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…
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…
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,…
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…
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,…
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…
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…
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…
Variation of blubber thickness of the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) in human care: Adaptation to environmental temperature
Tang, Bin; Hao, Yujiang; Wang, Chaoqun; Deng, Zhengyu; Shu, Guilin; Wang, Kexiong; Wang, Ding
Water Biology and Security (2023)
Blubber thickness (BT) has a seasonal pattern in most small cetaceans in temperate and polar regions, which may be a crucial adaptive mechanism in response to environmental temperature changes. However,…
Variations in echolocation click characteristics of finless porpoise in response to day/night and absence/presence of vessel noise
Ogawa, Mayu; Kimura, Satoko S.
PLOS ONE (2023)
Small odontocetes produce echolocation clicks to feed and navigate, making it an essential function for their survival. Recently, the effect of vessel noise on small odontocetes behavior has attracted attention…
