Morphology and function of pinniped necks: The long and short of it
The Anatomical Record, EarlyView.Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.

Microstructural differences in the osteochondral unit of terrestrial and aquatic mammals
eLife, 2023 During evolution, animals have returned from land to water, adapting with morphological modifications to life in an aquatic environment. We compared the osteochondral units of the humeral head of marine and terrestrial mammals across species spanning a ...

Whales and Whaling: a Dance of Death [PDF]
Oryx, 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 ...

Drone Up! Quantifying Whale Behavior From a New Perspective Improves Observational Capacity
Frontiers in Marine Science, 2018 From our traditional boat-based horizontal perspective, marine megafauna behavioral observations are typically limited to animal surfacings. Achieving an aerial perspective has been restricted to brief helicopter or airplane based observations that are ...

The Anatomical Record, EarlyView.Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.

IET Networks, EarlyView., 2023 We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...
