Theriogenology (2019)
Knowledge about reproductive parameters in male harbour porpoises such as testicular histology and germ cell maturation as well as seasonal changes in spermatogenesis is scarce. Thus, the aim of the…
Crossing boundaries for cetacean conservation: Setting research priorities to guide management of harbour porpoises
IJsseldijk, Lonneke L.; ten Doeschate, Mariel T. I.; Davison, Nicholas J.; Gröne, Andrea; Brownlow, Andrew C.
Marine Policy (2018)
Effective management of natural resources involves a multidisciplinary perspective to address complex issues in data poor-environments. With mobile species that do not conform to human-defined borders a cross-boundary approach is…
Silent porpoise: Potential sleeping behaviour identified in wild harbour porpoises
Wright, Andrew J.; Akamatsu, Tomonari; Mouritsen, Kim N.; Sveegaard, Signe; Dietz, Rune; Teilmann, Jonas
Animal Behaviour (2017)
All animals sleep and it is essential for maintaining optimal brain function. However, cetaceans engage in the unusual practice of unihemispherical sleep, where only half of their brain sleeps at…

Biological Conservation (2018)
Knowledge on spatial and seasonal distribution of species is crucial when designing protected areas and implementing management actions. The Baltic Proper harbour porpoise (Phocoena phocoena) population is critically endangered, and…
Juvenile harbor porpoises in the UK are exposed to a more neurotoxic mixture of polychlorinated biphenyls than adults
Williams, Rosie S.; Curnick, David J.; Barber, Jonathan L.; Brownlow, Andrew; Davison, Nicholas J.; Deaville, Rob; Perkins, Matthew; Jobling, Susan; Jepson, Paul D.
Science of The Total Environment (2020)
Polychlorinated biphenyls (PCBs) are a group of 209 persistent and bio-accumulative toxic pollutants present as complex mixtures in human and animal tissues. Harbor porpoises accumulate some of the highest levels…

An adult male harbour porpoise (Phocoena phocoena) stranded off the coast of Alaska displaying poor body condition, scattered mild ulcerative dermatitis, and necrotizing balanoposthitis. Necropsy findings included severe verminous panniculitis,…
Spatial avoidance to experimental increase of intermittent and continuous sound in two captive harbour porpoises
Kok, Annebelle C. M.; Engelberts, J. Pamela; Kastelein, Ronald A.; Helder-Hoek, Lean; Van de Voorde, Shirley; Visser, Fleur; Slabbekoorn, Hans
Environmental Pollution (2018)
The continuing rise in underwater sound levels in the oceans leads to disturbance of marine life. It is thought that one of the main impacts of sound exposure is the…
