Aquatic Mammals (2018)
Seasonal changes in food consumption, respiration rate, and body condition in a healthy captive male harbor porpoise (Phocoena phocoena) from the North Sea were recorded over 8 y. He was…
Distribution of three sympatric cetacean species off the coast of the central-western Gulf of Thailand
Jutapruet, Suwat; Intongcome, Atichat; Wang, Xianyan; Kittiwattanawong, Kongkiat; Huang, Shiang-Lin
Aquatic Mammals (2017)
Baseline data on the distribution patterns of animals disclose the dynamic function of habitat use as it relates to the accessibility of prey, social interactions, predator-prey interactions, and inter-habitat-patch mobility.…
Effects of multiple exposures to pile driving noise on harbor porpoise hearing during simulated flights—An evaluation tool
Schaffeld, Tobias; Schnitzler, Joseph G.; Ruser, Andreas; Woelfing, Benno; Baltzer, Johannes; Siebert, Ursula
The Journal of the Acoustical Society of America (2020)
Exploitation of renewable energy from offshore wind farms is substantially increasing worldwide. The majority of wind turbines are bottom mounted, causing high levels of impulsive noise during construction. To prevent…
The impact of marine vessels on the presence and behaviour of harbour porpoise (Phocoena phocoena) in the waters off Berry Head, Brixham (South West England)
Roberts, Laura; Collier, Stuart; Law, Samantha; Gaion, Andrea
Ocean & Coastal Management (2019)
Harbour porpoise (Phocoena phocoena) are protected in the UK by the Wildlife and Countryside Act (1981). Understanding the impact of anthropogenic pressures is fundamental for effective protection under this act…
Swimming features in captive odontocetes: Indicative of animals’ emotional state?
Serres, Agathe; Hao, Yujiang; Wang, Ding
Behavioural Processes (2020)
Captive welfare studies in odontocete species have been mostly conducted on bottlenose dolphins (Tursiops truncatus) while the welfare of many other species’ -including endangered species- remains poorly studied. More research…
Spatial avoidance to experimental increase of intermittent and continuous sound in two captive harbour porpoises
Kok, Annebelle C. M.; Engelberts, J. Pamela; Kastelein, Ronald A.; Helder-Hoek, Lean; Van de Voorde, Shirley; Visser, Fleur; Slabbekoorn, Hans
Environmental Pollution (2018)
The continuing rise in underwater sound levels in the oceans leads to disturbance of marine life. It is thought that one of the main impacts of sound exposure is the…
Silent porpoise: Potential sleeping behaviour identified in wild harbour porpoises
Wright, Andrew J.; Akamatsu, Tomonari; Mouritsen, Kim N.; Sveegaard, Signe; Dietz, Rune; Teilmann, Jonas
Animal Behaviour (2017)
All animals sleep and it is essential for maintaining optimal brain function. However, cetaceans engage in the unusual practice of unihemispherical sleep, where only half of their brain sleeps at…
Seasonal and diel patterns in cetacean use and foraging at a potential marine renewable energy site
Nuuttila, Hanna K.; Bertelli, Chiara M.; Mendzil, Anouska; Dearle, Nessa
Marine Pollution Bulletin (2018)
Marine renewable energy (MRE) developments often coincide with sites frequented by small cetaceans. To understand habitat use and assess potential impact from development, echolocation clicks were recorded with acoustic click…
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…
Porpoises the world over: Diversity in behavior and ecology
Teilmann, Jonas; Sveegaard, Signe
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…
