1. Ecological and Evolutionary Consequences of Herbivory in the Perennial Herb Lythrum salicaria
Abstract : In this thesis, I combined field, common-garden and greenhouse experiments to examine the ecological and evolutionary consequences of plant-herbivore interactions in the perennial herb Lythrum salicaria. More specifically I examined (1) whether resistance and tolerance to damage from herbivores vary with latitude and are positively related to the intensity of herbivory in natural populations, (2) whether effects of herbivory on plant fitness vary with latitude, (3) whether populations are locally adapted and whether herbivory influences the relative fitness of populations, and (4) whether the intensity and effects of insect herbivory on reproductive output vary locally along a disturbance gradient and are associated with differences in plant resistance.

2. Coevolution and molecular background of species interactions in geographic mosaics
Abstract : In complex food webs, species often interact with each other indirectly through mediating species. As a result of geographic mosaic of coevolution, such interactions are often evolutionarily unstable and the traits governing the interaction sometimes vary over time. READ MORE
