How does the climate crisis affect the Antarctic fur seal?

The climate crisis is limiting the availability of krill — small crustaceans that are vital in the marine food chain — during summer in some areas of the Antarctica. This involves a decrease in the food abundance for female Antarctic fur seals in summer and a decrease in their reproductive success. Moreover, the predation of pups by the leopard seal has also increased due to a lower abundance of penguins, the main prey of this voracious Antarctic predator. However, the impact of the climate crisis on the Antarctic fur seal in winter has been ignored to date, when the cold, wind and ice make it harder to study the Antarctic ecosystems.
