| Abstract | Abstract: To determine the invasion threat to the NE Pacific of marine algae arriving on Japanese debris from the 2011 Great Tōhoku Earthquake and Tsunami, my colleagues and I identified the algal species on 42 of the most heavily fouled debris items that landed on the shores of Oregon and Washington between June 2012 and July 2016. Using both morphological and molecular methods, we identified 80+ marine algal and cyanobacterial species and species complexes on debris verified to be from the Japanese tsunami. Since many of these species are not well-described in the literature, a morphological account of the actual specimens has been prepared to assist in the detection of future invasions by these species in the NE Pacific. The series is divided into 3 parts: Part 1 – The tsunami event, the project overview, and the red algae, Part 2 – The brown algae, and Part 3 – The green algae and cyanobacteria. In Part 2 that follows, we provide pictures and descriptions of 30 brown algal species and 3 unknowns that we have found on debris. We also include descriptions of many of the morphological and/or genetic variants that we discovered in the following 7 species:Ectocarpus arctus, Feldmannia irregularis, Feldmannia mitchelliae, Kucuckia spinosa, Petalonia fascia, Punctaria latifolia, and Scytosiphon lomentaria. Some of these variants indicate that species synonymies should be made and others imply that new species should be described. For additional information on all of the debris algal species, please see our related papers on the project (cited on p. 2 of the text). |
