  • 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...

  • 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...
