Expanding the geographic and geochronologic range of early pinnipeds: New specimens of Enaliarctos from Northern California and Oregon [PDF]
Acta Palaeontologica Polonica, 2018 The early pinnipedimorph Enaliarctos was a marine-adapted carnivore with dental and locomotor features intermediate between terrestrial arctoids and living pinnipeds.

Impact of the terrestrial-aquatic transition on disparity and rates of evolution in the carnivoran skull. [PDF]
, 2015 Which factors influence the distribution patterns of morphological diversity among clades? The adaptive radiation model predicts that a clade entering new ecological niche will experience high rates of evolution early in its history, followed by a ...

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 ...

The Utility of Combining Stable Isotope and Hormone Analyses for Marine Megafauna Research
Frontiers in Marine Science, 2018 Stable isotope and hormone analyses offer insight into the health, stress, nutrition, movements, and reproduction of individuals and populations. Such information can provide early warning signs or more in-depth details on the ecological and conservation

Taxonomic implications of morphometric analysis of earless seal limb bones [PDF]
Acta Palaeontologica Polonica, 2019 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.

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.
