  • The culture and biochemical analysis of some estuarine phytoplankton species

    Creator:
    DeMort, Carole Lyle
    Abstract:
    The biochemical composition of ten species of estuarine phytoplankton was determined. Studies were made of their growth in various culture media and of their relative value as food for oyster larvae. Nine of the species were isolated from Yaquina Bay, Oregon. An attempt was made to select species which commonly...

  • Genomic Investigations of Diversity within the Milkweed Genus Asclepias, at Multiple Scales

    Creator:
    Weitemier, Kevin A.
    Abstract:
    At a time when the biodiversity on Earth is being rapidly lost, new technologies and methods in genomic analysis are fortunately allowing scientists to catalog and explore the diversity that remains more efficiently and precisely. The studies in this dissertation investigate genomic diversity within the milkweed genus, Asclepias, at multiple...
