TABLE 2 in Distribution of epigaeic ants (Hymenoptera: Formicidae) across the transition between the Subantarctic and Patagonian subregions of the Andean region

TABLE 2. Sample completeness and evenness. The numerical values for the three special cases of q = 0, 1 and 2 for incidence data of ant species in forest, shrubland and steppe for the four steps of the framework of Hill numbers (Chao et al., 2020) implemented in the R package iNEXT.4steps (Chao & Kubota, 2024) are shown. SR = species richness, obs = observed, asy = asymmetric, Cmax = maximum standardized coverage (i.e., minimum coverage of samples extrapolated to double the size of the reference sample).
