Marine Pollution Bulletin (1997)
A wide range of organochlorine residues were determined in the blubber of harbour porpoises from the Black Sea. Concentrations of DDTs (8.3–180 μg g−1 wet weight) were the highest followed…
Morphological and genetic differentiation of the Black Sea harbour porpoise Phocoena phocoena
Viaud-Martínez, K. A.; Martínez Vergara, M.; Gol'din, P. E.; Ridoux, V.; Öztürk, A. A.; Öztürk, B.; Rosel, P. E.; Frantzis, A.; Komnenou, A.; Bohonak, A. J.
Marine Ecology Progress Series (2007)
The ecological and conservation status of the geographically isolated Black Sea harbour porpoise is currently unknown. Although it has been suggested that Black Sea harbour porpoises are distinct from other…
Long-term passive acoustic monitoring revealed seasonal and diel patterns of cetacean presence in the Istanbul Strait
Dede, Ayhan; Öztürk, Ayaka Amaha; Akamatsu, Tomonari; Tonay, Arda M.; Öztürk, Bayram
Journal of the Marine Biological Association of the United Kingdom (2013)
The Istanbul Strait (Bosphorus) is a part of the Turkish Straits System, connecting the Aegean Sea and the Black Sea. There are three cetacean species in the Strait, namely the…
Contamination by butyltin compounds in harbour porpoise (Phocoena phocoena) from the Black Sea
Madhusree, Bathini; Tanabe, Shinsuke; Öztürk, Ayaka Amaha; Tatsukawa, Ryo; Miyazaki, Nobuyuki; Özdamar, Emin; Aral, Orhan; Samsun, Osman; Öztürk, Bayram
Fresenius' Journal of Analytical Chemistry (1997)
Concentrations of butyltin compounds (BTs) were determined in harbour porpoise (Phocoena phocoena) collected from the Turkish coastal waters of the Black Sea. Total butyltin compounds (∑ BTs) in the liver…
Mercury concentrations in Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis) from eastern Dongting Lake, China
Dong, Wei-Wei; Xu, Ying; Wang, Ding; Hao, Yu-Jiang;
Fresenius Environmental Bulletin (2006)
Mercury concentrations in some key tissues (liver, kidney, small intestine, stomach, blubber and brain) of five Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis), accidentally died in the Eastern Dongting Lake of…
Simulated seal scarer sounds scare porpoises, but not seals: species-specific responses to 12 kHz deterrence sounds
Mikkelsen, Lonnie; Hermannsen, Line; Beedholm, Kristian; Madsen, Peter Teglberg; Tougaard, Jakob
Royal Society Open Science (2017)
Acoustic harassment devices (AHD) or ‘seal scarers’ are used extensively, not only to deter seals from fisheries, but also as mitigation tools to deter marine mammals from potentially harmful sound…
Baltic Sea harbour porpoise populations: status and conservation needs derived from recent survey results
Benke, H.; Bräger, S.; Dähne, M.; Gallus, A.; Hansen, S.; Honnef, C. G.; Jabbusch, M.; Koblitz, J. C.; Krügel, K.; Liebschner, A.; Narberhaus, I.; Verfuß, U. K.
Marine Ecology Progress Series (2014)
During recent decades, the 2 distinct harbour porpoise populations of the Baltic Sea have decreased sharply in abundance. The Baltic Proper population is down to a few hundred individuals and…
Directional acoustic wave manipulation by a porpoise via multiphase forehead structure
Zhang, Yu; Song, Zhongchang; Wang, Xianyan; Cao, Wenwu; Au, Whitlow W. L.
Physical Review Applied (2017)
Porpoises are small-toothed whales, and they can produce directional acoustic waves to detect and track prey with high resolution and a wide field of view. Their sound-source sizes are rather…
Oceanic movements, site fidelity and deep diving in harbour porpoises from Greenland show limited similarities to animals from the North Sea
Nielsen, N. H.; Teilmann, J.; Sveegaard, S.; Hansen, R. G.; Sinding, M. H. S.; Dietz, R.; Heide-Jørgensen, M. P.
Marine Ecology Progress Series (2018)
Harbour porpoises Phocoena phocoena are common in continental shelf areas of the North Atlantic, but little information is available on their occurrence outside coastal areas. In this study, 30 harbour…
The sex life of harbor porpoises (Phocoena phocoena): Lateralized and aerial behavior
Keener, William; Webber, Marc A.; Szczepaniak, Isidore D.; Markowitz, Tim M.; Orbach, Dara N.
Aquatic Mammals (2018)
The Golden Gate Bridge in San Francisco Bay provides a non-invasive aerial platform where harbor porpoises (Phocoena phocoena) can be observed mating. We photographed 144 mating events over an eight-year…
