Conservation Biology (2007)
The recent likely extinction of the baiji (Chinese river dolphin [Lipotes vexillifer]) (Turvey et al. 2007) makes the vaquita (Gulf of California porpoise [Phocoena sinus]) the most endangered cetacean. The…

Tonay, A. M.; Dede, A.; Öztürk, A. A.
Rapports et Procès-Verbaux des Réunions de la Commission Internationale pour l'Exploration Scientifique de la Mer Méditerranée (2007)
The study was based on stomach content of four harbour porpoises bycaught in the coastal fishery in 2004 and 2006, on the Marmara Sea coast. Three fish species, horse mackerel…
Increased blood interleukin-10 mRNA levels in diseased free-ranging harbor porpoises (Phocoena phocoena)
Beineke, Andreas; Siebert, Ursula; Müller, Gundi; Baumgärtner, Wolfgang
Veterinary Immunology and Immunopathology (2007)
Harbor porpoises from the North and Baltic Seas exhibit a higher incidence of bacterial infections compared to whales from less polluted arctic waters. Toxicological analysis revealed an association between elevated…
Genetic drift vs. natural selection in a long-term small isolated population: major histocompatibility complex class II variation in the Gulf of California endemic porpoise (Phocoena sinus)
MUNGUIA-VEGA, ADRIAN; ESQUER-GARRIGOS, YARELI; ROJAS-BRACHO, LORENZO; VAZQUEZ-JUAREZ, RICARDO; CASTRO-PRIETO, AINES; FLORES-RAMIREZ, SERGIO
Molecular Ecology (2007)
Although many studies confirm long-term small isolated populations (e.g. island endemics) commonly sustain low neutral genetic variation as a result of genetic drift, it is less clear how selection on…
Reduction of harbour porpoise (Phocoena phocoena) bycatch by iron-oxide gillnets
Larsen, F.; Ritzau Eigaard, O.; Tougaard, J.
Fisheries Research (2007)
Reduction of harbour porpoise bycatch by use of high-density iron-oxide (IO) gillnets was tested in sea trials in the Danish North Sea bottom set gillnet fishery in September–October 2000. The…

We succinctly review and document new cases of diseases of the skin and the skeletal system and external traumata in cetaceans from Ecuador, Colombia, Peru, Chile, Argentina, Uruguay, Brazil, and…
Predation by killer whales (Orcinus orca) and the evolution of whistle loss and narrow-band high frequency clicks in odontocetes
Morisaka, T.; Connor, R. C.
Journal of Evolutionary Biology (2007)
A disparate selection of toothed whales (Odontoceti) share striking features of their acoustic repertoires including the absence of whistles and high frequency but weak (low peak-to-peak source level) clicks that…
Mate guarding in male Dall’s porpoises (Phocoenoides dalli)
Willis, Pamela M.; Dill, Lawrence M.
Ethology (2007)
Mate guarding, whereby a male closely attends and defends a fertile female from extra-pair matings, is one mating tactic males of many species use to protect their paternity. Although female…
Stomach content of harbour porpoises (Phocoena phocoena) from the Turkish western Black Sea in spring and early summer
Tonay, A. M.; Dede, A.; Öztürk, A. A.; Öztürk, B.
Rapports et Procès-Verbaux des Réunions de la Commission Internationale pour l'Exploration Scientifique de la Mer Méditerranée (2007)
The study was based on stomach content from 42 harbour porpoises bycaught or stranded between April to June in 2002 and 2003, on the Turkish western Black Sea coast. Seven…
Perception of low-frequency acoustic signals by a harbour porpoise (Phocoena phocoena) in the presence of simulated offshore wind turbine noise
Lucke, Klaus; Lepper, Paul A.; Hoeve, Bert; Everaarts, Eligius; van Elk, Niels; Siebert, Ursula
Aquatic Mammals (2007)
Using auditory evoked potential (AEP) methods, a study was conducted on a harbour porpoise (Phocoena phocoena) at the Dolfinarium Harderwijk in The Netherlands. The study measured the audible range of…
