Aquatic Mammals (2016)
The dorsal fin of odontocetes has, among other roles, hydrodynamic and thermoregulatory functions. In captivity, the dorsal fin sometimes bends laterally. Bending of the dorsal fin was described in 13…
Identification of high-risk areas for harbour porpoise Phocoena phocoena bycatch using remote electronic monitoring and satellite telemetry data
Kindt-Larsen, L.; Berg, C. W.; Tougaard, J.; Sørensen, T. K.; Geitner, K.; Northridge, S.; Sveegaard, S.; Larsen, F.
Marine Ecology Progress Series (2016)
The bycatch of harbour porpoise Phocoena phocoena is an issue of major concern for fisheries management and for porpoise conservation. We used high-resolution spatial and temporal data on porpoise abundance…
Harbor porpoise (Phocoena phocoena) recovery in the inland waters of Washington: Estimates of density and abundance from aerial surveys, 2013–2015
Jefferson, Thomas A.; Smultea, Mari A.; Courbis, Sarah S.; Campbell, Gregory S.
Canadian Journal of Zoology (2016)
The harbor porpoise (Phocoena phocoena (L., 1758)) used to be common in Puget Sound, Washington, but virtually disappeared from these waters by the 1970s. We conducted systematic aerial line-transect surveys…
Inter-species differences in polychlorinated biphenyls patterns from five sympatric species of odontocetes: Can PCBs be used as tracers of feeding ecology?
Méndez-Fernandez, Paula; Simon-Bouhet, Benoit; Bustamante, Paco; Chouvelon, Tiphaine; Ferreira, Marisa; López, Alfredo; Moffat, Colin F.; Pierce, Graham J.; Russell, Marie; Santos, Maria B.; Spitz, Jérôme; Vingada, José V.; Webster, Lynda; Read, Fiona L.; González, Angel F.; Caurant, Florence
Ecological Indicators (2017)
Concentrations of thirty two polychlorinated biphenyls (PCBs) were determined in the blubber of five sympatric species of odontocetes stranded or by-caught along the Northwest coast of the Iberian Peninsula: common…
Comparative physiology of vocal musculature in two odontocetes, the bottlenose dolphin (Tursiops truncatus) and the harbor porpoise (Phocoena phocoena)
Thometz, Nicole M.; Dearolf, Jennifer L.; Dunkin, Robin C.; Noren, Dawn P.; Holt, Marla M.; Sims, Olivia C.; Cathey, Brandon C.; Williams, Terrie M.
Journal of Comparative Physiology B (2017)
The mechanism by which odontocetes produce sound is unique among mammals. To gain insight into the physiological properties that support sound production in toothed whales, we examined myoglobin content ([Mb]),…
Hearing thresholds of a male and a female harbor porpoise (Phocoena phocoena)
Kastelein, Ronald A.; Helder-Hoek, Lean; Van de Voorde, Shirley
The Journal of the Acoustical Society of America (2017)
To study intra-species variability in audiograms, the hearing sensitivity of a six-year-old female and a three-year-old male harbor porpoise was measured by using a standard psycho-acoustic technique under low ambient…
Response to “Resilience of harbor porpoises to anthropogenic disturbance: Must they really feed continuously?”
Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Rojano-Doñate, Laia; Shearer, Jeanne; Sveegaard, Signe; Miller, Lee A.; Siebert, Ursula; Madsen, Peter Teglberg
Marine Mammal Science (2017)
...There is, unfortunately, no unbiased way to assess the prey preference and dietary intake of free-ranging marine mammals like harbor porpoises. Although the traditional approach involving stomach content analysis of…
A novel cetacean adenovirus in stranded harbour porpoises from the North Sea: Detection and molecular characterization
van Beurden, Steven J.; IJsseldijk, Lonneke L.; van de Bildt, Marco W. G.; Begeman, Lineke; Wellehan, James F. X.; Waltzek, Thomas B.; de Vrieze, Geert; Gröne, Andrea; Kuiken, Thijs; Verheije, M. Hélène; Penzes, Judit J.
Archives of Virology (2017)
Harbour porpoises (Phocoena phocoena) are the most prevalent cetaceans in the North Sea. The fecal viral flora of 21 harbour porpoises stranded along the Dutch coastline was analyzed by a…
Diurnal variation in harbour porpoise detection – Potential implications for management
Williamson, L. D.; Brookes, K. L.; Scott, B. E.; Graham, I. M.; Thompson, P. M.
Marine Ecology Progress Series (2017)
Robust information on animal distributions and foraging behaviour is required to target management and conservation measures for protected species and populations. Visual survey data are commonly used to model these…
Two techniques of age estimation in cetaceans: GLGs in teeth and earplugs, and measuring the AAR rate in eye lens nucleus
Nielsen, Nynne H; Víkingsson, Gísli A.; Hansen, Steen H.; Ditlevsen, Susanne; Heide-Jørgensen, Mads Peter
NAMMCO Scientific Publications (2017)
The ages of three species of cetaceans were estimated by counting the growth layer groups (GLG) and measuring the aspartic acid racemization rate (kAsp) by what is referred to as…
