Tiny predators avoid herbivorous caterpillar traces to prevent accidental predation

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract We report the first example of predators having a strategy to avoid accidental predation by herbivorous insects. The predatory mites Neoseiulus womersleyi and Euseius sojaensis are smaller than 0.5 mm and lay eggs on plant leaf surfaces; thus, their immobile eggs would be incidentally consumed along with leaves by voracious lepidopteran ...

Tannins in Baccharis dracunculifolia (Asteraceae): effects of seasonality, water availability and plant sex Taninos em Baccharis dracunculifolia (Asteraceae): efeitos da sazonalidade, disponibilidade de água e sexo da planta

Acta Botânica Brasílica, 1999
Several ecological, genetic, and environmental factors are known to influence tannin concentration in plant tissues. In this study, the effects of seasonality, water availability, and sex of the plant on tannin concentration in the dioecious shrub ...

Development of Anti‐Inflammatory Extracellular Vesicles by Surface Expression of Syndecan‐4

Journal of Extracellular Vesicles, Volume 15, Issue 4, April 2026.
ABSTRACT The biological functions of extracellular vesicles (EVs) depend on their cellular source. Further, different subpopulations of EVs from the same cells carry different cargo, but differences in their biological functions are less understood. We here identify a very small EV subpopulation released by HEK293F cells (miniEVs).

Taninos da casca do Cajueiro: atividade antimicrobiana

Agropecuária Técnica, 2015
Os taninos são tóxico a muitos organismos inferiores causadores de doenças, como a bactéria Staphylococcus aureus que é o mais freqüente agente etiológico da mastite bovina. Este trabalho teve como objetivo determinar a atividade antimicrobiana in vitro das substâncias tânicas isoladas do caule do cajueiro (Anacardium occidentale Linn.) sobre linhagens

A Generalized Framework for Flow Resistance in Canopies and Granular Beds

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract This study presents a generalized, theoretically grounded semi‐empirical framework for estimating flow resistance through canopies and granular beds, both of which are common in engineering and environmental applications. Derived from fundamental fluid mechanics principles, the proposed formulation significantly reduces reliance on empirical ...

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 ...
