Frontiers in Marine Science, 2022 In Antarctica, abundant consumers rely on Antarctic krill for food, but krill are also the subject of a commercial fishery. The fishery overlaps in time and space with the foraging areas of these consumers, thus potential competition between krill ...

Humpback and Fin Whaling in the Gulf of Maine from 1800 to 1918 [PDF]
, 2002 The history of whaling in the Gulf of Maine was reviewed primarily to estimate removals of humpback whales, Megaptera novaeangliae, especially during the 19th century.

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model
Integrative Zoology, EarlyView.UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Male Bowhead Whale Reproductive Histories Inferred from Baleen Testosterone and Stable Isotopes
Integrative Organismal Biology, 2022 Synopsis Male mammals of seasonally reproducing species typically have annual testosterone (T) cycles, with T usually peaking during the breeding season, but occurrence of such cycles in male mysticete whales has been difficult to confirm.

Salishicetus meadi, a new aetiocetid from the late Oligocene of Washington State and implications for feeding transitions in early mysticete evolution [PDF]
Royal Society Open Science, 2018 Living baleen whales, or Mysticeti, lack teeth and instead feed using keratinous baleen plates to sieve prey-laden water. This feeding strategy is profoundly different from that of their toothed ancestors, which processed prey using the differentiated ...

Scaling of swimming performance in baleen whales [PDF]
Journal of Experimental Biology, 2019 The scale-dependence of locomotor factors have long been studied in comparative biomechanics, but remain poorly understood for animals at the upper extremes of body size. Rorqual baleen whales include the largest animals, but we lack basic kinematic data about their movements and behavior below the ocean surface.

Journal for Eighteenth-Century Studies, EarlyView.Abstract The final Stuart monarch, Queen Anne, has often been overlooked in studies of visual and material culture, particularly of fashion and dress. This article is the first to undertake a qualitative and quantitative analysis of the wardrobe accounts of Queen Anne, situating her consumption within the context of the eighteenth‐century fashion ...

Soviet Illegal Whaling: The Devil and the Details [PDF]
, 2011 In 1948, the U.S.S.R. began a global campaign of illegal whaling that lasted for three decades and, together with the poorly managed “legal” whaling of other nations, seriously depleted whale populations.
