These animals have been in full evolutive process due to their capacity of reproducing and adapting to different habitats. Philogeneticly, the group still hasn't a sure characteristic and is very similar morphologically to rodents Sigmodontinae from Serra dos Carajás. Through this study of external features and some banes from post-cranium related to motions habit, we beheld: 1) The choice of the habitat in Serra dos Carajás area among the rodents seems not to be related to a phylogenetic standard; 2) It wasn't possible to set a relationship between ecological features and main morphological shape from post-cranium related to body-shape among Sigmodontinae; 3) the morphology of úmero and femur have a strong Phylogenetic sign which is another feature of subfamily Sigmodontinae; 4) the signs intermembal, crural e branquial weren't effective to identify the many way of motions among the rodents Sigmodontinae.porAcesso AbertoMamíferosMamífero roedorSigmodontinaeFilogenéticaDiferenciação sexualMastofaunaOsteologiaSerra dos Carajás - PAPará - EstadoAmazônia brasileiraDissertaçãoCNPQ::CIENCIAS BIOLOGICAS::ZOOLOGIA::MORFOLOGIA DOS GRUPOS RECENTES
