In this episode, Max Friesen, Eline Lorenzen, and Mikkel Skovrind explore beluga population dynamics in relation to subsistence hunting by Indigenous communities in northern Canada.
In this episode, we cover:
•[00:00] Introduction
•[01:01] Archaeologist Max Friesen talks about the role of belugas in Inuvialuit culture.
•[01:45] Evolutionary biologist Eline Lorenzen talks about the background of the study.
