Marine Mammal Institute

The OSU Marine Mammal Institute is a multi-disciplinary facility incorporating the work of academics from engineering, genetics, agriculture, aquatics, ecology, veterinary medicine, biology, and communications. As the only institute of its kind, the Marine Mammal Institute combines the efforts of top researchers from around the world to continue the legacy of discovery and preservation of critical habitats of target species and to understand how those species interact with their environment and human activities.

Humpback whales make a comeback in Australian waters as numbers rebound

MMI's Ari Friedlaender has co-authored a new paper describing how humpback whale populations have rebounded to up to 90% of pre-whaling numbers in Australian waters and should no longer be officially considered a threatened species.

Episode 21: Diving into the past -- Understanding the diving behaviour of tropical seals across time

Jana Jeglinski (University of Glasgow) and Markus Horning (Oregon State University) both studied the diving behaviour of Galapagos fur seals (Arctocephalus galapagoensis) during PhDs conducted twenty years apart. Recently, they met in Glasgow to compare their data sets and see what this might tell us about long-term changes in the equatorial ocean environment.

Longest mammal migration raises questions about distinct species

A team of scientists from the United States and Russia has documented the longest migration of a mammal ever recorded – a round-trip trek of nearly 14,000 miles by a whale identified as a critically endangered species that raises questions about its status. The researchers used satellite-monitored tags to track three western North Pacific gray whales from their primary feeding ground off Russia’s Sakhalin Island across the Pacific Ocean and down the West Coast of the United States to Baja, Mexico. One of the tagged whales, dubbed Varvara, visited the three major breeding areas for eastern gray whales, which are found off North America and are not endangered. Results of their study are being published this week by the Royal Society in the journal Biology Letters.
