Tracking the origin of an invasive species: Drosophila subobscura in Argentina

Mostrar todas las versiones(3)

Biological invasions are excellent opportunities to study the evolutionary forces leading to the adaptation of a species to a new habitat. Knowledge of the introduction history of colonizing species helps tracking colonizing routes and assists in defining management strategies for invasive species....
