    Contributor(s): Matthew Joseph Cielinski

    Osteopetrosis is a metabolic bone disease in mammals characterized by a generalized skeletal sclerosis caused by reduced bone resorption. This reduced bone resorption is manifested in afflicted animals by abnormal bone shape, reduced or absent marrow cavities, extramedullary hemopoiesis, abnormal...

  5. Home range, habitat use, and food habits of the black bear in southcentral Florida

    Contributor(s): Wade Allen Ulrey

    I studied a small, enigmatic, and imperiled black bear population in south-central Florida from 2004 - 2006. Annual home ranges of males (96.0 km2) were larger than those of females (32.2 km2). Female home ranges were smaller in winter than in summer or fall. At the landscape scale, bears...

  6. Reduction in mucosal barrier markers with soy protein diet but not Lactobacillus rhamnosus GG in DSS-treated mice

    Contributor(s): Huanyi Jiang, Ruth S. MacDonald (adviser)

    Inflammatory bowel disease (IBD) is a common ailment affecting people of all ages. Even though the pathogenesis of IBD has not been fully elucidated, there is evidence that it involves interactions between genetic susceptibility, aberrant activation of the immune system, and the environment....

  7. Endocrine correlates of social and reproductive behaviours in a group-living Australian Passerine, the White-Browed Babbler

    Contributor(s): Suzanne Oppenheimer

    To investigate the evolutionary rationale for the seemingly altruistic behaviours commonly seen in cooperatively breeding Australian passerines, I examined alloparental behaviour in the White-browed Babbler Pomatostomus superciliosus (WBBA). Toward this end, I analysed behavioural, hormonal, and...

  8. Development of frequency modulated vocalizations in big brown bat pups

    Contributor(s): Heather W. Mayberry, Dr. Paul A. Faure (adviser)

    Developing bat pups produce distinct vocalizations called isolation calls (I‐calls) that serve to attract the bat's mother. Mothers use spatial memory, auditory and olfactory cues to reunite with their offspring. Because I‐calls are unique to individual pups, vocalizations are crucial for the...

  9. Behavioral ecology of savanna chimpanzees (Pan troglodytes verus) with respect to insectivory at Fongoli, Senegal

    Contributor(s): Stephanie Lynn Bogart, Jill D. Pruetz (adviser)

    In this dissertation I examine the behavioral ecology of savanna chimpanzees in Senegal. I test hypotheses related to the effects of the environment on the diet of the chimpanzees at Fongoli, concentrating on their insectivory specifically. Fongoli is the hottest and driest site in which...

  10. Developing an online horseless horse learning lesson: an action research study

    In today’s society it is becoming ever so important to find creative and influential outlets to keep young people occupied in positive ways. High quality youth programs are shown to make a positive difference in the lives of many young people; therefore, it is important to continue the use of...

  11. Improving beef cattle performance on tall fescue

    Contributor(s): Brian Thomas Campbell

    The overall goal of the studies described in this dissertation was to improve beef production of cows grazing endophyte infected tall fescue either through management practices or through identifying markers for genetic selection. Experiment 1 investigated differences in spring and fall calving...

  12. A candidate gene association study of cryptorchidism and scrotal hernia using canine and porcine models

    Contributor(s): Xia Zhao, Max Rothschild (adviser)

    Cryptorchidism and scrotal hernia, both being sex-limited complex defects, are the most common congenital defects observed in humans, dogs and pigs. It is believed that these two defects are controlled by multiple genes as well as affected by environmental factors. In this thesis, 22 or 14...

  13. From pasture to plate: A study of the rituals, ecology and economics of sheep in the context of Aid Al Adha in Morocco

    Contributor(s): Carrisa Sue Pritchard, Mokhtar Harras (adviser)
