Table 2 Results of spatial autoregressions of marine bivalve diversity on environmental variables. Diversity values shown are for the S2/m equation of Alroy (2020); other diversity metrics are detailed in the supplementary material (Table S1-2). Values are beta coefficients generated by each model (significance values *p< 0.05, **p< 0.01). R2 values are for the whole model. “Optimal submodel” details the best subset of environmental predictors for each dataset (see main text); the values in parentheses are the R2s for those submodels. MAT = Mean Annual Temperature.
