Acoustic evidence that harbor porpoises (Phocoena phocoena) avoid bottlenose dolphins (Tursiops truncatus)
Jacobson, Eiren K.; Forney, Karin A.; Harvey, James T.
Mar Mam Sci (2014)
(...) In the present study, we investigated whether this documented conflict between bottlenose dolphins and harbor porpoises in California affected harbor porpoise behavior within the nearshore environment where habitat overlap…
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…

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…
Do man-made structures and water depth affect the diel rhythms in click recordings of harbor porpoises (Phocoena phocoena)?
Brandt, Miriam J.; Hansen, Sophie; Diederichs, Ansgar; Nehls, Georg
Mar Mam Sci (2014)
The construction of industrial offshore structures may lead to colonization by a variety of marine organisms resulting in locally enhanced biodiversity and biomass, which may then affect the habitat use…
Diet of harbor porpoises along the Dutch coast: A combined stable isotope and stomach contents approach
Jansen, Okka E.; Michel, Loïc; Lepoint, Gilles; Das, Krishna; Couperus, Abraham S.; Reijnders, Peter J. H.
Mar Mam Sci (2012)
High stranding frequency of porpoises, Phocoena phocoena, along the Dutch coast since 2006 has led to increased interest in the ecology of porpoises in the North Sea. Stranded porpoises were…
Geographic, seasonal, and diurnal surface behavior of harbor porpoises
Teilmann, Jonas; Christiansen, Casper T.; Kjellerup, Sanne; Dietz, Rune; Nachman, Gösta
Mar Mam Sci (2012)
During ship surveys harbor porpoises are only visible when breaking the sea surface to breathe, while during aerial surveys they may be seen down to 2 m below the surface.…
