Tiny predators avoid herbivorous caterpillar traces to prevent accidental predation
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 ...

Evaluación del agregado de taninos en dietas de alimentación a corral de bovinos para carne
El tratamiento con taninos condensados ha sido sugerido como recurso para reducir la degradabilidad ruminal de las proteínas de origen vegetal y mejorar la eficiencia de uso de las proteínas en las dietas de bovinos. El presente trabajo evaluó durante 92

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

A Generalized Framework for Flow Resistance in Canopies and Granular Beds
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
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

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 ...

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.
