Bisack, Kathryn D.; Magnusson, Gisele
North American Journal of Fisheries Management (2014)
Marine mammal stock assessments provide information that is valuable to public sector management and the private fishing sector; however, data are costly to collect. The precautionary approach, which is widely…
First report of infestation by a parasitic copepod (Pennella balaenopterae) in a harbour porpoise (Phocoena phocoena) from the Aegean Sea: A case report

An adult, female harbour porpoise (Phocoena phocoena relicta) was found stranded on the southern Aegean Sea coast of Turkey. Thirteen holes made by copepods were observed on the lateral sides…
Unique feeding morphology in a new Prognathous extinct porpoise from the Pliocene of California
Racicot, Rachel A.; Deméré, Thomas A.; Beatty, Brian L.; Boessenecker, Robert W.
Current Biology (2014)
Modern porpoises (Odontoceti: Phocoenidae) are some of the smallest cetaceans and usually feed near the seafloor on small fish and cephalopods [1, 2 and 3]. Within both extinct and extant…
Beyond parasitism: Hepatic lesions in stranded harbor porpoises (Phocoena phocoena) without trematode (Campula oblonga) infections

Veterinary Pathology (2014)
The liver can be an indicator of the health of an individual or of a group, which can be especially important to identify agents that can cause disease in multiple…
Effect of series of 1 to 2 kHz and 6 to 7 kHz up-sweeps and down-sweeps on the behavior of a harbor porpoise (Phocoena phocoena)
Kastelein, Ronald; Schop, Jessica; Gransier, Robin; Steen, Nele; Jennings, Nancy
Aquatic Mammals (2014)
To compare the effect of naval sonar up-sweeps and down-sweeps on the behavior of harbor porpoises, a harbor porpoise in a large pool was exposed to simulated low- and mid-frequency…
