Summary of northern fur seal data and collection procedures. Imprint. Seattle, Wash.: National Marine Mammal Laboratory, Northwest and Alaska Fisheries Center, National Marine Fisheries Service, National Oceanic and Atmospheric Administration ; Springfield, Va.: National Technical Information Service [distributor], Physical description.

This book reports on a year study of the northern fur seal, Callorhinus ursinus (Linnaeus ), a medium-sized eared seal (Pinnipedia, family Otariidae) that inhabits the Pacific Ocean from about 35 to 60 north latitude.

The study was designed to answer specific behavioral questions about a long-term decline in fur seal : Population data, collection procedures and management of the northern fur seal, Callorhinus ursinus, of the Pribilof Islands, Alaska (OCoLC) Material Type: Document, Government publication, National government publication, Internet resource: Document Type: Internet Resource, Computer File: All Authors / Contributors.

The northern fur seal (Callorhinus ursinus, Linnaeus ) is a sexually dimorphic species. Mature males exceed the size of females by an average factor ofand are black to reddish brown in colour. Females are gray-brown along their dorsal.

This online bibliography is based on a publication which lists northern fur seal (Callorhinus ursinus) literature available up to that time. Additional northern fur seal citations, literature, and related archival information are available in the Marine Mammal Library's Northern Fur Seal Archive and the AFSC Publications Database.

Northern fur seals breeding on the Pribilof Islands are characterized by pelagic migrations that begin each fall and last approximately eight months.

Previous studies have examined the Summary of northern fur seal data and collection procedures book phases of the migration with respect to timing, location, and effects of ocean surface currents on movement. We used satellite telemetry and remotely sensed satellite data to examine relationships.

Google Scholar. Northern fur seals have a stocky body, small head, very short snout, and extremely dense fur (46, fibers/cm²) that ends at the wrist lines of their flippers. Their flippers are the longest in the Otariidae family. Their hind flippers can measure up to one-fourth of their total body length.

Northern fur seals (Callorhinus ursinus, previously referred to as the Alaska fur seal) are found in the North Pacific and Bering Sea. The largest portion of the worldwide population returns to the Pribilof Islands, Alaska, in the eastern Bering Sea during their annual breeding season.

To facilitate population analyses, the following data and explanations of collection procedures on land since the Convention are summarized for the northern fur seal, Callorhinus ursinus, of the Pribilof Islands, Alaska: rookery-specific counts and estimates of numbers of pups born, live pups, and dead pups (); information on causes of pup mortality on land (); rookery.

Description: This is the first of several reports being produced as a result of the Seattle Data Workshop which the Standing Scientific Committee convened in December In a form suitable for detailed population studies, the Commission assembles here in one document much of the data collected from the exploited fur seal stocks on the Pribilof Islands, Commander Islands, and Robben Island since the.

e subject of this manual, the northern fur seal, i~ one of the more ctable otariids. The equipment and techniques described here were developed dur­ g the past 8 yr. Some of the methods have been used successfully on e Afro-Australian fur seal, Arctocephalus pusillus pusillus, and the ntarctic fur seal.

The northern fur seal was first described by Georg Wilhelm Steller inand the largest part of the population was found on the Pribilof Islands by Gerassim Pribilof in The number of fur seals reached its lowest level, aboutin after per­.

Summary description of the data: This data set is comprised of satellite-linked telemetry data collected to investigate winter migration patterns and foraging strategies of adult male northern fur seals as published by Sterling et al.

This chapter tells the story of how the northern fur seal (Callorhinus ursinus) was nearly hunted to extinction, and how the North Pacific Fur Seal Treaty of not only reversed this situation, but probably sustained the efficient harvest of this resource.

The case study illustrates that treaties can change behavior, but only by strategically manipulating the incentives that countries face. Northern Fur Seal Image Archive. The Related Groups category refers to groups of ground-level images that are of the similar locations, though they may have been taken at different times.

The images within a Related Group can be used to compile a photo time series, showing the changes of a specific location over time.

Reconstructing Northern Fur Seal Population Diversity through Ancient and Modern DNA Data by Cara Leanne HalsethUniversity of Northern British Columbia,   Skulls from northern fur seals (Callorhinus ursinus) were examined macroscopically according to predefined museum specimens were acquired from strandings along the west coast of the USA between and Seventy-one skulls (%) were from male animals, 56 (%) from female animals and 18 (%) from animals of unknown sex.

Data Management Plan for Catalog Item ID: These data sets were used by Zeppelin et al. () to model northern fur seal foraging habitats based on stable isotope values measured in plasma and red blood cells, and satellite-linked tag measures of locations and diving behavior.

The Linked Data Service provides access to commonly found standards and vocabularies promulgated by the Library of Congress.

This includes data values and the controlled vocabularies that house them. Datasets available include LCSH, BIBFRAME, LC Name Authorities, LC Classification, MARC codes, PREMIS vocabularies, ISO language codes, and more.

Thus, this is the first ecological study on tapeworms from the northern fur seal based on a large amount of a freshly collected material confirmed by morphological and molecular data (see Hernández-Orts et al., ). Moreover, these data were obtained during a large scale study over four consecutive seasons and with a high number of NFSs.

During the summer breeding season, most of the worldwide population is found on the Pribilof Islands in the southern Bering Sea, with the remaining animals on rookeries in Russia, on Bogoslof Island in the southern.

Females and juveniles from the Pribilof Islands migrate to offshore waters from Canada down to California, and to the west as far south as Japan. Northern fur seals, data collection, and sample analysis.

Prior todiet studies on northern fur seals were based primarily on prey remains in stomachs and GI tracts of animals shot at sea, and since that time on prey remains from scats collected on rookery island sites.

The northern fur seal (Callorhinus ursinus) is an eared seal found along the north Pacific Ocean, the Bering Sea, and the Sea of is the largest member of the fur seal subfamily (Arctocephalinae) and the only living species in the genus Callorhinus.A single fossil species, Callorhinus gilmorei, is known from the Pliocene of Japan and western North America.

Northern fur seals were killed for their skins for at least years on the Pribilof Islands (Scheffer et al.,and NMFS ). Northern fur seal population trends are most closely related to the number of females because a single territorial adult male inseminates multiple reproductive females.

According to IUCN, as ofthe Northern fur seal population have been estimated at 1 - million, the majority breeding on the Pribilof Islands located in the southern Bering Sea.
