In this study, we use molecular genetic data to test a priori hypotheses about population subdivisions generated from a decade of killer whale surveys across the northern North Pacific. A total of 462 skin biopsies were collected from free-swimming killer whales from 1990 to 2010 between the northern Gulf of Alaska in the east and the Sea of Okhotsk in the west, representing both the piscivorous resident and the mammal-eating Biggs (or transient) killer whales. Geographic patterns of genetic differentiation were supported by significant regions of genetic discontinuity providing evidence of population structuring within both lineages, and corroborating direct observations of restricted movements of individual whales. In the Aleutian Islands (Alaska), population strata were largely delimited by major oceanographic boundaries for resident killer whales. In contrast, subdivisions among Biggs killer whales indicated multiple genetic clusters in the Eastern Aleutians and Bering Sea. The presence of sympatric genetic clusters within Biggs whales suggests the presence of isolating mechanisms other than geographic distance within this highly mobile top predator. These data were collected to assess and quantify the population genetic structure of killer whales in the northern North Pacific between the Gulf of Alaska and the Russian Far East. Contributions to the dataset were also made by: Southwest Fisheries Science Center; North Gulf Oceanic Society; Far East Russia Orca project. underDevelopment Clapham, Phillip phillip.clapham@noaa.gov pointOfContact Parsons, Kim kim.parsons@noaa.gov custodian asNeeded biopsy locations ecotype genetics haplotype mtDNA control region population genetic strata theme Aleutian Islands Bering Sea Gulf of Alaska northern North Pacific place DOC/NOAA/NMFS/AFSC > Alaska Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
