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…
Reactions of captive harbor porpoises (Phocoena phocoena) to pinger-like sounds
Teilmann, Jonas; Tougaard, Jakob; Miller, Lee A.; Kirketerp, Tim; Hansen, Kirstin; Brando, Sabrina
Marine Mammal Sci (2006)
Pingers on gill nets can reduce bycatch of harbor porpoises. If harbor porpoises habituate to pingers, the effect may be reduced or lost. Two captive harbor porpoises were exposed to…
Comparison of echolocation behaviour between coastal and riverine porpoises
Akamatsu, Tomonari; Teilmann, Jonas; Miller, Lee A.; Tougaard, Jakob; Dietz, Rune; Wang, Ding; Wang, Kexiong; Siebert, Ursula; Naito, Yasuhiko
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…
Intermingling of dalli-type Dall’s porpoises into a wintering truei-type population off Japan: Implications from color patterns
Amano, Masao; Hayano, Azusa
Marine Mammal Sci (2007)
There are two major color morphs, truei and dalli types, of the Dall's porpoise and the latter includes two minor morphs. A small number of dalli types are found among…
Decrease stress; train your animals: The effect of handling methods on cortisol levels in harbour porpoises (Phocoena phocoena) under human care
Desportes, Geneviève; Buholzer, Lisette; Anderson-Hansen, Kirstin; Blanchet, Marie-Anne; Acquarone, Mario; Shephard, Gwyneth; Brando, Sabrina; Vossen, Arndt; Siebert, Ursula
Aquatic Mammals (2007)
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…
Cytokines and acute phase proteins as markers for infection in harbor porpoises (Phocoena phocoena)
Fonfara, S.; Siebert, U.; Prange, A.
Marine Mammal Sci (2007)
(...) Impairment of immune function and inflammatory incidences in marine mammals are generally difficult to detect (King et al. 1996, Zeneto-Savin et al. 1997, Funke et al. 2003). Therefore, markers…
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…
Modeling the detection range of fish by echolocating bottlenose dolphins and harbor porpoises
Au, Whitlow W. L.; Benoit-Bird, Kelly J.; Kastelein, Ronald A.
The Journal of the Acoustical Society of America (2007)
The target strength as a function of aspect angle were measured for four species of fish using dolphin-like and porpoise-like echolocation signals. The polar diagram of target strength values measured…
Prey occurrence in the stomach contents of four small cetacean species in Peru
García-Godos, I.; Van Waerebeek, K.; Reyes, J. C.; Alfaro-Shigueto, J.; Arias-Schreiber, M.
Lat. Am. J. Aquat. Mamm. (2007)
The diets of long-beaked common dolphins Delphinus capensis (n=117), dusky dolphins Lagenorhynchus obscurus (n=72), Burmeister's porpoises Phocoena spinipinnis (n=69) and offshore common bottlenose dolphins Tursiops truncatus (n=22) were determined based…
Microparasites and their potential impact on the population dynamics of small cetaceans from South America: A brief review
Van Bressem, Marie-Françoise; Raga, Juan Antonio; Barrett, Thomas; Siciliano, Salvatore; Di Beneditto, Ana Paula; Crespo, Enrique; Van Waerebeek, Koen
Scientific Committee Meeting Documents (2007)
We briefly review the pathology, epidemiology and molecular biology of cetacean viruses (including morbilli, papilloma and pox) and Brucella spp. encountered in South America. Antibodies against cetacean morbillivirus were detected…
