Abstract
In most types of freshwater ecosystems fish diversity depends greatly on land/inland water ecotones. So, to maintain biodiversity of fish communities in inland waters, management and restoration of aquatic terrestrial ecotones will be an important tool. However, to provide a scientific background for such conservation activities, it will be desirable to test the importance of different types of ecotones in structuring and maintaining the genetic diversity of fish populations. The relevance of population genetics data to ecotone studies can only be understood in an ecological context as evolution is a function of environment. We suggest that as ecotone complexity increases opportunities for survival of individuals, improving trophic conditions and spatial habitat heterogeneity, so the population size and variation increase with increased genetic diversity and vulnerability to environment changes decreases.
