Local adaptation in host-parasite systems

Article Abstract:

Parasites have an advantage in coevolutionary arms races. Researchers investigated the advantage and how adaptation and counter-adaptation of parasites and hosts can generate a pattern of local adaptation. In metapopulations, such factors as extinction, recolonization, gene flow, variable selection pressure, and stochasticity could change adaptation levels. Researchers concluded that local adaptation is a local phenomenon. Its detection would require appropriate replication at the right level, that at which the local processes occur.

Host and parasite population structure in a natural plant-pathogen system

Article Abstract:

The relationship between the host plant Silene latifolia and its fungal pathogen Microbotryum violaceum, both of the Rhine Valley, has been investigated. The hosts in this system have been shown to be obligate outcrossers, migrating by seeds and pollen, while the parasites can self-fertilize and migrate only through pollinating insects. These parasite populations are 12 times more differentiated than their hosts.
