Evaluating The Social Behavior And Activity Patterns Of Clouded Leopards (Neofelis Nebulosa) At The Nashville Zoo: Research And Literature Review, Meghan Ryckeley
Evaluating The Social Behavior And Activity Patterns Of Clouded Leopards (Neofelis Nebulosa) At The Nashville Zoo: Research And Literature Review, Meghan Ryckeley
Mahurin Honors College Capstone Experience/Thesis Projects
The behavior of the elusive clouded leopard (Neofelis nebulosa) is not well understood. In captivity, they are prone to exhibit stress-related behaviors and are often aggressive to conspecifics when paired. The present study built on past research by examining clouded leopards at the Nashville Zoo at Grassmere (NZG) to determine their activity patterns and temperament. Twelve leopards were exposed to familiar and unfamiliar objects and people, as well as their reflection in a mirror over nine trials. The males were often more reactive than the females, and the 5-year olds more reactive than their younger counterparts. The mirror …
Finding A Link Between Circadian Rhythms And The Immune System Of Captive Zebra Finches (Taeniopygia Guttata), Amber Bishop
Finding A Link Between Circadian Rhythms And The Immune System Of Captive Zebra Finches (Taeniopygia Guttata), Amber Bishop
Mahurin Honors College Capstone Experience/Thesis Projects
Circadian rhythms are commonplace in organisms and are normally controlled by a master clock. More recent evidence suggests that autonomous clocks operate in various systems in the body, including the immune system. This study looks for such a connection between the circadian rhythm and the immune system. In this study, captive zebra finches (Taeniopygia guttata) were exposed to different light and dark cycles and blood samples were taken every six hours. Birds were exposed to 12 hours of light and then 12 hours of darkness (LD), 24 hours of darkness (DD), or 48 hours of DD. After collecting …

Analysis Of Population Structure In A California Newt (Taricha Torosa) Metapopulation, Jessica Vincent
Mahurin Honors College Capstone Experience/Thesis Projects
As anthropogenic influences take an ever-increasing toll on the environment, understanding how environmental change affects species is paramount. Concern regarding decline in amphibian populations has spurred research examining the effects of habitat change on the dynamics of populations at landscape levels. One important goal is to understand how gene flow among populations is affected by changes in habitat. Biologists need to consider the relationship between gene flow and habitat alterations so that movements among individual breeding ponds can be maintained over time, reducing risk of local extinction events. This study focuses on patterns of gene flow among thirteen populations of …
Detection Of Tetracyclines In An Anaerobic Waste Digester Using Solid Phase Extraction And High-Performance Liquid Chromatography Mass Spectrometry, Courtney Cruse
Mahurin Honors College Capstone Experience/Thesis Projects
Antibiotics are introduced to livestock to encourage growth and for the treatment of diseases. These antibiotics are not completely metabolized by swine, and thus these antibiotics are excreted with their waste. This poses a potential risk to human health as these antibiotics, a potential link to antibiotic resistant bacteria, then enter the surface water, ground water, and soil. In collaboration with the US Department of Agriculture (USDA) in Bowling Green, Kentucky, this research is concerned with analyzing the degradation of tetracyclines in swine waste from an anaerobic digester. Waste samples obtained from a digester and swine waste at the USDA …
Growth And Survival Of Salamanders Exposed To Different Formulations Of Glyphosate-Based Herbicide, Jessica Johnson
Growth And Survival Of Salamanders Exposed To Different Formulations Of Glyphosate-Based Herbicide, Jessica Johnson
Mahurin Honors College Capstone Experience/Thesis Projects
Amphibian populations have been experiencing rapid declines worldwide in the past few decades. There are many proposed causations, including the use of agricultural chemicals such as herbicides. Glyphosate based herbicides are one of the most widely used herbicides. This study looks at the effects of different brands of glyphosate-based herbicides, including those intended for aquatic use, on the survival and growth of axolotl salamander larvae. Out of four brands of glyphosate herbicide (Aquamaster, Aquaneat, Helosate plus, and Roundup Pro), the survival rates of Roundup Pro were the lowest. Most mortality occurred between the 3 mg/L and 6 mg/L concentrations, during …
