Edaphic macrofuana estimate site set to present in forest trees, fruit and acahual

Abstract

The soil macrofauna has a major role in fertility and physical structure of the soil, as some of these agencies carry out activities whose impact is positive, for example, the regulation of plant available nutrients thereby modifies the environment surface soil and where they develop, for the above work was done macrofauna on two plots established with forest trees, one with fruit trees and a acahual. Sampling was conducted in the months of July and September, which was determined through the Shannon-Wiener index. Sample groups were divided into worms, spiders, ants, termites, beetles, isopods, chilopods, Diplopoda and others. The results showed that comparison of the macrofauna using the Shannon-Wiener index showed that the diversity of species assessed was low, presenting a rate of 0.71 for fruit and 0.78 site in the forest which represented 8 and 12 species respectively, and acahual like 12 in addition to being low in terms of the index is also low species present in terms of individual per species. To make these results it was estimated fairness, which showed that there is a distribution of species abundances perfectly equal. Therefore we could not determine the abundance index of species present at the sites evaluated as the density of individuals per square meter was low. Therefore it can be concluded that the richness of macrofauna on the sites evaluated in terms of numbers and species present is low.
