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 کاملDatura stramonium poisoning in children.
Although substance abuse is fairly common among adolescents, poisoning from Datura stramonium (a broadleaf annual erect herb with spine-covered seed capsule) is uncommon in children and has not been reported in our locality. We present the case of two children admitted at the Children Emergency Room of a teaching hospital following ingestion of extract of Datura stramonium. They developed neuro...
متن کاملNatural selection drives chemical resistance of Datura stramonium
Plant resistance to herbivores involves physical and chemical plant traits that prevent or diminish damage by herbivores, and hence may promote coevolutionary arm-races between interacting species. Although Datura stramonium's concentration of tropane alkaloids is under selection by leaf beetles, it is not known whether chemical defense reduces seed predation by the specialist weevil, Trichobar...
متن کاملPoisoning by Datura (Stramonium)— Recovery
partaken of a quantity of datura leaves, prepared in the form of curry, with rice, which he afterwards acknowledged to have voluntarily taken. On admission, he lay perfectly unconscious, with severe spasmodic muscular twitchings and stertorous breathing. Skin cool; pulse about 108?, feeble. Pupils dilated and insensible to the effects of light. The stomach pump was immediately introduced, but d...
