Surges in trematode prevalence linked to centennial-scale flooding events in the Adriatic

Abstract The forecasts of increasing global temperature and sea level rise have led to concern about the response of parasites to anthropogenic climate change. Whereas ecological studies of parasite response to environmental shifts are necessarily limited to short time scales, the fossil record can...
