Sequencing the full mitogenomes and 37 novel microsatellites for 127 specimens of northern bottlenose whales(Hyperoodon ampullatus), we reconstructed the trajectories of two distinct populations that were heavily exploited by commercial whaling. We found that for a small population at their range edge, the impacts of whaling were more severe than for the larger more connected population, and combined with having the lowest range‐wide genetic variability of any cetacean, we suggest northern bottlenose whales may face genetic limitations to the recovery of their populations. *About the Speakers: * *Laura Joan Feyrer* is the Chief Scientist for the Northern Bottlenose project and a PhD candidate, working with Dr. Hal Whitehead at Dalhousie University. Most of her field work has been conducted from a 40’ sailboat 200 miles offshore of Nova Scotia in the Sable Gully, and around the Grand Banks of Newfoundland. Her research focuses on the population ecology and management of endangered northern bottlenose whales in the Northwest Atlantic. * Dr. Anthony Einfeldt* is a researcher working on conservation genomics and population genetics in marine systems,particularly in the North Atlantic. He uses genetic tools to address ecological and evolutionary questions, such as how humans shape species' distributions,how dispersal abilities and the environment interact to connect populations,and how sex chromosomes evolve. These questions involve work on a diverse array of systems, including mudflat invertebrates, marine and anadromous fishes, and beaked whales. *Subscribe to the OneNOAA Science Seminar weekly email: *Send an email to OneNOAAscienceseminars-request@list.woc.noaa.gov with the word `subscribe' in the subject or body.
