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…
First records of anomalously white harbor porpoises (Phocoena phocoena) from the Pacific ocean
Keener, William; Szczepaniak, Isidore; Ü, Adam; Webber, Marc; Stern, Jonathan
Journal of Marine Animals and Their Ecology (2011)
Anomalously white cetaceans are rarely seen, and only five records of white harbor porpoises (Phocoena phocoena) are found in the literature. We provide an updated list of those records, and…
Harbour porpoises (Phocoena phocoena) and wind farms: a case study in the Dutch North Sea
Scheidat, Meike; Tougaard, Jakob; Brasseur, Sophie; Carstensen, Jacob; van Polanen Petel, Tamara; Teilmann, Jonas; Reijnders, Peter
Environmental Research Letters (2011)
The rapid increase in development of offshore wind energy in European waters has raised concern for the possible environmental impacts of wind farms. We studied whether harbour porpoise occurrence has…
Auditory temporal resolution and evoked responses to pulsed sounds for the Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis)
Mooney, T. Aran; Li, Songhai; Ketten, Darlene R.; Wang, Kexiong; Wang, Ding
J Comp Physiol A (2011)
Temporal cues are important for some forms of auditory processing, such as echolocation. Among odontocetes (toothed whales, dolphins, and porpoises), it has been suggested that porpoises may have temporal processing…
Morphology of the odontocete melon and its implications for acoustic function
McKenna, Megan F.; Cranford, Ted W.; Berta, Annalisa; Pyenson, Nicholas D.
Marine Mammal Science (2011)
Toothed whales (crown Odontoceti) are unique among mammals in their ability to echolocate underwater, using specialized tissue structures. The melon, a structure composed of fat and connective tissue, is an…
Feeding habits and consumption by finless porpoises (Neophocaena asiaeorientalis) in the Yellow Sea
Park, Kyum-Joon; An, Yong-Rock; Lee, Young-Ran; Park, Ji-Eun; Moon, Dae-Yeon; Choi, Seok-Gwan
Korean Journal of Fisheries and Aquatic Sciences (2011)
We investigated the stomach contents of finless porpoises collected in the Yellow Sea. Prey organisms in the stomachs of 109 finless porpoises were identified as 11 species of fish, 8…
Tissue healing in two harbor porpoises (Phocoena phocoena) following long-term satellite transmitter attachment
Sonne, Christian; Teilmann, Jonas; Wright, Andrew J.; Dietz, Rune; Leifsson, Pall S.
Marine Mammal Science (2011)
(...) The present note evaluates, through postmortem findings, the effect of the attachment of satellite transmitters to the dorsal fin of two wild porpoises that were later lethally bycaught in…
Histopathological aspects and etiology of pneumonias in stranded marine mammals from Lima, Peru
Gonzales-Viera, Omar; Chavera, Alfonso; Yaipén-Llanos, Carlos; Perales-Camacho, Rosa
Brazilian Journal of Veterinary Pathology (2011)
This study presents the histopathologic features of pneumonia in stranded marine mammals on the coast of Lima, Peru during the period of May 2003 to December 2008. Lung samples of…
