Although gene flow was identified between lakes and nearby stream populations, there was a low percentage of dispersers, and the paedomorphic populations were genetically differentiated from the populations of metamorphs. It is likely that the studied lakes have offered peculiar conditions that have allowed the development of a paedomorphic phenotype. These populations and phenotypes therefore constitute good models to understand local adaptations. As each of these populations of paedomorphs can be considered evolutionary significant units that cannot be replaced by other nearby populations in case of a population crash, conservation actions should be focused directly on them.

Las especies exóticas más vendidas como animales de compañía son las que más posibilidades tienen de ser liberadas en la naturaleza por sus dueños y, por ende, convertirse en especies invasoras, según un estudio publicado en el Journal of Applied Ecology y realizado por la Universidad Rutgers (Universidad Estatal de Nueva Jersey).
