13. Re-examining the hypothesis of allopatric distribution of Myoprocta acouchy and M. pratti (Mammalia: Dasyproctidae) in South America
Currently, two allopatric species of acouchies, genus Myoprocta (Rodentia: Dasyproctidae) are recognized. Nevertheless, there is morphological variability in the regions where the species are distributed that suggests either sympatry of two (or more) distinct species or else breakdowns in the characters that have been used to diagnose the species. We reviewe

14. Raposa Serra do Sol : agentes políticos, conflitos e interesses / Raposa Serra do Sol : political agents, conflicts and interests
The aim of this work is to map the multiple political actors involved in the demarcation of the Indian region named Raposa Serra do Sol (TIRSS), contemplating each actor s arguments, and to analyze the political conflicts generated by this issue. By studying this demarcation process that lasted three decades, we tried to successfully relate the domestic poli

15. Amblyomma dissimile Koch (Acari: Ixodidae) attacking Primolius maracana Vieillot (Psittaciformes: Psittacidae) in the Amazon region, state of Pará, Brazil
The tick Amblyomma dissimile Koch feeds preferentially on reptiles (Squamata), although amphibians (Anura) also seem to be important hosts. We report an A. dissimile nymph infesting a blue-winged macaw, Primolius maracana, held in captivity in the Mangal das Garças Park, State of Pará, Brazil. Environmental observations suggest that free-living iguanas (Ig

16. ASPECTOS ECOLÓGICOS DO CERVO DO-PANTANAL Blastocerus dichotomus (ILLIGER, 1815) (MAMMALIA: CERVIDAE): ANIMAIS REINTRODUZIDOS E OU NASCIDOS NA ESTAÇÃO ECOLÓGICA DE JATAÍ, NORDESTE DO ESTADO DE SÃO PAULO, MUNICÍPIO DE LUÍS ANTÔNIO / ECOLOGICAL ASPECTS OF MARSH DEER Blastocerus dichotomus (ILLIGER, 1815) (MAMMALIA: CERVIDAE): ANIMALS REINTRODUCED AND OR BORN IN THE ECOLOGICAL STATION OF JATAÍ, NORTHEAST OF THE STATE OF SÃO PAULO, CITY OF LUIS ANTONIO
Marsh deer (Blastocerus dichotomus) is a large mammal and is considered the largest deer native to South America, this species is extinct in 60% of its historic range that included the natural flood plain of the great rivers between the southern Amazon and northern Argentina. Despite being threatened with extinction, little is known about the ecological aspe

17. Avaliação do impacto das condições hídricas do solo no início da estação chuvosa de 2004/2005 / Evaluation of the hydric soil conditions role on the 2004/2005 rainy season onset
Some studies have been showed that the surface heat fluxes are important to the monsoon system around the world. The importance of the soil moisture on seasonal forecasts has also been pointed out. Therefore, the influence of the soil moisture on the early stages of the South America (SA) monsoon system was the aim of this study. Moreover, it is aimed to kno

18. Molecular Systematics and Biogeography of Monogenoidea (Platyhelminthes: Cercomeromorpha), Gill Parasites of Potamotrygonidae (Chondrichthyes: Rajiformes: Myliobatoidei) / Sistemática molecular e biogeografia dos Monogenoidea (Platyhelminthes: Cercomeromorpha), parasitas das brânquias de Potamotrygonidae (Condrichthyes: Rajiformes: Myliobatoidei)
South America is the only biogeographical region in the world where is possible to find an exclusive stenohalin group of elasmobranchs: the Potamotrygonidae stingrays. Between 19 and 21 species of potamotrygonid stingrays are taxonomically organized in three genera, distributed in the Atrato, Magdalena, Maracaibo, Orinoco, Essequibo, Amazonas e la Plata rive

19. Estudo epidemiológico da infecção por herpesvírus 8 humano (HHV-8) em população indígena da Amazônia brasileira / Epidemiological study of Human herpesvirus 8 infection (HHV-8) in the Amerindian population from Brazilian Amazon
The human herpesvirus 8 (HHV-8) is endemic in Africa and Amerindian populations from Amazon region. The infection in those populations occurs during childhood and, in Africa, involves a close contact in intrafamilial environment. Several studies confirm the geographical distribution of different subtypes of HHV-8, and the subtype E is typical of the Amerindi

20. Desenvolvimento sustentável, cultura e alteridade :um estudo a partir das comunidades indígenas da Amazônia
One of the goals of modern science was to dissolve myths and replace the imaginary by knowledge, illustrating the thesis that man s superiority lies in his ability to rule in practice over Nature. The role of the human being and the visibility of horizontal communications among different markets, particularly the center-periphery relationship, however, raise

22. Relações entre a mineralogia, fertilidade, acidez e macrofauna em latossolos do cerrado sob pastagem
The Cerrado region occupies approximately 24% of Brazilian territory, making it the second biggest biome in South América, exceeded only by the Amazon Rainforest. The majority of the soils of the region were described as being acid, with a low capacity for cation exchange and high saturation by aluminium. Pastures cover 117 million hectares, of which 54 mil

23. Cytogenetic study of the giant otter Pteronura brasiliensis Zimmermann 1780 (Carnivora, Mustelidae, Lutrinae)
The giant otter, Pteronura brasiliensis Zimmermann 1780 (Carnivora, Mustelidae, Lutrinae), was widely distributed in South America but stable populations are now only found in the Pantanal and Amazon regions and the species is classified as endangered. There is only one recognized species of giant otter, although two subspecies of doubtful value have also be

Caracterização e estimativa de biomassa em fitofisionomias de terra-firme da amazônia central por inventário florístico e por textura de imagens simulação do mapsar (Multi-Application Purpose SAR) / Phytophysionomic characterization and biomass estimation of a central amazon upland forest from floristic inventory and texture of images from simulated mapsar (Multi-Application Purpose SAR)
Sob a premissa de que nas florestas de terra firme da Amazônia Central a variação florística e estrutural sofrem influência do relevo e da proximidade da rede de drenagem, este estudo teve o objetivo de: 1) descrever a composição florística e a estrutura horizontal e vertical ao longo da toposequência; 2) desenvolver modelos preditivos de biomassa a
