Bony nares air pressure and nasal plug muscle activity during click production in the harbour porpoise, Phocoena phocoena, and the bottlenosed dolphin, Tursiops truncatus

Amundin, M.; Andersen, S.H.
Journal of Experimental Biology (1983)

Sound production mechanisms have been studied in two delphinid species - the harbour porpoise, Phocoena phocoena (L.), and the bottlenosed dolphin, Tursiops truncatus (Montagu). It was found that, in both…


Interspecific variation of ontogeny and skull shape among porpoises (Phocoenidae)

Galatius, Anders; Berta, Annalisa; Frandsen, Marie Schou; Goodall, R. Natalie P.
Journal of Morphology (2010)

All extant members of Phocoenidae (porpoises) have been characterized as pedomorphic based on skeletal characters. To investigate the ontogenetic background for pedomorphosis and assess interspecific differences in ontogeny among phocoenids,…


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…


Phylogenetic relationships among the true porpoises (Cetacea: Phocoenidae)

Rosel, P; Haygood, M; Perrin, W
Molecular Phylogenetics and Evolution (1995)

Portions of the cytochrome b gene and control region of the mitochondrial DNA molecule were sequenced to investigate systematic relationships among the six extant species of true porpoises, (Cetacea: Phocoenidae).…


Population genetic structure of the Yangtze Finless Porpoise (Neophocaena phocaenoides asiaeorientalis): Implications for management and conservation

Zheng, Jin-Song; Xia, Jun-Hong; He, Shun-Ping; Wang, Ding
Biochem Genet (2005)

Understanding the population genetic structure is a prerequisite for conservation of a species. The degree of genetic variability characteristic of the mitochondrial DNA control region has been widely exploited in…


Analysis of global and local population stratification of finless porpoises Neophocaena phocaenoides in Chinese waters

Li, Xiang; Liu, Yingying; Tzika, Athanasia C.; Zhu, Qian; Van Doninck, Karine; Milinkovitch, Michel C.
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…
