Report of the International Whaling Commission (1993)
We present the results of an aerial line transect census of cetaceans along the California coast during March and April 1991. This survey was the first of two aerial surveys…
Investigations on the osteology and the functional morphology of the flipper of whales and dolphins (Cetacea)
Benke, H.
Investigations on Cetacea (1993)
Of the 79 recent species of cetaceans 51 have been examined relative to the osteology of the flipper and the scapula and, in addition to this, video-recordings of 13 different…
Prevalence of morbilliviruses among pinniped and cetacean species
Visser, I. K. G.; Van Bressem, M. F.; Van de Bildt, M. W. G;; Groen, J.; Orvell, C.; Raga, J. A.; Osterhaus, A. D. M. E.;
Revue Scientifique et Technique de l'OIE (1993)
Since 1987, morbillivirus infections have caused serious disease outbreaks with high mortality among aquatic mammals. Baikal seals (Phoca sibirica) in Siberia were involved in an outbreak caused by a virus…
Skin disease in wild cetaceans from British waters
Baker, J.R.
Aquatic Mammals (1992)
Eighty-one dead cetaceans of a variety of species and from British waters were examined for evidence of skin disease and 69% were found to be affected. The most common conditions…
Status of small cetacean populations in the Black Sea: Review of current information and suggestions for future research
Buckland, S. T.; Smith, T. D.; Cattanach, K. L.
Report of the International Whaling Commission (1992)
The available information on the status of populations of three species of dolphins in the Black Sea is reviewed. These populations were subject to a commercial fishery from 1870 to…
Facial anatomy and potential function of facial structures for sound production in the harbor porpoise (Phocoena phocoena) and Dall’s porpoise (Phocoenoides dalli)
Curry, Barbara E.
Can. J. Zool. (1992)
Structural modifications of the odontocete skull and nasal passages have shifted the position of the facial bones and associated soft anatomy to the dorsal aspect of the head. The facial…
Mercury contamination of the harbour porpoise Phocoena phocoena and other cetaceans from the North Sea and the Kattegat
Joiris, C. R.; Holsbeek, L.; Bouquegneau, JM.; Bossicart, M.
Water, Air, and Soil Pollution (1991)
Total Hg levels were determined in 17 harbour porpoises Phocoena phocoena collected in the North Sea and the Kattegat (muscle, liver and kidney), as well as in a sperm whale…
Forehead anatomy of Phocoena phocoena and Cephalorhynchus commersonii: 3-dimensional computer reconstructions with emphasis on the nasal diverticula
Amundin, Mats; Cranford, Ted
Sensory Abilities of Cetaceans (1990)
(...) Watkins et al. (1977) and Dudok van Heel (1981) point to similarity in sound output in Cephalorhynchus and Phocoena, and suggest that it may be the result of convergent…
Best vision zones in the retinae of some cetaceans
Mass, Alla; Supin, Alexander
Sensory Abilities of Cetaceans (1990)
(...) Organization of the visual system in Cetacea still remains unclear in many respects. Of special interest are data on ganglion cell distribution in the retina. It is related closely…
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…
