Recent population growth of the harbour porpoise (Phocoena phocoena), grey seal (Halichoerus grypus) and common seal (Phoca vitulina) in the North Sea has increased potential interaction between these species. Grey…


Levels of polychlorinated biphenyls are still associated with toxic effects in harbor porpoises (Phocoena phocoena) despite having fallen below proposed toxicity thresholds

Williams, Rosie; ten Doeschate, Mariel; Curnick, David J.; Brownlow, Andrew; Barber, Jonathan L.; Davison, Nicholas J.; Deaville, Robert; Perkins, Matthew; Jepson, Paul D.; Jobling, Susan
Environmental Science & Technology (2020)

Polychlorinated biphenyls (PCBs) are toxic, persistent, and lipophilic chemical compounds that accumulate to high levels in harbor porpoises (Phocoena phocoena) and other cetaceans. It is important to monitor PCBs in…


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…


Mycotic infections in free-ranging harbor porpoises (Phocoena phocoena)

Kapetanou, Athanasia; IJsseldijk, Lonneke L.; Willems, Dorien S.; Broens, Els M.; Everaarts, Eligius; Buil, Jochem B.; Verweij, Paul E.; Kik, Marja J. L.; Gröne, Andrea
Frontiers in Marine Science (2020)

Studies on the occurrence of fungal communities in the marine environment are still scarce, but mycotic infections in cetaceans are increasingly reported. Fungal disease following infection with Aspergillus species is…


Modelling fine-scale distribution and relative abundance of harbour porpoises in the Southern Bight of the North Sea using platform-of-opportunity data

Bouveroux, Thibaut; Waggitt, James J.; Belhadjer, Anissa; Cazenave, Pierre W.; Evans, Peter G.H.; Kiszka, Jeremy J.
Journal of the Marine Biological Association of the United Kingdom (2020)

Over the last 25 years, the harbour porpoise (Phocoena phocoena) has made a significant return to the Southern Bight of the North Sea and the English Channel due to a…


Using passive acoustic monitoring to investigate the occurrence of cetaceans in a protected marine area in northwest Ireland

Todd, Nicole R. E.; Cronin, Michelle; Luck, Cian; Bennison, Ashley; Jessopp, Mark; Kavanagh, Ailbhe S.
Estuarine, Coastal and Shelf Science (2020)

Under the EU Habitats Directive, cetacean species must be maintained at favourable conservation status in European waters. Whether this is achieved via protected area designation, curtailment of activities such as…


High resolution three-dimensional beam radiation pattern of harbour porpoise clicks with implications for passive acoustic monitoring

Macaulay, Jamie D. J.; Malinka, Chloe E.; Gillespie, Douglas; Madsen, Peter T.
The Journal of the Acoustical Society of America (2020)

The source properties and radiation patterns of animal vocalisations define, along with propagation and noise conditions, the active space in which these vocalisations can be detected by conspecifics, predators, prey,…


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…
