Table 1 -

Results of a) a PERMANOVA analysis testing the effects of zones, capes, sites, years, and their interactions on intertidal community dissimilarity in Oregon and Northern California from 2006–2021. Cape, site, and year were treated as random factors. b) Results of SIMPER analysis testing the contributions of taxa to within-zone similarity. Only the top ten taxa contributing most strongly to within-zone similarity are listed. Communities were analyzed at the transect level (the average of ~10 0.5 x 0.5m quadrats).
