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…
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…
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.…
A drone study of sociality in the finless porpoise Neophocaena asiaeorientalis in the Ariake Sound, Japan
Morimura, Naruki; Itahara, Akihiro; Brooks, James; Mori, Yusuke; Piao, Yige; Hashimoto, Hiroki; Mizumoto, Itsuki
Drones (2023)
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…
Visual deprivation induces a stronger dive response in a harbor porpoise
Bakkeren, C.; Ladegaard, M.; Hansen, K. A.; Wahlberg, M.; Madsen, P. T.; Rojano-Doñate, L.
iScience (2023)
The dive response allows marine mammals to perform prolonged breath-hold dives to access rich marine prey resources. Via dynamic adjustments of peripheral vasoconstriction and bradycardia, oxygen consumption can be tailored…
Distribution and speed of recreational boats in Danish waters based on coastal observations and satellite images: Predicting where boats may affect harbour porpoises
Hao, Xiuqing; Nabe-Nielsen, Jacob
Ocean & Coastal Management (2023)
Danish coastal waters are a hotspot for recreational boating and harbour porpoises (Phocoena phocoena), but as there is little data on the boats’ speeds and distributions, it is difficult to…
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…
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…
Contextual impacts on individual and synchronous breathing rate variations in three captive odontocete groups
Serres, Agathe; Hao, Yujiang; Wang, Ding
Zoo Biology (2020)
Breathing rates are often collected both in the wild and in captivity to inform on cetaceans' internal state. However, few studies have investigated the effect of various factors on this…
Social, reproductive and contextual influences on fecal glucocorticoid metabolites in captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) and bottlenose dolphins (Tursiops truncatus)
Serres, Agathe; Robeck, Todd; Deng, Xiaojun; Steinman, Karen; Hao, Yujiang; Wang, Ding
Journal of Zoological and Botanical Gardens (2020)
Although the use of fecal glucocorticoid metabolite (FGCM) measurements as non-invasive biomarkers for the stress response in mammals has increased, few studies have been conducted in odontocetes. We investigated if…
