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?
