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?
