Journal of Experimental Biology (2013)
How an animal receives sound may influence its use of sound. While ‘jaw hearing’ is well supported for odontocetes, work examining how sound is received across the head has been…
Age and reproduction of the finless porpoises, Neophocaena asiaeorientalis , in the Yellow Sea, Korea
Lee, Young Ran; An, Yong Rock; Park, Kyum Joon; Sohn, Hawsun; An, Du Hae; Kim, Su Am
Animal Cells and Systems (2013)
A total of 116 finless porpoises, Neophocaena asiaeorientalis, were collected in the Yellow Sea off Korea. About 111 specimens were incidentally caught by stow nets on anchors from March to…
Contingent Valuation of Yangtze Finless Porpoises in Poyang Lake, China
Dong, Yanyan
(2013)
Yangtze finless porpoises (YFPs) are the only fresh water adapted porpoises in the world, living in the middle and downstream of the Yangtze River, in China. They are facing the…
Morphology and variation in porpoise (Cetacea: Phocoenidae) cranial endocasts
Racicot, Rachel A.; Colbert, Matthew W.
The Anatomical Record (2013)
Evolution of endocranial anatomy in cetaceans is important from the perspective of echolocation ability, intelligence, social structure, and alternate pathways for circulation to the brain. Apart from the importance of…
Preliminary study on genetic differences between two species of finless porpoises, genus Neophocaena, with lack of genetic divergence between two subspecies of the narrow-ridged finless porpoise, N. asiaeorientalis: cytochrome b sequence analyses
Koh, H. S.; Jo, J. E.; Ahn, N. H.; Lee, J. H.; Kim, K. S.; Jin, C. W.
Journal of Cetacean Research and Management (2013)
Using samples from bycaught finless porpoises, cytochrome b sequences were analysed and phylogenetic trees were constructed. The aims were to: (1) determine genetic divergences within the genus Neophocaena; (2) examine…
Accumulation of hydroxylated polychlorinated biphenyls (OH-PCBs) and implications for PCBs metabolic capacities in three porpoise species
Ochiai, Mari; Nomiyama, Kei; Isobe, Tomohiko; Mizukawa, Hazuki; Yamada, Tadasu K.; Tajima, Yuko; Matsuishi, Takashi; Amano, Masao; Tanabe, Shinsuke
Chemosphere (2013)
The present study investigated polychlorinated biphenyls (PCBs) and hydroxylated metabolites of PCBs (OH-PCBs) in blood from three porpoise species: finless porpoises (Neophocaena phocaenoides), harbor porpoises (Phocoena phocoena), and Dall’s porpoises…
The development of spatial positions between mother and calf of Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) maintained in captive and seminatural environments
Xian, Yijie; Wang, Kexiong; Jiang, Wenhua; Zheng, Bangyou; Wang, Ding
Aquatic Mammals (2012)
For many toothed whales, two predominant and multifunctional spatial positions occur between a mother/calf pair after birth: (1) the echelon position and (2) the infant position. Other nonpredominant positions also…
Genetic evaluation and development prognosis on ex situ conserved Yangtze finless porpoises living in Tian-E-Zhou National Natural Reserve
Zhou, Zhao; Zheng, Jin-Song; Chen, Min-Min; Zhao, Qing-Zhong; Wang, Ding
Acta Hydrobiologica Sinica (2012)
The Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) is a unique freshwater subspecies of Neophocaena phocaenoides, which is endemic to the Yangtze River of China and now is critically endangered. As…
Comparative morphology of porpoise (Cetacea: Phocoenidae) pterygoid sinuses: Phylogenetic and functional implications
Racicot, Rachel A.; Berta, Annalisa
Journal of Morphology (2012)
High-resolution X-ray computed tomographic scans were used to examine pterygoid sinus morphology within extant porpoise species and one delphinid (Tursiops truncatus), in order to consider: 1) intraspecific and interspecific variation…
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…
