SPEAKER SERIES 2013-2014
The Puget Sound Chapter of the American Cetacean Society's Speaker Series, a free fun educational activity, occurs once a month from September through June; with a break in December for the winter weather and holidays.
18 September 2013 - Jennifer Hempelmann, NWFSC
Paternity and Male Reproductive Success in the Southern Resident Killer Whale Population (SRKW)
Jennifer will give an overview of the breeding structure of the SRKW population, including an update of the family tree with the latest paternity assignments and parentage results of deceased neonate calves.
Jennifer Hempelmann is a molecular geneticist working at NOAA's Northwest Fisheries Science Center in Seattle. Her scientific background includes a degree in Zoology from the University of Washington and genetic research on rockfish populations. Since 2005, she has worked with marine mammal scientists to study the diet and population structure of the endangered Southern Resident killer whales by analyzing DNA found in whale scat and skin samples.

The Harbor Porpoise in Puget Sound
In the 1940s and 50s, the harbor porpoise (Phocoena phocoena) was an
abundant cetacean in the Salish Sea. By the 1990s, its numbers and range had
shrunk to the point that it was rarely seen south of Admiralty Inlet. At
the present time, a number of anecdotal sightings may indicate that the
species is recovering, but very little is known about its population trends.
While there is no federal listing for the harbor porpoise, the Washington
Department of Fish and Wildlife has designated the harbor porpoise a State
Candidate Species. Canada has designated the harbor porpoise a Species of
Special Concern, recognizing that it is particularly vulnerable to human
activities. Aileen Jeffries, a Pacific Biodiversity Institute (PBI) board
member, initiated a project to monitor the harbor porpoise population and
trends in the Salish Sea in 2008. The long-term goal of this project is to
set a baseline for the population that can be used to realistically assess
the stability of the species. Another goal of the project is to investigate
if the harbor porpoise is a sentinel species in the Salish Sea. Aileen has
been using land-based observations and acoustic monitors to try to
understand this cryptic species. She will present data from her studies and
discuss what she is learning. Her research project is testing and
calibrating acoustic monitors as a new tool for population assessment for
the harbor porpoise.
Aileen Jeffries retired from a long career as a research physicist and has
enjoyed transferring her skills to acoustics for studying the harbor
porpoise. Pacific Biodiversity Institute is a non-profit organization
dedicated to using the best available science to enhance natural resource
planning and management decisions.

New insights into Bigg's (transient-type) killer whales from the western Aleutian Islands -- a squid-eating separate species of killer whale?
Recent studies using whole mitochondrial genomes indicate transient-type killer whales in the North Pacific have been separated from other killer whales for hundreds of thousands of years, and may represent a separate species, to go along with the multiple species identified in the Antarctic. In addition, our studies in the Aleutian Islands have identified significant population structure within Bigg's killer whales, and field observations, satellite tagging and stable isotope studies suggest whales in the western Aleutians may eat a substantial amount of squid in addition to marine mammals.
Dr. Wade is a research fisheries biologist in the Cetacean Program (http://www.afsc.noaa.gov/nmml/cetacean/) at the National Marine Mammal Laboratory, Alaska Fisheries Science Center, NOAA Fisheries, in Seattle, Washington. He is also an Affiliate Professor at the School of Fisheries and Aquatic Sciences at the University of Washington. He has conducted population and ecological research on gray, bowhead, right, humpback and false killer whales, and on spotted, spinner, striped, and common dolphins.
Since 2001 his field research has focused on killer whales in the Aleutian Islands and Bering Sea. He is a member of the U.S. delegation to the Scientific Committee of the International Whaling Commission, the Cetacean Specialist Group of the IUCN Species Survival Commission, and the Steering Committee of the SPLASH North Pacific humpback whale project (http://hawaiihumpbackwhale.noaa.gov/science/splashinfo.html). He has published over 70 peer-reviewed papers, and over 50 additional non peer-reviewed scientific documents.

Hawai i's resident and not-so-resident Blackfish: recent studies of false killer whales and killer whales in Hawai i
There are two top predators in the marine environment in Hawaii, both of which are very rare, the false killer whale, which cooperatively hunts for large pelagic fish like tuna and swordfish, and the killer whale, which feeds on sharks, dolphins, squid, and other whales. One of these is resident to the islands, one only passes through the area, and one of them was listed as Endangered in 2012, the most recent species of whale listed under the Endangered Species Act. This presentation will summarize what is known about both species in Hawaiian waters including recent results from tagging and photo-identification.
Robin Baird is a research biologist with Cascadia Research Collective, based in Olympia. Although still dabbling with work on killer whales in the Pacific Northwest, most of his research for the last 14 years has been focused on toothed whales and dolphins in Hawaiian waters. He is also a member of the Committee of Scientific Advisors of the U.S. Marine Mammal Commission, an adjunct faculty at Hawaii Pacific University and the University of Washington, and a member of the false killer whale Take Reduction Team.

Whales as a source of raw materials: A look at historic and recent whale products
The lure of hunting whales in the past can be explained when we consider the high value placed on the raw materials that could be extracted from them. While in earlier times the whales were stripped of blubber and whalebone (baleen), and the rest of the carcass discarded at sea, technological advances in the twentieth century made it possible to utilize the entire whale. From whalebone corsets to spermaceti candles, from military explosives to cattle feed, we'll take a closer look at the extensive and strange variety of whale products derived from these leviathans.
We will have a sizeable collection of historic and recent whale products on hand (which you may touch), each with their own interesting and disturbing story.
