genetic study uncovers secrets of beluga whale mating systems
In January, 2026, we published the first detailed genetic study on beluga whale mating systems in Frontiers in Marine Science. This was a big lift, spanning 13 years, hundreds of samples, and long hours in the lab and at the computer. But it was worth it. Beluga whales, at least in Bristol Bay, Alaska where the research was conducted, have what is called a polygynandrous mating system where both males and females have multiple partners over a long reproductive life. Such a system may be key to lowering inbreeding and maintaining genetic diversity, even in small populations.
The project was a joint effort between FAU-Harbor Branch, the Alaska Department of Fish and Game, the Bristol Bay Native Association Marine Mammal Council and the Alaska Beluga Whale Committee and showcases what can be achieved through community-based science Quyana to all!

movement data from two satellite tagged beluga whales during summer 2025:
In July, 2025, we assisted the Native Village of Point Lay, Alaska and the North Slope Borough Department of Wildlife Management on a satellite tagging project on beluga whales. Two beluga tags from the July deployment are still active. Their movement from 01 Nov – 01 Dec 2025 are included in the attached map. Sea ice data were from 01 Dec 2025. Tagging was conducted under NMFS Permit No. 24334 issued to the Alaska Department of Fish & Game. Thanks to Caroline Wilford at NSBDWM for the maps.
