Journal of Cetacean Research and Management (2017)
Until recently, little was known about the distribution and species occurrence of marine cetaceans in Pakistani waters, an area which needed to be addressed exigently given its inclusion in the…
Genetic footprint of population fragmentation and contemporary collapse in a freshwater cetacean
Chen, Minmin; Fontaine, Michael C.; Ben Chehida, Yacine; Zheng, Jinsong; Labbé, Frédéric; Mei, Zhigang; Hao, Yujiang; Wang, Kexiong; Wu, Min; Zhao, Qingzhong; Wang, Ding
Scientific Reports (2017)
Understanding demographic trends and patterns of gene flow in an endangered species is crucial for devising conservation strategies. Here, we examined the extent of population structure and recent evolution of…
High rates of vessel noise disrupt foraging in wild harbour porpoises (Phocoena phocoena)
Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Siebert, Ursula; Galatius, Anders; Dietz, Rune; Madsen, Peter Teglberg
Proceedings of the Royal Society B: Biological Sciences (2018)
Shipping is the dominant marine anthropogenic noise source in the world's oceans, yet we know little about vessel encounter rates, exposure levels and behavioural reactions for cetaceans in the wild,…
Water, water everywhere: Environmental DNA can unlock population structure in elusive marine species
Parsons, Kim M.; Everett, Meredith; Dahlheim, Marilyn; Park, Linda
Royal Society Open Science (2018)
Determining management units for natural populations is critical for effective conservation and management. However, collecting the requisite tissue samples for population genetic analyses remains the primary limiting factor for a…
Spatial and temporal baseline information on marine megafauna-data facilitated by a wildlife tour operator
de Boer, Marijke Nita; Jones, Duncan; Jones, Hannah; Knee, Rebecca
Open Journal of Marine Science (2018)
The protection of marine megafauna within Europe is rather fragmented. Developing conservation measures for highly mobile species presents definite challenges, particularly due to the many knowledge gaps. Recent studies have…
Food for thought: Harbor porpoise foraging behavior and diet inform vulnerability to disturbance
Booth, Cormac G.
Marine Mammal Science (2019)
Research has shown that noise disturbance can disrupt the behavior of harbor porpoises. The significance of such disturbance is unclear. However, these animals may be vulnerable to starvation when disturbed…
Response to “Resilience of harbor porpoises to anthropogenic disturbance: Must they really feed continuously?”
Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Rojano-Doñate, Laia; Shearer, Jeanne; Sveegaard, Signe; Miller, Lee A.; Siebert, Ursula; Madsen, Peter Teglberg
Marine Mammal Science (2017)
...There is, unfortunately, no unbiased way to assess the prey preference and dietary intake of free-ranging marine mammals like harbor porpoises. Although the traditional approach involving stomach content analysis of…
Resilience of harbor porpoises to anthropogenic disturbance: Must they really feed continuously?
Hoekendijk, Jeroen P. A.; Spitz, Jerome; Read, Andrew J.; Leopold, Mardik F.; Fontaine, Michael C.
Marine Mammal Science (2017)
...Recently, Wisniewska et al. (2016) used high-resolution digital acoustic tags (DTAGs) to monitor the foraging behavior of five harbor porpoises in Danish waters. This approach provided detailed observations on the…
Using pingers to reduce bycatch of small cetaceans in Peru’s small-scale driftnet fishery
Mangel, Jeffrey C.; Alfaro-Shigueto, Joanna; Witt, Matthew J.; Hodgson, David J.; Godley, Brendan J.
Oryx (2013)
There is growing awareness that small-scale fisheries may have large impacts on threatened marine fauna. Bycatch of small cetaceans by the Peruvian small-scale driftnet fleet results in the deaths of…
Pingers reduce the activity of Burmeister’s porpoise around small-scale gillnet vessels
Clay, T. A.; Alfaro-Shigueto, J.; Godley, B. J.; Tregenza, N.; Mangel, J. C.
Marine Ecology Progress Series (2019)
Incidental mortality (bycatch) in gillnet fisheries is a major threat to many cetacean populations. Acoustic alarms or pingers are a widely adopted management tool used to deter dolphins and porpoises…
