Mapping the density of giant trees in the Amazon

New Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Interaction between floral rewards and floral symmetry shapes diversification dynamics in Amazonian trees

New Phytologist, Volume 248, Issue 6, Page 3297-3311, December 2025.
Summary Floral zygomorphy, or monosymmetry, is thought to have a positive effect on the diversification rates of angiosperms, but its true impact is still an open topic. Given the controversy surrounding this matter, our study evaluates whether rewards such as nectar and pollen produced by floral structures evolve in correlation with floral symmetry ...

Efficient Extraction of Phenolic Compounds From Cariniana rubra Gardener Ex Miers From the Legal Amazon: Ultrasound‐Assisted Optimization, Chemical Characterization, and Antioxidant Potential

Chemistry &Biodiversity, Volume 22, Issue 11, November 2025.
ABSTRACT Cariniana rubra, native to the Brazilian Cerrado and the Amazon‐Cerrado ecotone, is traditionally used in folk medicine but remains underexplored. This study optimized extraction yield and bioactive compound content using ultrasound‐assisted extraction (UAE) and Soxhlet extraction.
