a Ordination (PCA) of mussel survival in percentages of batches of different species and size ranges during three sets of experiments with different experimental salinities and varying environmental conditions. b Ordination (PCA) of mussel longevity in days of individual mussel specimens during three sets of experiments with different experimental salinities and varying environmental variables. Size group 9 consisted of specimens with a shell length between 36 and 49 mm which is solely Mytilus edulis. All other size groups and the year of the start of the experiments were excluded from the graph as their correlations with species were only minor
