Relationship Between Food Intake And Expression Of O-Linked N-Acetylglucosamine Transferase Messenger Rna In Channel Catfish, Oaklee Abernathy
Relationship Between Food Intake And Expression Of O-Linked N-Acetylglucosamine Transferase Messenger Rna In Channel Catfish, Oaklee Abernathy
Master's Theses
Food intake regulation is a complex neural process that involves the coordination of multiple mechanisms. O-linked N-acetylglucosamine transferase (OGT) is a neural nutrient sensor that aids in regulating satiety in mammals. Compared to mammals, little is known about function and regulation of OGT expression in fish. It was hypothesized changes in food intake are associated with changes in OGT expression in channel catfish. The objectives of this study were to examine tissue distribution of OGT mRNA and determine the possible relationship between food intake and OGT mRNA in channel catfish. Screening of the catfish genome database yielded four highly homologous …

Spatial Ecology Of The Western Massasauga (Sisturus Tergeminus) In A Large Interior Wetland, Joshua Mead
Spatial Ecology Of The Western Massasauga (Sisturus Tergeminus) In A Large Interior Wetland, Joshua Mead
Master's Theses
Insight into the spatial ecology of a population of animals provides information valuable to the management and conservation of a species. Reptiles are facing global declines, with 1 in 5 species currently threatened with extinction. For cryptic taxa such as snakes, radio-telemetry allows for individuals to be reliably located on a consistent basis. I used radio-telemetry to investigate the spatial ecology of the Western Massasauga (Sistrurus tergeminus) at Cheyenne Bottoms in Barton County, Kansas. Eighteen individuals (12 male and 6 female) were implanted with very high frequency (VHF) radio transmitters during 2016-2017 and tracked twice weekly from July to November …
An Aerial Perspective: Using Unmanned Aerial Systems To Predict Presence Of Lesser Earless Lizards (Holbrookia Maculata), Sean Rogers
Master's Theses
Implementation of unmanned aerial system (UAS) in conservation biology has allowed researchers to extend their surveying range for monitoring wildlife. Wildlife biologists have started using UAS technology for detecting large species (i.e. elk, manatees) within their surveying range and monitoring changes and disturbance in the landscape. Despite this technological advancement, there are few studies that target smaller species (reptiles, rodents, amphibians) for UAS surveys. The primary reason for this is that these organisms are simply too small for detection for aerial surveying. However, certain species are restricted in their range because they have specific environmental requirements, and the target for …
An Evaluation Of Trap-Neuter-Release Practices For Free-Roaming Cat Populations, Brian Gaston
An Evaluation Of Trap-Neuter-Release Practices For Free-Roaming Cat Populations, Brian Gaston
Master's Theses
As of 2002, estimates of free-roaming domestic cat (Felis catus) populations exceeded 100 million individuals, throughout the United States. Many lost or abandoned cats will revert to living outdoors as free-roaming individuals. To try to control the abundance of free-roaming cats, trap-neuter-release (TNR) programs have been implemented across the United States. The goal of many TNR programs is to reduce cat populations by sterilizing the individuals to prevent breeding, while also providing food and water to the unconfined colony. However, wildlife conservationists question the effectiveness of TNR programs. The objectives of my study were to: determine the population size and …

Incorporating Multi-Spectral Imaging Into Long-Term Upland Breeding Bird Monitoring, Kyle William Schumacher
Master's Theses
Quivira National Wildlife Refuge in Kansas, United States partnered with Fort Hays State University Hays, KS in 2014 to begin a collaborative research project that aimed to develop a long-term monitoring protocol guided by the Comprehensive Conservation Plan for the refuge published in 2013. This plan identified specific wildlife taxa underrepresented in management impact assessments throughout the property. As a result of this plan, surveys were established to monitor interactions between upland breeding birds and the vegetation community. I conducted point count surveys in 2016, 2017, and 2018 for 122 observation points across four transects. I measured seventeen vegetation variables …
Distribution Of Porcine Endogenous Retrovirus (Perv) Variants In Domestic And Feral Pig, Rashmi Acharya
Distribution Of Porcine Endogenous Retrovirus (Perv) Variants In Domestic And Feral Pig, Rashmi Acharya
Master's Theses
Xenotransplantation is considered an alternative to allotransplantation to relieve the current shortage of human organs. Due to their similar size and physiology, the organs of pigs are of particular interest for this purpose. Endogenous retroviruses are a result of integration of retroviral genomes into the genome of infected germ cells as DNA copies (proviruses), which are then carried in all cells of the offspring of the organism. Porcine Endogenous Retroviruses (PERVs) are of special concern because they are found in pig organs and tissue that might be used for xenotransplantation. PERV proviruses, already incorporated into the pig’s genome, can be …
Identification And Characterization Of Tri-Colored Bat Hibernaculum In Russell County, Kansas, Angelica Sprague
Identification And Characterization Of Tri-Colored Bat Hibernaculum In Russell County, Kansas, Angelica Sprague
Master's Theses
Caves are often essential during hibernation, a sensitive stage in the life cycle of bats. Caves offer more stable conditions, such as temperature and relative humidity, during the changing seasons when food supply is limited, and weather is unstable. As caves in North-Central Kansas are sparse, the hibernating status of tri-colored bat (Perimyotis subflavus) is not well known. Bats are experiencing substantial population declines within the United States, caused primarily by white nose-syndrome, as well as habitat loss and degradation, and increased wind-power facilities. In the winter seasons of 2015 and 2016, I studied tri-colored bat hibernacula. A man-made “cave” …
