| evidence for rapid evolutionary change in an invasive plant in response to biological control. | we present evidence that populations of an invasive plant species that have become re-associated with a specialist herbivore in the exotic range through biological control have rapidly evolved increased antiherbivore defences compared to populations not exposed to biocontrol. we grew half-sib families of the invasive plant lythrum salicaria sourced from 17 populations near ottawa, canada, that differed in their history of exposure to a biocontrol agent, the specialist beetle neogalerucella calma ... | 2017 | 28370749 |
| indirect effects of herbivory on plant-pollinator interactions in invasive lythrum salicaria. | herbivory can affect a plant's fitness in a variety of ways, including modifying the biotic interactions of the plant. in particular, when herbivory influences floral display, we hypothesize that pollinator visitation will be altered accordingly. here we studied the indirect effects of feeding by two beetles, neogalerucella calmariensis and n. pusilla, released as a biological control, on plant-pollinator interactions and fitness in the invasive plant, purple loosestrife (lythrum salicaria). | 2015 | 26022480 |
