Change in the foraging strategy of female South American sea lions (Carnivora: Pinnipedia) after parturition [PDF]
Scientia Marina, 2010 This study tests the hypothesis that female South American sea lions shift from off-shore, pelagic prey to coastal, benthic prey after parturition in order to reduce the foraging trip duration and hence the time pups remain unattended on the beach ...

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.

Novel Approach to Inter-Onset-Interval Ratio Uncovers Music-Like Rhythmic Patterns in Budgerigar (Melopsittacus undulatus) Warble Song. [PDF]
Ann N Y Acad SciRecent work on non‐human animal vocalizations has offered new insights into rhythmicity. In an attempt to improve upon methods commonly used in animal rhythm research, we investigated the rhythmic structure of budgerigar song. Our proposed statistical approach showed rhythmicity in human music but not language, and uncovered non‐random structured ...

Targeted Nutritional Metabolomic Analysis of Marine Species (Tursiops truncatus, Phoca vitulina, Otaria flavescens and Pygoscelis papua). [PDF]
Vet Med SciThis study profiles the nutritional metabolomes of four marine species. Pygoscelis papua showed higher glucose, triglycerides, uric acid, and cholesterol, but lower albumin, total protein, urea, and inorganic phosphorus compared to others. Distinct metabolomic differences were also observed between T. truncatus and O.
