Fig. 4: Effect sizes resulting from the spatial autoregressive model with error term testing the six predictor variables of mean speciation rate variability among bioregions (n = 32).
From: The latitudinal variation in amphibian speciation rates revisited
Values to the right of the zero line depict positive relationships between the response variable and the respective predictor (i.e., speciation rate increases as the predictor increases), and those to the left show negative relationships. Grey circles represent variables with non-significant effects and blue circles represent effects with statistical significance (p < 0.05). Error bars represent the corresponding 95% confidence intervals.
