Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

open access: yesThe Anatomical Record, EarlyView.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Using Ancient DNA Analysis and Radiocarbon Dating to Determine the Provenance of an Unusual Whaling Artifact

open access: yesFrontiers in Ecology and Evolution, 2020
Natural history collections provide a critical temporal view of past biodiversity and are instrumental in the study of extinct populations. However, the value of historical specimens relies on correct species identification, collection date and ...

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Newspaper Reporting of Whaling in Australia and Japan: A Comparative Content Analysis

open access: yesNew Voices, 2014
The ongoing dispute over whaling is a significant issue of conflict between Australia and Japan. It appears that the print media in each country supports the dominant opinion: anti-whaling in Australia, and pro-whaling in Japan.

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint

open access: yesThe Anatomical Record, EarlyView.
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Quantifying the energy stores of capital breeding humpback whales and income breeding sperm whales using historical whaling records

open access: yesRoyal Society Open Science, 2017
Cetacean energy stores are known to vary according to life history, reproductive status and time of year; however, the opportunity to quantify these relationships is rare. Using a unique set of historical whaling records from Western Australia (1952–1963)

Whales and Whaling: a Dance of Death [PDF]

open access: yesOryx, 1975
The whaling industry and its raw material, the whale stocks of the world, continue their grim Totentanz towards their mutual extinction. The most significant event of the 27th meeting of the International Whaling Commission in London in June, and one of the least publicised, was the Soviet announcement that next season they would have only two instead ...

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

open access: yesThe Anatomical Record, EarlyView.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland
