The oomycete Pythium flevoense was diagnosed as the cause of dermatitis in a young adult female harbour porpoise (Phocoena phocoena) that had been trapped in a pound net in a…
Vorticity preference of the Yangtze finless porpoise (Neophocaena asiaeorientalis) during the dry season at the Wanhe River Estuary confluence
Ding, Rui; Zhang, Xiaoke; Chen, Minmin; Lian, Yuxi; Yu, Daoping
Ecological Modelling (2023)
The Yangtze finless porpoise (Neophocaena asiaeorientalis) is critically endangered. Finless porpoises rely on small fish as their primary food source. Fish distribution is impacted by topography and vorticity (i.e., water…
Recent progress and future directions for conservation of the Yangtze finless porpoise (Neophocaena asiaorientalis asiaorientalis)

Der Zoologische Garten (2023)
With the functional extinction of the Yangtze River dolphin or baiji (Lipotes vexillifer) based on the survey conducted in 2006, the Yangtze finless porpoise (Neophocaena asiaorientalis) is now the only…
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…
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,…
Ship noise causes tagged harbour porpoises to change direction or dive deeper
Frankish, Caitlin K.; von Benda-Beckmann, Alexander M.; Teilmann, Jonas; Tougaard, Jakob; Dietz, Rune; Sveegaard, Signe; Binnerts, Bas; de Jong, Christ A. F.; Nabe-Nielsen, Jacob
Marine Pollution Bulletin (2023)
Shipping is the most pervasive source of marine noise pollution globally, yet its impact on sensitive fauna remains unclear. We tracked 10 harbour porpoises for 5–10 days to determine exposure…
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…
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…
Seasonal abundance estimates of cetaceans in the southern Black Sea (Sinop), Türkiye
Özsandıkçı, Uğur; Özdemir, Süleyman
Marine Mammal Science (2023)
The availability of reliable information on the abundance and distribution of threatened species is fundamental to evaluating their conservation status and taking the necessary measures to implement effective management. The…
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…
