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 ...

The Mycovirus Cryphonectria Hypovirus 1 Infects the Heterologous Host Fusarium oxysporum and Induces Hypovirulence

open access: yesPlant Pathology, Volume 75, Issue 1, January/February 2026.
The Cryphonectria parasitica hypovirus CHV1 efficiently replicates in the heterologous host Fusarium oxysporum, inducing clear hypovirulence, and has the potential to persist and spread in this pathogen by constant infections and re‐infections through hyphal anastomosis.

Downconversion Master Slave OCT With a Bidirectional Sweeping Laser

open access: yesJournal of Biophotonics, Volume 18, Issue 12, December 2025.
ABSTRACT This paper explores the challenges of signal processing when using optical coherence tomography (OCT) imaging instruments driven by asymmetric MHz bidirectional sweeping lasers. A downconversion master–slave (DMS) method is proposed as a viable alternative to the traditional OCT protocol.

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

open access: yesNew Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Biomass production of tropical trees across space and time: The shifting roles of diameter growth and wood density

open access: yesJournal of Ecology, Volume 113, Issue 11, Page 3141-3158, November 2025.
Diameter growth is an important and good indicator of forest carbon production. However, size‐related changes in wood density, which are usually neglected, are critical for accurate short‐ and long‐term carbon assessments, especially in tropical humid sites.

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.
