Ji, Junhua; Nabi, Ghulam; Zeng, Xianyuan; Hao, Yujiang; Wang, Ding
Zoological Studies (2019)

The highly lipid-rich blubber in the hypodermis is a specialized structure that functions in thermoregulation, energy storage, buoyancy control, locomotion, and streamlining the body shape in marine mammals. The key…

Drago, Massimiliano; Valdivia, Meica; Bragg, Daniel; González, Enrique M.; Aguilar, Alex; Cardona, Luis
Estuarine, Coastal and Shelf Science (2020)

Detailed knowledge on habitat use by marine mammals is critical for understanding their ecological role and for adequate management. Here, we assess the habitat use patterns of thirteen species of…


Levels of polychlorinated biphenyls are still associated with toxic effects in harbor porpoises (Phocoena phocoena) despite having fallen below proposed toxicity thresholds

Williams, Rosie; ten Doeschate, Mariel; Curnick, David J.; Brownlow, Andrew; Barber, Jonathan L.; Davison, Nicholas J.; Deaville, Robert; Perkins, Matthew; Jepson, Paul D.; Jobling, Susan
Environmental Science & Technology (2020)

Polychlorinated biphenyls (PCBs) are toxic, persistent, and lipophilic chemical compounds that accumulate to high levels in harbor porpoises (Phocoena phocoena) and other cetaceans. It is important to monitor PCBs in…
