Taxonomic implications of morphometric analysis of earless seal limb bones [PDF]
Fossil Phocidae (earless seals) are mostly known from isolated postcranial material, forcing researchers to rely upon humeri and femora for the diagnosis of taxa and reconstruction of phylogeny.

The paradox of learned song in a semi‐solitary mammal
In past decades, pinnipeds have become a popular example of non‐human vocal production learning. In the case of harbor seals (Phoca vitulina), this is mainly owed to Hoover—a human‐raised seal pup, that once adult, imitated its former caretakers speech in a breeding context.

Extended maternal care past age 1 was common in Steller sea lions, but ranged geographically (e.g., 0.54–0.86 were weaned at age 1); where offspring were smallest, weaning was later. Earlier weaning and larger offspring were associated with reduced adult female survival but were unrelated to population trends, suggesting this trait may be optimized for

SEAL LOUSE (ECHINOPHTHIRIDAE) AS VECTORS FOR INVASIVE AND INFECTIOUS DISEASE AGENTS OF PINNIPEDS
The aim of the presented article is to analyze seal lice (Phthiraptera: Anoplura, Echinophthiridae) adaptation to aquatic environment – permanent parasites of pinnipeds, as well as available literature data about seal lice as pathogen vectors of their ...

New C‐Terminal Conserved Regions of Tafazzin, a Catalyst of Cardiolipin Remodeling
Cardiolipin interacts with many proteins of the mitochondrial inner membrane and, together with cytochrome C and creatine kinase, activates them. It can be considered as an integrating factor for components of the mitochondrial respiratory chain, which provides for an efficient transfer of electrons and protons.

A framework for integrating thermal biology into fragmentation research
Abstract Habitat fragmentation changes thermal conditions in remnant patches, and thermal conditions strongly influence organism morphology, distribution, and activity patterns. However, few studies explore temperature as a mechanism driving ecological responses to fragmentation. Here we offer a conceptual framework that integrates thermal biology into

A novel papillomavirus in a New Zealand fur seal (Arctocephalus forsteri) with oral lesions
Despite being the predominant seal species in the Australian-New Zealand region and serving as a key indicator of marine environmental health, little is known about infectious diseases in New Zealand fur seals (Long-nosed fur seal; Arctocephalus forsteri)
