Palm community transects and soil properties in western Amazonia

Domestication of Peach Palm in Southwestern Amazonia

The peach palm (Bactris gasipaes Kunth) is the only Neotropical palm domesticated by Native Americans. Its place of origin as a crop (B. gasipaes var. gasipaes) has been debated for more than a century, with three hypotheses currently in discussion: southwestern Amazonia; northwestern South America; or multiple origins in the distribution of the wild relatives (B. gasipaes var. chichagui). The ...

Regionalism and Cultural Identity in Western Amazonia

Cover Page Footnote: Acknowledgments. This paper was first written for the conference “Comparative Arawakan Histories” organized by Jonathan Hill and Fernando Santos-Granero, held at the Smithsonian Tropical Research Institute in Panama in July 2000. I am grateful to all of the participants in that conference for their helpful comments on and generous tolerance of this marginal Aruan case. I am...

Soil and vegetation carbon stocks in Brazilian Western Amazonia: relationships and ecological implications for natural landscapes.

The relationships between soils attributes, soil carbon stocks and vegetation carbon stocks are poorly know in Amazonia, even at regional scale. In this paper, we used the large and reliable soil database from Western Amazonia obtained from the RADAMBRASIL project and recent estimates of vegetation biomass to investigate some environmental relationships, quantifying C stocks of intact ecosystem...

Miocene flooding events of western Amazonia

There is a considerable controversy about whether western Amazonia was ever covered by marine waters during the Miocene [23 to 5 Ma (million years ago)]. We investigated the possible occurrence of Miocene marine incursions in the Llanos and Amazonas/Solimões basins, using sedimentological and palynological data from two sediment cores taken in eastern Colombia and northwestern Brazil together w...
