The global invasion routes of the red swamp crayfish, described based on genetics

A study led by researchers at the Doñana Biological Station of the Spanish National Research Council (CSIC), in collaboration with institutions in Europe, America and Asia, has identified the main introduction routes of the red swamp crayfish, Procambarus clarkii, during its global-scale invasion. This North American species is the most widely spread freshwater crayfish worldwide, and is one of the worst invasive species due to its impact on the structure and functioning of freshwater ecosystems.
