Marine mammals have adapted to forage while holding their breath in a suite of aquatic habitats from shallow rivers to deep oceans. The key to tolerate such extensive apnea is…
Temporal and spatial trends in stranding records of cetaceans on the Irish coast, 2002–2014
McGovern, Barry; Culloch, Ross M.; O'Connell, Michael; Berrow, Simon
Journal of the Marine Biological Association of the United Kingdom (2016)
Using Irish strandings data collected between 2002 and 2014, seasonal and annual trends in the number of strandings for all strandings identified to species level (N = 1480), and for…
Ultra-high foraging rates of harbor porpoises make them vulnerable to anthropogenic disturbance
Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Rojano-Doñate, Laia; Shearer, Jeanne; Sveegaard, Signe; Miller, Lee A.; Siebert, Ursula; Madsen, Peter Teglberg
Current Biology (2016)
The question of how individuals acquire and allocate resources to maximize fitness is central in evolutionary ecology. Basic information on prey selection, search effort, and capture rates are critical for…
Harbour porpoise movement strategy affects cumulative number of animals acoustically exposed to underwater explosions
Aarts, G.; von Benda-Beckmann, A. M.; Lucke, K.; Sertlek, H. Ö.; van Bemmelen, R.; Geelhoed, S. C. V.; Brasseur, S.; Scheidat, M.; Lam, F. P. A.; Slabbekoorn, H.; Kirkwood, R.
Marine Ecology Progress Series (2016)
Anthropogenic sound in the marine environment can have negative consequences for marine fauna. Since most sound sources are intermittent or continuous, estimating how many individuals are exposed over time remains…
Asymmetry of the nasofacial skull in toothed whales (Odontoceti)
Huggenberger, S.; Leidenberger, S.; Oelschläger, H. H. A.
Journal of Zoology (2016)
In this study, the nasal asymmetry of odontocetes (toothed whales) was analyzed morphometrically by placing landmarks on photographed nasofacial skulls from 12 different species and genera that belong to four…
Identification of novel cetacean poxviruses in cetaceans stranded in south west England
Barnett, James; Dastjerdi, Akbar; Davison, Nick; Deaville, Rob; Everest, David; Peake, Julie; Finnegan, Christopher; Jepson, Paul; Steinbach, Falko
PLoS ONE (2015)
Poxvirus infections in marine mammals have been mainly reported through their clinical lesions and electron microscopy (EM). Poxvirus particles in association with such lesions have been demonstrated by EM and…
Temporal changes in abundance of harbor porpoise (Phocoena phocoena) inhabiting the inland waters of Southeast Alaska
Dahlheim, Marilyn E.; Zerbini, Alexandre N.; Waite, Janice M.; Kennedy, Amy S.
Fishery Bulletin (2015)
Abundance of harbor porpoise (Phocoena phocoena) was estimated from data collected during vessel surveys conducted throughout the inland waters of Southeast Alaska. Line-transect methods were used during 18 seasonal surveys…
Developing a new research tool for use in free-ranging cetaceans: recovering cortisol from harbour porpoise skin
Bechshoft, T.; Wright, A. J.; Weisser, J. J.; Teilmann, J.; Dietz, R.; Hansen, M.; Bjorklund, E.; Styrishave, B.
Conservation Physiology (2015)
We developed a chemical analytical procedure for sampling, extracting and determining epidermal skin cortisol concentrations (SCCs) in the harbour porpoise (Phocoena phocoena) using gas chromatography–tandem mass spectrometry. In brief, this…
Characteristics and propagation of airgun pulses in shallow water with implications for effects on small marine mammals
Hermannsen, Line; Tougaard, Jakob; Beedholm, Kristian; Nabe-Nielsen, Jacob; Madsen, Peter Teglberg
PLOS ONE (2015)
Airguns used in seismic surveys are among the most prevalent and powerful anthropogenic noise sources in marine habitats. They are designed to produce most energy below 100 Hz, but the…
Homosexual and masturbating behaviors in a group of captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)
ZHANG, Changqun; ZHENG, Yang; PLATTO, Sara; HAO, Yujiang; WANG, Ding
Acta Theriologica Sinica (2015)
Similar to terrestrial mammals, male-female sexual behavior is significant for the survival and continuation of certain cetacean species. However, non-reproductive mating behaviors, i.e. homosexual behaviors and masturbation, are widespread in…
