The paragraph below discusses the scientific questions behind my research:
Global climate change has implications for the persistence and distributions of
species. Because range shifts are likely the most important mechanism for
species persistence under rapid anthropogenic climate warming, understanding
limitations to current species&Mac226; range boundaries and predicting the potential
for range shifts is crucial for determining species&Mac226; responses and the role of
biodiversity management. My research addresses limitations to species
distributions for three species in the Lomatium genus that differ in abundance
from rare to common. Field experiments designed to understand limitations to
seedling establishment in current populations and beyond species range
boundaries are used to predict how each Lomatium species will likely respond to
climate change. Additionally, I am conducting a genetic survey to determine
levels of population genetic diversity and isolation. Results from field and
genetic data will be used to model the probability for species migration under
climate change for each of the three study species, focusing on the importance
of abundance for the likelihood of range shifts.
Further note: " I was also successful that day in finding L. utriculatum and
L. nudicuale on Goose Spit in Comox and L. nudicaule farther north along the
beach in Oyster River."
**Range: Scattered in Europe and North America, south to CA, NM and PA. BC range: Southern Vancouver Island (Sooke Hills, Mt. Benson, Port Alberni), Nairn Creek, Crevice Mtn.
Habitat: Vernal Pools, seepage areas
Rare status: R2 BC CDC status: BLUE Status outside: Rare in AB, NS, IL, IA, OR, WY, endangered in IN, WI, threatened in RI. Botrychium simplex also occurs on Texada Island, near Castlegar, and in Rogers Pass (Mount Revelstoke National Park and Glacier National Park). In Rogers Pass, it grows with the rare Hypericum scouleri ssp.nortoniae. There are a number of interesting plants that share a disjunct coastal bluff--inland bluff distribution; the hornwort Anthoceros punctatus and parasitic Orobanche uniflora are among them.-- Patrick Williston
