Ethology and Behavioral Ecology of Odontocetes (2019)
Unlike the large number of species of true dolphins, there are only seven porpoise or phocoenid species, inhabiting different habitats and climate zones. They range from ice-covered water in the…
Porpoise click classifier (PorCC): A high-accuracy classifier to study harbour porpoises (Phocoena phocoena) in the wild
Cosentino, Mel; Guarato, Francesco; Tougaard, Jakob; Nairn, David; Jackson, Joseph C.; Windmill, James F. C.
The Journal of the Acoustical Society of America (2019)
Harbour porpoises are well-suited for passive acoustic monitoring (PAM) as they produce highly stereotyped narrow-band high-frequency (NBHF) echolocation clicks. PAM systems must be coupled with a classification algorithm to identify…
Characterization of a novel rhabdovirus isolated from a stranded harbour porpoise (Phocoena phocoena)
Emelianchik, Alexandra; Rodrigues, Thaís C. S.; Subramaniam, Kuttichantran; Nielsen, Ole; Burek-Huntington, Kathy A.; Rotstein, David; Popov, Vsevolod L.; Stone, David; Waltzek, Thomas B.
Virus Research (2019)
An adult male harbour porpoise (Phocoena phocoena) stranded off the coast of Alaska displaying poor body condition, scattered mild ulcerative dermatitis, and necrotizing balanoposthitis. Necropsy findings included severe verminous panniculitis,…
Food for thought: Harbor porpoise foraging behavior and diet inform vulnerability to disturbance
Booth, Cormac G.
Marine Mammal Science (2019)
Research has shown that noise disturbance can disrupt the behavior of harbor porpoises. The significance of such disturbance is unclear. However, these animals may be vulnerable to starvation when disturbed…
Time of arrival difference estimation for narrow band high frequency echolocation clicks
Gillespie, Douglas; Macaulay, Jamie
The Journal of the Acoustical Society of America (2019)
Algorithms are presented for the accurate time of arrival difference estimation of high frequency narrow band echolocation clicks from Harbor Porpoise. These clicks typically have a center frequency of around…
Unexpected mid‐winter presence of harbor porpoises (Phocoena phocoena) in Kotzebue Sound, Alaska
Whiting, Alex; Castellote, Manuel; Small, Robert J.; Frost, Kathryn J.; Suydam, Robert
Marine Mammal Science (2019)
...Harbor porpoises have been reported as an uncommon species in Kotzebue Sound during the ice-free months of June through October (Frost & Lowry, 1990), but their presence in Kotzebue Sound…
The use of seal scarers as a protective mitigation measure can induce hearing impairment in harbour porpoises
Schaffeld, Tobias; Ruser, Andreas; Woelfing, Benno; Baltzer, Johannes; Kristensen, Jakob H.; Larsson, Josefin; Schnitzler, Joseph G.; Siebert, Ursula
The Journal of the Acoustical Society of America (2019)
Acoustic deterrent devices (ADDs) are used to deter seals from aquacultures but exposure of harbour porpoises (Phocoena phocoena) occurs as a side-effect. At construction sites, by contrast, ADDs are used…
Mycotic infections in free-ranging harbor porpoises (Phocoena phocoena)
Kapetanou, Athanasia; IJsseldijk, Lonneke L.; Willems, Dorien S.; Broens, Els M.; Everaarts, Eligius; Buil, Jochem B.; Verweij, Paul E.; Kik, Marja J. L.; Gröne, Andrea
Frontiers in Marine Science (2020)
Studies on the occurrence of fungal communities in the marine environment are still scarce, but mycotic infections in cetaceans are increasingly reported. Fungal disease following infection with Aspergillus species is…
Modelling fine-scale distribution and relative abundance of harbour porpoises in the Southern Bight of the North Sea using platform-of-opportunity data
Bouveroux, Thibaut; Waggitt, James J.; Belhadjer, Anissa; Cazenave, Pierre W.; Evans, Peter G.H.; Kiszka, Jeremy J.
Journal of the Marine Biological Association of the United Kingdom (2020)
Over the last 25 years, the harbour porpoise (Phocoena phocoena) has made a significant return to the Southern Bight of the North Sea and the English Channel due to a…
Distribution and abundance of cetaceans in Icelandic waters over 30 years of aerial surveys
Pike, Daniel; Gunnlaugsson, Thorvaldur; Sigurjonsson, Johann; Vikingsson, Gisli
NAMMCO Scientific Publications (2020)
Beginning in 1986, 7 aerial surveys covering the coastal waters of Iceland have been conducted up to 2016. In addition, several partial surveys covering portions of the same area and…
