When aposematism is not enough: Exotic Rattus rattus shows no mercy for carcasses of Salamandra salamandra in insular populations vs. Salamandra salamandra - videos ...
Predator-prey interaction is a major force driving natural selection. Yet, the effect of possible predators on aposematic species is largely unknown. Islands constitute excellent natural laboratories to investigate predator-prey coevolution due to their isolation and relatively simple biological com...
