Rarefaction and extrapolation richness curves for carabid beetles from Armero (A–C), and Armero and Cambao combined (D–F) A, D comparison of richness between habitats using sample-size-based curves B, E sample completeness curves C, F comparison of richness using coverage-based curves. Abbreviations: F = forest, ES = early succession, P = pasture. Numbers in parentheses denote sample sizes and the observed Hill number (q = 0) (A, D), sample size and the estimated sample coverage (B, E), and the estimated sample coverage and the observed Hill number (q = 0) (C, F), respectively.
