Population structure of bycaught harbour porpoise (Phocoena phocoena) in Norway
Quintela, María; Besnier, François; Seliussen, Bjørghild; Glover, Kevin A.; Lindstrøm, Ulf
Marine Biology Research (2020)
The preference for coastal habitats makes the harbour porpoise, Phocoena phocoena, vulnerable to fisheries conflicts and hence prone to die due to entangling in fishing nets. An opportunistic sampling of…
Asymmetric and spiraled genitalia coevolve with unique lateralized mating behavior
Orbach, Dara N.; Brennan, Patricia L. R.; Hedrick, Brandon P.; Keener, William; Webber, Marc A.; Mesnick, Sarah L.
Scientific Reports (2020)
Asymmetric genitalia and lateralized mating behaviors occur in several taxa, yet whether asymmetric morphology in one sex correlates or coevolves with lateralized mating behavior in the other sex remains largely…
Juvenile harbor porpoises in the UK are exposed to a more neurotoxic mixture of polychlorinated biphenyls than adults
Williams, Rosie S.; Curnick, David J.; Barber, Jonathan L.; Brownlow, Andrew; Davison, Nicholas J.; Deaville, Rob; Perkins, Matthew; Jobling, Susan; Jepson, Paul D.
Science of The Total Environment (2020)
Polychlorinated biphenyls (PCBs) are a group of 209 persistent and bio-accumulative toxic pollutants present as complex mixtures in human and animal tissues. Harbor porpoises accumulate some of the highest levels…
Effectiveness of pingers on the harbour porpoise Phocoena phocoena relicta Abel, 1905 (Cetacea: Phocoenidae) in Turkey as revealed by shore-based observations
Özsandikçi, Uğur; Gönener, Sedat
Acta Zoologica Bulgarica (2020)
The aim of the present study was to assess the effectiveness of pinger devices on the Black-Sea harbour porpoises Phocoena phocoena relicta. The study was carried out in Sinop, Turkey,…
High resolution three-dimensional beam radiation pattern of harbour porpoise clicks with implications for passive acoustic monitoring
Macaulay, Jamie D. J.; Malinka, Chloe E.; Gillespie, Douglas; Madsen, Peter T.
The Journal of the Acoustical Society of America (2020)
The source properties and radiation patterns of animal vocalisations define, along with propagation and noise conditions, the active space in which these vocalisations can be detected by conspecifics, predators, prey,…
Investigating the distribution of the Yangtze finless porpoise in the Yangtze River using environmental DNA
Tang, Yongkai; Wu, Yunsheng; Liu, Kai; Li, Jianlin; Li, Hongxia; Wang, Qin; Yu, Juhua; Xu, Pao
PLOS ONE (2019)
Determining the distribution of the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis, YFP) in the Yangtze River has to date relied on traditional visual and counting methods, but such field surveys…
Behavioral responses of harbor porpoises (Phocoena phocoena) to U.S. Navy 53C sonar signals in noise
Kastelein, Ronald A.; Ainslie, Michael A.; van Kester, Ruby
Aquatic Mammals (2019)
Naval sonar systems produce signals that may affect the behavior of harbor porpoises (Phocoena phocoena), and behavioral responses may be influenced by the received signal and by the signal-to-noise ratio…
