    Ecomorfologia trófica de Acarichthys heckelii (Müller & Troschel, 1849), Heros efasciatus Heckel, 1840 e Mesonauta insignis (Heckel, 1840) (Perciformes:Cichlidae) nas reservas de desenvolvimento sustentável de Amanã e Mamirauá, Amazônia

    The cichlids are one of the most diverse families of living freshwater fishes, about 1.900 species. A. heckelii, H. efasciatus and M. insignis are exploited at the Sustainable Development Reserves of Amanã and Mamirauá according to sustainable management plan. A free-size canonical variable analysis was made to investigate the ecomorphological patterns of variation among the three species from Amanã and Mamirauá Reserves. The three species formed different groups like species, ontogeny phase and habitat. Those groups were divided as result of characters like mouth width and head length. Differences among juveniles and adults were significant in relative area of eye and aspect-ratio of caudal fin. The diet composition indicated that three studied species have a converged feeding habit on insects in both black and white waters habitats.
