Research
Phylogeography of vascular plants and terrestrial non-vascular cryptogams (bryophytes and lichens) with an emphasis on species narrowly restricted to alpine and hyperoceanic environments in Pacific Northwestern North America. Application of methods in molecular systematics to testing hypotheses about the origins of the alpine and hyperoceanic floras. Comparative study of genetic variation within and among populations of geographically widespread vs. geographically restricted species from those environments.Current Research ProjectsHistorical evolution and origins of rare lineages and the practice of conservation biology as it applies to naturally rare species. Application of knowledge about stenoclimatic floras from geographically restricted mesohabitats to the problem of monitoring the effects of climate change on the biota.
Taxonomic and floristic research for treatments of several genera and families included in the forthcoming Flora of North America, Vol. 29, Marchantiophyta. Future research plans include a series of research expeditions into the North Cascades and coastal archipelagos of British Columbia and southeastern Alaska, and eventually to the Aleutian Islands.
Phylogeographic analysis of molecular and morphological variation in Gaudichaudia (Malpighiaceae), a genus of vines with a mixed mating system forming a hybrid complex among tetraploid lineages. Methods include analysis of restriction sites on the chloroplast genome, randomly amplified DNA, and morphometric analysis. Recent taxonomic revisions include description of six new species.
