Paleoenvironmental changes in a lower Rio Negro floodplain lake (Anavilhanas Archipelago, Brazil) during the past 4550 years
This study investigates Holocene climate variability and its influence on organic carbon accumulation patterns in the Anavilhanas Archipelago, Rio Negro, Brazilian Amazon. We analyzed a 404 cm sediment core from a floodplain lake to reconstruct paleoenvironmental changes and carbon storage dynamics over the last 4550 cal yr BP. The Middle to Late-Holocene transition (4550–4270 cal yr BP) was characterized by significant hydrological changes. Low …
Development of lacustrine primary productivity in the Amazon Basin during the Holocene
The Amazon Basin is one of the most productive regions in the world and an important carbon sink. However, lake productivity has varied throughout the Holocene, as preserved in lacustrine sedimentary records. Concentrations of chlorophyll pigmented derivatives that are mainly derived from phytoplankton and macrophyte populations can be used to infer lake production levels. Here we use the chlorophyll derivatives concentrations analyzed by spectro…
Late-Holocene palaeoenvironmental reconstruction from a lake in the Amazon Rainforest-Tropical Savanna (Cerrado) boundary in Brazil using a multi-proxy approach
As an ecotone, the region between the Amazon Rainforest and Tropical Savanna (Cerrado) biomes is, by definition, more susceptible to climate change. Therefore, understanding palaeoenvironmental dynamics is essential to address the future responses of such transition areas to climatic fluctuations. In this context, we present a new sediment record for the Late-Holocene retrieved from Barro-Preto, currently an oxbow lake located in an ecotone at th…
Forest stability during the early and late Holocene in the igapó floodplains of the Rio Negro, northwestern Brazil
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 the middle-upper part of the Rio Negro were retrieved sediment cores form Lake Acarabixi, which were analyzed using pollen, spores, charcoal, and geochemistry. The aim of this study was to detect the influences from humans and river dynamics on the vegetation history in …
Palaeohydrological controls on sedimentary organic matter in an Amazon floodplain lake, Lake Maracá (Brazil) during the late Holocene
In order to understand the impact of hydrological changes of the Amazon River on sedimentary organic matter (OM) composition in Amazonian floodplain lakes, three sediment cores were collected from Lake Maracá (eastern Amazonia) along a transect from the Amazon River main channel to inland. The cores were dated with 14 C accelerator mass spectrometry (AMS) and studied by x-ray, mineralogical composition, total organic carbon (TOC) and total nitrog…
