Assessing reproductive isolation using a contact zone between parapatric lake-stream stickleback ecotypes.

abstract：:It has often been argued that evolutionary diversification is the result of divergent natural selection for specialization on alternative resources. I provide a comprehensive review of experiments that examine the ecology and genetics of resource specialization and adaptive radiation in microbial microcosms. In these ...
