The social structure of animal populations is a fundamental component of their biology, influencing gene flow, habitat use, competition and co-operation around resources, and communication. However, ecological and social relationships…


Inter-species differences in polychlorinated biphenyls patterns from five sympatric species of odontocetes: Can PCBs be used as tracers of feeding ecology?

Méndez-Fernandez, Paula; Simon-Bouhet, Benoit; Bustamante, Paco; Chouvelon, Tiphaine; Ferreira, Marisa; López, Alfredo; Moffat, Colin F.; Pierce, Graham J.; Russell, Marie; Santos, Maria B.; Spitz, Jérôme; Vingada, José V.; Webster, Lynda; Read, Fiona L.; González, Angel F.; Caurant, Florence
Ecological Indicators (2017)

Concentrations of thirty two polychlorinated biphenyls (PCBs) were determined in the blubber of five sympatric species of odontocetes stranded or by-caught along the Northwest coast of the Iberian Peninsula: common…


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…


Life history of harbor porpoises (Phocoena phocoena) in Scottish (UK) waters

Learmonth, Jennifer A.; Murphy, Sinead; Luque, Patricia L.; Reid, Robert J.; Patterson, I. Anthony P.; Brownlow, Andrew; Ross, Harry M.; Barley, Jason P.; Begoña Santos, M.; Pierce, Graham J.
Mar Mam Sci (2014)

Life history parameters were determined for stranded and bycaught harbor porpoises (Phocoena phocoena) from Scottish (UK) waters (1992–2005). Fetal growth rate was 84.4 mm/mo and mean size at birth was…


Dentinal anomalies in teeth of harbour porpoises (Phocoena phocoena) from Scottish waters: Are they linked to sexual maturation and environmental events?

Luque, P. L.; Pierce, G. J.; Learmonth, J. A.; Santos, M. B.; Ieno, E.; López, A.; Reid, R. J.; Rogan, E.; González, A. F.; Boon, J.; Law, R. J.; Lockyer, C. H.
Journal of the Marine Biological Association of the United Kingdom (2009)

We examined the tooth ultra-structure of harbour porpoises (Phocoena phocoena) from Scottish waters to determine whether the incidence of mineralization anomalies could be related to certain life history events (e.g.…


Status and conservation of facultative freshwater cetaceans in Asia

Smith, B. D.; Jefferson, T. A.
The Raffles Bulletin of Zoology (2002)

Irrawaddy dolphins Orcaella brevirostris and finless porpoises Neophocaena phocaenoides are referred to as facultative freshwater cetaceans because they occupy both fresh- and nearshore marine waters. In Asia, the especially rapid…
