This bibliography is intended to provide a review of the scientific literature from 2006 to the present. The starting point for compiling this review was an EndNote library provided by Sonja Kromann of the National Marine Mammal Laboratory. The listed sources are organized alphabetically by the lead author’s last name. “Northern fur seals are members of the ‘eared seal’ family (Otariidae). Northern fur seals, like all marine mammals, are protected under the Marine Mammal Protection Act. The Pribilof Islands/eastern Pacific stock is listed as depleted under the MMPA. In 1988, the Pribilof Islands population was designated as a depleted stock under the MMPA because it had declined by more than 50 percent from its estimated population of 2.1 million seals in the 1950s. Trends in abundance since the designation of the eastern Pacific stock are different for individual islands and even breeding areas.” - NMFS Sources Reviewed The following databases were used to identify sources: Science Direct, Clarivate Analytics’ Web of Science: Science Citation Index Expanded and Social Science Index; EBSCO Academic Search Complete and Environment Complete; ProQuest Aquatic Sciences and Fisheries Abstracts; NOAA Institutional Repository; BioDiversity Heritage Library; BioOne Complete; and JSTOR. 3 References Aalderink, M.

Journal of Comparative Pathology, 152(4), 325-334. https://doi.org/10.1016/j.jcpa.2015.02.002 Skulls from 145 northern fur seals (Callorhinus ursinus) were examined macroscopically according to predefined criteria. The museum specimens were acquired from strandings along the west coast of the USA between 1896 and 2008. Seventy-one skulls (49.0%) were from male animals, 56 (38.6%) from female animals and 18 (12.4%) from animals of unknown sex. Their age varied from juvenile to adult, with 58 adult animals (40.0%) and 87 juvenile animals (60.0%). The majority of teeth were available for examination (95.1%); 3.4% of teeth were artefactually absent, 0.8% were deemed absent due to acquired tooth loss and 0.6% were deemed congenitally absent. Males were no more likely than females to have either acquired tooth loss (P = 0.054) or congenitally absent teeth (P = 0.919). Adults had significantly more acquired tooth loss than juveniles (P = 0.0099). Malformations were seen in 11 teeth (0.2% of all 4,699 teeth available for examination). Two roots, instead of the typical one root, were found on 14 teeth (0.3%). Supernumerary teeth were associated with 14 normal teeth (0.3%) in eight specimens (5.5% of the total number of specimens). A total of 22 persistent deciduous teeth were found, 19 of which were associated with the maxillary canine teeth. Attrition/abrasion was seen on 194 teeth (3.9%); the canine teeth were most often affected, accounting for 39.7% of all abraded teeth. Adults were found to have a greater prevalence of abraded teeth than juveniles (P < 0.0001). No significant difference was found in the appearance of attrition/abrasion between males and females (P = 0.072). Tooth fractures were found in 24 specimens (16.6%), affecting a total of 54 teeth (1.1%). Periapical lesions were found in two skulls (1.4%). None of the specimens showed signs of enamel hypoplasia. About a fifth (18.6%) of alveoli, either with or without teeth, showed signs of alveolar bony changes consistent with periodontitis. A total of 108 specimens (74.5%) had at least one tooth associated with mild periodontitis. Lesions consistent with temporomandibular joint osteoarthritis (TMJ- OA) were found in 29 specimens (20.0%). Both periodontal disease and TMJ-OA were significantly more common in adults than in juveniles (P < 0.0001). Periodontitis was found to be more common in males than in females (P < 0.012). Although the significance of the high incidence of periodontitis and TMJ-OA in the northern fur seal remains unknown, the occurrence and severity of these diseases found in this study may play an important role in this species morbidity and mortality.

Studying individual activity patterns of seals at sea (i.e., estimating movements, calculating dive depth, identifying feeding locations, etc.) has relied mainly on telemetry and tagging; both methodolo- gies have been applied successfully for a wide range of geographical locations and species (e.g., Grey seals [Halichoerus grypus], McConnell et al., 1999; Hooded seals [Cystophora cristata], Hammill, 1993; 4 Northern fur seals [Callorhinus ursinus], Ream et al., 2005; South African fur seals [Arctocephalus pusillus pusillus], Oosthuizen, en, 1991; Southern elephant seals [Mirounga leonina], McConnell et al., 2002; Bester, 2006) and also included endangered species such as the Hawaiian monk seal (Monachus schauinslandi; Henderson & Johanos, 1988; Parrish et al., 2002).

The study's aim is to determine the feasibility of transrectal ultrasonography for assessing the reproductive status of female northern fur seals in the wild and to provide preliminary description of the reproductive tract and early embryo in situ. Subjects used were female northern fur seals of adult size, where ultrasonography was performed by an experienced operator with the use of a portable ultrasound unit. An overview of the results of the study is offered. Allen, B. M., & Angliss, R. P. (2012). Alaska Marine Mammal Stock Assessments, 2011.

Interactions between marine mammals and commercial fisheries are addressed under three new sections. This new regime replaced the interim exemption that has regulated fisheries-related incidental takes since 1988. Section 117, Stock Assessments, required the establishment of three regional scientific review groups to advise and report on the status of marine mammal stocks within Alaska waters, along the Pacific Coast (including Hawaii), and the Atlantic Coast (including the Gulf of Mexico). This report provides information on the marine mammal stocks of Alaska under the jurisdiction of the National Marine Fisheries Service. Each stock assessment includes, when available, a description of the stock’s geographic range, a minimum population estimate, current population trends, current and maximum net productivity rates, optimum sustainable population levels and allowable removal levels, and estimates of annual human-caused mortality and serious injury through interactions with commercial fisheries and subsistence hunters. These data will be used to evaluate the progress of each fishery towards achieving the MMPA’s goal of zero fishery-related mortality and serious injury of marine mammals. Allen, B. M., & Angliss, R.
