Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin

Sedimentology, EarlyView.
ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

New Phytologist, Volume 251, Issue 1, Page 179-190, July 2026.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

Reducing Nitrogen Fertilizer Dependency in Tropical Pastures Through Azospirillum Brasilense and Pseudomonas Fluorescens Coinoculation

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Coinoculation with Azospirillum brasilense and Pseudomonas fluorescens was associated with maintained forage productivity under reduced nitrogen (N) fertilizer rates in tropical pastures. This hypothesis was evaluated in a 2‐year field experiment conducted over two consecutive growing seasons (2022 and 2023) the State University of Goiás, São Luís de ...

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change

Global Change Biology, Volume 32, Issue 4, April 2026.
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Alterations in plant architecture and physiology allow maize to sustain yield after early defoliation

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Maize (Zea mays L.) tolerance to early defoliation is shaped by genotype‐specific physiological and morphological responses. Defoliation disrupts the source–sink balance, altering carbon allocation and plant development. Understanding these responses is crucial for optimizing breeding programs and agronomic management.
