DESMATAMENTO DA AMAZÔNIA BRASILEIRA
, 2021 Este artigo buscou mostrar fatos atuais do desrespeito ao desmatamento da Amazônia e ressalta a importância de se tomar atitudes enquanto ao tema, para que o futuro seja saudável para a vida no planeta. Foi realizado com base nos eventos recentes de degradação da Floresta Amazônica e a demonstração de falta de atenção ao tema e a preservação ...

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 ...

Traumatismo raquimedular e desmatamentos na Amazônia
JBNC - JORNAL BRASILEIRO DE NEUROCIRURGIA, 2003 Morbidity and mortality of spinal cord injured patients (SCI) in the Brazilian Amazon region is reviewed. In deforestation places this kind of injury is usually caused by the fall of cut trees over the victim. Deforestation activity is usually illicit and worker’s protection and safety are unsatisfactory.

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

Biotropica, Volume 58, Issue 1, January 2026.Subtropical Highland Grasslands showed greater net conversion than Mixed Ombrophilous Forest across our study PAs. In one PA created to conserve Highland Grasslands, net grassland loss inside the PA exceeded loss in adjacent buffer zones during the study period.

Habitat Amount Shapes Ant Diversity in the Central Amazon
Biotropica, Volume 58, Issue 1, January 2026.Ant diversity in fragmented Amazonian forest landscapes is primarily driven by landscape‐scale habitat amount rather than fragment size, supporting the Habitat Amount Hypothesis (HAH) over Island Biogeography Theory (IBT). Consequently, conservation strategies should prioritize maintaining and restoring forest cover across human‐modified landscapes ...

Integrative Conservation, Volume 4, Issue 4, Page 546-554, December 2025.Desertification is increasing in the Brazilian Semiarid, leading to loss of species and ecosystem services, while precise data on biodiversity distribution and trends are lacking. Public engagement in scientific projects can improve ecosystem protection.
