    Andrew A. Schaffner; Stephen B. Mathewsf Judith E. Zeh* April 21, 1994 Abstract From June 1985 through June 1992 regular aerial surveys over Southeast Alaska, the Gulf of Alaska, and Aleutian Islands were conducted to monitor the distribution and abundance of Steller sea lions (Eumetopias jubatus). Furthermore, during 1992 the use of repetitive aerial surveys was introduced to study survey variability. The purposes of our present study were two-fold: (1) To investigate alternative statistical procedures for estimating population trend rates from aerial survey counts, and (2) to apply these procedures to the 1989-92 counts. We focused on 1989-92 because of the more abundant data for that period and to determine the most recent direction of population abundance relative to the well-documented steep decline prior to 1989. We concluded that parametric bootstrapping was the most appropriate interval estimation procedure. For this procedure the 90% confidence interval for the rate of change between the 1989 and 1992 Kenai-Kiska Recovery Plan trend site counts was (-10.19%, 2.62%). For +lJrookery and haul-out sites within the Kenai-Kiska region for which counts were made for both 1989 and 1992, the 90% confidence interval was (-6.20%, 6.81%). For sites outside the Kenai-Kiska region, the 90% confidence interval for the rate of change between 1989 and 1992 was (-37.92%, -6.93%). The parametric bootstrap procedure had the weakness of including data from only pairs of years; thus, 1990-91 information was excluded from the above interval estimates. Consequently, we investigated the use of both generalized linear modeling (GLM) and generalized estimating equations (GEE) as tools for analyzing all four years' data together.

Schneider Project Title: Marine Mammal Investigations Project Nos.: W-17-4 thru W-17-8 Job No. : Job Title: Sex and Age Segregation of Sea Otters Period Covered: July 1, 1971 to June 30, 1976 SUMMARY Knowledge of patterns of geographical segregation of sea otters by sex and age is essential to any active conservation and management program on that species. The sexes and ages of sea otters harvested or captured from several Alaskan populations were examined by specific location and season to determine patterns of segregation. All populations contained large female areas where most adult females and dependent pups in the population were found. The number of sexually mature males over 5 years old in female areas fluctuated seasonally and was positively correlated with the number of estrous females. Sexually immature males between the ages of 1 and 6 years appeared to be actively excluded from female areas. Where high densities of sea otters were continuous and range expansion had ceased, many adult males and most immature males concentrated in geographically discrete male areas. Permanently established male areas did not exist in some populations where areas of high sea otter density were separated by areas of low density or where the population was expanding into vacant habitats.

  • Geopolitics and Environment in the Sea Otter Trade
    UC Merced UC Merced Electronic Theses and Dissertations Title Soft gold and the Pacific frontier: geopolitics and environment in the sea otter trade Permalink https://escholarship.org/uc/item/03g4f31t Author Ravalli, Richard John Publication Date 2009 Peer reviewed|Thesis/dissertation eScholarship.org Powered by the California Digital Library University of California 1 Introduction Covering over one-third of the earth‘s surface, the Pacific Basin is one of the richest natural settings known to man. As the globe‘s largest and deepest body of water, it stretches roughly ten thousand miles north to south from the Bering Straight to the Antarctic Circle. Much of its continental rim from Asia to the Americas is marked by coastal mountains and active volcanoes. The Pacific Basin is home to over twenty-five thousand islands, various oceanic temperatures, and a rich assortment of plants and animals. Its human environment over time has produced an influential civilizations stretching from Southeast Asia to the Pre-Columbian Americas.1 An international agreement currently divides the Pacific at the Diomede Islands in the Bering Strait between Russia to the west and the United States to the east. This territorial demarcation symbolizes a broad array of contests and resolutions that have marked the region‘s modern history. Scholars of Pacific history often emphasize the lure of natural bounty for many of the first non-natives who ventured to Pacific waters. In particular, hunting and trading for fur bearing mammals receives a significant amount of attention, perhaps no species receiving more than the sea otter—originally distributed along the coast from northern Japan, the Kuril Islands and the Kamchatka peninsula, east toward the Aleutian Islands and the Alaskan coastline, and south to Baja California.

