Inflorescences of the Bromeliad Vriesea friburgensis as Nest Sites and Food Resources for Ants and Other Arthropods in Brazil

Figure 2

Diversity of ants inhabiting infructescences or visiting inflorescences of Vriesea friburgensis, according to habitat type on Santa Catarina Island, southern Brazil. Plotted against number of species occurrences as measure of sampling effort are (a) species accumulation curves and their 95% confidence limits; (b) Chao2 species richness estimator including 95% confidence limits; (c) rarefaction curves of Simpson diversity index; and (d) Simpson evenness (Simpson diversity divided by the number of species observed). Diagrams with the same data but with logarithmically scaled 𝑥-axes are included in the Supplementary Material (Supplementary Figure S5).
