The UK Government was recently criticised for failing to fulfil its obligations under the Habitats Directive in respect of designating protected areas for Harbour Porpoise Phocoena phocoena. At the centre…


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,…


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…


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…


After the bite: Bacterial transmission from grey seals (Halichoerus grypus) to harbour porpoises (Phocoena phocoena)

Gilbert, Maarten J.; IJsseldijk, Lonneke L.; Rubio-García, Ana; Gröne, Andrea; Duim, Birgitta; Rossen, John; Zomer, Aldert L.; Wagenaar, Jaap A.
Royal Society Open Science (2020)

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…


Determination of optimal acoustic passive reflectors to reduce bycatch of odontocetes in gillnets

Kratzer, Isabella M. F.; Schäfer, Ingo; Stoltenberg, Arne; Chladek, Jérôme C.; Kindt-Larsen, Lotte; Larsen, Finn; Stepputtis, Daniel
Frontiers in Marine Science (2020)

The need to minimize bycatch of toothed whales (odontocetes) in gillnets has long been recognized, because they are often top predators and thus essential to ecosystem resilience. It is likely…


Influence of anthropogenic activities on marine mammal strandings in the estuary and northwestern Gulf of St. Lawrence, Quebec, Canada, 1994–2008

Truchon, M.-H.; Measures, L.; Brêthes, J.-C.; Albert, É.; Michaud, R.
Journal of Cetacean Research and Management (2018)

Stranding records have long been used to monitor marine mammal mortalities and to help identify threats to populations. In coastal areas, marine mammals face numerous anthropogenic threats such as marine…