  • A Historical Perspective on the Citrus-Like Scent of the Crested Auklet Spencer G
    A HISTORICAL PERSPECTIVE ON THE CITRUS-LIKE SCENT OF THE CRESTED AUKLET SPENCER G. SEALY, Department of Zoology, University of Manitoba, Winnipeg, Manitoba R3T 2N2, Canada; [email protected] ABSTRACT: The tangerine-like odor produced by breeding Crested Auklets (Aethia cristatella) of both sexes has attracted considerable attention recently as re- searchers attempt to determine its function. Chicks and one-year-old immatures do not produce the odor. Even though the odor has long been known to the Yu’pik people of St. Lawrence Island, naturalists and ornithologists visiting seabird colonies on the Aleu- tian Islands and in the Bering Sea from the mid-1700s through first half of the 20th century did not mention the odor. I trace the steps of two early ornithologists, Charles H. Townsend and Ira N. Gabrielson, whose numerous visits to auklet colonies in the late 1800s and 1940s, respectively, provided opportunities to smell the scent. The odor was eventually described on the basis of specimens smelled during preparation and on the basis of encounters with the auklets at sea. The closely related Whiskered Auklet (A. pygmaea) also produces an odor, but its function requires study. The plumage of both males and females of the highly social Crested Auk- let (Aethia cristatella) exudes an odor like that of a tangerine. The odor is more intense during the breeding season (Douglas et al. 2001, Hagelin et al. 2003). During the stereotyped “ruff-sniff” courtship display (Figure 1), males and females rub their bills in turn in the feathers of the nape and neck of their displaying partners (Jones 1993, Jones and Hunter 1993, Hunter and Jones 1999).

    WESTEP BltlDS Volume 28, Number 2, 1997 INVENTORY OF THE SPECIES AND SUBSPECIES OF ALASKA BIRDS DANIEL D. GIBSON and BRINA KESSEL, Universityof Alaska Museum, Fairbanks, Alaska 99775-6960 The most recent inventory of all of the modern avian taxa known from Alaska has been for many years that of Gabrielsonand Lincoln(1959), who discussed311 speciesand an additional 102 subspecies.Their data and many of their assessmentswere also reflectedin the fifth edition of the AOU Check-list of North American Birds (1957), producedby a committeeof which E C. Lincolnwas a member.In the 41 yearsthat have elapsedsince 1956, when their data collection ended, many additional species and subspecieshave been recordedin Alaska, the validityand limits of numerous taxa have been re-evaluated, and new subspecieshave been described. Some of these new subspecieshave been describedfrom Alaska (Feinstein 1958, Kemsies1961, Webster1983, Rea and Websterin Phillips 1986, Gibsonand Kessel1989, Phillips 1991, Dickermanand Gustarson1996), from adjacent Canada (Browning 1994), or from northeastern Russia (Tomkovich 1986, 1990). Other subspeciesthat affect an assessmentof species here have been describedfrom distant localities (Phillips 1962, Burleigh 1963, Walkinshaw1965, White 1968, Oberholser1974, Delacour and Ripley 1975, Phillips 1981, Dickerman 1986, Jehl 1987a). Our own ongoing efforts to verify the identificationsand associateddata of Alaskavoucher specimens of particularhistorical or distributionalsignifi- cance led to this paper. Because Alaska is a vast, zoogeographically dynamic,and pivotallyimportant interfacebetween the Old World and New World avifaunas,we have compiledthis inventoryto providean up-to-date regional review of the continuing process of learning and proving the distributionsof wild birds--by collectingand careful subsequentmuseum studies(see Phillips 1986:xxxii).
