  4. Long-term observations from Antarctica demonstrate that mismatched scales of fisheries management and predator–prey interaction lead to erroneous conclusions about precaution

    that can help conserve marine predators. Uncertainty about the impacts of fisheries removals on ... dependent predators bolsters this perspective, but consideration of the spatio-temporal scales over which ... forage species, their predators, and fisheries interact can aid assessment of whether low catch limits ... hierarchical model and 30+ years of monitoring data, we show that expected penguin performance was reduced when ...
