The role of oxytocin in the maternal behaviour of the grey seal (Halichoerus grypus) [PDF]
, 2015 The neuropeptide hormone oxytocin plays an integral role in mammalian reproductive endocrinology and behaviour. It has been utilised to study the physiological factors driving maternal behaviour in both laboratory and domestic mammals, but few studies ...

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds
The Anatomical Record, Volume 309, Issue 8, Page 2124-2150, August 2026.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.

Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT As breath‐hold divers, marine mammals must coordinate their use of both aerobic and anaerobic metabolism to maximize their time at depth. One indication of the relative reliance between these two energy‐producing systems is the aerobic dive limit (ADL), defined as the dive duration where post‐dive blood lactate concentrations surpass resting ...

Fatty Acid Composition in Blubber, Liver, and Muscle of Marine Mammals in the Southern Baltic Sea
Animals, 2020 To date, only limited results on the fatty composition in different tissues of the top predators in the Baltic Sea are available. In the current study, tissue samples of blubber, skeletal muscle, and liver from 8 harbour porpoise (Phocoena phocoena) and ...

Frontiers in Ecology and Evolution, 2022 Mammalian mothers usually provide their offspring with large quantities of immunoglobulins (antibodies) for circulation in blood, either trans-placentally before birth, via colostrum briefly thereafter, or, less commonly, from milk.

Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT Seal haulout behavior is of interest in relation to energetics and abundance estimation. To assess year‐round and diel haulout patterns and estimate correction factors, data were obtained from 100 seals (66 harbor and 34 gray seals) tagged with satellite transmitters in Kattegat and the western Baltic Sea during 2004–2017.
