Intraspecific variation of cochlear morphology in bowhead and beluga whales
The Anatomical Record, EarlyView.Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

Genome-culture coevolution promotes rapid divergence of killer whale ecotypes
Nature Communications, 2016 Analysing population genomic data from killer whale ecotypes, which we estimate have globally radiated within less than 250,000 years, we show that genetic structuring including the segregation of potentially functional alleles is associated with ...

The Anatomical Record, EarlyView.Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Whaling and whale killing methods
Animal Welfare, 2013 Subsistence whale hunting dates back to 400AD (Perrinet al2009). Large-scale industrialised whaling to provide whale oil commenced in the late nineteenth century. Hunts escalated in the early 20th century and reports to the International Whaling Commission (IWC) show that over two million great whales were killed in hunts in the Southern Ocean between ...
