*Abstract: *Distinct populations may respond differently to range‐wide
exploitation, resulting in evolutionary impacts and reduced genetic
diversity that can limit recovery and resilience of remnant populations.
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.
