Aquatic Mammals (2013)
Underwater impulsive sounds may affect the behavior of harbor porpoises within a certain distance from the sound source. To determine the 50% threshold received sound exposure level (SEL) of an…
Fine-scale hydrodynamics influence the spatio-temporal distribution of harbour porpoises at a coastal hotspot
Jones, A. R.; Hosegood, P.; Wynn, R. B.; De Boer, M. N.; Butler-Cowdry, S.; Embling, C. B.
Progress in Oceanography (2014)
The coastal Runnelstone Reef, off southwest Cornwall (UK), is characterised by complex topography and strong tidal flows and is a known high-density site for harbour porpoise (Phocoena phocoena); a European…
Effect of series of 1 to 2 kHz and 6 to 7 kHz up-sweeps and down-sweeps on the behavior of a harbor porpoise (Phocoena phocoena)
Kastelein, Ronald; Schop, Jessica; Gransier, Robin; Steen, Nele; Jennings, Nancy
Aquatic Mammals (2014)
To compare the effect of naval sonar up-sweeps and down-sweeps on the behavior of harbor porpoises, a harbor porpoise in a large pool was exposed to simulated low- and mid-frequency…
Beyond parasitism: Hepatic lesions in stranded harbor porpoises (Phocoena phocoena) without trematode (Campula oblonga) infections
Hiemstra, S.; Harkema, L.; Wiersma, L. C. M.; Keesler, R. I.
Veterinary Pathology (2014)
The liver can be an indicator of the health of an individual or of a group, which can be especially important to identify agents that can cause disease in multiple…

First report of infestation by a parasitic copepod (Pennella balaenopterae) in a harbour porpoise (Phocoena phocoena) from the Aegean Sea: A case report
Danyer, E.; Tonay, A. M.; Aytemiz, I.; Dede, A.; Yildirim, F.; Gurel, A.
Veterinarni Medicina (2014)
An adult, female harbour porpoise (Phocoena phocoena relicta) was found stranded on the southern Aegean Sea coast of Turkey. Thirteen holes made by copepods were observed on the lateral sides…
Determining genotypes from blowhole exhalation samples of harbour porpoises (Phocoena phocoena)
Borowska, Ewa I.; Nowak, Zuzanna; van Elk, Cornelis; Wahlberg, Magnus
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…
