Changes in click source levels with distance to targets: Studies of free-ranging white-beaked dolphins Lagenorhynchus albirostris and captive harbour porpoises Phocoena phocoena

Atem, Ana Carolina G.; Rasmussen, Marianne H.; Wahlberg, Magnus; Petersen, Hans C.; Miller, Lee A.;
Bioacoustics (2009)

Probably all odontocetes use echolocation for spatial orientation and detection of prey. We used a four hydrophone “Y” array to record the high frequency clicks from free-ranging White-beaked Dolphins Lagenorhynchus…


Organization and number of orexinergic neurons in the hypothalamus of two species of Cetartiodactyla: A comparison of giraffe (Giraffa camelopardalis) and harbour porpoise (Phocoena phocoena)

Dell, Leigh-Anne; Patzke, Nina; Bhagwandin, Adhil; Bux, Faiza; Fuxe, Kjell; Barber, Grace; Siegel, Jerome M.; Manger, Paul R.
Journal of Chemical Neuroanatomy (2012)

The present study describes the organization of the orexinergic (hypocretinergic) neurons in the hypothalamus of the giraffe and harbour porpoise – two members of the mammalian Order Cetartiodactyla which is…


Comparing distribution of harbour porpoises (Phocoena phocoena) derived from satellite telemetry and passive acoustic monitoring

Cetacean monitoring is essential in determining the status of a population. Different monitoring methods should reflect the real trends in abundance and patterns in distribution, and results should therefore ideally…


Ontogenetic allometry and body composition of harbour porpoises (Phocoena phocoena, L.) from the western North Atlantic

McLellan, W. A.; Koopman, H. N.; Rommel, S. A.; Read, A. J.; Potter, C. W.; Nicolas, J. R.; Westgate, A. J.; Pabst, D. A.
Journal of Zoology (2002)

North Atlantic harbour porpoises Phocoena phocoena (L.) face considerable energetic challenges, as they are relatively small marine mammals with an intense reproductive schedule and a cold-water habitat. Post-natal growth of…


Comparative anatomy of the bony labyrinth of extant and extinct porpoises (Cetacea: Phocoenidae)

Racicot, Rachel A.; Gearty, William; Kohno, Naoki; Flynn, John J.
Biological Journal of the Linnean Society (2016)

The inner ear anatomy of cetaceans, now more readily accessible by means of nondestructive high-resolution X-ray computed tomographic (CT) scanning, provides a window into their acoustic abilities and ecological preferences.…


Increase in parasite burden and associated pathology in harbour porpoises (Phocoena phocoena) in West Greenland

Lehnert, K.; Seibel, H.; Hasselmeier, I.; Wohlsein, P.; Iversen, M.; Nielsen, N. H.; Heide-Jørgensen, M. P.; Prenger-Berninghoff, E.; Siebert, U.
Polar Biology (2013)

Knowledge about parasitism in harbour porpoises and their health status around Greenland is scarce. This study provides knowledge about the poorly studied cetacean in its rapidly changing environment. Parasites and…
