Aquatic Mammals (2009)
Heterochrony, the change in timing of developmental processes, is thought to be a key process shaping the numerous limb morphologies of tetrapods. Through a delayed offset in digit development, all…
Decrease stress; train your animals: The effect of handling methods on cortisol levels in harbour porpoises (Phocoena phocoena) under human care
Desportes, Geneviève; Buholzer, Lisette; Anderson-Hansen, Kirstin; Blanchet, Marie-Anne; Acquarone, Mario; Shephard, Gwyneth; Brando, Sabrina; Vossen, Arndt; Siebert, Ursula
Aquatic Mammals (2007)
Circulating cortisol levels are accepted as a sensitive indicator of acute stress in marine mammals, particularly in relation with capture and handling. The present study provides the first long-term monitoring…
Investigations of thyroid and stress hormones in free-ranging and captive harbor porpoises (Phocoena phocoena): A pilot study
Siebert, Ursula; Pozniak, Blazej; Anderson Hansen, Kirstin; Nordstrom, Gwyneth; Teilmann, Jonas; van Elk, Niels; Vossen, Arndt; Dietz, Rune;
Aquatic Mammals (2011)
Increasing anthropogenic activities in the marine environment are potential threats to the health of harbor porpoises by causing unnatural continuous stress to the animals. The present study was a first…
The behaviour of Hong Kong’s resident cetaceans: The Indo-Pacific humpbacked dolphin and the finless porpoise
Parsons, E. C. M.
Aquatic Mammals (1998)
A series of behavioural surveys were conducted in Hong Kong upon resident populations of Indo-Pacific hump-backed dolphins (Sousa chinensis) and finless porpoises (Neophocaena phocaenoides). The surveys were carried out from…
Morphometric comparison of the epidermis in several cetacean species
Jones, F. M.; Pfeiffer, C. J.
Aquatic Mammals (1994)
Epidermal thickness and relative papillary height of the skin from the urogenital region were compared with values from the ventral aspect of the flipper and the mid-dorsal body wall. Data…
Growth and reproduction of three populations of finless porpoise, Neophocaena phocaenoides, in Chinese waters
Gao, Anli; Zhou, Kaiya
Aquatic Mammals (1993)
We have 189 specimens available for this work. One-hundred and sixty-seven specimens from the Yangtze, Yellow Sea and South China Sea populations were aged and used in studying the growth…
Marginal papillae on the tongue of the Harbour porpoise (Phocoena phocoena), Bottlenose dolphin (Tursiops truncatus) and Commerson’s dolphin (Cephalorhynchus commersonii)
Kastelein, R. A.; Dubbeldam, J. L
Aquatic Mammals (1990)
This study shows that in Bottlenose dolphins and in Harbour porpoises the presence of marginal papillae is age related. In Bottlenose dolphins the papillae disappear around the age of 16…
Investigations on cetacean sonar VII: Underwater sounds of Neophocaena phocaenoides of the Japanese coastal population
Kamminga, C.; Kataoka, T.; Engelsma, F. J.
Aquatic Mammals (1986)
This paper describes the sonar sounds from four captive Neophocaena, two males and two females, which were tape recorded and processed with regard to their behaviour in the time and…
Experiences with harbour porpoises, Phocoena phocoena, in captivity: Mortality, autopsy findings and influence of the captive environment
Anderson, S. H.
Aquatic Mammals (1978)
This paper gives a survey of the fate of 67 harbour porpoises collected alive from Danish waters and kept in captivity for bioacoustical and physiological investigations. Even if the harbour…

Andersen, S. H.; Rebsdorff, A.
Aquatic Mammals (1976)
The purpose of the present study was to investigate the level of persistent chlorinated hydrocarbons and heavy metals in different tissues of four harbour porpoises caught at Danish coasts and…
