PRODUTIVIDADE EM CASCA E TANINOS CONDENSADOS DE JUREMA-PRETA [PDF]

Nativa, 2015
Espécie vegetal de ampla distribuição geográfica no bioma Caatinga, a Mimosa tenuiflora (Willd.) Poir., vem sendo explorada, principalmente, para produção de energia, apesar de possuir considerável teor de taninos. Com base nisto, no presente estudo analisou-se a produtividade da espécie em relação à produção de casca e seu rendimento em taninos ...

Flexible patchy vegetation in a meandering bend: Effect on main flow and dispersion processes

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
The presence of finite flexible and submerged vegetation patches in bends alters the typical curvature‐induced circulation motion and the streamwise velocity distribution, determining a fragmented flow patternThe lateral dispersion and the mass exchanges are strongly influenced by the vegetated patches and turbulent structures forming in patch‐adjacent

Field measurements and model predictions of turbulent kinetic energy in canopies of sparse vegetation under tidal flows

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract The presence of vegetation in aquatic environments alters hydrodynamics and sediment resuspension. A recent paradigm has suggested that turbulent kinetic energy (TKE) serves as a better predictor of sediment transport in aquatic canopies than bed shear stress.

Longitudinal Mean Velocity and Turbulent Kinetic Energy Within an Emergent Canopy in Nonuniform Flows

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Vegetation‐induced drag generates nonuniform water surface profiles through flow disruption, creating complex hydrodynamic conditions characterized by enhanced turbulence and energy dissipation. This study investigates the longitudinal velocity and turbulent kinetic energy (TKE) dynamics in emergent canopies under streamwise varying flow ...

Preservación de madera con taninos

Madera y Bosques, 2016
En este trabajo se exponen tres ideas para la aplicación de taninos contra posibles agentes destructores de madera. Se hace una descripción somera de los mecanismos naturales de defensa de los árboles con el fin de tratar de empezar a comprenderlos. Estos mecanismos ocurren como consecuencia de estímulos o ataques externos.

Cold hardiness mechanisms and modeling: existing approaches and future avenues

New Phytologist, Volume 249, Issue 6, Page 2668-2682, March 2026.
Summary Cold hardiness models are useful tools to predict cold damage in plants, such as those produced by unseasonal temperature cycles or by increased cold exposure. Although development of these models started about five decades ago, their applications remain limited.

Contrasting effects of experimental warming in the initiation year and the flowering year on flower phenology of boreal understory species

American Journal of Botany, Volume 113, Issue 2, February 2026.
Abstract Premise High‐latitude plants initiate flower primordia at least 1 year before flowering. While impacts of rising temperatures on phenology in the flowering year are well studied, the effects of warmer temperatures in the initiation year (IY; the year before flowering) are virtually unknown.
