Abundância de invertebrados de solo encontrados em diferentes ambientes na Universidade Federal da Fronteira Sul/Campus Chapecó-SC

Abstract

Brazil is one of the major mega-diverse countries in the world, housing about 15% to 20% of all existing species. However, the current knowledge of this biota is extremely heterogeneous. Among all existing classes, arthropods of the class insecta are considered the largest group. The objective of this study was to quantify the composition of fauna, which inhabiting the soil at the Federal University of Fronteira Sul (UFFS) area, this was done with different environments. The study was conducted at the Federal University of Fronteira Sul. There was a selection of five different environments to carry out the collection: An area with a predominance of pine, eucalyptus, tillage, initial succession and native forest. The insects were collected over a period of 26 hours, was used Pitfall traps in alcohol solution 70% and detergent, without the use of attractive. Traps were installed on 25 May 2015. After collection, the insects captured were screened under a stereomicroscope according to the order and stored in glass containers. It can be concluded that the areas around the Federal University of Fronteira Sul presented mainly of invertebrates belonging to the Araneae, Blattodea, Coleoptera, Collembola, Dermaptera, Diptera, Hemiptera, Hymenoptera, Odonata, Orthoptera and Thysanura. The areas with highest abundance and richness of invertebrates are the most diversity of plant species; areas with monocultures have less diversity and richness of invertebrates; the most abundant order in five areas sampled was the Hymenoptera, it presented significant numbers when compared to other invertebrate groups.
