The Anatomical Record (2013)
Evolution of endocranial anatomy in cetaceans is important from the perspective of echolocation ability, intelligence, social structure, and alternate pathways for circulation to the brain. Apart from the importance of…
Brief behavioral response threshold level of a harbor porpoise (Phocoena phocoena) to an impulsive sound
Kastelein, Ronald; Steen, Nele; Gransier, Robin; de Jong, Christ A. F.
Aquatic Mammals (2013)
Underwater impulsive sounds may affect the behavior of harbor porpoises within a certain distance from the sound source. To determine the 50% threshold received sound exposure level (SEL) of an…
Preliminary study on genetic differences between two species of finless porpoises, genus Neophocaena, with lack of genetic divergence between two subspecies of the narrow-ridged finless porpoise, N. asiaeorientalis: cytochrome b sequence analyses
Koh, H. S.; Jo, J. E.; Ahn, N. H.; Lee, J. H.; Kim, K. S.; Jin, C. W.
Journal of Cetacean Research and Management (2013)
Using samples from bycaught finless porpoises, cytochrome b sequences were analysed and phylogenetic trees were constructed. The aims were to: (1) determine genetic divergences within the genus Neophocaena; (2) examine…
Beyond parasitism: Hepatic lesions in stranded harbor porpoises (Phocoena phocoena) without trematode (Campula oblonga) infections
Hiemstra, S.; Harkema, L.; Wiersma, L. C. M.; Keesler, R. I.
Veterinary Pathology (2014)
The liver can be an indicator of the health of an individual or of a group, which can be especially important to identify agents that can cause disease in multiple…
Unique feeding morphology in a new Prognathous extinct porpoise from the Pliocene of California
Racicot, Rachel A.; Deméré, Thomas A.; Beatty, Brian L.; Boessenecker, Robert W.
Current Biology (2014)
Modern porpoises (Odontoceti: Phocoenidae) are some of the smallest cetaceans and usually feed near the seafloor on small fish and cephalopods [1, 2 and 3]. Within both extinct and extant…
Studying the biosonar of bats and porpoises using multi receiver arrays
Koblitz, Jens C.
Doctoral Thesis - Eberhard Karls Universität Tübingen (2014)
Echolocation, the main sensory modality of odontocetes and microbats, has mostly been studied using single receivers. Such a recording setup is sufficient to study signal parameters like pulse interval, inter…
Effect of series of 1 to 2 kHz and 6 to 7 kHz up-sweeps and down-sweeps on the behavior of a harbor porpoise (Phocoena phocoena)
Kastelein, Ronald; Schop, Jessica; Gransier, Robin; Steen, Nele; Jennings, Nancy
Aquatic Mammals (2014)
To compare the effect of naval sonar up-sweeps and down-sweeps on the behavior of harbor porpoises, a harbor porpoise in a large pool was exposed to simulated low- and mid-frequency…

Equal latency contours and auditory weighting functions for the harbour porpoise (Phocoena phocoena)
Wensveen, P. J.; Huijser, L. A. E.; Hoek, L.; Kastelein, R. A.
Journal of Experimental Biology (2014)
Loudness perception by human infants and animals can be studied under the assumption that sounds of equal loudness elicit equal reaction times (RTs). Simple RTs of a harbour porpoise to…
Abundance and distribution of harbor porpoises and other cetaceans in the San Juan Channel: Tides and bathymetry
Hayes, K. R. R.
(2014)
The Salish Sea, an area of complex oceanography and bathymetry, supports a number of apex cetacean species. In the last decade, anomalous sightings of cetaceans have become more frequent and…
