Odonate Fauna (Insect: Odonata) of Two Ponds in the Cerradopantanal Ecotone, Aquidauana, MS

Abstract

Knowing the biodiversity of a given site is the first step in establishing strategies for its conservation, monitoring and sustainable use. The objective of the present study was to catalogue the Odonata community of two ponds in the Cerrado-Pantanal ecotone area. Collections were carried out between October 2012 and September 2013, encompassing different hydrological seasons. This study presents the first systematized survey of Odonata for lentic environments in the region. A total of 347 individuals were recorded, distributed in 41 species, 22 genera and three families. The suborder Zygoptera was represented by the Coenagrionidae and Lestidae families, while the suborder Anisoptera was represented by the Libellulidae family. The Acanthagrion, Erythemis and Erythrodiplax genera were the most representative. The results indicate that there is seasonality in the occurrence of the species. The wide diversity found in lentic environments emphasizes the importance of long-term monitoring of these ecosystems, in order to understand the effect of seasonality and of anthropic alterations to the surrounding environment on the Odonata community.
