Map of sampling locations
Sample site markers are scaled to represent the mean number of protosteloid amoebae fruiting bodies encountered for each line of substrate observed from that site. N = species richness observed at each major latitudinal range.
Collection site locations and characteristics
Supplementary table 1 - Collection site locations and characteristics. Number of lines plated refers to the number of lines of substrate observed from each site.
Summary of species observations
Table 1 - Summary of species observations. A=abundant, C=common, O=occasional, R=rare *p<0.05; **p<0.01; ***p<0.001 (All tests: significant difference between Aerial and Ground litter abundance; one-way ANOVA test)
Species encounters along environmental variables
Regressions of all observations of fruiting bodies' richness and abundance against latitude, elevation, and annual rainfall.
