Mar Mam Sci (2014)
(...) In the present study, we investigated whether this documented conflict between bottlenose dolphins and harbor porpoises in California affected harbor porpoise behavior within the nearshore environment where habitat overlap…
Brief behavioral response threshold levels of a harbor porpoise (Phocoena phocoena) to five helicopter dipping sonar signals (1.33 to 1.43 kHz)
Kastelein, Ronald; Gransier, Robin; van den Hoogen, Marjan; Hoek, Lean
Aquatic Mammals (2013)
Helicopter Long Range Active Sonar (HELRAS) is deployed from navy helicopters to detect submarines. Its worldwide use by NATO navies is expected to increase due to the increasing need to…
Cetacean distribution and abundance in relation to oceanographic domains on the eastern Bering Sea shelf, June and July of 2002, 2008, and 2010
Friday, Nancy A.; Zerbini, Alexandre N.; Waite, Janice M.; Moore, Sue E.; Clapham, Phillip J.
Deep Sea Research Part II: Topical Studies in Oceanography (2013)
As part of the Bering Sea Project, cetacean surveys were conducted to describe distribution and estimate abundance on the eastern Bering Sea shelf. Three marine mammal observers conducted visual surveys…
Morphology and variation in porpoise (Cetacea: Phocoenidae) cranial endocasts
Racicot, Rachel A.; Colbert, Matthew W.
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…
Long-term passive acoustic monitoring revealed seasonal and diel patterns of cetacean presence in the Istanbul Strait
Dede, Ayhan; Öztürk, Ayaka Amaha; Akamatsu, Tomonari; Tonay, Arda M.; Öztürk, Bayram
Journal of the Marine Biological Association of the United Kingdom (2013)
The Istanbul Strait (Bosphorus) is a part of the Turkish Straits System, connecting the Aegean Sea and the Black Sea. There are three cetacean species in the Strait, namely the…
Records of harbour porpoises (Phocoena phocoena) in fishing nets during the interwar period in Poland: Verification of archival materials
Psuty, Iwona
Aquatic Mammals (2013)
The Polish fisheries administration registered incidents of harbour porpoises caught by fishermen from fishing bases within the country's borders between 1922 and 1938. These data are unique in the Baltic…
Sexual dimorphism of Dall’s porpoise and harbor porpoise skulls
Frandsen, Marie Schou; Galatius, Anders
Mammalian Biology - Zeitschrift für Säugetierkunde (2013)
To evaluate and quantify sexual dimorphism of skull shape and assess the ontogenetic background for differences, samples of 134 harbor porpoise (Phocoena phocoena) and 85 Dall's porpoise (Phocoenoides dalli) were…
Identifying foraging behaviour of wild bottlenose dolphins (Tursiops truncatus) and harbour porpoises (Phocoena phocoena) with static acoustic dataloggers
Nuuttila, H. K.; Meier, R.; Evans, P. G. H.; Turner, J. R.; Bennell, J. D.; Hiddink, J. G.
Aquatic Mammals (2013)
Sound is the main means of communication for cetaceans, and studying their vocal behaviour can reveal important information about their activity patterns. As static acoustic monitoring (SAM) of whales, dolphins,…
Increase in parasite burden and associated pathology in harbour porpoises (Phocoena phocoena) in West Greenland
Lehnert, K.; Seibel, H.; Hasselmeier, I.; Wohlsein, P.; Iversen, M.; Nielsen, N. H.; Heide-Jørgensen, M. P.; Prenger-Berninghoff, E.; Siebert, U.
Polar Biology (2013)
Knowledge about parasitism in harbour porpoises and their health status around Greenland is scarce. This study provides knowledge about the poorly studied cetacean in its rapidly changing environment. Parasites and…
Accumulation of hydroxylated polychlorinated biphenyls (OH-PCBs) and implications for PCBs metabolic capacities in three porpoise species
Ochiai, Mari; Nomiyama, Kei; Isobe, Tomohiko; Mizukawa, Hazuki; Yamada, Tadasu K.; Tajima, Yuko; Matsuishi, Takashi; Amano, Masao; Tanabe, Shinsuke
Chemosphere (2013)
The present study investigated polychlorinated biphenyls (PCBs) and hydroxylated metabolites of PCBs (OH-PCBs) in blood from three porpoise species: finless porpoises (Neophocaena phocaenoides), harbor porpoises (Phocoena phocoena), and Dall’s porpoises…
