The social structure of animal populations is a fundamental component of their biology, influencing gene flow, habitat use, competition and co-operation around resources, and communication. However, ecological and social relationships…
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,…
Genome-wide analysis of the harbour porpoise (Phocoena phocoena) indicates isolation-by-distance across the North Atlantic and potential local adaptation in adjacent waters
Autenrieth, Marijke; Havenstein, Katja; De Cahsan, Binia; Canitz, Julia; Benke, Harald; Roos, Anna; Pampoulie, Christophe; Sigurðsson, Guðjón Már; Siebert, Ursula; Olsen, Morten Tange; Biard, Vincent; Heide-Jørgensen, Mads Peter; Öztürk, Ayaka Amaha; Öztürk, Bayram; Lawson, John W.; Tiedemann, Ralph
Conservation Genetics (2023)
The harbour porpoise (Phocoena phocoena), a highly mobile cetacean species of the Northern Hemisphere, inhabits basins that vary broadly in salinity, temperature, and food availability; such variation can drive divergent…
Hardly seen, often heard: Acoustic presence of harbour porpoises (Phocoena phocoena) in one of the most urbanised estuaries in the world
Rekdahl, Melinda L.; Trabue, Sarah G.; King-Nolan, Carissa D.; Strindberg, Samantha; Rosenbaum, Howard C.
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.…
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…
Blood transcriptome analysis provides responsive changes in gene expression between ex situ and captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)
Cao, Z.; Yin, D.; Li, Z.; Yan, Y.; Zhang, P.; Zhang, S.; Lin, D.; Hua, Z.; Zhang, J.; Ying, C.; Zhang, H.; Xu, P.; Dong, G.; Liu, K.
Fishes (2023)
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis, YFP) is an endangered species endemic to the Yangtze River in China, and it is the only freshwater whale in the genus Neophocaena.…
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…
The first case of reintroduction and behavioral adaptability of Yangtze finless porpoise
Qiu, Jian-Song; Sun, Xiao-Dong; Wang, Ding; Hao, Yu-Jiang; Zheng, Jing-Song; Li, Wei-Lun; Fan, Fei; Deng, Xiao-Jun; Mao, Jun-Feng; Zeng, Qiang; Jiang, Hua-Yan; Deng, Zai-Gui; Gong, Cheng; Xu, Chun-Yong; Wang, Ke-Xiong; Mei, Zhi-Gang
Acta Hydrobiologica Sinica (2023)
The ex situ conservation of the first-class protected animal in China, Yangtze finless porpoise (YFP), have gained preliminary success. As the last step in ex situ conservation, reintroduction is an…
Adhesive bowel obstruction (ABO) in a stranded Narrow-ridged finless porpoise (Neophocaena asiaeorientalis sunameri)
Lee, S. B.; Yuen, A. H. L.; Lee, Y. M.; Kim, S. W.; Kim, S.; Poon, C. T. C.; Jung, W. J.; Giri, S. S.; Kim, S. G.; Jo, S. J.; Park, J. H.; Hwang, M. H.; Seo, J. P.; Choe, S.; Kim, B. Y.; Park, S. C.
Animals (2023)
In this case report, we present a rare occurrence of a narrow-ridged finless porpoise (Neophocaena asiaeorientalis sunameri), discovered on the coast of Jeju Island, Republic of Korea, that was afflicted…
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…
