New FishME project publication: fish introductions and amphibian antipredator behaviour

Researchers from the FishME project investigated whether the presence of introduced fish affects background risk and antipredator sensitivity in larvae of the common frog (Rana temporaria).

Study results suggest that the presence of introduced fish may modify sensitivity to predation risk in amphibian larvae. Findings further highlight that biological invasions can influence not only direct predation risk but also prey behavioral responses and non-consumptive effects, with potential consequences at both population and landscape scales.
