Oryctolagus cuniculus Linneaus, 1758 (Mammalia: Lagomorpha: Leporidae): new record in the Nahuel Huapi National Park, Patagonia, Argentina

Biological invasions are difficult to control when invader's populations attain high densities; therefore early detection is important for implementing management strategies. This study presents the first record of the European rabbit, Oryctolagus cuniculus Linneaus, 1758, in Nahuel Huapi National Park, Patagonia, Argentina and confirms its dispersion in habitats adjacent to the Siete Lagos route. Considering the potential ecological consequences of rabbit in a protected area, the early detection of this invasive species will allow the National Park Administration to implement urgent control measures in order to stop the advance.
