Habitat use patterns suggest that climate‐driven vegetation changes will negatively impact mammal communities in the Amazon

Animal Conservation, Volume 26, Issue 5, Page 663-674, October 2023., 2023
The southern border of the Amazon is threatened by climate and land use induced shifts from rainforest to savannah‐like habitat. We show that most terrestrial medium or large mammals in protected areas in the southern Brazilian Amazon react negatively in their space use to natural savannah habitat, including species considered habitat generalists.

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.

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.

Identifying genes associated with abiotic stress tolerance suitable for CRISPR/Cas9 editing in upland rice cultivars adapted to acid soils

Plant Direct, Volume 6, Issue 12, December 2022., 2022
Abstract Five genes of large phenotypic effect known to confer abiotic stress tolerance in rice were selected to characterize allelic variation in commercial Colombian tropical japonica upland rice cultivars adapted to drought‐prone acid soil environments (cv. Llanura11 and Porvenir12).

Biogeography of freshwater mussels (Bivalvia: Unionida) in Texas and implications on conservation biology

Diversity and Distributions, Volume 28, Issue 7, Page 1458-1474, July 2022., 2022
Abstract Aim Biogeography seeks to identify and explain the spatial distributions of species and has become an important tool used by conservationists to protect and manage aquatic organisms. Texas, located in the southwestern United States, is home to 52 species of freshwater mussels, 9 of which are endemic to Texas and 7 that are endemic to Texas and

Deforestation‐free land‐use change and organic matter‐centered management improve the C footprint of oil palm expansion

Global Change Biology, Volume 28, Issue 7, Page 2476-2490, April 2022., 2022
Alternative land‐use changes like degraded savannas conversion holds potential to replace tropical deforestation and its pernicious effect on ecosystem aspects. However, lack of empirical evidence hinders the understanding of the impacts of such alternative pathway for sustainable agricultural development on important ecosystem processes. Here, we show

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.

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 ...

Long‐term jaguar demography underscores the ecological value of Amazonian floodplains

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results provide the first estimates of recruitment and apparent survival for Amazonian jaguars, key parameters for guiding conservation. We show that seasonal wetlands—the Amazonian floodplain forest and reported estimates from Pantanal and the Llanos—harbour the highest jaguar densities across the species' range.

Flood Modelling Evaluation in a Semiarid Catchment: The Role of a Soil Mineralogical Index From Satellite Imagery

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.
ABSTRACT The Mediterranean region is characterized by the occasional occurrence of intense rainfall events. Along with lithological, geomorphological, and land use factors, these events influence the hydrosedimentary dynamics of drainage basins, potentially causing torrential floods.
