"Although conservation issues and economic costs produced by rabbits' introductions around the world are well known, there is a lack of systematic information about this regarding their closest relatives. Hares and rabbits share some biological traits which could make them successful invaders and profoundly change the invaded regions. Perhaps one of the most notorious effects (among the many that they produce), is that they constitute a new and abundant food resource to a wide variety of predators, ultimately changing biological communities," said co-author Dr. Facundo Barbar, of Universidad Nacional del Comahue, in Argentina. "Considering all introduced leporid species and their many effects on the ecosystems in crucial at the time of planning conservation strategies."
