Early stages of tooth development in the harbor porpoise Phocoena phocoena

The Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

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 ...

How adaptable are narwhal? A comparison of foraging patterns among the world's three narwhal populations [PDF]

Ecosphere, 2013
How organisms will fare in the face of climate change depends on their behavioral adaptability to changing conditions. Adaptability in foraging behavior will be particularly critical as food web changes are already occurring in Arctic regions. Stomach contents from narwhals (Monodon monoceros) in the Baffin Bay (BB) population have suggested that ...

Non-Autoregressive Neural Machine Translation with Enhanced Decoder Input

, 2018
Non-autoregressive translation (NAT) models, which remove the dependence on previous target tokens from the inputs of the decoder, achieve significantly inference speedup but at the cost of inferior accuracy compared to autoregressive translation (AT ...

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 ...

Distribution and Abundance of the Eastern Canada – West Greenland Bowhead Whale Population Based on the 2013 High Arctic Cetacean Survey

NAMMCO Scientific Publications, 2020
The hunting of bowhead whales (Balaena mysticetus) is an integral part of Inuit culture. An up-to-date abundance estimate of the entire Eastern Canada – West Greenland (EC-WG) bowhead population is necessary to support sustainable management of this ...

Killer Whale (Orcinus orca) pulsed calls in the Eastern Canadian Arctic [PDF]

, 2019
Killer whales produce pulsed calls, which are used for communication. Calls are highly stereotyped and repertoires are unique to individual pods. Discrimination amongst these calls and comparison of call repertoires between pods can help determine ...

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 ...
