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…
Geographic variation of skeletal ontogeny and skull shape in the harbour porpoise (Phocoena phocoena)
Galatius, A.; Gol’din, P. E.
Canadian Journal of Zoology (2011)
All extant porpoise species show paedomorphic skeletal traits. These traits are hypothesized to be connected with rapid growth to reproductive size and could thus show geographic variation according to ecological…
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…
Single source sound production and dynamic beam formation in echolocating harbour porpoises (Phocoena phocoena)
Madsen, P. T.; Wisniewska, D.; Beedholm, K.
Journal of Experimental Biology (2010)
Echolocating toothed whales produce high-powered clicks by pneumatic actuation of phonic lips in their nasal complexes. All non-physeteroid toothed whales have two pairs of phonic lips allowing many of these…
Marine mammal records from Iran
Braulik, G. T.; Ranjbar, S.; Owfi, F.; Aminrad, T.; Dakhteh, S. M. H.; Kamrani, E.; Mohsenizadeh, F.
Journal of Cetacean Research and Management (2010)
Iran has 1,700km of coastline that borders the Persian Gulf and the Arabian Sea in the northwest Indian Ocean. Apart from a handful of records, almost nothing is known about…
Click communication in harbour porpoises Phocoena phocoena
Clausen, K. T.; Wahlberg, M.; Beedholm, K.; Deruiter, S.; Madsen, P. T.
Bioacoustics (2010)
Sound plays an important role for toothed whales in foraging and communication. However, little is known about acoustic communication in the toothed whale species that only produce narrow band high…
Morphology and microanatomy of harbor porpoise (Phocoena phocoena) dorsal fin tubercles
Ginter, Carly C.; Böttger, S. Anne; Fish, Frank E.
Journal of Morphology (2010)
The unique pattern of small tubercles on the leading edge of the dorsal fins of harbor porpoises (Phocoena phocoena) has been widely noted in the literature, though their structure or…
Gas bubble disease in harbor porpoises (Phocoena phocoena) stranded in British Columbia
Raverty, Stephen A.; Spavin, Lisa; Cottrell, Paul; Ford, John; Hall, Anna; Gaydos, Joe; Haulena, Martin; Ivančić, Marina
Conference of the International Association for Aquatic Animal Medicine (2010)
Harbour porpoises (Phocoena phocoena) are among the most abundant small cetaceans in the northeastern Pacific and there is a distinct bimodal seasonal stranding trend. Increased numbers of animals present in…
Persistent organic pollutants and methoxylated PBDEs in harbour porpoises from the North Sea from 1990 until 2008: Young wildlife at risk?
Weijs, Liesbeth; van Elk, Cornelis; Das, Krishna; Blust, Ronny; Covaci, Adrian
Science of The Total Environment (2010)
In the European North Sea, harbour porpoises are top predators with relatively long life spans and a limited capacity for metabolic biotransformation of contaminants compared to some other marine mammal…
Paedomorphosis in two small species of toothed whales (Odontoceti): How and why?
Galatius, Anders
Biological Journal of the Linnean Society (2010)
To evaluate and assess the ontogenetic background for paedomorphosis in phocoenids, samples of 144 harbour porpoises, 81 white-beaked dolphins, and 130 Commerson's dolphins were compared in terms of the development…
