The effect of signal duration on the underwater detection thresholds of a harbor porpoise (Phocoena phocoena) for single frequency-modulated tonal signals between 0.25 and 160 kHz

Kastelein, Ronald A.; Hoek, Lean; de Jong, Christ A. F.; Wensveen, Paul J.
The Journal of the Acoustical Society of America (2010)

The underwater hearing sensitivity of a young male harbor porpoise for tonal signals of various signal durations was quantified by using a behavioral psychophysical technique. The animal was trained to…

Interspecific variation of ontogeny and skull shape among porpoises (Phocoenidae)

Galatius, Anders; Berta, Annalisa; Frandsen, Marie Schou; Goodall, R. Natalie P.
Journal of Morphology (2010)

All extant members of Phocoenidae (porpoises) have been characterized as pedomorphic based on skeletal characters. To investigate the ontogenetic background for pedomorphosis and assess interspecific differences in ontogeny among phocoenids,…

Odontocetes of the Southern Ocean Sanctuary

Van Waerebeek, K.; Leaper, R.; Baker, A. N.; Papastavrou, V.; Thiele, D.; Findlay, K.; Donovan, G.; Ensor, P.
Journal of Cetacean Research and Management (2010)

Twenty-eight odontocete species were identified as occupying sub-Antarctic and Antarctic habitat covered by the 1994 IWC-established Southern Ocean Sanctuary. Toothed whales evidently play an important part in the Antarctic polar…

Genetic and historic evidence for climate-driven population fragmentation in a top cetacean predator: The harbour porpoises in European water

Fontaine, Michaël C.; Tolley, Krystal A.; Michaux, Johan R.; Birkun, Alexei; Ferreira, Marisa; Jauniaux, Thierry; Llavona, Ángela; Öztürk, Bayram; Öztürk, Ayaka A; Ridoux, Vincent; Rogan, Emer; Sequeira, Marina; Bouquegneau, Jean-Marie; Baird, Stuart J. E.
Proceedings of the Royal Society B: Biological Sciences (2010)

Recent climate change has triggered profound reorganization in northeast Atlantic ecosystems, with substantial impact on the distribution of marine assemblages from plankton to fishes. However, assessing the repercussions on apex…

A combined visual and acoustic estimate of 2008 abundance, and change in abundance since 1997, for the vaquita, Phocoena sinus

Gerrodette, Tim; Taylor, Barbara L.; Swift, René; Rankin, Shannon; Jaramillo-Legorreta, Armando M.; Rojas-Bracho, Lorenzo
Marine Mammal Science (2010)

A line-transect survey for the critically endangered vaquita, Phocoena sinus, was carried out in October–November 2008, in the northern Gulf of California, Mexico. Areas with deeper water were sampled visually…

Isotopic assessment of prey and habitat preferences of a cetacean community in the southwestern South Atlantic Ocean

Riccialdelli, L.; Newsome, S. D.; Fogel, M. L.; Goodall, R. N. P.
Marine Ecology Progress Series (2010)

We used stable carbon (δ13 C) and nitrogen (δ15 N) isotope analysis to investigate the trophic ecology of 8 small cetacean species of the southwestern South Atlantic Ocean: 6 delphinids…
