Relationship between long-term predictions of sessile species composition derived from Markov chain models, parameterized from transitions in each year in relation to average annual pH. Taxon codes as in Fig. 2, with calcareous taxa indicated by bold italics. (A) Predicted taxa composition of each year, sorted by average pH in that year. (B) Taxon loadings of the first principle component, which describe annual variation in long-term predictions of taxon composition by Markov chain models. Open triangles are calcareous taxa. (C) Relationship between the first principle component that described long-term predictions of taxon composition by Markov chain models and the average annual pH.
