Abstract

Ecological interactions are among the main drivers of biodiversity. Organisms of all taxa are necessarily involved in different types of interactions which can potentially promote diversification and reciprocal changes in interacting species, i.e. coevolution. Understand which mechanisms underlie coevolutionary processes is essential to develop accurate predictions about biological systems. Interactions between parasitoids and their hosts represent an ideal system to understand coevolutionary dynamics and for the elaboration and test of hypotheses regarding the role of coevolution on biological diversity. The goal of this project is to investigate the underlying mechanisms and processes that drive the development of defenses by hosts, and how parasitoids counteract such defenses. The reciprocal influence of interaction patterns and the underlying coevolutionary mechanism ultimately promote or constrain the diversity in this system. (AU)
