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 ...

Composite design bioinspired by the mesocarp of Brazil nut (Bertholletia excelsa)
Bioinspiration & Biomimetics, 2022 Abstract The mesocarp of Bertholletia excelsa is a rich source of inspiration for strong, stiff and damage-tolerant composites. The bioinspired composites developed here are composed of an epoxy matrix with a 3D printed polylactic acid reinforced with 30% of carbon fiber (PLA-30CF) inspired in fibers, and syntactic foam inspired by ...
