Figure 2. Ant abundance and richness variables as a function of elevation among 41 Central American wet forest sites.

A. Log(Abundance) = average of 100 log[n+1] values where n = number of workers in 1 m². B. Percent of samples containing ants. C. Species Richness = number of species in 100 samples (taxon subset; see text). D. Abundance per species = Abundance as defined in panel A/Richness as defined in panel C. LOESS curves are included for A and C, using default parameters in R 3.0.2.
