Study Notes
- Scientists are interested in the diets of marine predators due to climate change.
- Orcas are the largest predators in the ocean, but their dietary habits are not fully understood.
- A new technique has been developed to reconstruct the precise diet of orcas using skin and blubber samples.
- Orcas use various hunting techniques, including creating waves to dislodge seals and feeding on herring in a carousel formation.
- Different orca populations have unique diets and lifestyles, such as the transient and resident orcas in the Northeast Pacific.
- Orcas have been observed to cause trophic cascades, affecting the entire food chain.
- It is difficult to observe the diets of orcas in remote regions like the Arctic.
- Initial studies suggested two types of orcas in the North Atlantic, but further research has shown more dietary diversity.
- Researchers analyze chemical tracers in orca skin and blubber to understand their diet and impact on the food chain.
- This technique can provide valuable insights into the ecological role of orcas in different regions.
