Frontiers in Marine Science (2023)
The only native cetacean in German waters, the harbor porpoise (Phocoena phocoena), is impacted by numerous pathological lesions in the respiratory tract mainly caused by parasites or bacteria. Although harbor…
Contextual impacts on individual and synchronous breathing rate variations in three captive odontocete groups
Serres, Agathe; Hao, Yujiang; Wang, Ding
Zoo Biology (2020)
Breathing rates are often collected both in the wild and in captivity to inform on cetaceans' internal state. However, few studies have investigated the effect of various factors on this…
Social, reproductive and contextual influences on fecal glucocorticoid metabolites in captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) and bottlenose dolphins (Tursiops truncatus)
Serres, Agathe; Robeck, Todd; Deng, Xiaojun; Steinman, Karen; Hao, Yujiang; Wang, Ding
Journal of Zoological and Botanical Gardens (2020)
Although the use of fecal glucocorticoid metabolite (FGCM) measurements as non-invasive biomarkers for the stress response in mammals has increased, few studies have been conducted in odontocetes. We investigated if…
Body contacts and social interactions in captive odontocetes are influenced by the context: An implication for welfare assessment
Serres, Agathe; Hao, Yujiang; Wang, Ding
Animals (2020)
Research on the welfare of captive odontocetes has increased in recent years, but has been mostly focused on bottlenose dolphins (Tursiops truncatus). Few studies investigated potential welfare indicators using quantitative…
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…
Morphological analysis of the foramen magnum in finless porpoise (genus Neophocaena) using postmortem computed tomography 3D volume rendered images
Kot, Brian Chin Wing; Chan, Derek Kam Ping; Yuen, Adams Hei Long; Wong, Francis Ho Man; Tsui, Henry Chun Lok
Marine Mammal Science (2018)
...In the course of the pioneer virtopsy-driven stranding response program in Hong Kong (HK) waters, virtopsy using postmortem computed tomography (PMCT) has been implemented to augment conventional necropsy. A growing…
Characterization of milk protein composition of the Yangtze finless porpoise
Zeng, Xianyuan; Chen, Minmin; Liu, Zhigang; Yu, Daoping; Huang, Shiang-Lin; Yang, Jiwei; Fan, Fei; Wang, Ding; Hao, Yujiang; Nabi, Ghulam
Marine Mammal Science (2018)
...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…
The metabolic cost of swimming and reproduction in harbor porpoises (Phocoena phocoena) as predicted by a bioenergetic model
Gallagher, Cara A.; Stern, S. Jonathan; Hines, Ellen
Marine Mammal Science (2018)
While harbor porpoises currently enter San Francisco Bay year‐round, evidence suggests a disappearance that spanned approximately 65 yr. The range of energetic costs of basal metabolism, locomotion, thermoregulation, and reproduction…
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.…
Population structure and historical demography of eastern North Atlantic harbour porpoises inferred through mtDNA sequences
Tolley, K. A.; Rosel, P. E.
Marine Ecology Progress Series (2006)
The harbour porpoise Phocoena phocoena experiences high rates of incidental mortality in commercial fisheries, and in some areas these rates are sufficiently high to justify concern over population sustainability. Given…
