  • Evolutionary relationships and an investigation of sympatric speciation within Limnanthaceae

    Creator:
    Meyers, Stephen C.
    Abstract:
    Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies of Limnanthes floccosa endemic to vernal pools in southern Oregon and northern California. Three seasons of monitoring natural populations have quantified that L. floccosa ssp. grandiflora is always found growing sympatrically with L. floccosa ssp. floccosa...

  • 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...

  • The influence of prescribed fire on the rare endemic plant Delphinium pavonaceum (Peacock larkspur)

    Creator:
    McKernan, Brie-Anne
    Abstract:
    In the wetland prairie of William L. Finley National Wildlife Refuge (FNWR) in western Oregon, we investigated the response of Delphinium pavonaceum Ewan (peacock larkspur, Ranunculaceae), an endangered perennial forb, to four unreplicated dormant season fire regimes of 0, 2, 4, or 10 fires that were applied over a 12-year...

  • Reproductive isolation and interspecific hybridization in the threatened species, Sidalcea nelsoniana

    Creator:
    Gisler, Steven D.
    Abstract:
    In addition to its longstanding recognition as an influential evolutionary process, interspecific hybridization is increasingly regarded as a potential threat to the genetic integrity and survival of rare plant species, manifested through gamete wasting, increased pest and disease pressures, outbreeding depression, competitive exclusion, and genetic assimilation. Alternatively, hybridization has also...
