- Description:
- Number of migratory fish species, by freshwater ecoregion.
We derived the map of long-distance migrant (LDM) fish—the number of LDM species per ecoregion—from published literature, online databases (NatureServe), and expert inquiries. Potadromous, anadromous, amphidromous, and catadromous fish species were judged to be LDMs if they made regular journeys (i.e., for breeding, dispersal, feeding) of at least a hundred kilometers or more in freshwater. These species were then assigned to ecoregions based on the fish species lists database from Abell et al. (2008). Although we used many resources, two key data sources for the map were the following:
Carolsfeld, J., B. Harvey, C. Ross, and A. Baer, eds. 2003. Migratory Fishes of South America: Biology, Fisheries and Conservation Status. Washington, DC: International Bank for Reconstruction and Development and the World Bank.
Lucas, M. C., and E. Baras. 2001. Migration of Freshwater Fishes. London: Blackwell Science.
These data were derived by The Nature Conservancy, and were displayed in a map published in The Atlas of Global Conservation (Hoekstra et al., University of California Press, 2010). More information at http://nature.org/atlas.
