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…
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…
Baseline presence of and effects of tidal turbine installation and operations on harbour porpoise in Minas Passage, Bay of Fundy, Canada
Tollit, D.; Joy, R.; Wood, J.; Redden, A.; Booth, C.; Boucher, T.; Porskamp, P.; Oldreive, M.
The Journal of Ocean Technology (2019)
Harbour porpoise echolocation activity within and outside of the FORCE tidal turbine demonstration area in Minas Passage of the upper Bay of Fundy, Nova Scotia, has been monitored by up…
Temporary hearing threshold shift in harbor porpoises (Phocoena phocoena) due to one-sixth-octave noise band at 32 kHz
Kastelein, Ronald A.; Helder-Hoek, Lean; Cornelisse, Suzanne; Huijser, Léonie A. E.; Gransier, Robin
Aquatic Mammals (2019)
Temporary hearing threshold shift (TTS) caused by fatiguing sounds in the 1.5 to 16 kHz range has been documented in harbor porpoises (Phocoena phocoena). To assess impacts of anthropogenic noise…
Testicular morphology and spermatogenesis in harbour porpoises (Phocoena phocoena)
Kesselring, T.; Viquerat, S.; IJsseldijk, L. L.; Langeheine, M.; Wohlsein, P.; Gröne, A.; Bergmann, M.; Siebert, U.; Brehm, R.
Theriogenology (2019)
Knowledge about reproductive parameters in male harbour porpoises such as testicular histology and germ cell maturation as well as seasonal changes in spermatogenesis is scarce. Thus, the aim of the…
Comparison of co-deployed drifting passive acoustic monitoring tools at a high flow tidal site: C-PODs and IcListenHF hydrophones
Adams, M.; Sanderson, B.; Porskamp, P.; Redden, A.
The Journal of Ocean Technology (2019)
Porpoise click detectors (C-PODs) and icListenHF hydrophones that record with a high sample rate were deployed on a drifter in fast tidal currents in Minas Passage, Bay of Fundy, on…
