These results indicate that both moth and plant populations are differentiated at the regional scale. South-east Brazil (150 km apart), we did not find evidence of local adaptation, although we did find interpopulational differences in herbivore performance, and a significant interaction between herbivore sex and plant Predator, the arctiid moth Utetheisa ornatrix, at different spatial scales. We investigated local adaptation in the alkaloid-bearing legume Crotalaria pallida and its seed Local adaptation has central importance in the understanding of co-evolution, maintenance of sexual reproduction,Īnd speciation.
