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…


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…


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…

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…


Timing of epiphyseal development in the flipper skeleton of the harbour porpoise (Phocoena phocoena) as an indicator of paedomorphosis

Galatius, Anders; Andersen, Mai-Britt Elin Rindom; Haugan, Birgitte; Langhoff, Heidi Elisabeth; Jespersen, Åse
Acta Zoologica (2006)

Epiphyseal development was investigated on X-rays of flippers from 158 harbour porpoises from Danish waters. Development followed a proximodistal pattern similar to what is known in other cetacean species. Ossification…


Where is the risk? Integrating a spatial distribution model and a risk assessment to identify areas of cetacean interaction with fisheries in the northeast Atlantic

Breen, Patricia; Brown, Susie; Reid, David; Rogan, Emer
Ocean & Coastal Management (2017)

Throughout their range, marine mammals are vulnerable to incidental capture in fishing gear. Bycatch is a particularly important issue for cetaceans, which generally have lower potential rates of population growth…
