For the period 2008-2017, finds of stranded cetaceans along the Danish coastline are listed and reviewed in comparison to the preceding 40-year period (1968-2007). The harbour porpoise (Phocoena phocoena) was…
High rates of vessel noise disrupt foraging in wild harbour porpoises (Phocoena phocoena)
Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Siebert, Ursula; Galatius, Anders; Dietz, Rune; Madsen, Peter Teglberg
Proceedings of the Royal Society B: Biological Sciences (2018)
Shipping is the dominant marine anthropogenic noise source in the world's oceans, yet we know little about vessel encounter rates, exposure levels and behavioural reactions for cetaceans in the wild,…
Histological variation in blubber morphology of the endangered East Asian finless porpoise (Neophocaena asiaeorientalis sunameri) with ontogeny and reproductive states
Ji, Junhua; Nabi, Ghulam; Zeng, Xianyuan; Hao, Yujiang; Wang, Ding
Zoological Studies (2019)
The highly lipid-rich blubber in the hypodermis is a specialized structure that functions in thermoregulation, energy storage, buoyancy control, locomotion, and streamlining the body shape in marine mammals. The key…
Physical modeling and validation of porpoises’ directional emission via hybrid metamaterials
Dong, Erqian; Zhang, Yu; Song, Zhongchang; Zhang, Tianye; Cai, Chen; Fang, Nicholas X.
National Science Review (2019)
In wave physics and engineering, directional emission sets a fundamental limitation on conventional simple sources as their sizes should be sufficiently larger than their wavelength. Artificial metamaterial and animal biosonar…

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…
Abundance and seasonality of Dall’s porpoise (Phocoenoides dalli) in southeast Alaska
Jefferson, T. A.; Dahlheim, M. E.; Zerbini, A. N.; Waite, J. M.; Kennedy, A. S.
NOAA Technical Memorandum NMFS-AFSC-385 (2019)
Little is known about Dall’s porpoise (Phocoenoides dalli) population biology in Southeast Alaska. Here we present the first abundance estimates for Dall’s porpoise in the waters of Southeast Alaska. We…

We are among the scientists who have documented the environmental and ecological changes to the Upper Gulf of California following the reduction in the Colorado River’s flow. We object to…
Clinical, pathological, and laboratory diagnoses of diseases of harbour porpoises (Phocoena phocoena), live stranded on the Dutch and adjacent coasts from 2003 to 2016
van Elk, Cornelis E.; van de Bildt, Marco W. G.; van Run, Peter R. W. A.; Bunskoek, Paulien; Meerbeek, Jolanda; Foster, Geoffrey; Osterhaus, Albert D. M. E.; Kuiken, Thijs
Veterinary Research (2019)
Harbour porpoises (Phocoena phocoena) in the North Sea live in an environment heavily impacted by humans, the consequences of which are a concern for their health. Autopsies carried out on…
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…
