Distribution, abundance, habitat use, and respiration patterns of harbor porpoise (Phocoena phocoena) off the northern San Juan Islands, Washington
Raum-Suryan, K. L.
Master's Thesis - San Jose State University (1995)
Boat and shore-based surveys were conducted from June to August 1991 and June to October 1992 to determine harbor porpoise distribution, density, abundance, and habitat use off the northern San…
Cognitive control of heart rate in diving harbor porpoises
Elmegaard, Siri L.; Johnson, Mark; Madsen, Peter T.; McDonald, Birgitte I.
Current Biology (2016)
Marine mammals have adapted to forage while holding their breath in a suite of aquatic habitats from shallow rivers to deep oceans. The key to tolerate such extensive apnea is…
External morphology of Dall’s porpoise (Phocoenoides dalli): Growth and sexual dimorphism
Amano, Masao; Miyazaki, Nobuyuki
Canadian Journal of Zoology (1993)
We studied development and sexual dimorphism in external measurements of Dall's porpoises (Phocoenoides dalli) from the northwestern North Pacific. Relative rates of increase in the measurements of the head and…
Silent porpoise: Potential sleeping behaviour identified in wild harbour porpoises
Wright, Andrew J.; Akamatsu, Tomonari; Mouritsen, Kim N.; Sveegaard, Signe; Dietz, Rune; Teilmann, Jonas
Animal Behaviour (2017)
All animals sleep and it is essential for maintaining optimal brain function. However, cetaceans engage in the unusual practice of unihemispherical sleep, where only half of their brain sleeps at…
Environmental drivers of harbour porpoise fine-scale movements
van Beest, Floris M.; Teilmann, Jonas; Dietz, Rune; Galatius, Anders; Mikkelsen, Lonnie; Stalder, Dominique; Sveegaard, Signe; Nabe-Nielsen, Jacob
Marine Biology (2018)
Quantifying intraspecific variation in movement behaviour of marine predators and the underlying environmental drivers is important to inform conservation management of protected species. Here, we provide the first empirical data…
Dive heart rate in harbour porpoises is influenced by exercise and expectations
McDonald, Birgitte I.; Johnson, Mark; Madsen, Peter T.
The Journal of Experimental Biology (2017)
The dive response, a decrease in heart rate (fH) and peripheral vasoconstriction, is the key mechanism allowing breath-hold divers to perform long-duration dives. This pronounced cardiovascular response to diving has…
