Data from: Age and sex-selective predation as moderators of the overall impact of predation ...
Currently, there is no general agreement about the extent to which predators’ impact prey population dynamics, as it is often poorly predicted by predation rates and species abundances. This could in part be caused by variation in the type of selective predation occurring. Notably, if predation is s...
