Abstract

Morphological characters are essential to analyze fishes assemblages structures. The ecological morphology considers the interaction between organisms endogenous factors and the environmental characteristics where they live. Its identify differences ecological and adaptive strategies. The morfospaces techniques analyze the structure of a fish assemblage through the values of the intervals between homologous points (or landmarks), positioned in structures of different organisms phylogenetically related. These intervals are quantified by geometric morphometrics and multivariate analyzes. The technique has been used to measure the variability of biodiversity in time and space. Morphogeometrics indices characterize the general shape of the body, head, eyes, mouth, and the position and length of the fins, providing an assemblages structure photography and inferences about the ecological and evolutionary structural processes. Besides, it allows to detect ecological and/or anthropogenic disturbance, through the reduction of morphological variability according to the configuration of morphoespaces. The Araçá Bay, although impacted, sustains the life of organisms rarely represented in other coastal environments at the same region and due to its specific conditions, many species live there in abundant.
