marginally insignificantp = 0.97
All other species were non-significant, however there was a marginally insignificant effect of CO 2 exposure on P. cylindrica (sequential permutation test for RDA, site: F (2, 43) = 1.0, p = 0.97; CO 2 exposure nested within site: F (3, 43) = 3.9, p = 0.06). which was not considered to be ecologically relevant (sampling was unbalanced as only one sample was found at Dobu High CO 2 , and only three of 49 samples yielded different types in the collection).
