Is There Life After Death? The Role of Standing Dead Phorophytes in Supporting Tropical Epiphyte Diversity

Biotropica, Volume 58, Issue 4, July 2026.
ABSTRACT Global increases in tree mortality from climate change and land‐use are altering forest structures, impacting canopy‐dwelling plants like vascular epiphytes, which depend on host trees (phorophytes). When a phorophyte dies standing, it becomes a snag, the local substrate conditions change and microclimatic exposure may increase, particularly ...

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 ...

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

Semina: 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.

Análise de crescimento do capim-Mombaça em sistema silvipastoril e monocultura manejados sob diferentes alturas do dossel

Revista de Ciências Agroveterinárias
O presente trabalho teve como objetivo avaliar as características de crescimento do capim-Mombaça em sistemas silvipastoril e monocultura sob diferentes alturas do dossel. Os sistemas avaliados foram de monocultura e silvipastoril com diferentes estratégias de manejo de corte que foram 70, 80, 90 e 100 cm, respectivamente em dois períodos do ano ...

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

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

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

Functional 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

Insect 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.
