glades in this experiment display regional fragmentation, which could prevent tarantulas from traveling and mating between regions of their glades. Due to the lack of knowledge surrounding them, methods for determining gene diversity are harmful to the organism. Our recent work has shown that it is possible to extract genetic information from the molts of burrowing tarantulas. This will allow us to safely determine the lineages and interbreeding patterns of the …


Conservation Status Assessment Of The Egg-Mimic Darter (Percidae: Etheostoma Pseudovulatum) Using A Multi-Faceted Approach, Zachary L. Wolf, John W. Johansen, Rebecca E. Blanton Mar 2022

Conservation Status Assessment Of The Egg-Mimic Darter (Percidae: Etheostoma Pseudovulatum) Using A Multi-Faceted Approach, Zachary L. Wolf, John W. Johansen, Rebecca E. Blanton

Southeastern Fishes Council Proceedings

The imperiled Egg-mimic Darter (Etheostoma pseudovulatum) is a headwater-adapted fish restricted to an area less than 1000 km2 in Tennessee. It is found in only six tributaries of the Duck River and the large, mainstem of this system may act as a barrier to dispersal, restricting population connectivity. The only status assessment of this species was over two decades ago; genetic diversity and the degree of population connectivity have never been evaluated. We conducted a conservation status assessment using a multi-faceted approach to better inform conservation management plans, including examining its current distribution, assessing habitat quality, estimating …


Rescue And Reestablishment Of Chicken Models For Spontaneously Occurring Hashimoto’S Thyroiditis And Systemic Sclerosis/Scleroderma, Joseph Zolton Hiltz Aug 2019

Rescue And Reestablishment Of Chicken Models For Spontaneously Occurring Hashimoto’S Thyroiditis And Systemic Sclerosis/Scleroderma, Joseph Zolton Hiltz

Graduate Theses and Dissertations

The loss of biodiversity is a topic gaining popularity both in the political and scientific forums. Nearly 30 years ago researchers and politicians congregated in Rio de Janeiro (1992) to attend the first Earth Summit. It was the first meeting of its kind discussing the tangible pressing consequences of biodiversity loss as well as the potential long term ramifications. Many of the countries represented at this summit implemented short and long term plans in order to accurately measure losses of biodiversity as well as establishing organizations to help diagnose and remedy the current problems at hand. These new organizations and …


Iron Metabolism Genes In Browsing And Grazing Rhinoceroses: Implications For Iron Overload Disorder, Lorien Salyer Jan 2017

Iron Metabolism Genes In Browsing And Grazing Rhinoceroses: Implications For Iron Overload Disorder, Lorien Salyer

Undergraduate Honors Thesis Projects

Iron overload disorder is a serious condition that affects many animals of conservation interest, including rhinoceroses. Iron overload disorder is only found in browsing rhinos (African black, Diceros bicornis, and Sumatran, Dicerorhinus sumatrensis) but not in grazing species (African white, Ceratotherium simum, and greater one-horned, Rhinoceros unicornis). Iron overload is connected with many of the other health issues seen in captive browsing rhinoceroses, so it is vitally important that the iron metabolism process is studied to improve the existing husbandry procedures of these critically endangered animals. The objective of this study was to characterize genes related to …
