  1. A positive correlation between public interest and the number of occurrences was found in most classes. Values followed by * have a significant p-value at a 5% threshold. (+) indicates a positive influence while (-) indicates a negative influence of the variable on the number of occurrences. Nb species = number of species used in the GLM after removing outliers; pval = p-values; NA = not available (because no order information and therefore no research quantity was available for Pinopsida).
