Marine Mammal Genetics Group


Gray whaleThe Marine Mammal Genetics Group identifies population structure using primarily genetic data. Population structure is identified at two levels: the evolutionary level, which is integral to implementing the Endangered Species Act, and the demographic level, which forms the basis for conservation under the Marine Mammal Protection Act. Effective conservation and management efforts of marine mammals rely on accurate identification of population structure at both of these levels.

We integrate our strong expertise in conservation biology, systematics and population genetics to provide the best information possible to identify population structure. We collaborate closely with the expertise in other research divisions including population dynamics, ecology, behavior, life history, acoustics, oceanography and photogrammetry.

Research is supported by our state-of-the-art conservation genetics laboratory and genetics tissue archive. The latter houses a continually growing world-wide sample collection enriched by international scientific collaborations. The genetics archive, the genetics laboratory, and the database operated by our group provide the infrastructure necessary to drive the management science and ensure high quality data for current and future needs. We also develop new molecular techniques and innovative analytical approaches designed specifically to improve management decisions and provide expert advice on population structure at regional, national and international management and academic meetings.
