  • Seasonal thermoregulation in the dark-eyed junco (Passeriformes: Junco hyemalis)

    Creator:
    Swanson, David Leslie
    Abstract:
    Winters in north-temperate climates impose high thermogenic demands upon small birds which are met by seasonal acclimatization. This thesis investigates the extent and mechanisms of seasonal acclimatization in darkeyed juncos (Junco hyemalis) inhabiting western Oregon. Although insulation is significantly increased in winter, acclimatization is primarily metabolic. Increased metabolism is required...

  • Ecological responses to riverine floods and flow alteration

    Creator:
    McMullen, Laura E.
    Abstract:
    Floods are major disturbance events for riverine ecosystems, directly and indirectly impacting organisms and their habitat. In this study I investigated the role of riverine floods and flow alteration in regulating aquatic macroinvertebrate population and community structure. I examined this problem using a variety of methods: a meta-analytic review of...

  • 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...
