Poyang Lake is the largest freshwater lake in China and flows into the Yangtze River. It is a traditional habitat for the endangered Yangtze finless porpoise, which has not been…
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…
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…
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…
Bilateral directional asymmetry of the appendicular skeleton of the harbor porpoise (Phocoena phocoena)
Galatius, Anders; Jespersen, Ase
Marine Mammal Sci (2005)
Directional asymmetry (DA) of the lengths, diameters, and masses of the scapula, humerus, radius, and ulna were analyzed on a sample of 213 harbor porpoises from Denmark and West Greenland.…
Co-variation in the probabilities of sighting harbor porpoises and bottlenose dolphins
Thompson, Paul; White, Sam; Dickson, Ellie
Marine Mammal Sci (2004)
(...) In this study we used data collected from commercial dolphin-watching trips to determine whether there was any relationship between the probabilities of sighting bottlenose dolphins and harbor porpoises. Surveys…
Variability in the diet of harbor porpoises (Phocoena phocoena) in Scottish waters 1992–2003
Santos, M. B.; Pierce, G. J.; Learmonth, J. A.; Reid, R. J.; Ross, H. M.; Patterson, I. A. P.; Reid, D. G.; Beare, D.
Marine Mammal Sci (2004)
Interannual, seasonal, and regional variation in the diet of porpoises, Phocoena phocoena, in Scottish (UK) waters was studied using stomach contents of animals stranded between 1992 and 2003. Most samples…
Diet of harbor porpoises in the Kattegat and Skagerrak seas: Accounting for individual variation and sample size
Borjesson, Patrik; Berggren, Per; Ganning, Bjorn
Marine Mammal Sci (2003)
Stomach contents of 112 bycaught harbor porpoises (Phocoena phocoena) collected between 1989 and 1996 in the Kattegat and Skagerrak seas were analyzed to describe diet composition and estimate prey size,…
Effect of the sound generated by an acoustic harassment device on the relative abundance and distribution of harbor porpoises (Phocoena phocoena) in Retreat Passage, British Columbia
Olesiuk, Peter F.; Nichol, Linda M.; Sowden, Margaret J.; Ford, John K. B.
Marine Mammal Sci (2002)
We describe an experiment conducted to assess the impact of the sound generated by an acoustic harassment device (AHD) on the relative abundance and distribution of harbor porpoises (Phocoena phocoena)…
Skin density and its influence on buoyancy in the manatee (Trichechus manatus latirostris), harbor porpoise (Phocoena phocoena), and bottlenose dolphin (Tursiops truncatus)
Kipps, E. K.; Mclellan, W. A.; Rommel, S. A.; Pabst, D. A.
Marine Mammal Sci (2002)
This study investigated how skin contributes to buoyancy control in the Florida manatee (Trichechus manatus latirostris), harbor porpoise (Phocoena phocoena), and bottlenose dolphin (Tursiops truncatus). Manatees are shallow divers and…
