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 ...

Amazonia 2040: Spatial‐explicit futures scenarios for the mosaic of protected areas in the Lower Rio Negro (MBRN), Brazil

Ecological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
Spatial‐explicit futures scenarios were applied in the Mosaic of Protected Areas of the Lower Rio Negro (MBRN), for co‐creating scenarios for the MBRN in the year 2040. Scenario making enabled negotiating desirable futures, aligning values and goals.

Aflatoxins in raw Brazil nut (Bertholletia excelsa H.B.K.)

Journal of Agricultural Studies, 2023
The Brazil nut is a nutritionally rich food, produced and consumed in tropical regions. On the other hand, it may be suitable to toxigenic fungi and consequently contamination by aflatoxins (AFL), toxic substances to consumers. In this context, the objective of this work was to evaluate the occurrence of AFL in raw Brazil nuts, that is, before being ...

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.

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

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 ...

Compounds from Brazil nuts and their effects on Sitophilus zeamais (Coleoptera: Curculionidae) survival in bulk ground feed [PDF]

Brazilian Journal of Biology
Sitophilus zeamais is a pest in several stored agricultural products, but presents difficulty feeding on Brazil nuts (Bertholletia excelsa H.B.K). Even when certain bulk bran feeds are unsuitable for its development, it may be found in these products ...
