Implantation of subcutaneous heart rate data loggers in southern elephant seals (Mirounga leonina) [PDF]

open access: yes, 2017
Unlike most phocid species (Phocidae), Mirounga leonina (southern elephant seals) experience a catastrophic moult where they not only replace their hair but also their epidermis when ashore for approximately 1 month.

Annotation and comparative analysis of T cell receptor germline genes reveal lineage-specific patterns in pinnipeds

open access: yesFrontiers in Immunology
Adaptive immunity in jawed vertebrates relies on V(D)J recombination, yet the expansion–contraction dynamics of germline genes remain underexplored, especially in secondary aquatic mammals.

The First Population Simulation for the Zalophus japonicus (Otariidae: Sea Lions) on Dokdo, Korea

open access: yesJournal of Marine Science and Engineering, 2022
The Japanese sea lion (Z. japonicus) has been regarded as an extinct species since the last report on Dokdo in 1951. Not much ecological information on the Z. japonicus on Dokdo (hereafter Dokdo sea lion) is currently available.

Selective Inner Hair Cell Loss in a Neonate Harbor Seal (Phoca vitulina)

open access: yesAnimals, 2022
Congenital hearing loss is recognized in humans and other terrestrial species. However, there is a lack of information on its prevalence or pathophysiology in pinnipeds.

A critical revision of the fossil record, stratigraphy and diversity of the Neogene seal genus Monotherium (Carnivora, Phocidae) [PDF]

open access: yes, 2018
Historically, Monotherium had been one of the few genera of extinct Phocidae (true seals) that served as a wastebin taxon. Consequently, it did neither aid in understanding phylogenetic relationships of extinct Phocidae, nor in understanding seal ...

Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

open access: yesThe Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.

Improvement in survivorship: The key for population recovery? [PDF]

open access: yes, 2016
In northern Patagonia, commercial harvesting of South American sea lions, Otaria flavescens, from 1920 to 1960, decimated its population abundance. Population recovery was not immediate after hunting ceased in 1962.

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

open access: yesThe Anatomical Record, EarlyView.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

Trends and Potential Interactions Between Pinnipeds and Fisheries of New England and the U.S. West Coast [PDF]

open access: yes, 2000
Long-term trends in the abundance and distribution of several pinniped species and commercially important fisheries of New England and the contiguous U.S. west coast are reviewed, and their actual and potential interactions discussed.

Dolphin Morbillivirus in Eurasian Otters, Italy [PDF]

open access: yes, 2019
We report biomolecular evidence of dolphin morbillivirus in 4 wild Eurasian otters (Lutra lutra) from southern Italy; 2 animals showed simultaneous immunohistochemical reactivity against morbilliviral antigen.
