The Adaptation of Soy-corn Double-cropping to the Brazilian Savanna

open access: yes, 2019
TWO REMARKABLE innovations have enabled Brazilian farmers to compete with the soy and corn exports of their US counterparts—breeding soybean varieties for low latitudes using biological nitrogen fixation (BNF) (Hungria, Campos, and Mendes 2001; Alves ...

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, Volume 168, Issue 3, Page 972-984, July 2026.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

The Role of Gene Flow in the Diversification of the Monkey Treefrog Complex Across the South American Dry Diagonal

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 568-588, July 2026.
ABSTRACT Understanding Neotropical megadiversity remains challenging due to fundamental taxonomic issues, including identifying and describing cryptic species and their distribution, and the limited knowledge of key factors driving biological diversification. Such challenges are especially prominent in diverse clades with high levels of cryptic species,

Strong Sensitivity of Simulated Biomass Burning Aerosol Transport and Radiative Effects Over the South Atlantic to Carbonaceous Aerosol Aging and Particle Density

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Biomass burning aerosol (BBA) impacts climate through aerosol‐cloud‐radiation interactions, but models disagree on the sign and magnitude of BBA radiative effects. We quantify the sensitivity of BBA radiative effects and transport to three BBA‐relevant processes and properties: parameterized oxidative aging of organic aerosol (OA), a combined ...

Impacts of Deforestation‐Driven Rainfall Reductions on Amazonia Forest Stability

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The stability of Amazonian vegetation is strongly influenced by land–atmosphere feedbacks. It has been hypothesized that deforestation‐induced precipitation decline may lead to widespread forest decline across the entire basin. Using a moisture‐tracking model, we quantify how deforestation across South America alters downwind rainfall and ...

Ground-dwelling ant Assemblages and Soil Attributes Relationship in Roraima Savanna, Brazilian Amazon

open access: yes
Ants are among the most abundant soil invertebrates and provide important ecosystem services. We evaluated the relationship between ant assemblages and soil attributes in a Brazilian savanna area within the Amazon biome (Roraima State).
