Efecto antidiarreico del polvo de hojas de Anacardium occidentale L. en aves neonatales

open access: yesRevista de Producción Animal, 2017
Para evaluar el efecto antidiarreico del polvo de hojas de Anacardium occidentale L., se utilizaron 45 pollitas White Leghorn (Híbrido L-33), de dos días de edad, durante 8 horas. Se aplicó un diseño totalmente aleatorizado, con tres tratamientos.

Metabolic modeling identifies determinants of thermal growth responses in Arabidopsis thaliana

open access: yesNew Phytologist, EarlyView.
Summary Temperature is a critical environmental factor affecting nearly all plant processes, including growth, development, and yield. Yet, despite decades of research, we lack the ability to predict plant performance at different temperatures, limiting the development of climate‐resilient crops.

Off‐target drift of the herbicide dicamba disrupts plant–pollinator interactions via novel pathways

open access: yesNew Phytologist, EarlyView.
Summary While herbicide use in agriculture is expected to have many effects on surrounding weed communities, it is largely unknown how plant exposure to sublethal doses of herbicide may subsequently impact plant–pollinator interactions. We tested the hypothesis that sublethal herbicide exposure indirectly alters plant–pollinator interactions through ...

Field plants strategically regulate water uptake from different soil depths by spatiotemporally adjusting their radial root hydraulic conductivity

open access: yesNew Phytologist, EarlyView.
Summary Plants modify their root hydraulics to maintain water status and strategically use soil water, but how they achieve this in the field conditions remains elusive. We developed a method to measure and calculate daily root water uptake, root water potential, and radial root water permeability at different depths in a wheat (Triticum aestivum L ...

Relaciones filogenéticas de la subtribu Oncidiinae (Orchidaceae) inferidas a partir de caracteres estructurales y secuencias de ADN (ITS y matK): un enfoque combinado Phylogenetic relationships of the subtribe Oncidiinae (Orchidaceae) inferred from structural and DNA sequences (matK, ITS): a combined approach

open access: yesRevista Mexicana de Biodiversidad, 2010
Para conocer el valor que los caracteres estructurales tienen para la reconstrucción filogenética de la subtribu Oncidiinae se realizó un análisis de parsimonia combinado con base en datos anatómico foliares, morfológicos y secuencias de ADN de las ...
