Marine Pollution Bulletin (1996)
Levels of organochlorine compounds (PCDD, PCDF, PCB and organochlorine pesticides) were determined in cetaceans collected from the west coast of North America between 1986 and 1989. The samples included gray…
Characterization, optimization, and validation of environmental DNA (eDNA) markers to detect an endangered aquatic mammal
Ma, Hongjuan; Stewart, Kathryn; Lougheed, Stephen; Zheng, Jinsong; Wang, Yuxiang; Zhao, Jianfu
Conservation Genetics Resources (2016)
Environmental DNA (eDNA) represents a sensitive and efficient method for noninvasively sampling rare or otherwise hard to monitor taxa, potentially making it a powerful tool for conservation management. Still, this…
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…
Listening to echolocation clicks with PODs
Tregenza, Nick; Dawson, Steve; Rayment, Will; Verfuss, Ursula
Modern Acoustics and Signal Processing (2016)
Monitoring echolocation using SAMs—static acoustic monitors—such as T-PODs or, more recently, C-PODs—has provided a wealth of information on the fine-scale distribution and activity of dolphins, porpoises and other toothed whales.…
Investigating potential associations between chronic exposure to polychlorinated biphenyls and infectious disease mortality in harbour porpoises from England and Wales
Jepson, Paul D.; Bennett, Peter M.; Allchin, Colin R.; Law, Robin J.; Kuiken, Thijs; Baker, John R.; Rogan, Emer; Kirkwood, James K.
Science of the Total Environment (1999)
Bioaccumulation of immunosuppressive organochlorines like polychlorinated biphenyls (PCBs) may pose a threat to the health and viability of cetacean populations. To investigate possible associations between chronic exposure to PCBs and…
Aspergillosis in the middle ear of a harbour porpoise (Phocoena phocoena): A case report
Prahl, Susanne; Jepson, Paul D.; Sanchez-Hanke, Marcos; Deaville, Rob; Siebert, Ursula
Mycoses (2010)
Hearing is one of the major senses in whales and dolphins (cetaceans). This is the first report of severe mycotic otitis media in a cetacean, a juvenile female harbour porpoise…
Trace element concentrations, risks and their correlation with metallothionein genes polymorphism: A case study of narrow-ridged finless porpoises (Neophocaena asiaeorientalis) in the East China Sea
Liu, Jun; Chen, Bingyao; Jefferson, Thomas Allen; Wang, Hui; Yang, Guang
Science of the Total Environment (2016)
The concentration of trace elements (TEs) and their risk to narrow-ridged finless porpoises (Neophocaena asiaeorientalis) are still unclear. The present study determined the concentration of typical TEs in liver, kidney,…
Postglacial climate changes and rise of three ecotypes of harbour porpoises, Phocoena phocoena, in western Palearctic waters
Fontaine, Michaël C.; Roland, Kathleen; Calves, Isabelle; Austerlitz, Frederic; Palstra, Friso P.; Tolley, Krystal A.; Ryan, Sean; Ferreira, Marisa; Jauniaux, Thierry; Llavona, Angela; Öztürk, Bayram; Öztürk, Ayaka A.; Ridoux, Vincent; Rogan, Emer; Sequeira, Marina; Siebert, Ursula; Vikingsson, Gísli A.; Borrell, Asunción; Michaux, Johan R.; Aguilar, Alex
Molecular Ecology (2014)
Despite no obvious barriers to gene flow in the marine realm, environmental variation and ecological specializations can lead to genetic differentiation in highly mobile predators. Here, we investigated the genetic…
Toxoplasma gondii in stranded marine mammals from the North Sea and Eastern Atlantic Ocean: findings and diagnostic difficulties
van de Velde, Norbert; Devleesschauwer, Brecht; Leopold, Mardik; Begeman, Lineke; IJsseldijk, Lonneke; Hiemstra, Sjoukje; IJzer, Jooske; Brownlow, Andrew; Davison, Nicholas; Jauniaux, Thierry; Siebert, Ursula; Dorny, Pierre; De Craeye, Stéphane
Veterinary Parasitology (2016)
The occurrence of the zoonotic protozoan parasite Toxoplasma gondii in marine mammals remains a poorly understood phenomenon. In this study, samples from 631 marine mammal species and 34 European otters…
Spatially explicit analysis of genome-wide SNPs detects subtle population structure in a mobile marine mammal, the harbor porpoise
Lah, Ljerka; Trense, Daronja; Benke, Harald; Berggren, Per; Gunnlaugsson, Þorvaldur; Lockyer, Christina; Öztürk, Ayaka; Öztürk, Bayram; Pawliczka, Iwona; Roos, Anna; Siebert, Ursula; Skóra, Krzysztof; Víkingsson, Gísli; Tiedemann, Ralph
PLOS ONE (2016)
The population structure of the highly mobile marine mammal, the harbor porpoise (Phocoena phocoena), in the Atlantic shelf waters follows a pattern of significant isolation-by-distance. The population structure of harbor…
