Marine Pollution Bulletin (2023)

Shipping is the most pervasive source of marine noise pollution globally, yet its impact on sensitive fauna remains unclear. We tracked 10 harbour porpoises for 5–10 days to determine exposure…


Implications of porpoise echolocation and dive behaviour on passive acoustic monitoring

Macaulay, Jamie Donald John; Rojano-Doñate, Laia; Ladegaard, Michael; Tougaard, Jakob; Teilmann, Jonas; Marques, Tiago A.; Siebert, Ursula; Madsen, Peter Teglberg
The Journal of the Acoustical Society of America (2023)

Harbour porpoises are visually inconspicuous but highly soniferous echolocating marine predators that are regularly studied using passive acoustic monitoring (PAM). PAM can provide quality data on animal abundance, human impact,…


Diving on damage – The muscle transcriptome of parasitic infested harbor porpoises (Phocoena phocoena) hints at oxidative stress but not hypoxia

Dönmez, Eda Merve; Siebert, Ursula; Fabrizius, Andrej
Frontiers in Marine Science (2023)

The only native cetacean in German waters, the harbor porpoise (Phocoena phocoena), is impacted by numerous pathological lesions in the respiratory tract mainly caused by parasites or bacteria. Although harbor…


High rates of vessel noise disrupt foraging in wild harbour porpoises (Phocoena phocoena)

Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Siebert, Ursula; Galatius, Anders; Dietz, Rune; Madsen, Peter Teglberg
Proceedings of the Royal Society B: Biological Sciences (2018)

Shipping is the dominant marine anthropogenic noise source in the world's oceans, yet we know little about vessel encounter rates, exposure levels and behavioural reactions for cetaceans in the wild,…


Environmental drivers of harbour porpoise fine-scale movements

van Beest, Floris M.; Teilmann, Jonas; Dietz, Rune; Galatius, Anders; Mikkelsen, Lonnie; Stalder, Dominique; Sveegaard, Signe; Nabe-Nielsen, Jacob
Marine Biology (2018)

Quantifying intraspecific variation in movement behaviour of marine predators and the underlying environmental drivers is important to inform conservation management of protected species. Here, we provide the first empirical data…
