Forest Reorganisation After Natural Disturbance: A Synthesis
Global Ecology and Biogeography, Volume 35, Issue 3, March 2026.ABSTRACT Aim Natural disturbances are intensifying under global change, yet a global synthesis of their effects on forest structure and composition remains lacking. We aimed to assess the prevalence of structural versus compositional changes and to identify common post‐disturbance reorganisation pathways across forest biomes.

Small understory trees increase growth following sustained drought in the Amazon
New Phytologist, Volume 249, Issue 6, Page 2787-2799, March 2026.Summary Droughts pose a major threat to the Amazon rainforest, yet the mechanisms enabling trees to maintain growth under prolonged drought remain poorly understood, particularly in the understory layer. We leveraged a 22‐yr Throughfall Exclusion (TFE) in a 1‐ha plot in eastern Amazonia, paired with a Control plot, to test whether small understory ...

Angewandte Chemie International Edition, Volume 65, Issue 9, 23 February 2026.The structure of the non‐canonical C16 sesquiterpene named hegelenether was revised to the structure of marxdiol, and its absolute configuration was assigned. Isotopic labeling experiments revealed the stereochemical course of the methyltransferase involved in its biosynthesis.
