Cetacean monitoring is essential in determining the status of a population. Different monitoring methods should reflect the real trends in abundance and patterns in distribution, and results should therefore ideally…


Toxoplasma gondii in stranded marine mammals from the North Sea and Eastern Atlantic Ocean: findings and diagnostic difficulties

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…


Assessing auditory evoked potentials of wild harbor porpoises (Phocoena phocoena)

The Journal of the Acoustical Society of America (2016)

Testing the hearing abilities of marine mammals under water is a challenging task. Sample sizes are usually low, thus limiting the ability to generalize findings of susceptibility towards noise influences.…


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…
