Aquatic Mammals (2014)
(...) It is currently not known if DNA could be obtained from blowhole exhalations of smaller- toothed whales, such as harbour porpoises, with much smaller exhalation volumes than bottlenose dolphins.…
Variation in harbour porpoise activity in response to seismic survey noise
Pirotta, E.; Brookes, K. L.; Graham, I. M.; Thompson, P. M.
Biology Letters (2014)
Animals exposed to anthropogenic disturbance make trade-offs between perceived risk and the cost of leaving disturbed areas. Impact assessments tend to focus on overt behavioural responses leading to displacement, but…
Studying the biosonar of bats and porpoises using multi receiver arrays
Koblitz, Jens C.
Doctoral Thesis - Eberhard Karls Universität Tübingen (2014)
Echolocation, the main sensory modality of odontocetes and microbats, has mostly been studied using single receivers. Such a recording setup is sufficient to study signal parameters like pulse interval, inter…
High frequency components of ship noise in shallow water with a discussion of implications for harbor porpoises (Phocoena phocoena)
Hermannsen, Line; Beedholm, Kristian; Tougaard, Jakob; Madsen, Peter T.
The Journal of the Acoustical Society of America (2014)
Growing ship traffic worldwide has led to increased vessel noise with possible negative impacts on marine life. Most research has focused on low frequency components of ship noise, but for…
Postglacial climate changes and rise of three ecotypes of harbour porpoises, Phocoena phocoena, in western Palearctic waters
Fontaine, Michaël C.; Roland, Kathleen; Calves, Isabelle; Austerlitz, Frederic; Palstra, Friso P.; Tolley, Krystal A.; Ryan, Sean; Ferreira, Marisa; Jauniaux, Thierry; Llavona, Angela; Öztürk, Bayram; Öztürk, Ayaka A.; Ridoux, Vincent; Rogan, Emer; Sequeira, Marina; Siebert, Ursula; Vikingsson, Gísli A.; Borrell, Asunción; Michaux, Johan R.; Aguilar, Alex
Molecular Ecology (2014)
Despite no obvious barriers to gene flow in the marine realm, environmental variation and ecological specializations can lead to genetic differentiation in highly mobile predators. Here, we investigated the genetic…
Equal latency contours and auditory weighting functions for the harbour porpoise (Phocoena phocoena)
Wensveen, P. J.; Huijser, L. A. E.; Hoek, L.; Kastelein, R. A.
Journal of Experimental Biology (2014)
Loudness perception by human infants and animals can be studied under the assumption that sounds of equal loudness elicit equal reaction times (RTs). Simple RTs of a harbour porpoise to…
Population structure and intergeneric hybridization in harbour porpoises Phocoena phocoena in British Columbia, Canada
Crossman, CA; Barrett-Lennard, LG; Taylor, EB
Endangered Species Research (2014)
We used variation at microsatellite loci and in mitochondrial DNA (mtDNA) to detect and quantify (1) hybridization between the harbour porpoises Phocoena phocoena and the Dall’s porpoises Phoconoides dalli and…
Do larger tag packages alter diving behavior in harbor porpoises?

Effects of noise and by-catch on a Danish harbour porpoise population
Nabe-Nielsen, Jacob; Sibly, Richard M.; Tougaard, Jakob; Teilmann, Jonas; Sveegaard, Signe
Ecological Modelling (2014)
Ships and wind turbines generate noise, which can have a negative impact on marine mammal populations by scaring animals away. Effective modelling of how this affects the populations has to…
DNA barcoding for the identification of soft remains of prey in the stomach contents of grey seals (Halichoerus grypus) and harbour porpoises (Phocoena phocoena)
Méheust, Eléonore; Alfonsi, Eric; Le Ménec, Patrick; Hassani, Sami; Jung, Jean-Luc
Marine Biology Research (2014)
In recent decades, grey seals (Halichoerus grypus) and harbour porpoises (Phocoena phocoena) have become more numerous along the coasts of Brittany in northwestern France. Their interactions with fisheries are of…
