Mapping the density of giant trees in the Amazon [PDF]
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 [PDF]
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 ...

Caatinga diaspores: Descriptive overview of dispersal units of seasonally dry tropical forests and woodlands [PDF]
Ecology, Volume 106, Issue 2, February 2025.Abstract Dispersal unit characteristics provide crucial insights into species ecology and are essential for the conservation and restoration of ecosystems. The Caatinga, the largest ecosystem of seasonally dry tropical forests and woodlands in South America, remains underrepresented in terms of dispersal unit data, which are often scattered across the ...

Across the edge: Spatial segregation drives community structure in tri‐trophic multilayer networks at a forest–grassland edge [PDF]
Journal of Animal Ecology, Volume 94, Issue 11, Page 2205-2219, November 2025.This study reveals how forest–grassland edges act as ecological barriers that shape tri‐trophic interaction networks. Using multilayer network theory, it uncovers how species influence and biodiversity patterns emerge across spatial layers, offering novel insights into edge‐driven community assembly and conservation in fire‐prone mosaics.

Experimental Drought Suppresses Amphibian Pathogen Yet Intensifies Transmission and Disrupts Protective Skin Microbiome [PDF]
Global Change Biology, Volume 31, Issue 6, June 2025.This study used ecologically realistic enclosures with pumpkin toadlets to simulate short‐term drought conditions in Brazil's Atlantic Forest. Drought reduced the overall levels of a harmful amphibian fungus, but it also disrupted their protective skin‐associated bacteria and caused the toadlets to cluster in wet areas of the enclosures, which ...

Towards a global understanding of tree mortality [PDF]
New Phytologist, Volume 245, Issue 6, Page 2377-2392, March 2025.Summary Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground‐based long‐term forest monitoring with large‐scale remote sensing.
