Brain, Behavior and Evolution (2016)
We compared mature dolphins with 4 other groupings of mature cetaceans. With a large data set, we found great brain diversity among 5 different taxonomic groupings. The dolphins in our…
Comparing distribution of harbour porpoises (Phocoena phocoena) derived from satellite telemetry and passive acoustic monitoring
Mikkelsen, Lonnie; Rigét, Frank F.; Kyhn, Line A.; Sveegaard, Signe; Dietz, Rune; Tougaard, Jakob; Carlström, Julia A. K.; Carlén, Ida; Koblitz, Jens C.; Teilmann, Jonas
PLOS ONE (2016)
Cetacean monitoring is essential in determining the status of a population. Different monitoring methods should reflect the real trends in abundance and patterns in distribution, and results should therefore ideally…
Fishers’ knowledge as an information source to investigate bycatch of marine mammals in the South China Sea
Liu, M.; Lin, M.; Turvey, S. T.; Li, S.
Animal Conservation (2016)
Bycatch mortality is a significant driver of marine mammal population declines. However, there is little information available on patterns or magnitude of bycatch mortality in many heavily fished Asian marine…
Comparing the performance of C-PODs and SoundTrap/PAMGUARD in detecting the acoustic activity of harbor porpoises (Phocoena phocoena)
Sarnocinska, Joanna; Tougaard, Jakob; Johnson, Mark; Madsen, Peter T.; Wahlberg, Magnus
Proceedings of Meetings on Acoustics (2016)
The C-POD logger is a widely used instrument for passive acoustic monitoring of harbor porpoises, but the absence of a continuous recording in this device makes it difficult to verify…
Asymmetry of the nasofacial skull in toothed whales (Odontoceti)
Huggenberger, S.; Leidenberger, S.; Oelschläger, H. H. A.
Journal of Zoology (2016)
In this study, the nasal asymmetry of odontocetes (toothed whales) was analyzed morphometrically by placing landmarks on photographed nasofacial skulls from 12 different species and genera that belong to four…
Mixing of porpoise ecotypes in south western UK waters revealed by genetic profiling
Fontaine, Michaël C.; Thatcher, Oliver; Ray, Nicolas; Piry, Sylvain; Brownlow, Andrew; Davison, Nicholas J.; Jepson, Paul; Deaville, Rob; Goodman, Simon J.
(2016)
Contact zones between marine ecotypes are of interest for understanding how key pelagic predators may react to climate change. We analysed the fine scale genetic structure and morphological variation in…
Comparative anatomy of the bony labyrinth of extant and extinct porpoises (Cetacea: Phocoenidae)
Racicot, Rachel A.; Gearty, William; Kohno, Naoki; Flynn, John J.
Biological Journal of the Linnean Society (2016)
The inner ear anatomy of cetaceans, now more readily accessible by means of nondestructive high-resolution X-ray computed tomographic (CT) scanning, provides a window into their acoustic abilities and ecological preferences.…
Organization and characteristics of the major histocompatibility complex class II region in the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis)
Ruan, Rui; Ruan, Jue; Wan, Xiao-Ling; Zheng, Yang; Chen, Min-Min; Zheng, Jin-Song; Wang, Ding
Scientific Reports (2016)
Little is known about the major histocompatibility complex (MHC) in the genome of Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) (YFP) or other cetaceans. In this study, a high quality YFP…
Conditioned hearing sensitivity change in the harbor porpoise (Phocoena phocoena)
Nachtigall, Paul E.; Supin, Alexander Ya.; Pacini, Aude F.; Kastelein, Ronald A.
The Journal of the Acoustical Society of America (2016)
Hearing sensitivity, during trials in which a warning sound preceding a loud sound, was investigated in two harbor porpoises (Phocoena phocoena). Sensitivity was measured using pip-train test stimuli and auditory…
Organization of the sleep-related neural systems in the brain of the harbour porpoise (Phocoena phocoena)
Dell, Leigh-Anne; Patzke, Nina; Spocter, Muhammad A.; Siegel, Jerome M.; Manger, Paul R.
Journal of Comparative Neurology (2016)
The present study provides the first systematic immunohistochemical neuroanatomical investigation of the systems involved in the control and regulation of sleep in an odontocete cetacean, the harbor porpoise (Phocoena phocoena).…
