PLOS ONE (2019)
Odontocetes have evolved a rich diversity of prey- and habitat-specific foraging strategies, which allows them to feed opportunistically on locally and temporally abundant prey. While habitat-specific foraging strategies have been…
Pingers reduce the activity of Burmeister’s porpoise around small-scale gillnet vessels
Clay, T. A.; Alfaro-Shigueto, J.; Godley, B. J.; Tregenza, N.; Mangel, J. C.
Marine Ecology Progress Series (2019)
Incidental mortality (bycatch) in gillnet fisheries is a major threat to many cetacean populations. Acoustic alarms or pingers are a widely adopted management tool used to deter dolphins and porpoises…
Porpoise click classifier (PorCC): A high-accuracy classifier to study harbour porpoises (Phocoena phocoena) in the wild
Cosentino, Mel; Guarato, Francesco; Tougaard, Jakob; Nairn, David; Jackson, Joseph C.; Windmill, James F. C.
The Journal of the Acoustical Society of America (2019)
Harbour porpoises are well-suited for passive acoustic monitoring (PAM) as they produce highly stereotyped narrow-band high-frequency (NBHF) echolocation clicks. PAM systems must be coupled with a classification algorithm to identify…
High resolution three-dimensional beam radiation pattern of harbour porpoise clicks with implications for passive acoustic monitoring
Macaulay, Jamie D. J.; Malinka, Chloe E.; Gillespie, Douglas; Madsen, Peter T.
The Journal of the Acoustical Society of America (2020)
The source properties and radiation patterns of animal vocalisations define, along with propagation and noise conditions, the active space in which these vocalisations can be detected by conspecifics, predators, prey,…
Harbor porpoise (Phocoena phocoena) reaction to a 3D seismic airgun survey in the North Sea
Sarnocińska, Joanna; Teilmann, Jonas; Balle, Jeppe Dalgaard; van Beest, Floris M.; Delefosse, Matthieu; Tougaard, Jakob
Frontiers in Marine Science (2020)
The most common cetacean in the North Sea is the harbor porpoise (Phocoena phocoena). Underwater noise is increasingly recognized as a source of impact on the marine environment and seismic…
Population survey showing hope for population recovery of the critically endangered Yangtze finless porpoise
Huang, Jie; Mei, Zhigang; Chen, Mao; Han, Yi; Zhang, Xinqiao; Moore, Jeffrey E.; Zhao, Xiujiang; Hao, Yujiang; Wang, Kexiong; Wang, Ding
Biological Conservation (2020)
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis), has experienced rapid declines in recent decades. We estimate its abundance based on surveys conducted between November and December 2017 in the main-stem…
Using passive acoustic monitoring to investigate the occurrence of cetaceans in a protected marine area in northwest Ireland
Todd, Nicole R. E.; Cronin, Michelle; Luck, Cian; Bennison, Ashley; Jessopp, Mark; Kavanagh, Ailbhe S.
Estuarine, Coastal and Shelf Science (2020)
Under the EU Habitats Directive, cetacean species must be maintained at favourable conservation status in European waters. Whether this is achieved via protected area designation, curtailment of activities such as…
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…
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.…
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…
