Abstract We report the migration of ManayunkiaWe report the migration of Manayunkia 10 speciosa from its distribution in North America into the 11 Neotropical Region (Argentina). We collected speci- 12 mens from November 2007 to March 2009 in the lower 13 Uruguay River-at 33 5.010S 58 120W, 33 5.90S 14 5825.20W from sediments reaching densities of 2,890 15 ind. m-2, at a mean abundance of 350 ind. m-2. 16 Introductions of nonindigenous species, resulting inten- 17 tionally or accidentally from anthropic activities, cause 18 significant changes in ecosystems. In aquatic environ- 19 ments, polychaetes are a key invasive group that 20 increases the geographical range of several species 21 through human activities.M. speciosa may have reached 22 the Rý´o de la Plata Basin through a shipping vector and 23 thereafter the Uruguay River by self-navigation 22 the Rý´o de la Plata Basin through a shipping vector and 23 thereafter the Uruguay River by self-navigation 16 Introductions of nonindigenous species, resulting inten- 17 tionally or accidentally from anthropic activities, cause 18 significant changes in ecosystems.
