Information on the habitat use of the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is critical for its conservation. The diel biosonar behavior of the porpoise in the port…
Abundance and distribution of harbor porpoises and other cetaceans in the San Juan Channel: Tides and bathymetry
Hayes, K. R. R.
(2014)
The Salish Sea, an area of complex oceanography and bathymetry, supports a number of apex cetacean species. In the last decade, anomalous sightings of cetaceans have become more frequent and…
DNA barcoding for the identification of soft remains of prey in the stomach contents of grey seals (Halichoerus grypus) and harbour porpoises (Phocoena phocoena)
Méheust, Eléonore; Alfonsi, Eric; Le Ménec, Patrick; Hassani, Sami; Jung, Jean-Luc
Marine Biology Research (2014)
In recent decades, grey seals (Halichoerus grypus) and harbour porpoises (Phocoena phocoena) have become more numerous along the coasts of Brittany in northwestern France. Their interactions with fisheries are of…
Postglacial climate changes and rise of three ecotypes of harbour porpoises, Phocoena phocoena, in western Palearctic waters
Fontaine, Michaël C.; Roland, Kathleen; Calves, Isabelle; Austerlitz, Frederic; Palstra, Friso P.; Tolley, Krystal A.; Ryan, Sean; Ferreira, Marisa; Jauniaux, Thierry; Llavona, Angela; Öztürk, Bayram; Öztürk, Ayaka A.; Ridoux, Vincent; Rogan, Emer; Sequeira, Marina; Siebert, Ursula; Vikingsson, Gísli A.; Borrell, Asunción; Michaux, Johan R.; Aguilar, Alex
Molecular Ecology (2014)
Despite no obvious barriers to gene flow in the marine realm, environmental variation and ecological specializations can lead to genetic differentiation in highly mobile predators. Here, we investigated the genetic…

Sexual dimorphism and developmental patterns in the external morphology of the vaquita, Phocoena sinus
Torre, Jorge; Vidal, Omar; Brownell, Robert L.
Mar Mam Sci (2014)
A total of 56 vaquitas (Phocoena sinus) were examined to evaluate their sexual dimorphism and isometric and/or allometric growth in 35 external characteristics. Absolute and relative (to total length) measurements…
Variation in harbour porpoise activity in response to seismic survey noise
Pirotta, E.; Brookes, K. L.; Graham, I. M.; Thompson, P. M.
Biology Letters (2014)
Animals exposed to anthropogenic disturbance make trade-offs between perceived risk and the cost of leaving disturbed areas. Impact assessments tend to focus on overt behavioural responses leading to displacement, but…
Determining genotypes from blowhole exhalation samples of harbour porpoises (Phocoena phocoena)
Borowska, Ewa I.; Nowak, Zuzanna; van Elk, Cornelis; Wahlberg, Magnus
Aquatic Mammals (2014)
(...) It is currently not known if DNA could be obtained from blowhole exhalations of smaller- toothed whales, such as harbour porpoises, with much smaller exhalation volumes than bottlenose dolphins.…
Life history of harbor porpoises (Phocoena phocoena) in Scottish (UK) waters
Learmonth, Jennifer A.; Murphy, Sinead; Luque, Patricia L.; Reid, Robert J.; Patterson, I. Anthony P.; Brownlow, Andrew; Ross, Harry M.; Barley, Jason P.; Begoña Santos, M.; Pierce, Graham J.
Mar Mam Sci (2014)
Life history parameters were determined for stranded and bycaught harbor porpoises (Phocoena phocoena) from Scottish (UK) waters (1992–2005). Fetal growth rate was 84.4 mm/mo and mean size at birth was…
Direct evidence for gray seal (Halichoerus grypus) predation and scavenging on harbor porpoises (Phocoena phocoena)
Bouveroux, Thibaut; Kiszka, Jeremy J.; Heithaus, Michael R.; Jauniaux, Thierry; Pezeril, Sylvain
Mar Mam Sci (2014)
(...) gray seal (Halichoerus grypus) consumption of harbor porpoises—whether predation or scavenging—might reflect a change in gray seal feeding habits in the southern North Sea (Haelters et al. 2012), where…
