Mange has decimated the population of wild vicuñas and guanacos in an Argentinian national park that was created to conserve them, according to a study from the Administration of National Parks in Argentina and the University of California, Davis.
The findings, published today in the journal PLOS ONE, suggest domestic llamas introduced to the site may have been the source of the outbreak. Cascading consequences for local predator and scavenger species are expected.
