Data from: Geographic ranges of genera and their constituent species: structure, evolutionary dynamics, and extinction resistance

Michael Foote, Kathleen A. Ritterbush & Arnold I. Miller
We explore the relationships among the geographic ranges of genera, the ranges and positions of their constituent species, and the number of species they contain, considering variation among coeval genera and changes within genera over time. Measuring range size as the maximal distance, or extent, between occurrences within a taxon, we find that the range of the most widespread species is a good predictor of the range of the genus, and that the number of...
