Seabed pockmarks are among the most prominent morphologic structures in the oceans. They are usually interpreted as surface manifestation of hydrocarbon fluids venting from sediments. Here we suggest an alternative…

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…

Evolutionary history and seascape genomics of harbour porpoises (Phocoena phocoena) across environmental gradients in the North Atlantic and adjacent waters

Ecological Modelling (2023)

The Yangtze finless porpoise (Neophocaena asiaeorientalis) is critically endangered. Finless porpoises rely on small fish as their primary food source. Fish distribution is impacted by topography and vorticity (i.e., water…

Recent progress and future directions for conservation of the Yangtze finless porpoise (Neophocaena asiaorientalis asiaorientalis)

With the functional extinction of the Yangtze River dolphin or baiji (Lipotes vexillifer) based on the survey conducted in 2006, the Yangtze finless porpoise (Neophocaena asiaorientalis) is now the only…

Harassment and killing of porpoises (“phocoenacide”) by fish‐eating Southern Resident killer whales (Orcinus orca)
