Anthropogenic effects have created various risks for wild animals. Boat traffic is one of the most fatal risks for marine mammals. Individual behavioral responses of cetaceans, including diving behavior such…
Prey of killer whales (Orcinus orca) in Iceland
Samarra, Filipa I. P.; Bassoi, Manuela; Béesau, Julie; Elíasdóttir, Margrét Ó.; Gunnarsson, Karl; Mrusczok, Marie-Thérèse; Rasmussen, Marianne; Rempel, Jonathan N.; Thorvaldsson, Baldur; Víkingsson, Gísli A.
PLOS ONE (2018)
Killer whales have a cosmopolitan distribution and as a species are generalists, feeding on a variety of prey. However, local populations tend to specialise on specific prey types. In Icelandic…
Coming of age: Do female harbour porpoises (Phocoena phocoena) from the North Sea and Baltic Sea have sufficient time to reproduce in a human influenced environment?
Kesselring, Tina; Viquerat, Sacha; Brehm, Ralph; Siebert, Ursula
PLOS ONE (2017)
The harbour porpoise is the only cetacean species native to German waters. Since human pressures are suggested to shorten their reproductive lifespan, basic knowledge on reproduction is strongly required. One…
The source parameters of echolocation clicks from captive and free-ranging Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)
Fang, Liang; Wang, Ding; Li, Yongtao; Cheng, Zhaolong; Pine, Matthew K.; Wang, Kexiong; Li, Songhai
PLOS ONE (2015)
The clicks of Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) from 7 individuals in the tank of Baiji aquarium, 2 individuals in a netted pen at Shishou Tian-e-zhou Reserve and 4…
Drivers of the dive response in trained harbour porpoises (Phocoena phocoena)
Elmegaard, Siri L.; McDonald, Birgitte I.; Madsen, Peter T.
The Journal of Experimental Biology (2019)
Pronounced dive responses through peripheral vasoconstriction and bradycardia enable prolonged apnoea in marine mammals. For most vertebrates, the dive response is initiated upon face immersion, but little is known about…
Context-dependent biosonar adjustments during active target approaches in echolocating harbour porpoises
Ladegaard, Michael; Madsen, Peter Teglberg
The Journal of Experimental Biology (2019)
Echolocating mammals generally target individual prey items by transitioning through the biosonar phases of search (slow-rate, high-amplitude outputs), approach (gradually increasing rate and decreasing output amplitude) and buzzing (high-rate, low-amplitude…
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…

Proceedings of the United States National Museum (1927)
Among the spirit specimens of mammals in the United States National Museum are several of the Chinese black finless porpoise, Neomeris phocaenoides (Cuvier), which were presented to the Museum by…

Porpoise. The Porpoise [Phocaena communis, or P. phocaena) is the smallest and most common of the Cetaceans found in the seas around the British Isles, and it also frequents the…
The morphology and geographic distribution of epidermal diatoms of the Dall’s porpoise (Phocoenoides dalli True) in the northern Pacific Ocean
Holmes, R. W.; Nagasawa, S.; Takano, H.
Bulletin of the National Science Museum, Tokyo, Series B (1993)
The morphology of diatoms which consistently occur in circular to oval colonies on the skin of North Pacific Dall's porpoise was examined. Two previously described cetacean diatoms Stauroneis aleutica Nemoto…
