| Abstract | Two sampling lines were established in the intertidal region at each of three geographically separate sites on the coast of Oregon. Each sampling line, which was positioned in the zone dominated by the brown alga Hedophyllum sessile, was one meter in height and extended 50 meters horizontally. Information was sought concerning primarily the possible biological dependence of one species on another or the biological exclusion of one species by another. Secondary information was gathered on the floristic differences at intra- and inter-site levels. No examples of exclusion were established but two putative cases of dependence were detected. Considering the factors of observed occurrences and co-occurrences, as well as calculated coefficient of association values, biological dependency was suggested for the algal pairs Ulva expansa - Ralfsia pacifica and Gigartina papillata - Endocladia muricata. The sampling lines at only one of the three sites differed greatly in the probability of chance distribution of species. However, large differences were noted among each of the sites. All sites were surveyed and the exact location of sampling lines are noted on aerial photographs. |
