“Marine Algae on Japanese Tsunami Debris and the Risk of Invasion”.
Gayle I. Hansen, Department of Botany and Plant Pathology, Oregon State University talks to the MidCoast Watersheds Council
Approximately 50 species of marine algae were identified on Japanese debris arriving on Oregon and Washington shores from the Great Tohoku Earthquake and Tsunami. Of these, 76% were found to be fertile and dropping spores. By examining the prevalence of the species on debris, their life forms, successional types, and world distributions, it was possible to evaluate the risk of recruitment and possible invasion. The diagnostic features of many of the algal species will be illustrated in the talk.
Presentation by Dr. Gayle Hansen, OSU, HMSC Campus-EPA. The MidCoast Watersheds Council meets this Thursday, 6:30pm at the Central Lincoln Peoples Utility District “Public Room,” located across 101 from Safeway. The public is invited to attend and learn about scientific discoveries and developments in this emerging situation along our Oregon Coast.
