Paul W. Gabrielson
(b. 19 November 1952)
Since returning to the University of North Carolina
at Chapel Hill in August, 2000 after 10 years of more seaweed research
following my Ph.D. at the U.N.C., plus 10 years teaching at a small,
liberal arts college, I am back to where I started as a graduate student,
doing algal systematics, but now with a molecular twist.
Teaching the summer Marine Botany course intermittently over the past 15
years at the Friday Harbor Labs (FHL), University of Washington's marine
lab on San Juan Island in northern Puget Sound, has shaped my career,
resulting in publications used by students and professionals to identity
marine algae: in 2004 "Keys to the Seaweeds and Seagrasses of Oregon
and California, North of Point Conception", and in 2006, "Keys to
the Seaweeds and Seagrasses of Southeast Alaska, British Columbia,
Washington and Oregon", both with my colleagues Dr. Sandra Lindstrom
and Dr. Tom Widdowson. Familiarity with the Northeast Pacific seaweed
flora, primarily stimulated by writing the Keys as well as trying to answer
students' questions in the field, has stimulated further systematic
research.

Currently, I am obtaining molecular fingerprints
from recent field-collected specimens to compare with those obtained from
type specimens, many dating from the 19th Century. This ability to
unequivocally match type and historically important collections with recently
collected specimens allows us to explore a host of questions that hitherto
have been difficult to answer. For example: Are names of seaweeds with type
localities outside of the Northeast Pacific correctly applied to local
species? What are the biogeographic limits of morphologically similar
species? the ecological limits? Are invasive species present that are
morphologically similar to native species?
