Caracterizaçao dos taninos da aroeira-preta (Myracrodruon urundeuva) [PDF]

Revista Árvore, 2002
Visando contribuir para a caracterização química de uma madeira nobre nativa e em extinção no Brasil, no presente trabalho estão apresentados os estudos de identificação e quantificação dos taninos da aroeira-preta (Myracrodruon urundeuva), uma espécie da família Anacardiaceae. Este estudo foi conduzido com base nos extratos acetona-água (AA) e metanol-

Analytical Model of Velocity Distribution and Penetration Characteristics in Water‐Level Fluctuation Zone With Vegetation

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract As a critical ecological transition zone between aquatic and terrestrial ecosystems, the water‐level fluctuation zone significantly influences flow structure through vegetation morphology. Conventional analytical velocity models inadequately address the variation in vegetation with water depth.

Microtubule Inhibitors Induce Cross‐Resistance to Osimertinib Through CaMKII Activation in EGFR‐Mutated NSCLC

Cancer Science, Volume 117, Issue 2, Page 418-428, February 2026.
Eighteen‐week treatment with microtubule inhibitors induces resistance to osimertinib in EGFR‐mutated NSCLC cells. Vinorelbine‐ and paclitaxel‐resistant cells showed activation of FZD7 and CaMKII and increased sensitivity to CaMKII inhibition, with additive or synergistic effects when combined with osimertinib.

Scale Effects of Patch Configuration and Density on Vegetation Drag in Floodplain Flows

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT Vegetated floodplains modulate river hydraulics through drag forces that affect flow conveyance, sediment transport and floodplain ecosystems. Non‐uniform vegetation patches are widespread in natural floodplains and challenge drag prediction models, as the scale‐dependent effects of patch configuration, canopy density and submergence remain ...

Photoperiod–Temperature Interactions in a Changing Climate: A Review of Plant Phenological Responses

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Climate change is reshaping plant phenology and species distributions, especially in temperate and boreal ecosystems, where advances in spring events have already extended the growing season. While temperature has been the primary focus of many studies, the role of photoperiod—a stable, latitude‐dependent cue—remains underexplored.

Submerged Flexible Canopies Produce Weaker Shear‐Layer Turbulence and Mitigate Sediment Transport, Compared to Rigid Model Canopies

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Submerged vegetation canopies are widespread and influence bedload sediment transport in rivers, wetlands and deltas. However, the impacts of submerged canopies on sediment transport have not been fully quantified. This study used model Vallisneria denseserrulata to construct submerged flexible canopies in a mobile bed.
