Journal of Mammalogy (2008)
We examined the stomach contents of 87 finless porpoises (Neophocaena phocaenoides) in the Ariake Sound–Tachibana Bay area and Omura Bay in western Kyushu, Japan, between 1987 and 1992. Fish (Gobiidae…
Mate guarding in male Dall’s porpoises (Phocoenoides dalli)
Willis, Pamela M.; Dill, Lawrence M.
Ethology (2007)
Mate guarding, whereby a male closely attends and defends a fertile female from extra-pair matings, is one mating tactic males of many species use to protect their paternity. Although female…
A decade of harbour porpoise occurrence in German waters—Analyses of aerial surveys, incidental sightings and strandings
Siebert, Ursula; Gilles, Anita; Lucke, Klaus; Ludwig, Martje; Benke, Harald; Kock, Karl-Hermann; Scheidat, Meike
Journal of Sea Research (2006)
Data on the occurrence of harbour porpoises (Phocoena phocoena) in German waters from 1988 to 2002 were collected from dedicated aerial surveys, incidental sightings and strandings. Aerial surveys conducted in…
Reproductive seasonality and maturity of male Neophocaena phocaenoides asiaeorientalis in captivity: A case study based on the hormone evidence
Daoquan, Chen; Yujiang, Hao; Qingzhong, Zhao; Ding, Wang
Marine and Freshwater Behaviour and Physiology (2006)
To provide hormone evidence on reproductive seasonality and maturity of the Yangtze finless porpoise, the authors monitored the monthly variations of serum reproductive hormones of a male Yangtze finless porpoise…
Review on breeding biology of Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis)
Hao, Yujiang; Wang, Ding; Zhang, Xianfeng
Acta Theriologica Sinica (2006)
There are three Neophocaena phocaenoides subspecies recognized in Chinese waters: South China Sea population, N. p. phocaenoides; Yellow Sea population, N. p. sunameri; and Yangtze population, N. p. asiaeorientalis. The…
Parentage determination of an isolated Yangtze finless porpoise population Neophocaena phocaenoides asiaeorientalis in the Yangtze Tian-e-Zhou Baiji National Natural Reserve based on molecular data
Junhong, Xia; Jinsong, Zheng; Limei, Xu; Ding, Wang
Progress in Natural Science (2005)
Reproductive behaviors are poorly known for the Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis. In this study, the parentage of an isolated Yangtze finless porpoise population inhabiting the Yangtze Tian-e-Zhou Baiji…
Stranding patterns of harbour porpoises (Phocoena phocoena) in the German North and Baltic Seas: When does the birth period occur?
Hasselmeier, I.; Abt, K. F.; Adelung, D.; Siebert, U.
Journal of Cetacean Research and Management (2004)
Stranded harbour porpoises were analysed to investigate differences in stranding patterns along the North and Baltic Sea coasts of Schleswig-Holstein, Germany. A total of 1,015 stranded or bycaught harbour porpoises…

This report summarises the available knowledge on odontocete (toothed whale) distribution, behaviour, migration and threats and was compiled for the Bonn Secretariat of CMS.
Natural hybridization between Dall’s porpoises (Phocoenoides dalli) and harbour porpoises (Phocoena phocoena)
Willis, Pamela M; Crespi, Bernard J; Dill, Lawrence M; Baird, Robin W; Hanson, M Bradley
Can. J. Zool. (2004)
Natural hybridization occurs rarely in mammals compared with other taxonomic groups of animals. Cetaceans appear unique among mammals in exhibiting striking karyological uniformity, which suggests that they have the potential…
Harbour porpoises (Phocoena phocoena) in the North Atlantic: Biological parameters
Lockyer, Christina
NAMMCOSP (2003)
Biological parameters for harbour porpoises are reviewed throughout their range in the North Atlantic. Most information is based on studies of a combination of directed catches, bycatches and strandings. All…
