Abstract excerpt
Co-evolutionary theory proposes that polymorphisms in co-evolved traits may be maintained through differential selection in spatially heterogeneous environments. Spatial heterogeneity of the schistosome intermediate host, Biomphalaria pfeifferi, was investigated here, using RAPD markers. Overall, 256 individuals, collected at 32 sites on 13 rivers in the Chiweshe region of Zimbabwe, were analysed. Significant...
