FAILLA, Mauricio  and  FASOLA, Laura. American mink: a new invader of Rio Negro, Argentine Patagonia. Mastozool. neotrop. [online]. 2019, vol.26, n.2, pp.482-486.  Epub Aug 04, 2019. ISSN 0327-9383.

American mink (Neovison vison) is the most widespread invasive carnivore in Patagonia. Based on field surveys and historical records, we present novel and detailed information of the American Mink present distribution along 180km of the Río Negro. This invasion nucleus represents the most northeastern area recorded for the species, a new invaded ecoregion (Monte Oriental) and a new province with wild populations (Buenos Aires). We document the existence of a fur farm located in Carmen de Patagones and Viedma cities (1965-1974) that may have originated this focus. We recommend the prompt design and implementation of a control plan.
