Revista de Arqueologia, 1994 Carajás representa um papel fundamental para a compreensão da integração humana na Amazônia. Isto acontece devido às suas características ambientais e às possfveis inteirações que os homens puderam ter com elas. Inclusive, como conseqüência disto, é posslvel esboçar uma hipótese testável, sobre a formação e evolução das culturas amazônicas, cujas ...

The Holocene, 2012 Patterns of endemism in the Neotropics have been explained by restriction of forest to ‘refugia’ in arid cold-stages of the Quaternary (Haffer J (1969) Speciation in Amazonian forest birds. Science 165: 131–137). The palaeoecological record, however, shows no such forest contraction.

The Anatomical Record, EarlyView.We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy
The Anatomical Record, EarlyView.Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.
