1. Distribution extension of Phimophis guerini (Serpentes: Dipsadidae: Xenodontinae) in the Brazilian Amazon
ABSTRACT Phimophis guerini Duméril, Bibron & Duméril, 1854 is a Xenodontinae snake distributed in Argentina, Brazil and Paraguay. In Brazil, the species is broadly distributed, occurring mainly in open areas of the Cerrado, but also in the Amazon, Atlantic forest and Caatinga. We provide a new record for this species from the municipality of Santarém in t

2. Nesting biology of three Megachile (Hymenoptera: Megachilidae) species from Eastern Amazonia, Brazil
Abstract Megachile Latreille is a conspicuous genus of solitary bees distributed worldwide. However, the biology of tropical species is still little known. We present data on biology of Megachile brasiliensis Data Torre, Megachile sejuncta Cockerell and Megachile stilbonotaspis Moure found in two remnants of eastern Amazonian forest in northeastern Brazil.

3. Palm species richness, latitudinal gradients, sampling effort, and deforestation in the Amazon region
ABSTRACT Palms are most diverse in warm and humid regions near the equator. Though palms remain relatively well conserved, they are under increasing pressure from deforestation. Here, we analyze patterns of palm species richness relative to latitudinal gradient, sampling effort, and deforestation in the Amazon, and compare patterns of richness and floristic

4. SPECIES DIVERSITY AND COMMUNITY STRUCTURE OF FRUIT-FEEDING BUTTERFLIES (LEPIDOPTERA: NYMPHALIDAE) IN AN EASTERN AMAZONIAN FOREST
RESUMO O desmatamento tem impactos negativos na diversidade e padrões de comunidades de diversos taxa. Na Amazônia Oriental, onde um grande desmatamento é previsto para os próximos anos, manchas florestais podem ser essenciais para manter a biodiversidade local. Apesar de crescente preocupação quanto à conservação de áreas ameaçadas, poucos estudo

5. Socio-economic and spatial determinants of anthropogenic predation on Yellow-spotted River Turtle, Podocnemis unifilis (Testudines: Pelomedusidae), nests in the Brazilian Amazon: Implications for sustainable conservation and management
Human expansion has drastically affected wildlife species across Amazonian waterways and the continued increase in rural populations across Amazonia is likely to increase pressure on widely exploited chelonian species. The lack of information evaluating determinants of human consumption patterns limits the effective implementation of conservation strategies.

7. Impacts of hydroelectric dams on alluvial riparian plant communities in eastern Brazilian Amazonian
Os principais rios da bacia Amazônia e sua biota estão ameaçados pelos planos de construção de grandes usinas hidrelétricas que poderá causar fortes impactos nas comunidades vegetais das áreas alagadas. O objetivo desse estudo é apresentar os inventários botânicos em três áreas de vegetações inundadas dos rios Tocantins, Xingu e Tapajós no le

8. Mosquitoes of eastern Amazonian Ecuador: biodiversity, bionomics and barcodes
Two snapshot surveys to establish the diversity and ecological preferences of mosquitoes (Diptera: Culicidae) in the terra firme primary rain forest surrounding the Tiputini Biodiversity Station in the UNESCO Yasuní Biosphere Reserve of eastern Amazonian Ecuador were carried out in November 1998 and May 1999. The mosquito fauna of this region is poorly know

11. Sand flies (Diptera: Psychodidae) in a cerrado area of the Maranhão state, Brazil
The present paper aims to increase the knowledge on the sand fly fauna in the cerrado areas of Maranhão state in urban, rural and forest environments. The research was carried out from October 2007 to September 2008, between 18:00h and 06:00h, in the municipality of Chapadinha, northeast Maranhão. For insect sampling, CDC light traps were set up in peridom

12. Geocronologia e evolução tectônica paleo-mesoproterozoica do oriente boliviano - região sudoeste do craton amazônico / Paleo-mesoproterozoic Tectonic Evolution and Geocronology of Eastern Bolivia, SW Amazonian Craton
This work characterizes the tectonic and magmatic evolution of the Precambrian shield of Bolivia. The complex geological evolution of the eastern Bolivia extends from the Paleo- to Mesoproterozoic, and can be related with the magmatic and metamorphic events that are ascribed to the Rio Negro - Juruena (1.78-1.60 Ga), Rondonian - San Ignacio (1.56-1.30 Ga) an
