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…
Forensic microbiology reveals that Neisseria animaloris infections in harbour porpoises follow traumatic injuries by grey seals
Foster, Geoffrey; Whatmore, Adrian M.; Dagleish, Mark P.; Malnick, Henry; Gilbert, Maarten J.; Begeman, Lineke; Macgregor, Shaheed K.; Davison, Nicholas J.; Roest, Hendrik Jan; Jepson, Paul; Howie, Fiona; Muchowski, Jakub; Brownlow, Andrew C.; Wagenaar, Jaap A.; Kik, Marja J. L.; Deaville, Rob; ten Doeschate, Mariel T. I.; Barley, Jason; Hunter, Laura; IJsseldijk, Lonneke L.
Scientific Reports (2019)
Neisseria animaloris is considered to be a commensal of the canine and feline oral cavities. It is able to cause systemic infections in animals as well as humans, usually after…
Time and tide: Seasonal, diel and tidal rhythms in Wadden Sea harbour porpoises (Phocoena phocoena)
Zein, Beate; Woelfing, Benno; Dähne, Michael; Schaffeld, Tobias; Ludwig, Stefan; Rye, Jacob Hansen; Baltzer, Johannes; Ruser, Andreas; Siebert, Ursula
PLOS ONE (2019)
Odontocetes have evolved a rich diversity of prey- and habitat-specific foraging strategies, which allows them to feed opportunistically on locally and temporally abundant prey. While habitat-specific foraging strategies have been…
Salmonid passive integrated transponder tags and coded wire tags found in the forestomach of a harbor porpoise (Phocoena phocoena) in southwestern Washington
D’Alessandro, Dalin N.; Duffield, Deborah A.
Fishery Bulletin (2019)
A dead adult harbor porpoise (Phocoena phocoena) was found on the Long Beach Peninsula in Washington on 22 August 2012. The harbor porpoise was skeletonized, with the forestomach being the…
Records of harbour porpoise (Phocoena phocoena) in the mouth of the Douro River (northern Portugal) with presence of an anomalous white individual
Gil, Ágatha; Correia, Ana M.; Sousa-Pinto, Isabel
Marine Biodiversity Records (2019)
Harbour porpoise (Phocoena phocoena) is listed under the Annex II of the European Habitats Directive (Directive 92/43/CEE) and Member States are required to designate special areas of conservation to protect…
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…
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…
