  • Hypothalamic Leptin Gene Therapy Does Not Prevent Ovariectomy-Induced Bone Loss in Rats

    Creator:
    Jackson, Melanie A.
    Abstract:
    Post-menopausal women are at an increased risk for osteoporosis due to increased bone resorption associated with estrogen deficiency. Subcutaneous administration of leptin, a hormone produced primarily by adipocytes, attenuates bone loss in the ovariectomized (ovx) rat, an animal model for post-menopausal bone loss. Leptin has both direct peripheral and indirect...

  • A genomic and proteomic characterization of the first cultured oligotrophic marine Gammaproteobacterium from the SAR92 clade

    Creator:
    Mellbye, Brett L.
    Abstract:
    High-throughput culturing (HTC) consisting of extinction culturing in autoclaved seawater has led to the isolation and characterization of many novel strains of oligotrophic marine bacteria. Strain HTCC 2207 was isolated from the Oregon coast by the HTC method. Phylogenetic analysis based on 16S rRNA gene sequence showed that this strain...

  • Evaluating larval size and survival after probiotic addition in Pacific oyster larvae

    Creator:
    Grant, Ian
    Abstract:
    Oysters are a large part of the American aquaculture market, and the oyster farming industry was valued at over 1 billion dollars in 2021. However, oyster farmers often face issues surrounding the mortality rates of their stock. One cause of this is infections caused by Vibrio coralliilyticus (Vcor), a bacterium...

  • The effects of marine biodiversity loss on coastal economics

    Creator:
    McAbery, Emma
    Abstract:
    The oceans are one of humanity’s greatest resources, providing food, raw materials, livelihoods, and protection. More than 3 billion people around the world rely on marine life as a source of protein as well as their livelihood. Seafood is one of the highest traded commodities globally and many major cities...

  • Arsenic methylation by marine cyanobacteria Prochlorococcus and Synechococcus

    Creator:
    Lee, Mikaela
    Abstract:
    Our experiments aimed to investigate responses of the marine cyanobacteria Prochlorococcus and Synechococcus to toxic arsenic species, such as arsenate, and to understand cellular mechanisms that contribute to arsenic tolerance. We used two strains of Prochlorococcus, a high-light adapted MED4 and low-light adapted MIT9313, both axenic, for cultivation experiments. For...

  • Impact of biased movement on marine protected area effectiveness

    Creator:
    Rekow, James Alexander
    Abstract:
    Fish mobility affects the distribution of commercially caught fish species in marine protected areas (MPAs) and unprotected areas, which we will call fishing grounds (FGs). Previous theoretical findings predicted that highly mobile fish would benefit little if at all from protection in MPAs (Demartini 1993, Walters et al. 1999). However,...

  • Marine Nitrogen Subsidies to Terrestrial Systems: Transport Through Wrack Deposition

    Creator:
    Traylor, Andrew
    Abstract:
    Fluctuations in one system affect adjacent systems; mechanistic understanding of linkages helps conservation efforts be more effective by focusing on influential species and areas that facilitate connections between ecosystems. This study explored marine-derived nutrient inputs to adjacent terrestrial communities. We quantified wrack (seaweed and other organic matter) deposition at sites...

  • Biologically Active Secondary Metabolites from Red Sea Cyanobacteria

    Creator:
    Alhadab, Ali A.
    Abstract:
    This project describes the investigation of marine cyanobacteria collected from the Red Sea with an emphasis on the identification and prioritization of biologically active fractions for future purification and molecular structure elucidation of medicinally relevant secondary metabolites. Five crude extracts of taxonomically unidentified Red Sea cyanobacteria supplied by Egyptian collaborators...

  • Using The MPA Guide to Better Understand Global Marine Conservation Efforts

    Creator:
    McArthur, Madeleine G.
    Abstract:
    Across the globe, Marine Protected Areas (MPAs) have been established to protect biodiversity, sustain fisheries, and preserve cultural resources. However, there exist broad differences among MPAs with respect to their establishment stage and protective regulations, making it difficult to quantify how much ocean protection is actually occurring. This thesis utilizes...

    Destine, Karina
    Abstract:
    The structural and chemical diversity of natural compounds represents a vast amount of potential in terms of new drug discovery. This project examines the cytotoxic potential of the marine natural product mandelalide A and seeks to understand whether or not exposure to this compound induces programmed cell death in cancer...
