First Record of Brazil nut Pollinators Outside Amazon Biome

Floresta e Ambiente, 2022
We present the first records of insect visitors and pollinators of Bertholletia excelsa (Lecythidaceae) in a 25 years plantation outside the Amazon biome, flowering and producing Brazil nuts. We installed a platform to observe and photograph the insects.

Interaction between floral rewards and floral symmetry shapes diversification dynamics in Amazonian trees. [PDF]

New Phytol
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 ...

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 ...
