Rodent Dental Microwear Texture Analysis As A Proxy For Fine-Scale Paleoenvironment Reconstruction, Jenny H. E. Burgman
Rodent Dental Microwear Texture Analysis As A Proxy For Fine-Scale Paleoenvironment Reconstruction, Jenny H. E. Burgman
Graduate Theses and Dissertations
Dental microwear texture analysis (DMTA) of fossil fauna has become a valuable tool for dietary inference and paleoenvironment reconstruction. Most of this work has utilized larger taxa with larger home ranges. These studies may result in broader-scale habitat inferences that could mask the details of complex mosaic habitats. Rodent DMTA offers an opportunity to work at finer spatial scales because most species have smaller home ranges. Rodents are also keystone species within their ecosystems, abundant, ubiquitous, and found in many fossil deposits. These attributes make them excellent proxies for environmental reconstructions. However, the application of DMTA to rodents remains relatively …
Macronutrient Availability Shapes Host Response To Infection And Feeding Behavior, Weston Gerald Perrine
Macronutrient Availability Shapes Host Response To Infection And Feeding Behavior, Weston Gerald Perrine
Graduate Theses and Dissertations
Macronutrients in the diet are vital to the physiological processes necessary for an organism to effectively clear a pathogen. Diet can be important to a host’s susceptibility to infection and severity of pathology, though results can vary across host-pathogen systems (Sen et al. 2016). Manipulating the ratio of specific macronutrients in the diet is an effective method to begin understanding how individual macronutrients, rather than food types, have on immune responses. Using an avian host-pathogen system, I explored the effects of dietary macronutrient composition, specifically lipid and protein content, on disease pathology and behavior of canaries (Serinus canaria) infected with …
