Road Blockades During the Pandemic: Indigenous Citizenship and New Territoriality
Area, Volume 58, Issue 1, March 2026.Short Abstract In the Peruvian Amazon, the blocking of land and river routes has become an increasingly common strategy among indigenous groups to exercise active citizenship. The adoption of this protest tactic during the pandemic raises two central questions: First, what socio‐political and cultural factors shaped this collective action? Second, what

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest
Biotropica, Volume 58, Issue 2, March 2026.We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.

Biotropica, Volume 58, Issue 2, March 2026.Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy‐derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over

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 ...

Insect Conservation and Diversity, Volume 19, Issue 2, Page 404-419, March 2026.Habitat transformation in Amazon due to agriculture expansion impairs Melolonthidae diversity. Assemblage response towards habitat transformation are group‐dependent. Although highly disturbed, Amazon arc of deforestation region dwells sensitive insect assemblages. Abstract Although the Amazon provides crucial goods and ecosystem services for humanity,

Genetic diversity of Bertholletia excelsa, an Amazonian species of wide distribution [PDF]
BMC Proceedings, 2011 Background Amazonian upland forests are expansive and can comprise large continuous tracts. There have been several studies on the population genetic structure of species in this kind of forest, but there are few studies that aim to understand genetic structure throughout the Amazon [1].
