How biological invasions are redrawing the geography of freshwater fish biodiversity

Freshwater fish assemblages reflect millions of years of geographic isolation, producing unusually strong regional endemism. This seminar traces how tectonic history shaped those regions and how human transport and local extinctions now disrupt them. It examines the social drivers and ecological consequences of introductions, the resulting reorganization of global fish distributions, and the lasting effects of changes imposed within only a few decades.
