Minimum number of measurements for evaluating Bertholletia excelsa.

Genetics and molecular research : GMR, 2017
Repeatability studies on fruit species are of great importance to identify the minimum number of measurements necessary to accurately select superior genotypes. This study aimed to identify the most efficient method to estimate the repeatability coefficient (r) and predict the minimum number of measurements needed for a more accurate evaluation of ...

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.

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 ...
