Figure 3. Community model predictions under different scenarios of stress effects.

Boxplots of the negative log-likelihood of the change in community productivity (a) and average negative Bray–Curtis dissimilarity index (b) for five scenarios of stress-induced effects in the per capita strength of species interactions. Scenario 1 is the baseline scenario without interspecific interaction (A_ij=0). Scenario 2 corresponds to equal inter- and intraspecific interaction strength (A_ii=A_ij). Scenario 3 corresponds to a constant ratio of inter- to intraspecific competition (A_ii,0/A_ij0=A_ii250/A_ij250). Scenario 4 corresponds to a constant per capita strength of interspecific interactions (A_ij0=A_ij250). Scenario 5 did not impose any limitations to changes in per capita interaction strength. Higher values indicate a better model fit and scenarios that do not share a common letter are significantly different (Bonferroni-corrected Wilcoxon signed-rank test: P<0.05). Boxplot whiskers correspond to maximal 1.5 times the interquartile range.
