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

Trait coordination reveals the fast–slow plant economics spectrum along the vertical canopy profile in central Amazonian forests

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3596-3610, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding how environmental drivers affect tree functioning is essential to improve predictions of tropical forests' response to climate change. While functional traits directly influence tree performance, our understanding of how canopy environments shape their ...

Local and landscape features of urban fragments determine the occurrence of stingless bees As características locais e paisagísticas dos fragmentos urbanos determinam a ocorrência de uma espécie de abelhas sem ferrão

open access: yesInsect Conservation and Diversity, Volume 18, Issue 6, Page 1027-1036, November 2025.
Both local and landscape factors associated with habitat availability and quality determine the persistence of stingless bees across fragments. Places where the species occurs have local and landscape characteristics distinctive from those where it is absent.

Effect of post-grazing residual leaf blade-length on the regrowth vigor of Piatã grass grazed under intermittent stocking

open access: yesSemina: Ciências Agrárias, 2019
The objective of this study was to evaluate the effect of post-grazing residual leaf blades (RLB) of different lengths on the morphogenic and structural characteristics of Urochloa brizantha ‘Piatã’ grazed upon by beef cattle.

Perfilhamento, altura do dossel e cobertura do solo em pastagem de capim-elefante adubados com nitrogênio e irrigado

open access: yesBoletim de Indústria Animal, 2008
O experimento foi realizado em condições de campo com o objetivo de avaliar o efeito de quatro doses de nitrogênio (100; 300; 500 e 700kg ha-1de N) e seis lâminas de água (0, 20%, 40%, 80%, 100% e 120% da evapotranspiração) sobre a densidade populacional de perfilhos basais, altura e cobertura do solo pelo capim-elefante (Pennisetum purpureum ...

Impacts of fire on canopy structure and its resilience depend on successional stage in Amazonian secondary forests

open access: yesRemote Sensing in Ecology and Conservation, Volume 11, Issue 4, Page 394-410, August 2025.
We analyzed the effects of fire on secondary forests' vertical structure in different successional stages using lidar metrics. Our results show that independently of the successional stage, secondary forests that experienced fire were more degraded than unburned secondary forest areas. Overall, our results show that forests in early successional stage (
