Evolution (2017)
Male genital diversification is likely the result of sexual selection. Female genital diversification may also result from sexual selection, although it is less well studied and understood. Female genitalia are…
Diet composition and food consumption rate of harbor porpoises (Phocoena phocoena) in the western Baltic Sea
Andreasen, Heidi; Ross, Stine D.; Siebert, Ursula; Andersen, Niels G.; Ronnenberg, Katrin; Gilles, Anita
Marine Mammal Science (2017)
Stomach content composition and prey-specific consumption rates of juvenile and adult harbor porpoises (Phocoena phocoena) were estimated from a data set including 339 stomachs collected over a 32 yr period…
Coming of age: Do female harbour porpoises (Phocoena phocoena) from the North Sea and Baltic Sea have sufficient time to reproduce in a human influenced environment?
Kesselring, Tina; Viquerat, Sacha; Brehm, Ralph; Siebert, Ursula
PLOS ONE (2017)
The harbour porpoise is the only cetacean species native to German waters. Since human pressures are suggested to shorten their reproductive lifespan, basic knowledge on reproduction is strongly required. One…
Evaluating morphometric and metabolic markers of body condition in a small cetacean, the harbor porpoise (Phocoena phocoena)
Kershaw, Joanna L.; Sherrill, Meredith; Davison, Nicholas J.; Brownlow, Andrew; Hall, Ailsa J.
Ecology and Evolution (2017)
Mammalian body condition is an important individual fitness metric as it affects both survival and reproductive success. The ability to accurately measure condition has key implications for predicting individual and…
Marine mammal sightings around oil and gas installations in the central North Sea
Delefosse, Matthieu; Rahbek, Malene Louise; Roesen, Lars; Clausen, Karin Tubbert
Journal of the Marine Biological Association of the United Kingdom (2017)
Relatively little is known about the distribution and diversity of marine mammals around offshore anthropogenic structures. We present results obtained from incidental sightings of marine mammals around oil and gas…
Trends of harbour porpoise (Phocoena phocoena) density in the southern North Sea
Peschko, Verena; Ronnenberg, Katrin; Siebert, Ursula; Gilles, Anita
Ecological Indicators (2016)
In the southern North Sea, harbour porpoise occurrence increased in recent years after a phase of low abundances during earlier decades. Only very few studies on porpoise presence in the…
Harbour porpoises, Phocoena phocoena, in the Mediterranean Sea and adjacent regions
Fontaine, M. C.
Advances in Marine Biology (2016)
The harbour porpoise, Phocoena phocoena, is one of the best studied cetacean species owing to its common distribution along the coastal waters of the Northern Hemisphere. In European waters, strandings…
Identification of high-risk areas for harbour porpoise Phocoena phocoena bycatch using remote electronic monitoring and satellite telemetry data
Kindt-Larsen, L.; Berg, C. W.; Tougaard, J.; Sørensen, T. K.; Geitner, K.; Northridge, S.; Sveegaard, S.; Larsen, F.
Marine Ecology Progress Series (2016)
The bycatch of harbour porpoise Phocoena phocoena is an issue of major concern for fisheries management and for porpoise conservation. We used high-resolution spatial and temporal data on porpoise abundance…
A suspected scavenging event by red foxes (Vulpes vulpes) on a live, stranded harbour porpoise (Phocoena phocoena)
Haelters, Jan; Everaarts, Eligius; Bunskoek, Paulien; Begeman, Lineke; Hinrichs, John W. J.; IJsseldijk, Lonneke L.
Aquatic Mammals (2016)
(...) At about 0900 h on 15 February 2014, a live harbour porpoise (Phocoena phocoena) was found on the beach of Koksijde, Belgium. The stranding occurred on a sandy beach,…
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…
