Landscape features predict broad‐scale seed rain patterns across fragments of the Brazilian Atlantic Forest

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Along with precipitation, forest cover emerges as a fundamental driver of alpha and beta diversity in the seed rain. This highlights the role of habitat amount at the landscape level over patch‐level features, like patch size, for seed dispersal. However, increased seed density can be related to higher dispersal rates in forest borders.

Recorte municipal do Sudeste e Sudoeste Paranaense: relação entre os fatores sociais e econômicos com o desflorestamento na Floresta Ombrófila Mista?

open access: yesRevista Espinhaço, 2014
É possível identificar as causas de desmatamento na Floresta Ombrófila Mista baseando-se em fatores econômicos e sociais da população? Estes fatores são equivalentes em áreas com diferentes taxas de desmatamento?

Traumatismo raquimedular e desmatamentos na Amazônia

open access: yesJBNC - 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.

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

open access: yesBiotropica, 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 ...

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): II. Solute Concentrations and Flux Dynamics

open access: yesBiotropica, 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

Temporal Changes in Land Use Highlight the Vulnerability of Highland Grasslands in Protected Areas in Southern Brazil

open access: yesBiotropica, 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

open access: yesBiotropica, 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 ...
