Marine Ecology Progress Series (2018)
Harbour porpoises Phocoena phocoena are common in continental shelf areas of the North Atlantic, but little information is available on their occurrence outside coastal areas. In this study, 30 harbour…
Seasonal changes in food consumption, respiration rate, and body condition of a male harbor porpoise (Phocoena phocoena)
Kastelein, Ronald A.; Helder-Hoek, Lean; Jennings, Nancy
Aquatic Mammals (2018)
Seasonal changes in food consumption, respiration rate, and body condition in a healthy captive male harbor porpoise (Phocoena phocoena) from the North Sea were recorded over 8 y. He was…
Estimating effective detection area of static passive acoustic data loggers from playback experiments with cetacean vocalisations
Nuuttila, Hanna K.; Brundiers, Katharina; Dähne, Michael; Koblitz, Jens C.; Thomas, Len; Courtene‐Jones, Winnie; Evans, Peter G. H.; Turner, John R.; Bennell, Jim D.; Hiddink, Jan G.
Methods in Ecology and Evolution (2018)
Passive acoustic monitoring (PAM) is used for many vocal species. However, few studies have quantified the fraction of vocalisations captured, and how animal distance and sound source level affect detection…
Acoustic monitoring reveals the times and tides of harbor porpoise (Phocoena phocoena) distribution off central Oregon, U.S.A.
Holdman, Amanda K.; Haxel, Joseph H.; Klinck, Holger; Torres, Leigh G.
Marine Mammal Science (2018)
Harbor porpoises (Phocoena phocoena) are commonly observed in Oregon's nearshore marine environment yet knowledge of their ecosystem use and behavior remains limited, generating concerns for potential impacts on this species…
The sex life of harbor porpoises (Phocoena phocoena): Lateralized and aerial behavior
Keener, William; Webber, Marc A.; Szczepaniak, Isidore D.; Markowitz, Tim M.; Orbach, Dara N.
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…
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…
High field metabolic rates of wild harbour porpoises
Rojano-Doñate, Laia; McDonald, Birgitte I.; Wisniewska, Danuta M.; Johnson, Mark; Teilmann, Jonas; Wahlberg, Magnus; Højer-Kristensen, Jakob; Madsen, Peter T.
The Journal of Experimental Biology (2018)
Reliable estimates of field metabolic rates (FMRs) in wild animals are essential for quantifying their ecological roles, as well as for evaluating fitness consequences of anthropogenic disturbances. Yet, standard methods…
Tissue-specific accumulation and body burden of parabens and their metabolites in small cetaceans
Jeong, Yunsun; Xue, Jingchuan; Park, Kyum Joon; Kannan, Kurunthachalam; Moon, Hyo-Bang
Environmental Science & Technology (2018)
Parabens have been of global concern due to their endocrine disrupting properties. However, few studies have reported tissue-specific distribution of parabens in wildlife. In this study, we measured parabens and…
Loop-mediated isothermal amplification (LAMP) as a confirmatory and rapid DNA detection method for grey seal (Halichoerus grypus) predation on harbour porpoises (Phocoena phocoena)
Heers, Teresa; van Neer, Abbo; Becker, André; Gross, Stephanie; Hansen, Kirstin Anderson; Siebert, Ursula; Abdulmawjood, Amir
Journal of Sea Research (2018)
An increasing number of harbour porpoises along the coastlines of northern Europe are victims of attacks by preying grey seals. To confirm grey seal attacks at a molecular level, a…
Not just fat: Investigating the proteome of cetacean blubber tissue
Kershaw, Joanna L.; Botting, Catherine H.; Brownlow, Andrew; Hall, Ailsa J.
Conservation Physiology (2018)
Mammalian adipose tissue is increasingly being recognized as an endocrine organ involved in the regulation of a number of metabolic processes and pathways. It responds to signals from different hormone…
