Summary of multiple logistic regression models based on dataset with single-region and single-interval genera removed. Each column represents an interval and each row a predictor. Colours indicate sign of log-odds associated with the predictor in a given interval and text gives the log-odds. Positive log-odds (magenta) indicate that as the predictor value increases marginal extinction risk increases; negative log-odds (green) indicate that as the predictor value increases marginal extinction risk decreases. Only predictors that are significant at the 95% confidence level are plotted. S2: Sandbian 2, K1: Katian 1, K2: Katian 2, K3: Katian 3 ,K4: Katian 4, H: Hirnantian. Because Sandbian 1 is the first interval in our database all genera that last appear in this interval are by definition of single-interval genera; hence Sandbian 1 is not included in selectivity analyses of the culled dataset.
