Mortality In Interspecific Hybrids Of Nasonia Vitripennis And Nasonia Giraulti, Bonnie Cobb
Mortality In Interspecific Hybrids Of Nasonia Vitripennis And Nasonia Giraulti, Bonnie Cobb
Electronic Theses and Dissertations
Nasonia is a parasitoid wasp genus that serves as an emerging model for studying speciation due to an incompatibility between nuclear and mitochondrial genomes between sister taxa. Short generation times, easy rearing in a lab setting, producing large amounts of progeny, and whole genome sequencing make Nasonia is an excellent candidate for studying incomplete reproductive isolation. Nasonia have five chromosomes and exhibit haplo-diploid sex determination in which fertilized eggs develop into diploid females and unfertilized eggs develop into haploid males. Recessive phenotypes are hidden in diploid females but are laid bare in haploid males as there is no interaction between …
Stop, Then Go! Rapid Acceleration Offsets The Costs Of Intermittent Locomotion When Turning In Florida Scrub Lizards, Cheyenne Walker
Stop, Then Go! Rapid Acceleration Offsets The Costs Of Intermittent Locomotion When Turning In Florida Scrub Lizards, Cheyenne Walker
Electronic Theses and Dissertations
Intermittent locomotion is a commonly used escape strategy with a wide array of potential benefits. Pausing may aid in locating a predator, crypsis, lowering energy costs, and avoiding obstacles. Turning may also benefit from intermittent locomotion by allowing an animal time to assess its surroundings; therefore, decreasing the chances of making a mistake and/or stumbling. Florida scrub lizards live in environments with a variety of obstacles such as turns. The goal of this study is to quantify the locomotor behavior and performance by lizards while navigating a 45° or 90° turn. Lizards were run along both a 45° and 90° …
The Influence Of Faculty Peer Network Communication In The Diffusion Of A Centralized Cure, Nicole L. Scheuermann
The Influence Of Faculty Peer Network Communication In The Diffusion Of A Centralized Cure, Nicole L. Scheuermann
Electronic Theses and Dissertations
Course-based undergraduate research experiences (CUREs) provide students the benefits of undergraduate research participation by incorporating authentic scientific research into laboratory courses. CUREs are a relatively young pedagogy and are therefore innovative. Roger’s (2003) diffusion of innovations (DOI) framework posits that the diffusion of innovations, such as CUREs, is a highly social process. Most existing CURE research has focused on the impacts to students and the critical elements of CURE design. Investigation into instructor peer network communication is largely absent from the existing CURE literature. This study investigates the structure and function of a CURE community – the Malate Dehydrogenase CURE …
Hemocyte-Mediated Immune Response To A Bacterial Infection In The Cat Flea (Ctenocephalides Felis), Melanie Muñoz
Hemocyte-Mediated Immune Response To A Bacterial Infection In The Cat Flea (Ctenocephalides Felis), Melanie Muñoz
Electronic Theses and Dissertations
Despite their continued medical and veterinary importance, the vectorial capacity of fleas (Order Siphonaptera) is often underestimated. Fleas are best described as ectoparasites of a variety of mammalian and aviary hosts. In humans, fleas are infamous for the transmission of several detrimental agents, including those that cause plague, murine typhus, and cat-scratch disease. Although their significance in flea immune responses remains unknown, phagocytic immune cells, known as hemocytes, are important players in the cell mediated immune response of insects. Among invertebrates, hemocytes provide defense against foreign microbes via phagocytosis, cellular encapsulation, and the production of humoral immune factors. As mentioned …
