Large Methane Emissions From the Pantanal During Rising Water‐Levels Revealed by Regularly Measured Lower Troposphere CH4 Profiles

Global Biogeochemical Cycles, Volume 35, Issue 10, October 2021., 2021
Abstract The Pantanal region of Brazil is the largest seasonally flooded tropical grassland and, according to local chamber measurements, a substantial CH4 source. CH4 emissions from wetlands have recently become of heightened interest because global atmospheric 13CH4 data indicate they may contribute to the resumption of atmospheric CH4 growth since ...

Vulnerability of the biota in riverine and seasonally flooded habitats to damming of Amazonian rivers

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 31, Issue 5, Page 1136-1149, May 2021., 2021
Abstract The extent and intensity of impacts of multiple new dams in the Amazon basin on specific biological groups are potentially large, but still uncertain and need to be better understood. It is known that river disruption and regulation by dams may affect sediment supplies, river channel migration, floodplain dynamics, and, as a major adverse ...

Short communication: Estimating radiocarbon reservoir effects in Bolivian Amazon freshwater lakes [PDF]

Geochronology
The Llanos de Moxos, in the Bolivian Amazon, preserves a remarkable archaeological record, featuring thousands of forest islands. These anthropogenic sites emerged as a result of activities of the earliest inhabitants of Amazonia during the Early and ...

Aves de rapina diurnas em Llanos de Moxos, Bolívia [PDF]

, 2021
Raptor abundance has been poorly documented in the Neotropics. Here we describe the abundance and composition of the diurnal bird raptor community of Llanos de Moxos, one of the largest and less studied Neotropical savannah.

Extreme flood events in the Bolivian Amazon wetlands

Journal of Hydrology: Regional Studies, 2016
Study region: The Amazonian wetlands of Bolivia, known as the Llanos de Moxos, are believed to play a crucial role in regulating the upper Madeira hydrological cycle, the most important southern tributary of the Amazon River. Because the area is vast and

Alluvial plain dynamics in the southern Amazonian foreland basin [PDF]

Earth System Dynamics, 2016
Alluvial plains are formed with sediments that rivers deposit on the adjacent flood-basin, mainly through crevasse splays and avulsions. These result from a combination of processes, some of which push the river towards the crevasse threshold, while ...

Leaf phenology amplitude derived from MODIS NDVI and EVI: Maps of leaf phenology synchrony for Meso‐ and South America

Geoscience Data Journal, Volume 7, Issue 1, Page 13-26, June 2020., 2020
Monitoring and understanding the variation of ecosystem leaf phenology is vital for the dynamic global vegetation modelling community concerned with the representation of plant functional types. Here, the ecosystem leaf phenology of Meso‐ and South‐America has been characterised using MODIS NDVI and EVI 2000‐2013 time‐series.
