Climate change and biological invasion as additional threats to an imperiled palm

Climate change and biological invasion are major threats to biodiversity, but their combined effects haverarely been quantified. The introduction of congeneric non-native species, in particular, can be especially problematic for native species due to competition and hybridization. Here, we quantify the impacts ofclimate change on the distribution of an ecologically and economically important native species, Euterpeedulis, and on the invasion potential of its congeneric E. oleracea, across the Atlantic Forest biodiversity hotspot.
