Factors affecting harp seal (Pagophilus groenlandicus) strandings in the Northwest Atlantic. [PDF]

open access: yesPLoS ONE, 2013
The effects of climate change on high latitude regions are becoming increasingly evident, particularly in the rapid decline of sea ice cover in the Arctic.

The Evolutionary History of the Extinct Baltic Sea Harp Seal Population [PDF]

open access: yesEcology and Evolution
The now‐extinct harp seal population that inhabited the Baltic Sea from the Mesolithic to the Iron Age is an enigma. It occurred outside the species' contemporary Arctic range, likely deviated from typical harp seal migratory behaviour, and experienced ...

The frequency response of the vibrissae of harp seal, Pagophilus Groenlandicus, to sound in air and water. [PDF]

open access: yesPLoS ONE, 2013
The motion of isolated seal vibrissae due to low frequency sound in air has been measured using a microscope with a video camera and modeled using an FEM method with good agreement between the measurements and the model; the model has also been used to ...

A model for maxilloturbinate morphogenesis in seals. [PDF]

open access: yesPLoS ONE
The nasal cavities of mammals contain the maxilloturbinate bones, which are involved in reducing heat and water losses. The maxilloturbinates of Arctic seals develop into particularly elaborate labyrinthine patterns, which are well adapted to retain heat

Hiding in plain sight: the biomolecular identification of pinniped use in medieval manuscripts [PDF]

open access: yesRoyal Society Open Science
The survival of medieval manuscripts in their original bindings remains a rare occurrence. Taking advantage of the diversity of bindings in Cistercian libraries such as Clairvaux and its daughter abbeys during the twelfth and thirteenth centuries, this ...

Elevated antioxidant defence in the brain of deep-diving pinnipeds [PDF]

open access: yesFrontiers in Physiology, 2022
While foraging, marine mammals undertake repetitive diving bouts. When the animal surfaces, reperfusion makes oxygen readily available for the electron transport chain, which leads to increased production of reactive oxygen species and risk of oxidative ...

Phocine Distemper Virus: Current Knowledge and Future Directions [PDF]

open access: yesViruses, 2014
Phocine distemper virus (PDV) was first recognized in 1988 following a massive epidemic in harbor and grey seals in north-western Europe. Since then, the epidemiology of infection in North Atlantic and Arctic pinnipeds has been investigated.

Food consumption estimates of Barents Sea harp seals

open access: yesNAMMCO Scientific Publications, 2004
The consumption of various prey species, required by the Barents Sea harp seal (Phoca groenlandica) stock in order to cover their energy demands, has been estimated by combining data on the energy density of prey species and on seasonal variations in the

The effects of climate change on harp seals (Pagophilus groenlandicus). [PDF]

open access: yesPLoS ONE, 2012
Harp seals (Pagophilus groenlandicus) have evolved life history strategies to exploit seasonal sea ice as a breeding platform. As such, individuals are prepared to deal with fluctuations in the quantity and quality of ice in their breeding areas.
