Model selection testing correlations between relative richness and sea surface temperature (SST) and chlorophyll a (CHL). (The full model included a soap film smooth term (XY) and measure of habitat availability (null). Models shown are those within 6 ΔAIC of the best-supported model. Adj R2 of best-supported model = 0.60.)
