1. ESTRATIGRAFIA GPR E MORFOGÊNESE QUATERNÁRIA NO SEMIÁRIDO BRASILEIRO
Resumo O Parque Nacional da Serra da Capivara desponta como estudo de caso para pesquisas do Quaternário e de geomorfologia no nordeste semiárido brasileiro. Trabalhos anteriores no vale da Serra Branca, uma das principais unidades geomorfológicas do parque, revelam o predomínio de espessos depósitos coluviais, sugerindo flutuações climáticas episód

2. A Serra da Capivara e os primeiros povoamentos sul-americanos: uma revisão bibliográfica
Resumo A área da Serra da Capivara (Piauí, Brasil) é famosa na comunidade arqueológica internacional, principalmente pela polêmica ao redor do sítio Pedra Furada e de suas datas do Pleistoceno superior, fazendo dele um dos sítios mais antigosdas Américas. Os dados oriundos deste sítio contribuem indiscutivelmente nas discussões e nos conhecimentos

3. Cordão Formation: loess deposits in the southern coastal plain of the state of Rio Grande do Sul, Brazil
ABSTRACT Loess consists of silt-dominated sediments that cover ~10% of the Earth's surface. In southern South America it occurs in Argentina, Bolivia, Paraguay and Uruguay, and its presence in southern Brazil was never studied in detail. Here is proposed a new lithostratigraphic unit, Cordão Formation, consisting of loess deposits in the southern Brazilian

4. The Late Holocene upper montane cloud forest and high altitude grassland mosaic in the Serra da Igreja, Southern Brazil
Muitos solos dos picos da Serra do Mar, como em muitas outras serras, apresentam horizontes hísticos espessos com elevados estoques de carbono. No entanto, a idade e constituição da matéria orgânica destes solos ainda é pouco conhecida e não se sabe se é predominantemente proveniente de comunidades de plantas do final do Pleistoceno ou do Holoceno.

5. Megafauna do quaternário tardio dos depósitos cársticos do Alto Vale do Ribeira, sudeste do Estado de São Paulo, Brasil / Late-Quaternary megafauna of the Upper Ribeira karstic area, southeast São Paulo State, Brazil
The carbonate caves of the Upper Ribeira Valley, southeastern São Paulo State, Brazil, preserve abundant fossil record of Pleistocene-Holocene South American megafauna. This work presents a historical review of its paleontological studies, as well as an update taxonomic survey of the megafauna material gathered since the beginning of the explorations in the

6. Petrogêneses do complexo vulcânico Yate (42, 30ºS), Andes do Sul, Chile / Petrogenesis of the Yate Volcanic Complex (42, 30ºS), Andes Southern, Chile
The Yate Volcanic Complex (CVY) is located in the Southern Volcanic Zone of the Chilean Andes, at 42°30S, comprising the Yate, Gualaihué and Hornopirén volcanoes. The Yate volcano is a major compound type in which effusive activity occurred since Upper Pleistocene (c. 122 ka) until Holocene. Hornopirén and Gualaihué are minor, and represent strombilian-

7. Caçadores-coletores na Serra de Paranapiacaba durante a transição do Holoceno Médio para o Tardio (5920-1000 anos AP) / Hunter-gatherers from Parnapiacaba Mountains during the Middle Holocene to the Later Holocene transition (5920-1000 yr BP)
This thesis provides the results of an archaeological survey focused in hunter-gatherer settlements from Upper Almas valley, on the western side of Paranapiacaba Mountains. Dates from lithics analysis associated to these sites are compared with results from Middle Ribeira valley, developed by De Blasis (1988). In addition, this Thesis treats to establish fra

8. "Aplicação de marcadores orgânicos moleculares em estudos oceanográficos e paleoceanográficos: estudo de caso na Margem Continental Superior do Sudeste do Brasil" / Molecular Organic Markers Application in Oceanographic and Paleoceanographic Studies: Case study at the Southeastern Brazilian Continental Margin
Climatic changes produce environmental signatures with which it is possible to reconstruct past environmental conditions. In the ocean, the fate of most of the organic matter is the marine sediment. Sediment core analyses reveal a unique reservoir of biological, chemical and geological information about past processes and how they responded to the environmen

9. Benthic foraminiferal paleoecology of upper holocene of Sepetiba Bay, Rio de Janeiro / Paleoecologia de foraminíferos bentônicos do holoceno superior da baía de Sepetiba, Rio de Janeiro
This work was developed from analysis of benthic foraminifera associations encountered in Sepetiba Bay and Guaratiba Mangrove holocenic sediments. Sepetiba Bay is a semi-confined body of water, that is a part of Sepetiba- Guaratiba Coastal complex at Rio de Janeiro southwest. It has been used six cores from Guaratiba Mangrove and five cores from Sepetiba Bay

10. Litoestratigrafia e deformação cenzóica na região de Icapuí, Ceará, e implicações para a estruturação de campos de petróleo na borda ocidental da bacia Potiguar(NE do Brasil)
This thesis deals with the sedimentological/stratigraphic and structural evolution of the sedimentary rocks that occur in the NW continental border of the Potiguar Basin. These rocks are well exposed along coastal cliffs between the localities of Lagoa do Mato and Icapuí, Ceará State (NE Brazil). The sedimentological/stratigraphic study involved, at the ou

11. Tetraploidía en Ceratophrys (Anura, Leptodactylidae), análisis del registro fósil
It has been confirmed the existence of the tetraploid counterpart of the genus Ceratophrys Wied, 1824 (extint at the present time) in Argentina and Brazil since the Pliocene, and the apparition of the octaploidy in the Upper Pleistocene - Holocene. Fossil material of the diploid form, distinctive of the Chacoan District, has been reported from the horizons o

12. Behavioral inferences from the Skhul/Qafzeh early modern human hand remains
Two groups of humans are found in the Near East ≈100,000 years ago, the late archaic Neanderthals and the early modern Skhul/Qafzeh humans. Observations that Neanderthals were more heavily muscled, had stronger upper-limb bones, and possessed unusual shapes and orientations of some upper-limb joint complexes relative to the Skhul/Qafzeh hominids, have
