Deep Sea Research Part II: Topical Studies in Oceanography (2007)

Echolocation behaviour of a harbor porpoise and six finless porpoises was recorded in open-water systems using acoustic data loggers (A-tag). In total 1359 click trains were recorded during 4.6 h…


Decrease stress; train your animals: The effect of handling methods on cortisol levels in harbour porpoises (Phocoena phocoena) under human care

Circulating cortisol levels are accepted as a sensitive indicator of acute stress in marine mammals, particularly in relation with capture and handling. The present study provides the first long-term monitoring…


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…


Harbour porpoise (Phocoena phocoena) static acoustic monitoring: Laboratory detection thresholds of T-PODs are reflected in field sensitivity

Kyhn, Line A.; Tougaard, Jakob; Teilmann, Jonas; Wahlberg, Magnus; Jørgensen, Poul B.; Bech, Nikolaj I.
Journal of the Marine Biological Association of the United Kingdom (2008)

The T-POD (Timing POrpoise Detector) is a self-contained acoustic data logger used for detecting and monitoring the presence of echolocation clicks of small cetaceans. It has become a standard tool…
