INTRODUCTION
The need for an integration of population ecology and population genetics has been repeatedly recognized (Levin and Udovic 1977, Lewontin 1979, Antonovics and Via 1988). Studies of disease demonstrate the necessity of linking numerical and genetic studies. For instance, diseases can have profound effects on numbers of hosts but the outcome of any particular interaction will depend greatly on the genotypes of hosts and pathogens present. In agriculture, crop failures and successes often depend on whether cultivars (analogous to host genotypes) are resistant or susceptible to the pathogens present. Research on plant-pathogen interactions in natural systems ...
