Estudo da distribuição espacial e temporal de macroinvertebrados nos campos de reflorestamento de mangal em Icídua

Abstract

In order to understand the structure of the benthic macroinvertebrate community present in the Mangrove Reforestation Fields in Icidua, the spatial and temporal distribution of these Benthic Organisms can vary with the life cycle phase and be associated or not in space. In this context, a study was developed involving aspects presented in this work, with the following objectives: 1. To estimate the specific composition of the macroinvertebrates in the fields of reforestation of Icidua and 2. To determine the horizontal and temporal distribution pattern of Benthic Macroinvertebrates. square method that were defined by the points of interception of a grid formed by transepts traced perpendicular to the coastline in relation to each block and transepts traced parallel to the coastline in relation to each block. The distance between the perpendicular and parallel transepts for each block was 50 meters and 40 meters forming a grid, and in the intercession of parallel and perpendicular transepts form a subplot. The results show that areas with greater vegetation were found to have a larger number of organisms than to areas with lower vegetation. It also shows that the species with the highest number of representative was Uca dussumieri, followed by Cerithidea decollata, and the species with the lowest number It is concluded that the present study shows the importance of the conservation of aquatic environments as well as coastal ecosystem since the maintenance of terrestrial biodiversity to the different characteristics of the present sediment and the amounts of vegetation considered in this study had an influence mainly on the distribution of organisms with abundance in areas of greater amounts of vegetation, It was recommended that for the recovery of degraded areas, there should be creation of working groups involving actors capable of working with the community, should be preceded by hydrological studies in order to have the viability and sustainability of the reforestation.
