Phenotypic and genetic differentiation between diadromous and landlocked puyen Galaxias maculatus
This study reports the phenotypic and genetic differences between individuals of puyen Galaxias maculatus from two sites in the same river basin in Tierra del Fuego National Park, southern South America. Individuals from the two sampling sites presented morphometric and genetic differences. The morp...
