Combined phylogenies: hosts and their parasites

Hosts and their parasites are prominent model systems for studying coevolutionary processes. A fundamental problem in the theory of comparing host-parasite phylogenies is the reconstruction of past associations between hosts and parasites. Event based methods for solving the reconstruction problem take advantage of knowledge about the likelihood of possible evolutionary events. In this talk, we give a short overview over event-based methods for the reconstruction problem, and present a tool that we have developed for solving this problem when extinction events are possible.
