I’m Dan Li from China. Now I’m working in the Population Biology Group at the University of Amsterdam as a postdoc.
My project is about the indirect effects of predators on the competitive interactions of native and invasive herbivores. When invasive herbivores enter a new habitat, they may interact with native species in a direct way through exploitative competition or indirectly through the shared host plants or shared predators. Sometimes, the native predators cannot control the invasive herbivores as well as the native ones, thus helping the invasive species to establish in the new habitat or even facilitating their competition with native species. Feeding on invasive species like the spider mite Tetranychus evansi, the native predators do not perform well, which may have a potential influence on their behaviors. To investigate whether the predators promoted the successful invasion of the invasive spider mite in Europe, we are now working on a predatory mite (Phytoseiulus persimilis) and two spider mite species (Tetranychus urticae and Tetranychus evansi).
