Mid-Holocene vegetation dynamics with an early expansion of Mauritia flexuosa palm trees inferred from the Serra do Tepequém in the savannas of Roraima State in Amazonia, northwestern Brazil
Transition zones between forest and savanna in northern South America are important areas for improving our understanding of ecosystem dynamics and climate change. The uniquely available mid-HoloceneExpand

Forest stability during the early and late Holocene in the igapó floodplains of the Rio Negro, northwestern Brazil
Abstract Located at the northwestern part of the Amazon basin, Rio Negro is the largest black-water river in the world and is one of the poorest studied regions of the Amazon lowlands. In theExpand

Vegetation changes and human impact inferred from an oxbow lake in southwestern Amazonia, Brazil since the 19th century
Abstract Pollen and X-ray fluorescence spectrometry (XRF) analyses from a 272 cm-long sediment core of Lago Amapa, an oxbow lake in western Amazonia, reveal the first palaeoecological investigationExpand

Ecosystem services show variable responses to future climate conditions in the Colombian páramos
Background The páramos, the high-elevation ecosystems of the northern Andes, are well-known for their high species richness and provide a variety of ecosystem services to local subsistence-basedExpand
Forest-savanna boundary shift on the plateau of Serra Sul dos Carajás (southeastern Amazonia) since the mid-Holocene; driving forces and limiting factors
Abstract The vegetation history of the savanna on the plateau of Serra Sul dos Carajas (PSSC) is well studied by three palynological records. Nonetheless there is no record from the forests aroundExpand

Shut down of the South American summer monsoon during the penultimate glacial
We analysed changes in mean annual air temperature (MAAT), vegetation and biomass burning on a long and continuous lake-peat sediment record from the Colônia basin, southeastern Brazil, examining theExpand

Chronostratigraphy of a 1.5±0.1 Ma composite sedimentary record from Colônia basin (SE Brazil): Bayesian modeling based on paleomagnetic, authigenic 10Be/9Be, radiocarbon and luminescence dating
We present a new 52 m composite record (COL17c) composed of five sedimentary sequences retrieved from the Colonia basin (Southeastern Brazil). The COL17c record is composed of two main sub-unitsExpand
