Genital interactions during simulated copulation among marine mammals

Orbach, Dara N.; Kelly, Diane A.; Solano, Mauricio; Brennan, Patricia L. R.
Proceedings of the Royal Society B: Biological Sciences (2017)

Genitalia are morphologically variable across many taxa and in physical contact during intromission, but little is known about how variation in form correlates with function during copulation. Marine mammals offer…

...Milk protein composition likely varies between lactation stages in the finless porpoise (Zeng et al. 2017). Zeng et al. (2017) indicate that crude protein concentration is much higher in colostrum…


Group characteristics, site fidelity, and photo-identification of harbor porpoises, Phocoena phocoena, in Burrows Pass, Fidalgo Island, Washington

Elliser, Cindy R.; MacIver, Katrina H.; Green, Michelle
Marine Mammal Science (2017)

Little is known about harbor porpoises at the individual level or local group structure. Group characteristics, site fidelity, and photo‐identification of harbor porpoises were investigated off Fidalgo Island, Washington State.…


Two decades’ variation of trace elements in bones of the endangered East Asian Finless Porpoise (Neophocaena asaeorientalis sunameri) from the East China Sea, China

Hao, Xiuqing; Shan, Hong; Wu, Caiwen; Zhang, Di; Chen, Bingyao
Biological Trace Element Research (2020)

There has been increasing concern about trace element accumulation in finless porpoises over the past decades, while the long-term variation of its concentration has been little known. Since most soft…


The frequency of solitary behaviours in captive odontocetes is modulated by environmental and social factors

Serres, Agathe; Hao, Yujiang; Wang, Ding
International Journal of Comparative Psychology (2019)

The number of welfare-oriented studies is increasing in animals under human care, including odontocetes. However, validated welfare indicators are lacking for captive odontocetes. We studied the effect of several conditions…
