Mapping the density of giant trees in the Amazon

open access: yesNew 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 ...

Peregrinação : possibilidades de compreensão crítica de uma experiência [PDF]

open access: yes, 2012
This study inquires about the several possibilities of critical understanding of the – human and religious – experience of pilgrimage. After exploring the polarity present in the very idea of “experience” as conceived by the technical and scientific ...

Growth–survival trade‐off in temperate trees is weak and restricted to late‐successional stages

open access: yesJournal of Ecology, Volume 113, Issue 11, Page 3466-3477, November 2025.
Our findings highlight a role of disturbances in filtering life‐history strategies and their potential impact on forest dynamics and global carbon cycling, but also a need to better understand the mediating processes of tree demographic trade‐offs.

A construção do sentido e da compreensão na conversa, mostrada em procedimentos meta-enunciativos

open access: yesLinha D'Água, 2012
Quando duas pessoas conversam, elas necessariamente tratam de um tema, isto é, falam sobre um assunto ou sobre alguém. Por isso se diz que a conversa é uma interação tematicamente centrada. Cada falante envolvido numa conversa, ao se manifestar e, assim,

Effects of Long‐Term Nutrient Addition on Leaf Metabolites, Herbivory, and Mycorrhizal Spores Associated With a Savannah Woody Species

open access: yesAustral Ecology, Volume 50, Issue 11, November 2025.
ABSTRACT Given the importance of soil conditions for ecosystem functioning, fertilisation experiments are a valuable tool for assessing how systems respond to changes in soil properties. However, the effects of changes in nutrient availability on multitrophic interactions in savannah ecosystems of the Brazilian Cerrado are still scarce. We investigated

Seasonal and intracanopy shifts in the fates of absorbed photons in central Amazonian forests: implications for leaf fluorescence and photosynthesis

open access: yesNew Phytologist, Volume 248, Issue 1, Page 76-91, October 2025.
Summary Recent studies have shown a linear relationship between solar‐induced Chl fluorescence (SIF) and gross primary productivity (GPP) at large scales. However, this relationship diverges at finer leaf scales, particularly in tropical forests with complex canopy structures.

Microbial drivers of root plasticity

open access: yesNew Phytologist, Volume 248, Issue 1, Page 52-67, October 2025.
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...
