  • Drought, dispersal, and community dynamics in arid-land streams

    Creator:
    Bogan, Michael T.
    Abstract:
    Understanding the mechanisms that regulate local species diversity and community structure is a perennial goal of ecology. Local community structure can be viewed as the result of numerous local and regional processes; these processes act as filters that reduce the regional species pool down to the observed local community. In...

  • Diversity and community structure of aquatic insects in isolated montane desert streams

    Creator:
    Bogan, Michael T.
    Abstract:
    Local aquatic insect diversity and community structure is the result of multiple local and regional factors, and observed patterns depend upon the spatial and temporal scale under examination. Isolated stream systems in arid regions represent a new challenge in understanding the drivers of diversity and community structure, as most studies...

  • The role of costimulation and adjuvants in the development of T cell effector and memory responses

    Creator:
    Maxwell, Joseph R.
    Abstract:
    T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...

  • Broad-scale patterns of invertebrate richness and community composition in temporary rivers : effects of flow intermittence

    Creator:
    Datry, T., Larned, S. T., Fritz, K. M., Bogan, M. T., Wood, P. J., Meyer, E. I., and Santos, A. N.
    Abstract:
    Temporary rivers are increasingly common freshwater ecosystems, but there have been no global syntheses of their community patterns. In this study, we examined the responses of aquatic invertebrate communities to flow intermittence in 14 rivers from multiple biogeographic regions covering a wide range of flow intermittence and spatial arrangements of...

    Gordon, Michael Ian
    Abstract:
    Anaerobic digestion of lipid-extracted algal biomass has been proposed as a method to recover and recycle nutrients in algal biofuel systems. The purpose of this study was to quantify recoverable nitrogen and phosphorus from anaerobically digested C. vulgaris. Recoverable nutrients were deemed those present in the liquid phase of anaerobic...

  • Uncovering the mechanism of IL-4-mediated T cell survival

    Creator:
    Moscibrocki, Cathleen M.
    Abstract:
    Although IL-4 is a well-characterized multi-functional cytokine, its role as a survival factor in T cells is not completely understood. In an attempt to uncover IL-4-mediated survival, we studied caspase activation in primary mouse T lymphocytes undergoing death by neglect, activation-induced or steroid-induced cell death. Here, we identify the executioner...

  • The influence of aryl hydrocarbon receptor activation on T cell fate

    Creator:
    Funatake, Castle J.
    Abstract:
    2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related compounds are well-recognized for their immunosuppressive activity, which is mediated through an intracellular receptor and transcription factor, aryl hydrocarbon receptor (AhR). Laboratory animals exposed to TCDD are less resistant to infection and have severely impaired humoral and cell-mediated immune responses. This dissertation addressed the hypothesis that...

  • Acid-sensing ion channels in mouse olfactory bulb M/T neurons

    Creator:
    Li, Ming-Hua, Liu, Selina Qiuying, Inoue, Koichi, Lan, Jinquan, Simon, Roger P., and Xiong, Zhi-Gang
    Abstract:
    The olfactory bulb contains the first synaptic relay in the olfactory pathway, the sensory system in which odorants are detected enabling these chemical stimuli to be transformed into electrical signals and, ultimately, the perception of odor. Acid-sensing ion channels (ASICs), a family of proton-gated cation channels, are widely expressed in...

  • Expression of Follicle Stimulating Hormone (FSHβ) and its Receptor (FSHR) within the Ovine Placentome

    Creator:
    Wu, Eleas M.
    Abstract:
    Follicle stimulating hormone (FSH) plays a key role in the ewe’s estrous cycle but understanding its continued importance during pregnancy is not well understood. Researchers have proposed a model theorizing that a cascade of hormones is responsible for pregnancy maintenance. Weems et al. proposed a model for placental progesterone production;...

  • Activation, modification and suppression of sex pheromone production in garter snakes

    Creator:
    Parker, M. Rockwell
    Abstract:
    Vertebrates communicate with one another and coordinate intraspecific reproduction by using a variety of sexually dimorphic signals, such as plumage, ornaments, sounds, and/or scents. These sexual dimorphisms are maintained by physiological factors, typically sex-specific hormones (though see Chapter 3 for an exception). The purpose of the research in this dissertation...
