Frontiers in Marine Science (2023)
The New York-New Jersey (NY-NJ) Harbour Estuary and surrounding waters support the largest port along the U.S. East Coast, commercial and recreational fishing, and a burgeoning offshore wind energy industry.…
Knowing the fishery to know the bycatch: Bias-corrected estimates of harbour porpoise bycatch in gillnet fisheries
Kindt-Larsen, Lotte; Glemarec, Gildas; Berg, Casper W.; Königson, Sara; Kroner, Anne-Mette; Søgaard, Mathias; Lusseau, David
Proceedings of the Royal Society B: Biological Sciences (2023)
Incidental captures (bycatch) remain a key global conservation threat for cetaceans. Bycatch of harbour porpoise Phocoena phocoena in set gillnets is routinely monitored in European Union fisheries, but generally relies…
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…
Diving on damage – The muscle transcriptome of parasitic infested harbor porpoises (Phocoena phocoena) hints at oxidative stress but not hypoxia
Dönmez, Eda Merve; Siebert, Ursula; Fabrizius, Andrej
Frontiers in Marine Science (2023)
The only native cetacean in German waters, the harbor porpoise (Phocoena phocoena), is impacted by numerous pathological lesions in the respiratory tract mainly caused by parasites or bacteria. Although harbor…
Evolutionary history and seascape genomics of harbour porpoises (Phocoena phocoena) across environmental gradients in the North Atlantic and adjacent waters
Celemín, Enrique; Autenrieth, Marijke; Roos, Anna; Pawliczka, Iwona; Quintela, María; Lindstrøm, Ulf; Benke, Harald; Siebert, Ursula; Lockyer, Christina; Berggren, Per; Özturk, A. Amaha; Özturk, Bayram; Lesage, Véronique; Tiedemann, Ralph
Molecular Ecology Resources (2023)
The Harbour porpoise (Phocoena phocoena) is a highly mobile cetacean species primarily occurring in coastal and shelf waters across the Northern hemisphere. It inhabits heterogeneous seascapes broadly varying in salinity…
Harassment and killing of porpoises (“phocoenacide”) by fish‐eating Southern Resident killer whales (Orcinus orca)
Giles, Deborah A.; Teman, Sarah J.; Ellis, Samuel; Ford, John K. B.; Shields, Monika W.; Hanson, M. Bradley; Emmons, Candice K.; Cottrell, Paul E.; Baird, Robin W.; Osborne, Richard W.; Weiss, Michael; Ellifrit, David K.; Olson, Jennifer K.; Towers, Jared R.; Ellis, Graeme; Matkin, Dena; Smith, Courtney E.; Raverty, Stephen A.; Norman, Stephanie A.; Gaydos, Joseph K.
Marine Mammal Science (2023)
Endangered Southern Resident killer whales (Orcinus orca) are fish-eaters that preferentially prey on adult Chinook salmon (Oncorhynchus tshawytscha). Despite being salmon specialists, individuals from all three killer whale pods (J,…
An overview of the status of sturgeons and cetaceans accidentally captured in southern Black Sea coastal zone of Türkiye
Özdemir, Süleyman; Erdem, Ercan; Birinci Özdemir, Zekiye
Marine Science and Technology Bulletin (2023)
This study was conducted out in the southern Black Sea coastal zone, in 2011-2016 fishing seasons. In the study, bycatch of sturgeons and cetaceans were examined both in small scale…
Implications of porpoise echolocation and dive behaviour on passive acoustic monitoring
Macaulay, Jamie Donald John; Rojano-Doñate, Laia; Ladegaard, Michael; Tougaard, Jakob; Teilmann, Jonas; Marques, Tiago A.; Siebert, Ursula; Madsen, Peter Teglberg
The Journal of the Acoustical Society of America (2023)
Harbour porpoises are visually inconspicuous but highly soniferous echolocating marine predators that are regularly studied using passive acoustic monitoring (PAM). PAM can provide quality data on animal abundance, human impact,…
Wild harbour porpoises startle and flee at low received levels from acoustic harassment device
Elmegaard, Siri L.; Teilmann, Jonas; Rojano-Doñate, Laia; Brennecke, Dennis; Mikkelsen, Lonnie; Balle, Jeppe D.; Gosewinkel, Ulrich; Kyhn, Line A.; Tønnesen, Pernille; Wahlberg, Magnus; Ruser, Andreas; Siebert, Ursula; Madsen, Peter Teglberg
Scientific Reports (2023)
Acoustic Harassment Devices (AHD) are widely used to deter marine mammals from aquaculture depredation, and from pile driving operations that may otherwise cause hearing damage. However, little is known about…
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…
