García-Berthou, E., Almeida, D., Benejam, Ll., Magellan, K., Bae, M.-J., Casals, F., Merciai, R. 2015. Ecological impact of inland fish introduced to the Iberian Peninsula. Ecosistemas 24(1): 36-42. Doi.: 10.7818/ECOS.2015.24-1.07

The Iberian Peninsula has a rich fauna of freshwater fish, with many endemics that are threatened. One of the threat causes is the introduction of exotic species or translocation of natives to new basins. In this paper, we review the ecological impacts of these introductions, from the genetic and individual to the community and global levels, primarily using studies from the Peninsula. Although the accumulated evidence is considerable, the ecological impact of most species and introductions has barely been studied and is probably much greater than is known.
