Ocean & Coastal Management (2019)
Harbour porpoise (Phocoena phocoena) are protected in the UK by the Wildlife and Countryside Act (1981). Understanding the impact of anthropogenic pressures is fundamental for effective protection under this act…
Social responses of travelling finless porpoises to boat traffic risk in Misumi West Port, Ariake Sound, Japan
Morimura, Naruki; Mori, Yusuke
PLOS ONE (2019)
Anthropogenic effects have created various risks for wild animals. Boat traffic is one of the most fatal risks for marine mammals. Individual behavioral responses of cetaceans, including diving behavior such…
Behavioral responses of harbor porpoises (Phocoena phocoena) to sonar playback sequences of sweeps and tones (3.5-4.1 kHz)
Kastelein, Ronald A.; Helder-Hoek, Lean; Van de Voorde, Shirley; de Winter, Simone; Janssen, Susan; Ainslie, Michael A.
Aquatic Mammals (2018)
Naval sonar signals may affect the behavior of harbor porpoises (Phocoena phocoena). The 53C sonar system produces 1,600 ms sonar signals in the 3.5 to 4.1 kHz band, each consisting…
Testing two types of acoustic deterrent devices (pingers) to reduce harbour porpoise, Phocoena phocoena (Cetacea: Phocoenidae), by catch in turbot (Psetta maxima) set gillnet fishery in the Black Sea, Turkey
Bilgin, S.; Köse, Ö.
Cahiers de Biologie Marine (2018)
Field experiments with Aquamark 100 and Aquamark 200 pingers were conducted in the bottom set gill net fishery for turbot in the Black Sea coast between March and June 2012.…
Noise affects porpoise click detections – the magnitude of the effect depends on logger type and detection filter settings
Clausen, Karin Tubbert; Tougaard, Jakob; Carstensen, Jacob; Delefosse, Matthieu; Teilmann, Jonas
Bioacoustics (2018)
Automatic click detectors and full-bandwidth sound recorders are widely used in passive acoustic monitoring of small cetaceans. Detection of these signals depends on a variety of factors, including signal to…
Crossing boundaries for cetacean conservation: Setting research priorities to guide management of harbour porpoises
IJsseldijk, Lonneke L.; ten Doeschate, Mariel T. I.; Davison, Nicholas J.; Gröne, Andrea; Brownlow, Andrew C.
Marine Policy (2018)
Effective management of natural resources involves a multidisciplinary perspective to address complex issues in data poor-environments. With mobile species that do not conform to human-defined borders a cross-boundary approach is…
High rates of vessel noise disrupt foraging in wild harbour porpoises (Phocoena phocoena)
Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Siebert, Ursula; Galatius, Anders; Dietz, Rune; Madsen, Peter Teglberg
Proceedings of the Royal Society B: Biological Sciences (2018)
Shipping is the dominant marine anthropogenic noise source in the world's oceans, yet we know little about vessel encounter rates, exposure levels and behavioural reactions for cetaceans in the wild,…
Spatial avoidance to experimental increase of intermittent and continuous sound in two captive harbour porpoises
Kok, Annebelle C. M.; Engelberts, J. Pamela; Kastelein, Ronald A.; Helder-Hoek, Lean; Van de Voorde, Shirley; Visser, Fleur; Slabbekoorn, Hans
Environmental Pollution (2018)
The continuing rise in underwater sound levels in the oceans leads to disturbance of marine life. It is thought that one of the main impacts of sound exposure is the…
Does interspecific competition drive patterns of habitat use and relative density in harbour porpoises?
Díaz López, Bruno; Methion, Séverine
Marine Biology (2018)
Determining the drivers that are responsible for the fine-scale distribution of cetacean species is fundamental to understand better how they respond to changes in their environment. We utilized information theoretic…
The possible effects of high vessel traffic on the physiological parameters of the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis ssp. asiaeorientalis)
Nabi, Ghulam; Hao, Yujiang; McLaughlin, Richard William; Wang, Ding
Frontiers in Physiology (2018)
Poyang is the largest freshwater lake in China, where the acoustic environment and space for the critically endangered Yangtze finless porpoises (YFPs) has been altered by heavy vessel traffic and…
