ZooNotes (2019)
During the last few years, the Western Black Sea coast has documented increase in the number of stranded marine mammals, particularly the harbour porpoise (Phocoena phocoena). This species is a…
Behavioral responses of harbor porpoises (Phocoena phocoena) to U.S. Navy 53C sonar signals in noise
Kastelein, Ronald A.; Ainslie, Michael A.; van Kester, Ruby
Aquatic Mammals (2019)
Naval sonar systems produce signals that may affect the behavior of harbor porpoises (Phocoena phocoena), and behavioral responses may be influenced by the received signal and by the signal-to-noise ratio…
Context-dependent biosonar adjustments during active target approaches in echolocating harbour porpoises
Ladegaard, Michael; Madsen, Peter Teglberg
The Journal of Experimental Biology (2019)
Echolocating mammals generally target individual prey items by transitioning through the biosonar phases of search (slow-rate, high-amplitude outputs), approach (gradually increasing rate and decreasing output amplitude) and buzzing (high-rate, low-amplitude…
The effects of visual impediment on the approaching behavior of harbor porpoise, Phocoena phocoena
Maezawa, Tomoki; Matsuishi, Takashi; Ito, Kiyohide; Kaji, Seiichi; Tsunokawa, Masatoshi; Kawahara, Jun I.
Mammal Study (2019)
Studies on odontocetes (e.g., porpoises) have revealed that these animals may adaptively use vision. The present study examined the contributions of vision to the approaching behavior of the harbor porpoise…
Immunohistochemical analysis of the harbor porpoise using antipodoplanin antibody PMab-237
Yamada, Shinji; Itai, Shunsuke; Nakamura, Takuro; Takei, Junko; Sano, Masato; Konnai, Satoru; Kobayashi, Atsushi; Nakagun, Shotaro; Kobayashi, Yoshiyasu; Kaneko, Mika K.; Kato, Yukinari
Monoclonal Antibodies in Immunodiagnosis and Immunotherapy (2019)
Podoplanin (PDPN)/T1 alpha is known as a specific marker of lymphatic endothelial cells and type I alveolar cells. Sensitive and specific monoclonal antibodies (mAbs) for PDPN are needed for immunohistochemical…
Quantifying harbour porpoise foraging behaviour in CPOD data: Identification, automatic detection and potential application
Berges, B. J. P.; Geelhoed, S. C. V.; Scheidat, M.; Tougaard, J.
Wageningen Marine Research Reports (2019)
Harbour porpoises (Phocoena phocoena) are regularly monitored to assess how they are impacted by the construction and operation of offshore wind farms. A suitable method to do this is passive…
Using reflected clicks to monitor range and depth of Atlantic harbour porpoises
Sanderson, B.; Adams, M.; Redden, A.
The Journal of Ocean Technology (2019)
Detection of the time of arrival of a harbour porpoise click at several synchronized broadband hydrophones, attached to a drifter, provides a method for locating porpoise and assessing any interactions…
High levels of food intake in harbor porpoises (Phocoena phocoena): Insight into recovery from disturbance
Kastelein, Ronald A.; Helder-Hoek, Lean; Booth, Cormac; Jennings, Nancy; Leopold, Mardik
Aquatic Mammals (2019)
If harbor porpoises (Phocoena phocoena) are impaired in their foraging ability because they need to move away from anthropogenic sound sources, their fitness may be reduced. Understanding how much harbor…
Drivers of the dive response in trained harbour porpoises (Phocoena phocoena)
Elmegaard, Siri L.; McDonald, Birgitte I.; Madsen, Peter T.
The Journal of Experimental Biology (2019)
Pronounced dive responses through peripheral vasoconstriction and bradycardia enable prolonged apnoea in marine mammals. For most vertebrates, the dive response is initiated upon face immersion, but little is known about…
Genetic homogeneity in the face of morphological heterogeneity in the harbor porpoise from the Black Sea and adjacent waters (Phocoena phocoena relicta)
Ben Chehida, Yacine; Thumloup, Julie; Vishnyakova, Karina; Gol’din, Pavel; Fontaine, Michael C.
Heredity (2019)
Absence of genetic differentiation is usually taken as an evidence of panmixia, but can also reflect other situations, including even nearly complete demographic independence among large-sized populations. Deciphering which situation…
