Histological investigations on the thyroid glands of marine mammals (Phoca vitulina, Phocoena phocoena) and the possible implications of marine pollution [PDF]

, 1993
In 1988 and 1989, thousands of harbor seals (Phoca vitulina) died in the North Sea from phocine distemper infection. The morphology of thyroid glands from 40 harbor seals found dead on the North Sea coastlines of Schleswig-Holstein, Federal Republic of ...

Early evolution of sexual dimorphism and polygyny in Pinnipedia [PDF]

, 2018
Sexual selection is one of the earliest areas of interest in evolutionary biology. And yet, the evolutionary history of sexually dimorphic traits remains poorly characterized for most vertebrate lineages. Here we report on evidence for the early evolution of dimorphism within a model mammal group, the pinnipeds.

Beyond Serology: A Meta‐Analysis of Advancements in Molecular Detection of Brucella spp. in Seronegative Animals and Biological Samples

Veterinary Medicine and Science, Volume 11, Issue 1, January 2025.
Molecular diagnostics, such as PCR and biosensor‐based techniques, offer high sensitivity in detecting Brucella spp. in seronegative animals, overcoming the limitations of traditional serological methods. The pooled detection rate of 35.08% suggests a substantial number of hidden carriers.

Characterization of pinniped vibrissal type and number

Marine Mammal Science, Volume 41, Issue 1, January 2025.
Abstract Pinnipeds have vibrissae with which they can explore their environment. Two vibrissal parameters that differ in pinnipeds are shape and number. Regarding shape, most phocids have undulated vibrissae, whereas the vibrissae of a few phocids, all otariids and walruses are smooth.

Covariation in the Craniocervical Junction of Carnivora

Journal of Morphology, Volume 285, Issue 11, November 2024.
The craniocervical junction in mammals is a biomechanically unique region that involves the occiput and two specialized vertebrae: the ring‐shaped atlas (CV1) and the axis (CV2) with its peculiar odontoid process (Dens). In Carnivora, the present study indicates that quantitative variation in CV1 morphology reflects a functional signal, while CV2 ...
