I am evolutionary ecologist and my research focuses on the phenomenon of genetic polymorphism and its potential drivers: parasites. My research combines experimental and field approaches, as well as analysis of molecular markers. As a model system, I am using water fleas of the genus Daphnia, and their various Ext. Link microparasites.

Why don’t populations/communities consist solely of the fittest genotype/species? Any common genotype is at a strong disadvantage because parasites adapt to this common host and, consequently, drive its frequency down. Thus, hosts and parasites could enter into a never-ending cycling of genotypes leading to the long-term maintenance of genetic polymorphism in both the host and parasite populations. Although such Red Queen dynamics were originally considered to operate only among genotypes within a single species, I am also looking for the evidence of parasite-driven frequency dependent selection in hybridizing systems, i.e. between parental and hybrid taxa. In existing literature the differences in infection levels between parental species and hybrids are considered to be fixed. My research challenges this idea as we’ve found that within the Daphnia hybridizing complex, the species that was rare and under-infected increased in frequency and subsequently became over-infected ( Wolinska et al. 2006). I believe that coevolutionary oscillations generated by frequency-dependent selection might provide a better explanation for the infection patterns than does a static genetic perspective of host resistance ( Wolinska et al. 2008).
