Ichthyofauna (Osteichthyes, Actinopterygii) from tributaries of the Beni and Mamoré rivers in the Llanos de Moxos wetland of the Bolivian Amazon [PDF]

Check List
We conducted ichthyological surveys in the Biata, Geneshuaya, Benicito, and Yata Rivers, as well as Dos Naciones Lagoon. We recorded 182 species, including new records for Bolivia, such as Jupiaba citrina Zanata & Ohara, 2009, Moenkhausia ...

Geomorphology and evolution of the late Pleistocene to Holocene fluvial system in the south-eastern Llanos de Moxos, Bolivian Amazon [PDF]

CATENA, 2015
In the Bolivian Amazon several paleochannel generations are preserved. Their wide spectrum of morphologies clearly provides crucial information on the type and magnitude of geomorphic and hydrological changes within the drainage network of the Andean foreland.

Estimation de l'extension spatiale et de la variabilité temporelle des zones inondées dans les Llanos de Moxos (Amazonie bolivienne) [PDF]

, 2010
Les Llanos de Moxos sont une vaste zone d'inondation situées dans le sud du bassin amazonien et dans le nord de la Bolivie. Les inondations y ont une extension variable au cours de l'année, liée au régime tropical de la pluie ; ils s'assèchent en partie en hiver austral et peuvent atteindre des surfaces considérables, à la fin de la saison des pluies ...

Dispersal Across Headwaters Determines Fish Population Structure Between Interdigitating River Systems in the Guiana Shield Highlands. [PDF]

Ecol Evol
The genetic population structure of riverine fishes is strongly shaped by the architecture of dendritic river networks, which can shift over both contemporary and geological timescales. Such river rearrangements are rarely incorporated into models of riverscape genetics, but they can have a profound effect on fish populations, especially when formerly ...

Assessing Methane Emissions From Tropical Wetlands: Uncertainties From Natural Variability and Drivers at the Global Scale

Global Biogeochemical Cycles, Volume 37, Issue 9, September 2023., 2023
Abstract Methane (CH4) emissions from tropical wetlands represent half of the global wetland emissions, but uncertainties remain concerning the extent of tropical methane sources. One limitation is to conceive tropical wetlands as a single ecosystem, especially in global land surface models.

Differing local‐scale responses of Bolivian Amazon forest ecotones to middle Holocene drought based upon multiproxy soil data

Journal of Quaternary Science, Volume 38, Issue 6, Page 970-990, August 2023., 2023
ABSTRACT Uncertainty remains over local‐scale responses of ecotonal Amazonian forests to middle Holocene drying due to the scarcity, and coarse spatial resolution, of lacustrine pollen records. This paper examines the palaeoecological potential of soil phytoliths, stable carbon isotopes and charcoal for capturing local‐scale ecotonal responses of ...

Atmospheric Methane: Comparison Between Methane's Record in 2006–2022 and During Glacial Terminations

Global Biogeochemical Cycles, Volume 37, Issue 8, August 2023., 2023
Abstract Atmospheric methane's rapid growth from late 2006 is unprecedented in the observational record. Assessment of atmospheric methane data attributes a large fraction of this atmospheric growth to increased natural emissions over the tropics, which appear to be responding to changes in anthropogenic climate forcing.

Amazon fires in the 21st century: The year of 2020 in evidence

Global Ecology and Biogeography, Volume 31, Issue 10, Page 2026-2040, October 2022., 2022
Abstract Aim The aim was to evaluate fire activity for the entire Amazon and Amazon regions within each country/department from 2003 to 2020, assessing the potential contributions of drought and deforestation and contrasting 2020 with the previous years. Location Amazonia sensu lato. Time period Annually from 2003 to 2020.

Amazon Hydrology From Space: Scientific Advances and Future Challenges

Reviews of Geophysics, Volume 59, Issue 4, December 2021., 2021
Abstract As the largest river basin on Earth, the Amazon is of major importance to the world's climate and water resources. Over the past decades, advances in satellite‐based remote sensing (RS) have brought our understanding of its terrestrial water cycle and the associated hydrological processes to a new era.
