Using marine mammal necropsy data in animal health surveillance: The case of the harbor porpoise in the Southern North Sea

IJsseldijk, Lonneke L.; van den Broek, Jan; Kik, Marja J. L.; Leopold, Mardik F.; Bravo Rebolledo, Elisa; Gröne, Andrea; Heesterbeek, Hans
Frontiers in Marine Science (2024)

Rapid changes of marine ecosystems resulting from human activities and climate change, and the subsequent reported rise of infectious diseases in marine mammals, highlight the urgency for timely detection of…


Knowing the fishery to know the bycatch: Bias-corrected estimates of harbour porpoise bycatch in gillnet fisheries

Kindt-Larsen, Lotte; Glemarec, Gildas; Berg, Casper W.; Königson, Sara; Kroner, Anne-Mette; Søgaard, Mathias; Lusseau, David
Proceedings of the Royal Society B: Biological Sciences (2023)

Incidental captures (bycatch) remain a key global conservation threat for cetaceans. Bycatch of harbour porpoise Phocoena phocoena in set gillnets is routinely monitored in European Union fisheries, but generally relies…


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…


Harbor porpoise losing its edge: Genetic time series suggests a rapid population decline in Iberian waters over the last 30 years

Ben Chehida, Yacine; Stelwagen, Tjibbe; Hoekendijk, Jeroen P. A.; Ferreira, Marisa; Eira, Catarina; Torres‐Pereira, Andreia; Nicolau, Lidia; Thumloup, Julie; Fontaine, Michael C.
Ecology and Evolution (2023)

Impact of climate change is expected to be especially noticeable at the edges of a species' distribution, where they meet suboptimal habitat conditions. In Mauritania and Iberia, two genetically differentiated…


Out of sight, out of mind: How conservation is failing European porpoises

Carlén, Ida; Nunny, Laetitia; Simmonds, Mark P.
Frontiers in Marine Science (2021)

The conservation of harbor porpoises (Phocoena phocoena) appears to be failing in Europe. There are particular concerns about this species in the Baltic Proper, Black, and Mediterranean Seas, as well…


Evaluating management strategies for marine mammal populations: An example for multiple species and multiple fishing sectors in Iceland

Punt, André E; Siple, Margaret; Sigurðsson, Guðjón M.; Víkingsson, Gisli; Francis, Tessa B.; Granquist, Sandra Magdalena; Hammond, Philip S; Heinemann, Dennis; Long, Kristy J.; Moore, Jeffrey E.; Sepúlveda, Maritza; Reeves, Randall R.; Wade, Paul R.; Williams, Rob; Zerbini, Alexandre N.
Canadian Journal of Fisheries and Aquatic Sciences (2020)

A Management Strategy Evaluation is used to estimate success at achieving conservation goals for marine mammals while also aiming to minimize impacts on commercial fisheries. It is intended to improve…


Assessing the effects of banana pingers as a bycatch mitigation device for harbour porpoises (Phocoena phocoena)

Omeyer, Lucy C. M.; Doherty, Philip D.; Dolman, Sarah; Enever, Robert; Reese, Allan; Tregenza, Nicholas; Williams, Ruth; Godley, Brendan J.
Frontiers in Marine Science (2020)

Bycatch is a significant cause of population declines of marine megafauna globally. While numerous bycatch mitigation strategies exist, acoustic alarms, or pingers, are the most widely adopted strategy for small…
