Aquatic Mammals (2019)
Naval sonar systems produce signals that may affect the behavior of harbor porpoises (Phocoena phocoena), and behavioral responses may be influenced by the received signal and by the signal-to-noise ratio…
Agonistic interactions and dominance relationships in three groups of captive odontocetes: Method of assessment and inter-species/group comparison
Serres, Agathe; Hao, Yujiang; Wang, Ding
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…
Analysis of the bacterial diversity in the fecal material of the endangered Yangtze finless porpoise, Neophocaena phocaenoides asiaeorientalis
McLaughlin, Richard William; Chen, Minmin; Zheng, Jinsong; Zhao, Qingzhong; Wang, Ding
Molecular Biology Reports (2011)
The aim of this study was to determine the bacteria present in the fecal material of the endangered Yangtze finless porpoise, Neophocaena phocaenoides asiaeorientalis. Fecal samples were collected from 12…
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 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 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…
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…
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…
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.…
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…
