Adaptive divergence in resistance to herbivores in Datura stramonium
Defensive traits exhibited by plants vary widely across populations. Heritable phenotypic differentiation is likely to be produced by genetic drift and spatially restricted gene flow between populations. However, spatially variable selection exerted by herbivores may also give rise to differences among populations. To explore to what extent these factors promote the among-population differentia...

متن کاملEvolutionary Ecology of Datura Stramonium L. in Central Mexico: Natural Selection for Resistance to Herbivorous Insects.
It has been assumed that herbivores constitute a selective agent for the evolution of plant resistance. However, few studies have tested this hypothesis. In this study, we look at the annual weed Datura stramonium for evidence of current natural selection for resistance to herbivorous insects. Paternal half-sib families obtained through controlled crosses were exposed to herbivores under natura...
متن کامل[Intentional Datura stramonium intoxication: an unknown etiology of mydriasis].
Two case reports of Datura stramonium intoxications are presented. The first one was a self poisoning, with a moderate anticholinergic syndrome and a spontaneous improvement. The second one was a recreational use of Datura stramonium for its hallucinogenic properties. The anticholinergic syndrome was marked and the improvement required orotracheal intubation, mechanical ventilation, intraveinou...
