Diversity of Papilionoidea-Lepidoptera and representativeness of data from non-linear models in the Oglán Alto Forest, Neotropical Forest, lower Curaray River Basin, Pastaza …

Abstract:

Neotropical forests harbor the greatest biodiversity on the planet. Measuring this biodiversity is a challenge that often presents drawbacks when modeling this diversity. These drawbacks have two main causes: 1. the sampling designs and 2. the numerical models used. The objective of this work was to determine the degree of representativeness of the data obtained in a sampling of a community of Papilionoidea-Lepidoptera in an Amazonian Forest of Ecuador, under two non-linear models. To collect data, Van Someren Rydon traps were placed considering two vertical strata (canopy, understory) and three altitudinal ranges, collecting continuous data for 11 months. The data were analyzed with the non-linear models Clench's Equation and negative exponential and were contrasted with Simpson's Inverse and Shannon's Exponential diversity indices. It was determined that the design performed and taxon (Papilionoidea) fit adequately with the negative exponential equation, fit R2= 0.99; slope< 0.1. The non-linear models allowed for determining the ideal model for the fit of the data with the sampling, the amount of fauna inventoried, and the sampling effort required to conclude the inventory, therefore, the negative exponential equation is a more adequate alternative to measure the diversity of less extensive areas and known taxa, than the traditional indexes.
