Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

Slow Recovery and Loss of Species Richness in a Semi‐Deciduous Seasonal Atlantic Forest After Selective Logging and Drought Events

open access: yesJournal of Vegetation Science, Volume 37, Issue 3, May/June 2026.
Long‐term monitoring revealed slow recovery and declining species richness in a semi‐deciduous Atlantic Forest following selective logging and recurrent droughts. Despite structural increases, compositional shifts toward dominance by a few species indicate functional simplification.

Water stress and temperature on germination and vigor of Handroanthus impetiginosus (Mart. ex DC)

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental
Water availability and temperature are among the main abiotic factors that influence seed germination and vigor, since they act directly on biochemical and physiological processes, which result in the production of the primary root. The objective of this

Assembling the Neotropical Tree Flora: Andean Uplift and the Historical Biogeography of the Brazil Nut Family (Lecythidaceae)

open access: yesJournal of Biogeography, Volume 53, Issue 4, April 2026.
ABSTRACT Aim The assembly of tropical tree floras is complex, involving many lineage‐specific histories; however, focusing on the biogeographic history of diverse clades can reveal general patterns. We investigated the historical biogeography of the ecologically important Brazil nut clade (Lecythidoideae) to: (1) expand prior phylogenies with greater ...

Convergence and parallelism in the evolution of plant metabolism

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 4, Page 1013-1031, April 2026.
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...
