Aquatic Mammals (2019)
Social group dynamics are known to impact odontocetes’ health and welfare in captivity. Social dominance and agonistic interactions that occur to establish and maintain these relationships might express themselves differently…
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…
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…
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…
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…
Does interspecific competition drive patterns of habitat use and relative density in harbour porpoises?
Díaz López, Bruno; Methion, Séverine
Marine Biology (2018)
Determining the drivers that are responsible for the fine-scale distribution of cetacean species is fundamental to understand better how they respond to changes in their environment. We utilized information theoretic…
The evolution of genital shape variation in female cetaceans
Orbach, Dara N.; Hedrick, Brandon; Würsig, Bernd; Mesnick, Sarah L.; Brennan, Patricia L. R.
Evolution (2017)
Male genital diversification is likely the result of sexual selection. Female genital diversification may also result from sexual selection, although it is less well studied and understood. Female genitalia are…
Responses of bottlenose dolphins and harbor porpoises to impact and vibration piling noise during harbor construction
Graham, Isla M.; Pirotta, Enrico; Merchant, Nathan D.; Farcas, Adrian; Barton, Tim R.; Cheney, Barbara; Hastie, Gordon D.; Thompson, Paul M.
Ecosphere (2017)
The development of risk assessments for the exposure of protected populations to noise from coastal construction is constrained by uncertainty over the nature and extent of marine mammal responses to…
Diet composition and food consumption rate of harbor porpoises (Phocoena phocoena) in the western Baltic Sea
Andreasen, Heidi; Ross, Stine D.; Siebert, Ursula; Andersen, Niels G.; Ronnenberg, Katrin; Gilles, Anita
Marine Mammal Science (2017)
Stomach content composition and prey-specific consumption rates of juvenile and adult harbor porpoises (Phocoena phocoena) were estimated from a data set including 339 stomachs collected over a 32 yr period…
Characterization of milk composition in narrow-ridged finless porpoises (Neophocaena asiaeorientalis) at different lactation stages
Zeng, Xianyuan; Huang, Shiang-lin; Qian, Zhengyi; Hao, Yujiang; Wang, Ding; Ji, Junhua; Nabi, Ghulam
Marine Mammal Science (2017)
Lactation plays a vital role in reproductive success, evolving with ecological adaptations of mammalian life histories. Knowledge of the lactation process in odontocetes is scarce and limited to a handful…
