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

Processing, characterization and stability of Brazil nut (Bertholletia excelsa) extract
Research, Society and Development, 2020 The aim of this work was to obtain Brazil-soluble Brazil nut extract on a pilot scale, to determine the physical-chemical, microbiological, sensory and rheological characteristics of the products obtained and to determine the microbiological, physical-chemical and physical stability of the extract in presence and absence light and preservatives.

Spatial Mismatches of Plant‐Pollinator Interactions Under Future Climate Conditions
Journal of Biogeography, Volume 53, Issue 4, April 2026.ABSTRACT Aim Global change could disrupt critical ecological interactions, especially if interacting species shift their geographic ranges at different rates or in different directions. Functional redundancy within generalized networks could make them more resilient to climate change than networks with highly specialized interactions.

Journal 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 ...
