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…
Biological variables and health status affecting inorganic element concentrations in harbour porpoises (Phocoena phocoena) from Portugal (western Iberian Peninsula)
Ferreira, Marisa; Monteiro, Silvia S.; Torres, Jordi; Oliveira, Isabel; Sequeira, Marina; López, Alfredo; Vingada, José; Eira, Catarina
Environmental Pollution (2016)
The coastal preferences of harbour porpoise (Phocoena phocoena) intensify their exposure to human activities. The harbour porpoise Iberian population is presently very small and information about the threats it endures…
Response to Kopps & Palsboll
van der Plas-Duivesteijn, Suzanne; Kraaijeveld, Ken
Journal of Sea Research (2016)
(...) Kopps and Palsboll conclude by implying that conservation research should somehow be held to higher standards of rigor than more basic academic endeavors, because it has ‘direct impact on…
Assessing auditory evoked potentials of wild harbor porpoises (Phocoena phocoena)
Ruser, Andreas; Dähne, Michael; van Neer, Abbo; Lucke, Klaus; Sundermeyer, Janne; Siebert, Ursula; Houser, Dorian S.; Finneran, James J.; Everaarts, Eligius; Meerbeek, Jolanda; Dietz, Rune; Sveegaard, Signe; Teilmann, Jonas
The Journal of the Acoustical Society of America (2016)
Testing the hearing abilities of marine mammals under water is a challenging task. Sample sizes are usually low, thus limiting the ability to generalize findings of susceptibility towards noise influences.…
Conditioned hearing sensitivity change in the harbor porpoise (Phocoena phocoena)
Nachtigall, Paul E.; Supin, Alexander Ya.; Pacini, Aude F.; Kastelein, Ronald A.
The Journal of the Acoustical Society of America (2016)
Hearing sensitivity, during trials in which a warning sound preceding a loud sound, was investigated in two harbor porpoises (Phocoena phocoena). Sensitivity was measured using pip-train test stimuli and auditory…
Trace element concentrations, risks and their correlation with metallothionein genes polymorphism: A case study of narrow-ridged finless porpoises (Neophocaena asiaeorientalis) in the East China Sea
Liu, Jun; Chen, Bingyao; Jefferson, Thomas Allen; Wang, Hui; Yang, Guang
Science of the Total Environment (2016)
The concentration of trace elements (TEs) and their risk to narrow-ridged finless porpoises (Neophocaena asiaeorientalis) are still unclear. The present study determined the concentration of typical TEs in liver, kidney,…
Cognitive control of heart rate in diving harbor porpoises
Elmegaard, Siri L.; Johnson, Mark; Madsen, Peter T.; McDonald, Birgitte I.
Current Biology (2016)
Marine mammals have adapted to forage while holding their breath in a suite of aquatic habitats from shallow rivers to deep oceans. The key to tolerate such extensive apnea is…
Temporal and spatial trends in stranding records of cetaceans on the Irish coast, 2002–2014
McGovern, Barry; Culloch, Ross M.; O'Connell, Michael; Berrow, Simon
Journal of the Marine Biological Association of the United Kingdom (2016)
Using Irish strandings data collected between 2002 and 2014, seasonal and annual trends in the number of strandings for all strandings identified to species level (N = 1480), and for…
Ultra-high foraging rates of harbor porpoises make them vulnerable to anthropogenic disturbance
Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Rojano-Doñate, Laia; Shearer, Jeanne; Sveegaard, Signe; Miller, Lee A.; Siebert, Ursula; Madsen, Peter Teglberg
Current Biology (2016)
The question of how individuals acquire and allocate resources to maximize fitness is central in evolutionary ecology. Basic information on prey selection, search effort, and capture rates are critical for…
