A Narwhal in the Thames Estuary [PDF]

Nature, 1949
THE recent stranding of a narwhal (Monodon monoceros) at Rainham, Essex, is a record of considerable interest. This species is usually limited to Arctic waters, although it occasionally penetrates into the North Sea. The infrequency of its occurrence off the British coast may be gauged by the fact that since 1588, when one was found on the coast of ...

Vocal sequences in narwhals (Monodon monoceros) [PDF]

The Journal of the Acoustical Society of America, 2020
Sequences are indicative of signal complexity in vocal communication. While vocal sequences are well-described in birds and terrestrial mammals, the extent to which marine mammals use them is less well understood. This study documents the first known examples of sequence use in the narwhal (Monodon monoceros), a gregarious Arctic cetacean. Eight female

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Coalition Formation for Sustainable Blockchain Governance: Insights From the Hedera Case

Information Systems Journal, EarlyView.
ABSTRACT Sustainable governance is essential for blockchain networks to achieve widespread adoption and deliver long‐term business value. Prior blockchain initiatives indicate that inadequate governance structures often lead to limited adoption or eventual project failure, underscoring the importance of decentralised governance for building resilient ...

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Intraspecific variation of cochlear morphology in bowhead and beluga whales

The Anatomical Record, Volume 309, Issue 6, Page 1514-1529, June 2026.
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 ...
