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…
Group characteristics, site fidelity, and photo-identification of harbor porpoises, Phocoena phocoena, in Burrows Pass, Fidalgo Island, Washington
Elliser, Cindy R.; MacIver, Katrina H.; Green, Michelle
Marine Mammal Science (2017)
Little is known about harbor porpoises at the individual level or local group structure. Group characteristics, site fidelity, and photo‐identification of harbor porpoises were investigated off Fidalgo Island, Washington State.…
Long-term effectiveness of pingers on a small population of finless porpoises in Japan
Amano, M.; Kusumoto, M.; Abe, M.; Akamatsu, T.
Endangered Species Research (2017)
Finless porpoises Neophocaena spp. are under pressure from various anthropogenic impacts due to their coastal habitat. Net fishery bycatch is considered a major risk for the populations around Japan, and…
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…
Long-term association between a solitary common dolphin (Delphinus delphis delphis) and a harbour porpoise (Phocoena phocoena)
Ryan, Conor; Macleod, Greig; Dinsdale, Cameron; Cook, Stuart
Aquatic Mammals (2017)
(...)The occurrence of solitary dolphins (i.e., those in isolation from conspecifics) is well-documented in the case of bottlenose dolphins (Tursiops truncatus) along the western seaboard of northern Europe (Lockyer, 1990);…
Distribution of three sympatric cetacean species off the coast of the central-western Gulf of Thailand
Jutapruet, Suwat; Intongcome, Atichat; Wang, Xianyan; Kittiwattanawong, Kongkiat; Huang, Shiang-Lin
Aquatic Mammals (2017)
Baseline data on the distribution patterns of animals disclose the dynamic function of habitat use as it relates to the accessibility of prey, social interactions, predator-prey interactions, and inter-habitat-patch mobility.…
The effects of marine traffic on the behaviour of Black Sea harbour porpoises (Phocoena phocoena relicta) within the Istanbul Strait, Turkey
Akkaya Bas, Aylin; Christiansen, Fredrik; Öztürk, Ayaka Amaha; Öztürk, Bayram; McIntosh, Caley
PLOS ONE (2017)
Marine traffic is threatening cetaceans on a local and global scale. The Istanbul Strait is one of the busiest waterways, with up to 2,500 vessels present daily. This is the…
COSEWIC assessment and status report on the harbour porpoise (Pacific Ocean population) Phocoena phocoena vomerina in Canada
Hall, A.; Heise, K.
COSEWIC Status Reports (2017)
Wildlife Species Description and Significance The Pacific Harbour Porpoise (Phocoena phocoena vomerina) is the smallest cetacean in British Columbia (BC), ranging from 1.5 to 1.6 m and 45 to 60…
Dive heart rate in harbour porpoises is influenced by exercise and expectations
McDonald, Birgitte I.; Johnson, Mark; Madsen, Peter T.
The Journal of Experimental Biology (2017)
The dive response, a decrease in heart rate (fH) and peripheral vasoconstriction, is the key mechanism allowing breath-hold divers to perform long-duration dives. This pronounced cardiovascular response to diving has…
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…
