The Role of Phosphate Fertilization on Physiological Responses of the Young Bertholletia excelsa Plants Grown in a P-Deficient Amazon Ferralsol [PDF]

Plants, 2022
Phosphorus (P) reacts with soil minerals, which makes it less available to plants. Considering that Amazonian soils have a low pH and nutrient availability, both of these properties contribute to an increase in P limitation.

Nut production in Bertholletia excelsa across a logged forest mosaic: implications for multiple forest use [PDF]

PLoS One, 2015
Although many examples of multiple-use forest management may be found in tropical smallholder systems, few studies provide empirical support for the integration of selective timber harvesting with non-timber forest product (NTFP) extraction.

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

New Phytologist, Volume 248, Issue 6, Page 3297-3311, December 2025.
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 ...

Barium Levels in Brazil Nuts: A Global Review of the Literature [PDF]

Journal of Food Science, Volume 90, Issue 11, November 2025.
ABSTRACT Brazil nuts are often recommended for their high selenium content but have also been reported to contain elevated levels of barium, a potentially toxic element. Regular daily consumption of Brazil nuts may exceed the currently suggested tolerable daily intake (TDI) for barium (ca. 0.2 mg/kg body weight/day).

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

New Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
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 ...

Insights From a New 1‐ha Permanent Forest Plot Reveal Differences Between Habitat Type and Similarities Between Forest Type in the Southwestern Amazon [PDF]

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Southwestern Amazon forests are highly diverse, but information on how tree diversity and composition changes between habitat and forest types remains scarce. We conducted floristic analyses to investigate these changes across a precipitation gradient, between habitat types, and between disturbed and old‐growth forest.

Morphological evaluation of Bertholletia excelsa comparing different methods [PDF]

Scientific Electronic Archives, 2020
 Castanheira-do-Brasil is a semi-deciduous species which belongs to forests made up of vegetation specific to the Amazon Forest biome. The objective of this work is to perform the leaf and adult morphometry of B. excelsa by the traditional method and to compare with image analysis processed using the ImageJ program.
