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

<p>A. Log(Abundance) = average of 100 log[<i>n</i>+1] values where <i>n</i> = 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.
