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

New Phytol
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 frequency and importance of polyploidy in tropical rainforest tree radiations. [PDF]

New Phytol
Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...

Effect of the Soil Matric Potential on the Germination Capacity of Prosopis chilensis, Quillaja saponaria and Cryptocarya alba from Contrasting Geographical Origins

Plants, 2022
As a consequence of the megadrought in Central Chile, it is expected that most of the distribution of woody species will be narrowed in the northern limits because of restrictions imposed by soil matric potential on seed germination.

Toward a functional understanding of novel fire regimes in tropical forests. [PDF]

Am J Bot
Abstract Climate change and land‐use alterations are driving forest fires to unprecedented frequencies and intensities worldwide. Even wet tropical forests—historically rarely subjected to fire—are increasingly experiencing fire disturbances. The impact of wildfires on these forests is likely large, since many of their tree species are not adapted to ...
