Figure 1. The distribution of approximate census population sizes estimated by this study.

Some phyla containing few species were excluded for clarity.

Figure 1—figure supplement 1. The relationship between body mass and population density found by Damuth, 1987, which is used to predict population densities.

The source of this data is appendix table of Damuth, 1987; the color indicates Damuth’s original group labels. The dashed line was estimated using a lognormal regression model in Stan. References to each measurement are available in Damuth, 1987.

Figure 1—figure supplement 2. The fraction of total species per class on earth included in this study’s sample, per class.

The color of the points represents phylum, and the size of the point represents the absolute number of species by class.

Figure 1—figure supplement 3. Comparison of this paper’s range estimates procedure against the IUCN Red List’s range estimates.

The correspondence between the ranges estimated with the alpha hull method applied to GBIF data used in this paper and IUCN Red List’s Extent of Occurrence for the subset of species in both datasets. Note that the IUCN Red List contains predominantly endangered species, which leads to ascertainment bias; still, the high correlation between the estimated ranges shows the alpha hull method works well.

Figure 1—figure supplement 4. Validation of this paper’s range estimates against the categorical labels of Leffler et al., 2012.

The estimated ranges using GBIF occurrence data, ordered within and colored by the original range category labels assigned in Leffler et al., 2012.

Figure 1—figure supplement 5. The relationship between body length (meters) and body mass (grams) in the Romiguier et al., 2014 data set.

The relationship between body length (meters) and body mass (grams) in the Romiguier et al., 2014 data set. This is used to infer body masses for taxa. The gray dashed line is the line of best fit inferred using Stan.
