Long-term studies quantify the prey requirements of pinnipeds, and help predict the effects of nutritional stress.
Two new studies answer the question: “How much fish does a seal need?” One of the most common threats to marine mammal populations is reduced food supply, either due to the effects of climate change or human fishing pressure.
