Management of dental disease in eared seals (family Otariidae): a Delphi approach [PDF]

Frontiers in Veterinary Science
ObjectivePublished literature is sparse on topics associated with eared seal (otariid) dentistry. The objective of this study was to establish consensus on effective management of dental disease in otariids, using a Delphi approach.MethodsA total of 25 ...

Inflammatory Pseudotumour in Common Seal (Phoca vitulina): A Case Report. [PDF]

Vet Med Sci
A 19‐year‐old intact male common seal (Phoca vitulina) diagnosed with a chronic ulcer. Microbiology identified Vibrio alginolyticus. Radiography noted phalanx alterations. Macroscopic, histopathological, and immunohistochemical examinations revealed a neoplastic origin with a myofibroblastic phenotype. This report describes the first documented case of

Dokdo sea lion Zalophus japonicus genome reveals its evolutionary trajectory before extinction [PDF]

BMC Biology
Background The Dokdo sea lion (Zalophus japonicus), commonly referred to as Gangchi in Korea and the Japanese sea lion internationally, was endemic to the Northwest Pacific before its extinction in the 1950s. However, its origins, speciation, and genetic

Complete mitochondrial genome of the Galápagos sea lion, Zalophus wollebaeki (Carnivora, Otariidae): paratype specimen confirms separate species status [PDF]

ZooKeys, 2023
The endangered Galápagos sea lion (Zalophus wollebaeki) inhabits the Galápagos Islands off the coast of Ecuador. We present a complete mitochondrial genome (16 465 bp) of a female paratype from the collections of the Natural History Museum Oslo, Norway ...

Influence of Hypoxia, Dehydration and Salinity on Survival of Orthohalarachne Marine Mite Larvae: Limits to Dispersion [PDF]

Biology
Orthohalarachne attenuata and O. diminuata mites are parasites of the respiratory system of Pinnipeds. During hosts’ dives, mites must cope with changing conditions of oxygen availability in the nasal cavity.

Morphology and function of pinniped necks: The long and short of it. [PDF]

Anat Rec (Hoboken)
Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.

The impact of the land-to-sea transition on evolutionary integration and modularity of the pinniped backbone [PDF]

Communications Biology, 2023
In this study, we investigate how the terrestrial-aquatic transition influenced patterns of axial integration and modularity in response to the secondary adaptation to a marine lifestyle.

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds. [PDF]

Anat Rec (Hoboken)
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.

Histological analysis of incremental markings and crown growth characteristics in mandibular first molars of the red fox, Vulpes vulpes (Canidae, Mammalia). [PDF]

J Anat
This paper histologically analyzed incremental markings in dental enamel of red fox and grey wolf. Our results demonstrate that previous studies have misidentified these markings, which led to miscalculation of dental growth parameters. Abstract The present study analyzed incremental markings in the enamel of eight mandibular first molars (M1) of red ...

Phylogenetic allometric scaling of near basal breathing frequency in terrestrial, semi‐aquatic and aquatic mammals [PDF]

Experimental Physiology
We measured the BASAL breathing frequency following an overnight fast in adult, non‐pregnant/non‐lactating, inactive mammals ranging in body mass from 15 to 5520 kg.
