Effect of incorporating historical records in the spatial prediction of (a) species richness and (b) habitat suitability for the five species most impacted by neglecting historical records. The first column is the prediction of species richness/habitat suitability obtained from the RECENT dataset (post-1950 records) and the second column is obtained from the TOTAL dataset (historical + recent records). The last column is the difference between column 2 and column 1. We highlight the five species most impacted through neglecting historical records according to their PC1 score: lion Panthera leo, African wild dog Lycaon pictus, African elephant Loxodonta africana, spotted hyaena Crocuta crocuta and hippopotamus Hippopotamus amphibius.
