Species recorded in the Lagamar do Cauipe lagoon and their life-forms accordingto Sculthorpe (1967). (A) Hydrophytes attached to the substrate: (A1) emergenthydrophytes; (A2) floating-leaved hydrophytes; (A3) submerged hydrophytes; (B)free-floating hydrophytes; and (C) helophytes. Lagamar do Cauipe, Caucaia municipality,Cea state, Brazil. EAC Number: selected collection for the species in the EACherbarium. Herbarium record: species not sampled by the phytosociological plots,but recorded in the EAC herbarium for the Lagamar do Cauipe.
Using the second mathematical approach presented by Colwellet al. (2012, Eq. (20)), we estimated the number of plots neededto sample a given proportion of the asymptotic richness. Followingthis method we estimated that to sample 80% of the total richnessestimated by Chao 2 we would need 100 plots. To sample 90% ofthe asymptotic richness, 195 plots would be needed; 293 plots tosample 95%, and astonishing 580 plots to sample 99% of the totalrichness.
