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,…
The click production of captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaorientalis) is influenced by social and environmental factors
Serres, Agathe; Xu, Chen; Hao, Yujiang; Wang, Ding
Animals (2021)
Yangtze finless porpoises use high-frequency clicks to navigate, forage, and communicate. The way in which click production may vary depending on social or environmental context has never been investigated. A…
Out of sight, out of mind: How conservation is failing European porpoises
Carlén, Ida; Nunny, Laetitia; Simmonds, Mark P.
Frontiers in Marine Science (2021)
The conservation of harbor porpoises (Phocoena phocoena) appears to be failing in Europe. There are particular concerns about this species in the Baltic Proper, Black, and Mediterranean Seas, as well…
Harbor porpoise aggregations in the Salish Sea
Anderson, Dave; Shuster, Laurie; Elliser, Cindy R.; MacIver, Katrina; Gless, Erin Johns; Krieger, Johannes; Hall, Anna
Oceans (2023)
Harbor porpoises are typically seen in small groups of 1–3 individuals, with aggregations of 20+ individuals treated as rare events. Since the 1990s, the harbor porpoise population in the Salish…
Arkona offshore wind farm. Passive acoustic monitoring – Field work report.
Sveegaard, S.
(2023)
In July 2022, Aarhus University was contracted by SWECO AB to conduct a one-year baseline study and impact assessment of harbour porpoises as well as noise monitoring within the pre-investigation…
Harbor porpoise losing its edge: Genetic time series suggests a rapid population decline in Iberian waters over the last 30 years
Ben Chehida, Yacine; Stelwagen, Tjibbe; Hoekendijk, Jeroen P. A.; Ferreira, Marisa; Eira, Catarina; Torres‐Pereira, Andreia; Nicolau, Lidia; Thumloup, Julie; Fontaine, Michael C.
Ecology and Evolution (2023)
Impact of climate change is expected to be especially noticeable at the edges of a species' distribution, where they meet suboptimal habitat conditions. In Mauritania and Iberia, two genetically differentiated…
