Aquatic Mammals (2018)
The Golden Gate Bridge in San Francisco Bay provides a non-invasive aerial platform where harbor porpoises (Phocoena phocoena) can be observed mating. We photographed 144 mating events over an eight-year…
Simulated seal scarer sounds scare porpoises, but not seals: species-specific responses to 12 kHz deterrence sounds
Mikkelsen, Lonnie; Hermannsen, Line; Beedholm, Kristian; Madsen, Peter Teglberg; Tougaard, Jakob
Royal Society Open Science (2017)
Acoustic harassment devices (AHD) or ‘seal scarers’ are used extensively, not only to deter seals from fisheries, but also as mitigation tools to deter marine mammals from potentially harmful sound…
Behavioral laterality in Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)
Platto, Sara; Zhang, C.; Pine, Matthew K.; Feng, W.K.; Yang, L.G.; Irwin, A.; Wang, D.
Behavioural Processes (2017)
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is a critically endangered species with less than 1000 individuals expected to be left in the wild. While many studies have been conducted…
Year-round spatiotemporal distribution of harbour porpoises within and around the Maryland wind energy area
Wingfield, Jessica E.; O’Brien, Michael; Lyubchich, Vyacheslav; Roberts, Jason J.; Halpin, Patrick N.; Rice, Aaron N.; Bailey, Helen
PLOS ONE (2017)
Offshore windfarms provide renewable energy, but activities during the construction phase can affect marine mammals. To understand how the construction of an offshore windfarm in the Maryland Wind Energy Area…
Behavioral responses of a harbor porpoise (Phocoena phocoena) to sounds from an acoustic porpoise deterrent
Kastelein, Ronald A.; Huybrechts, Janne; Covi, Jennifer; Helder-Hoek, Lean
Aquatic Mammals (2017)
To determine whether sounds from the FaunaGuard Porpoise Module or Acoustic Porpoise Deterrent-01 (APD-01) can deter harbor porpoises (Phocoena phocoena) far enough away from an offshore pile driving site to…
Variation in sexual behaviors in a group of captive male Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis): Motivated by physiological changes?
Wu, Hai-Ping; Hao, Yu-Jiang; Yu, Xue-Ying; Xian, Yi-Jie; Zhao, Qing-Zhong; Chen, Dao-Quan; Kuang, Xin-An; Kou, Zhang-Bin; Feng, Kang-Kang; Gong, Wei-Ming; Wang, Ding
Theriogenology (2010)
Most male mammals in temperate regions demonstrate seasonal sexual behaviors that coincide with seasonal variations in gonadal activities and androgen hormones. The Yangtze finless porpoise is a temperate freshwater cetacean…
Behavioral reactions of harbor porpoise to pile-driving noise
Tougaard, Jakob; Kyhn, Line A.; Amundin, Mats; Wennerberg, Daniel; Bordin, Carolina
Advances in Experimental Medicine and Biology (2012)
Pile driving of large steel monopiles in offshore waters has increased rapidly in recent years due to the expanding development of offshore wind energy. In particular, Phocoena phocoena (harbor porpoise)…
Responses of bottlenose dolphins and harbor porpoises to impact and vibration piling noise during harbor construction
Graham, Isla M.; Pirotta, Enrico; Merchant, Nathan D.; Farcas, Adrian; Barton, Tim R.; Cheney, Barbara; Hastie, Gordon D.; Thompson, Paul M.
Ecosphere (2017)
The development of risk assessments for the exposure of protected populations to noise from coastal construction is constrained by uncertainty over the nature and extent of marine mammal responses to…
Meals on wheels? A decade of megafaunal visual and acoustic observations from offshore oil & gas rigs and platforms in the North and Irish Seas
Todd, Victoria Louise Georgia; Warley, Jane Clare; Todd, Ian Boyer
PLOS ONE (2016)
A decade of visual and acoustic detections of marine megafauna around offshore Oil & Gas (O&G) installations in the North and Irish Seas are presented. Marine megafauna activity was monitored…
