Ecology of Fear: Current Implications of Orca Presence on Narwhal Behavior and Future Trends

The ecology of fear is a hypothesis that predators drive habitat use and behavior in prey species. In the Arctic, the orca drives behavioral changes in a variety of species including narwhals. Analyzing a narwhal population in a Fjord in Greenland researchers were able to look at how fear drives narwhal behavior. Article Breed, Greg […]

The Biological Big Bang: Testing the hypothesis that sperm whales use auditory bursts to stun prey and other proposed feeding strategies.
