Marine Biology (2011)
The existence of three distinct populations is widely accepted for the finless porpoise (Neophocaena phocaenoides) in Chinese waters: the Yellow Sea, Yangtze River, and South China Sea populations. Here, we…
Revision of the taxonomy of finless porpoises (genus Neophocaena): the existence of two species
Jefferson, Thomas A.; Wang, John Y.
Journal of Marine Animals and Their Ecology (2011)
Due to extensive morphological variation and inadequately-sampled or poorly-designed studies, the taxonomy of the finless porpoises (genus Neophocaena) has been controversial for some time. An uneasy stability with the arrangement…
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…
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…
Genome-wide SNP and population divergence of finless porpoises
Li, S.; Xu, S.; Wan, H.; Ji, H.; Zhou, K.; Yang, G.
Genome Biology and Evolution (2013)
Single nucleotide polymorphisms (SNPs) are rapidly becoming the population genomic markers in addressing ecology, evolution, and conservation issues for their high capacity to access variability across the genome. We isolated…
Hearing pathways in the Yangtze finless porpoise, Neophocaena asiaeorientalis asiaeorientalis
Mooney, T. A.; Li, S.; Ketten, D. R.; Wang, K.; Wang, D.
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…
