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…
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…
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…
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…
Two decades’ variation of trace elements in bones of the endangered East Asian Finless Porpoise (Neophocaena asaeorientalis sunameri) from the East China Sea, China
Hao, Xiuqing; Shan, Hong; Wu, Caiwen; Zhang, Di; Chen, Bingyao
Biological Trace Element Research (2020)
There has been increasing concern about trace element accumulation in finless porpoises over the past decades, while the long-term variation of its concentration has been little known. Since most soft…
Distribution and abundance of cetaceans in Icelandic waters over 30 years of aerial surveys
Pike, Daniel; Gunnlaugsson, Thorvaldur; Sigurjonsson, Johann; Vikingsson, Gisli
NAMMCO Scientific Publications (2020)
Beginning in 1986, 7 aerial surveys covering the coastal waters of Iceland have been conducted up to 2016. In addition, several partial surveys covering portions of the same area and…
Evaluating management strategies for marine mammal populations: An example for multiple species and multiple fishing sectors in Iceland
Punt, André E; Siple, Margaret; Sigurðsson, Guðjón M.; Víkingsson, Gisli; Francis, Tessa B.; Granquist, Sandra Magdalena; Hammond, Philip S; Heinemann, Dennis; Long, Kristy J.; Moore, Jeffrey E.; Sepúlveda, Maritza; Reeves, Randall R.; Wade, Paul R.; Williams, Rob; Zerbini, Alexandre N.
Canadian Journal of Fisheries and Aquatic Sciences (2020)
A Management Strategy Evaluation is used to estimate success at achieving conservation goals for marine mammals while also aiming to minimize impacts on commercial fisheries. It is intended to improve…
