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

open access: yesGlobal 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

open access: yesJournal 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

open access: yesGlobal 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.

Ad maiorem Dei gloriam: Numeracy levels in the Guarani Jesuit missions

open access: yesThe Economic History Review, Volume 76, Issue 1, Page 87-117, February 2023., 2023
Abstract This work provides data on human capital for the Guarani Jesuit missions during the eighteenth century. Based on the age heaping methodology, the results of a large sample (over 3600 observations) suggest that the knowledge of numerical skills in these missions was exceptional.

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

open access: yesGlobal 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.
