MMI Associate Director Scott Baker is co-author on a study that describes new subspecies of short-finned pilot whale using genomic and mitogenomic data collected from individuals throughout the global range of the species. The results support the hypothesis that food-poor regions of the central Pacific Ocean have isolated these populations, leading to evolutionary divergence, despite the absence of physical barriers. The proposal to recognize the subspecies is important new information for managers and conservationists.

Blue whales reach their massive size by relying on their exceptional memories to find historically productive feeding sites rather than responding in real time to emerging prey patches, a new study concludes.

MMI graduate Dr. Alana Alexander has been awarded a Rutherford Foundation postdoctoral fellowship for research entitled, “Hologenomics for conservation: a first test of utility.” Congratulations, Alana!

Oregon Public Broadcasting filmed Dr. Leigh Torres in action, as she researches underwater sound and whale health.

Scientists at Oregon State University’s Marine Mammal Institute have pioneered new ways of documenting these incredible whale defecation events with aerial drones. Leigh Torres, an OSU MMI marine ecologist, is a specialist in this field who has helped capture illuminating views of gray whales for several years.

The population data created with Wildbook’s help can be used for much more than a census. At Oregon State University’s Marine Mammal Institute, professor Scott Baker uses the software to understand humpback whale migrations in the North Pacific. “It’s what we might call an informatics revolution,” said Baker. 

[VIDEO] While many Alaskans may not think of sharks having the same presence here as in other areas of the country or world, scientists are learning a lot from the species found off of Alaska's coasts. "Really we have no idea how many are out there and where they really hang out and what they do," Markus Horning, Science Director at the Alaska SeaLife Center said about his research on sleeper sharks. Earlier this summer, Horning and his team spent five days on the water in Resurrection Bay hoping to catch a sleeper shark.

Springtime is pup season. At this time of year, harbor seal pups are frequently found alone on area beaches. They are usually not stranded, but simply resting (as all baby mammals must do) and waiting for their mothers to come back ashore to nurse them. Adult female seals are shy and unlikely to rejoin a pup if there is activity nearby. They may only return to suckle their pup at night when people (and dogs) are not around. It is very important not to interfere with this process, and especially not to move a pup from where it is receiving care from its mother.

Within three or four weeks of birth, harbor seal pups are weaned from maternal care and are left to fend for...
