  • New insights into the biology of theropod dinosaurs

    Creator:
    Quick, Devon E.
    Abstract:
    There is little, if any, direct fossil evidence of the cardiovascular, respiratory, reproductive or digestive biology of dinosaurs. However, a variety of data can be used to draw reasonable inferences about the physiology of the carnivorous theropod dinosaurs (Archosauria: Theropoda). Extant archosaurs, birds and crocodilians, possess regionally differentiated, vascularized and...

  • Determination of mode of death of John Day Merycoidodontidae (Oreodontidae) by populaton age structure analysis

    Creator:
    Brown, Melinda Elaine
    Abstract:
    Volcanic activity during the Tertiary has long been held responsible for the deaths and subsequent fossilization of the vertebrate populations of the John Day region in Oregon. Oreodonts as plains or savannah dwelling ruminant herbivores, were likely to have been subject to potential exposure throughout their lifetime to volcanic debris...

  • Neural regulation of immunity in teleosts

    Creator:
    Flory, Craig M.
    Abstract:
    It has long been observed that stress can increase our susceptibility to infectious diseases and cancers. Recent experimental evidence suggests that this increased susceptibility is due to suppression of immunity. A variety of neuroendocrine products are released during periods of stress, and a large number of these are now known...
