The population structure of the highly mobile marine mammal, the harbor porpoise (Phocoena phocoena), in the Atlantic shelf waters follows a pattern of significant isolation-by-distance. The population structure of harbor…
Polybrominated diphenyl ethers (PBDEs) and their hydroxylated and methoxylated analogues in the blood of harbor, Dall’s and finless porpoises from the Japanese coastal waters
Ochiai, Mari; Nomiyama, Kei; Isobe, Tomohiko; Yamada, Tadasu K.; Tajima, Yuko; Matsuda, Ayaka; Shiozaki, Akira; Matsuishi, Takashi; Amano, Masao; Iwata, Hisato; Tanabe, Shinsuke
Marine Environmental Research (2016)
This study investigated the accumulation of polybrominated diphenyl ethers (PBDEs) and their hydroxylated and methoxylated analogues (OH-PBDEs and MeO-PBDEs) in the blood of harbor porpoises, Dall's porpoises, and finless porpoises…
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.…
Distribution of Dall’s porpoise, Phocoenoides dalli, in the North Pacific and Bering Sea, based on T/S Oshoro Maru 2012 summer cruise data
Suzuki, Sachiko; Sekiguchi, Keiko; Mitani, Yoko; Onishi, Hiroji; Kamito, Takehiko
Zoological Science (2016)
Dall's porpoise (Phocoenoides dalli) is a small toothed cetacean, widely inhabiting the North Pacific Ocean and adjacent seas, between about 30 and 62°N; however, only limited studies of its ecology…
Habitat shapes skull profile of small cetaceans: Evidence from geographical variation in Black Sea harbour porpoises (Phocoena phocoena relicta)
Gol’din, Pavel; Vishnyakova, Karina
Zoomorphology (2016)
Morphological differentiation in skull shape in small toothed whales is sometimes explained as driven by differences in ontogeny or adaptation to a benthic or pelagic habitat. To test these hypotheses,…
Behavioral responses of a Harbor porpoise (Phocoena phocoena) to 25-kHz FM sonar signals
Kastelein, Ronald A.; van den Belt, Ivanka; Helder-Hoek, Lean; Gransier, Robin; Johansson, Torbjörn
Aquatic Mammals (2015)
The effects of three sonar sound types (peak frequency ca. 25 kHz with high-frequency side bands at 71 and 121 kHz) on the behavior of a harbor porpoise (Phocoena phocoena)…
Pingers cause temporary habitat displacement in the harbour porpoise Phocoena phocoena
Kyhn, L. A.; Jørgensen, P. B.; Carstensen, J.; Bech, N. I.; Tougaard, J.; Dabelsteen, T.; Teilmann, J.
Marine Ecology Progress Series (2015)
Several studies have shown that pingers mitigate porpoise bycatch and thus pinger use is now mandatory in some fisheries—although the long-term effects of pinger exposure on porpoises have not been…
Harbour porpoises react to low levels of high frequency vessel noise
Dyndo, Monika; Wiśniewska, Danuta Maria; Rojano-Doñate, Laia; Teglberg Madsen, Peter
Scientific Reports (2015)
Cetaceans rely critically on sound for navigation, foraging and communication and are therefore potentially affected by increasing noise levels from human activities at sea. Shipping is the main contributor of…
Range-dependent flexibility in the acoustic field of view of echolocating porpoises (Phocoena phocoena)
Wisniewska, Danuta M; Ratcliffe, John M; Beedholm, Kristian; Christensen, Christian B; Johnson, Mark; Koblitz, Jens C; Wahlberg, Magnus; Madsen, Peter T
eLife (2015)
Toothed whales use sonar to detect, locate, and track prey. They adjust emitted sound intensity, auditory sensitivity and click rate to target range, and terminate prey pursuits with high-repetition-rate, low-intensity…
Eat and be eaten – Porpoise diet studies
Leopold, Maarten Frederik
Doctoral Thesis - Wageningen University (2015)
1. Diet studies of marine mammals typically summarise prey composition across all individuals studied. Variation in individual diets is usually ignored, but may be more than just “noise” around an…
