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 ...

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.

Hepaticae of Cerro Venamo, Venezuela, collected by J. Steyermark [PDF]
A revision of herbarium material (NY) from Cerro Venamo, Venezuela (5°59’ N, 61°23’ W, 1890 m) yielded 77 hepatic species in 44 genera and 13 families. Most species have a neotropical distribution (75,32%), 6,49%, are pantropical and 9,09% are reported ...

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 ...

Mammal predator and prey species richness are strongly linked at macroscales [PDF]
Predator-prey interactions play an important role for species composition and community dynamics at local scales, but their importance in shaping large-scale gradients of species richness remains unexplored.
