Filogenia das espécies de Deuterodon Eigenmann, 1907 (Characiformes: Characidae), um gênero de lambaris da Mata Atlântica

Abstract

Aos meus pais que incentivaram e acompanharam cada passo dessa evolução. Que com muita luta deram-me a possibilidade de estudar. Dedico... "Estou quase convencido de que (completamente contrário à opinião de quando comecei) as espécies não são-e isso é tal como uma confissão de um assassinato-imutáveis." "I almost convinced (quite contrary to opinion I started with) that species are not (it is like confessing a murder) immutable." Charles Darwin Agradecimentos Gostaria de agradecer a todos que direta e/ou indiretamente contribuíram para a realização desse trabalho. A todos minha sincera gratidão. Primeiramente gostaria de agradecer ao Prof. Dr. Ricardo M. C. Castro pela confiança e amizade concedida durante esse pouco tempo de convívio. Além da orientação despendida, num tema que eu ainda não dominava, confiou e mostrou-me os caminhos da dissecção de peixes e da filogenia dos caracídeos. A FAPESP (Fundação de Amparo à Pesquisa do Estado de São Paulo) pela bolsa de mestrado (proc. 08/52379-5) concedida durante o desenvolvimento desse trabalho. Ao Prof. Dr. Ricardo Cardoso Benine, por me apresentar ao Prof. Ricardo Castro, iniciando, uma nova etapa da minha carreira acadêmica.

Cytogenetic and Molecular Data SuggestDeuterodon pedriEigenmann, 1907 (Teleostei: Characidae) Is a Member of an Ancient Coastal Group

“…8 These results also contradict the statement of Pereira that D. pedri and D. parahybae are more related to each other than to other species of the genus. 60 The molecular data also recover close phylogenetic relationship of some Astyanax species with Deuterodon in the clade 2, representing, in general, the clade 57 in Oliveira et al topology. 3 In the COI tree, clade 3 is composed of species with highly variable dentitions.…”

“…72 In the temporal scale, the similarity of ichthyofauna between coastal and continental basins can be explained by Cretaceous vicariant events (pattern A), tertiary cladogenetic events (pattern B), and most recent vicariant events (pattern C). 60 The pattern B is defined by phylogenetic relationship to the level of genera, between sister-groups of the endemic ichthyofauna of Brazilian coastal basins and adjacent shields, in which, in some cases, both clades underwent subsequent radiation. 60 The genetic similarity between S. typhlops and other species in the clade 3 of the COI tree suggests an ancient geographic connection between the São Francisco and Doce basins.…”

The distribution pattern of Mimagoniates species along coastal drainages has been explained by sea eustatic alterations, and its relationship with its sister-group, the Glandulocauda genus, which is endemic of Brazilian southeastern crystalline shield, can be included in the pattern B of phylogenetic divergence.…”
