Efeito do pulso de inundação na riqueza, abundância e composição de formigas em florestas alagáveis no Rio Juruá, Carauari, Amazonas

Abstract

Flood forests in the Amazon, permanently flooded areas or seasonally due to the flood pulse or the flood and drought process of the great rivers, cover about 30% of the Amazon region, or approximately 1.7 million square kilometers. Consequently, understand how the species are distributed and how they respond to the flood pulse is fundamental to understanding how ecosystem processes affect the diversity in the Amazon forests as a whole. The purpose of this work is understand how the richness, abundance and composition of arboreal ants and that live in shrubs are modified by the flood pulse of the Juruá River to the during a hydrological cycle. The ants were collected in the Reserva de Sustainable Development (RDS) Uacari and the Extractive Reserve (RESEX) Middle Juruá, in terra firme area and floodplain area. The collection of ants was based on the use of tree traps and the tapping of understory vegetation. The samples are in the Animal Biology Laboratory of the Federal University of Amazons, being sorted and quantified. So far, the collections carried out in the drought (September/2014) have already been cleaned and during the flood (March/2015) they have already been sorted and counted; resulting in approximately 3,365 ants. The next step will be to identification of all species.
