In this episode of the How to Protect the Ocean podcast, host Andrew Luan discusses the significant decline in the population of common murres, a seabird species in Alaska, which has seen about half of its population die off—approximately 4 million individuals—since the marine heat wave known as "the blob" occurred from 2014 to 2016.

The primary reason for this drastic decline is linked to the effects of the heat wave on the marine food web rather than direct thermal stress on the birds themselves. The heat wave caused shifts in the availability of food sources, leading to starvation among the murres. The study highlighted that the murres rely heavily on oceanic food supplies, and disruptions in these supplies can have devastating impacts on their populations.

Research conducted by the University of Washington and the U.S. Fisheries and Wildlife Service revealed that the murre population in the Gulf of Alaska dropped by half, while in the eastern Bering Sea, the decline was even steeper at 75%. The study emphasized that without a recovery in the prey populations, the murres are unlikely to rebound, indicating a potential tipping point in the ecosystem that could prevent recovery for this species and others reliant on the same food sources.

Overall, the episode underscores the importance of understanding and funding research on marine ecosystems to address the long-term impacts of climate change and marine heat waves on wildlife populations.

In this episode of the How to Protect the Ocean podcast, host Andrew Lewin discusses the fascinating behavior of orcas, particularly their recent predation on whale sharks, the largest fish in the ocean.

Orcas, known as apex predators, have been observed hunting whale sharks in the Gulf of California. This behavior was documented in a new study published in the journal Frontiers of Marine Science, which includes video footage and images of the attacks. The orcas target the whale sharks by striking their underbelly and grabbing their pectoral fins, aiming for the nutrient-rich liver, similar to their hunting strategies for great white sharks.

The study tracked four predation events over six years, highlighting a male orca named Moctezuma, who participated in three of these events alongside females from the same pod. This suggests that the orcas are learning and refining their hunting techniques over time.

Lewin emphasizes the importance of understanding this new predation behavior, as it indicates that whale sharks have a formidable predator. He also stresses the need for conservation efforts to protect whale sharks, which face threats from climate change, pollution, and fishing activities. The episode concludes with a call for further research and discussion on the implications of orcas hunting whale sharks and the overall health of marine ecosystems.
