  • Reproductive biology and behavior of the brown tree snake (Boiga irregularis) on Guam.

    Creator:
    Waye, Heather L.
    Abstract:
    While there are many more species of reptiles in the tropics than in temperate latitudes, relatively little is known about the natural history of tropical species of snakes. Even basic information, such as reproductive ecology and behavior, is lacking. Patterns of reproduction in tropical species differ from patterns in temperate...

  • Reproductive Effects of PG-600 Administration in Ewes

    Creator:
    Habeeb, Hayder
    Abstract:
    Sheep are seasonally polyestrus, which means they do exhibit estrus and ovulation during the short daylight (breeding season) and do not during the long daylight (nonbreeding season). To stimulate the ewes to ovulate during the nonbreeding season, various hormonal treatments have been used. PG-600 contains both equine chorionic gonadotropin and...

  • Nearshore distribution of barnacle and mussel larvae and oceanographic mechanisms of onshore transport and delivery

    Creator:
    Tyburczy, Joe A.
    Abstract:
    Recruitment of larvae from the plankton is an important determinant of community structure in marine systems. In populations of many marine species, recruitment determines the basic demographic parameters of immigration, emigration, and reproduction. Moreover, the effect of recruitment as an "ecological subsidy" can determine the strength of interactions among species...

  • Wide band gap semiconductors and insulators : synthesis, processing and characterization

    Creator:
    Hersh, Peter A.
    Abstract:
    The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

  • Dynamics of the Laurentide Ice Sheet

    Creator:
    Carlson, Anders Eskil
    Abstract:
    This dissertation concentrates on the controlling factors on the instability of the Laurentide Ice Sheet (LIS) and their effects on abrupt climate change. Northern Hemisphere climate fluctuated abruptly during the last deglaciation possibly related to variability in Atlantic meridional overturning circulation (AMOC) and reduced aerial extent of the LIS. Reductions...

  • Greater sage-grouse reproductive ecology : linkages among habitat resources, maternal nutrition, and chick survival

    Creator:
    Gregg, Michael A.
    Abstract:
    Greater sage-grouse (Centrocercus urophasianus) populations declined range wide during the past 50 years. Grouse populations were 2-3 times larger than the current population as recently as the early 1970's. In addition to habitat loss and fragmentation, declines were attributed habitat degradation that caused reduced productivity. Because chick survival remains the...

  • Towards Narrative Understanding with Deep Neural Networks and Hidden Markov Models

    Creator:
    Orr, J. Walker
    Abstract:
    Narratives are central to communication and the human experience. For a computer system to understand a narrative, it must be able to identify the key facts or plot elements that describe what happened or how the world has changed. These element are called events;establishing a document’s events and the relationships...

  • Examining Evidence-based Intervention Sustainability and De-adoption in the Context of HIV Prevention

    Creator:
    McKay, Virginia R.
    Abstract:
    Evidence-based interventions (EBIs), which demonstrate efficacy in research settings, are rarely sustained when implemented in public health organizations. Rather, EBIs are often de-adopted - potentially undermining the positive benefits of the EBIs for the communities that access them. The lack of sustainability is particularly troubling among public health organizations that...

  • The Effects of Host and Pathogen Variation on Infection Dynamics in the Amphibian-Chytrid System

    Creator:
    Dang, Trang D.
    Abstract:
    This dissertation uses manipulative experiments to explore amphibian-Bd infection dynamics. Although there has been almost two decades research since the discovery of Bd, many questions still remain regarding what conditions mediate chytridiomycosis virulence. My research shows how certain host and pathogen factors can influence disease virulence. Identifying how host and...

  • On the evolution of correlated color traits in garter snakes

    Creator:
    Westphal, Michael F.
    Abstract:
    How complex traits evolve continues to be a major focus of evolutionary investigation. A current topic of debate is the hypothesis that the phenotypic integration of complex traits gives rise to evolutionary constraints. I studied two color traits in the common garter snake, Thamnophis sirtalis, that show a high level...
