    Abstract : In host-parasitoid systems, there is a continuous coevolutionary arms race where each species imposes a strong selection pressure on the other. The host needs to develop defence strategies in order to escape parasitism and the parasitoid must evolve counter-defence strategies in order to overcome the host’s immune defence and successfully reproduce.

    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
