title: Natural hybridization in freshwater animals. Ecological implications and molecular approaches.
abstract: The number of cases where the phenomena of hybridization and gene introgression have been found in species interactions is steadily increasing, in both plant and animal taxa. During the last few years, many examples have been detected even in otherwise well-known freshwater animal taxa. We discuss the topic with respect to ecology and evolutionary processes and compare the main potentials and limitations of allozymes, mitochondrial DNA, and RAPD markers to address some important genetic issues of interspecific hybridization in natural populations of selected freshwater model systems.
