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…
Temporal changes in abundance of harbor porpoise (Phocoena phocoena) inhabiting the inland waters of Southeast Alaska
Dahlheim, Marilyn E.; Zerbini, Alexandre N.; Waite, Janice M.; Kennedy, Amy S.
Fishery Bulletin (2015)
Abundance of harbor porpoise (Phocoena phocoena) was estimated from data collected during vessel surveys conducted throughout the inland waters of Southeast Alaska. Line-transect methods were used during 18 seasonal surveys…
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…
Assessment of beach-cast cetaceans in Pakistan: Implications for conservation and management
Gore, M. A.; Culloch, R. M.; Gray, H. W. I.; Hoelzel, R.; Lockyer, C.; Kiani, M. S.; Waqas, U.; Hussain, B.; Rahim, A.; Shah, A.; Ormond, R. F. G.
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…
The bacterial diversity in infected tissue pus of an East Asian finless porpoise
Wu, Caiwen; Hong, Zhe; Ibrahim, Aamir; Zhang, Di; Wang, Lin; Li, Ting; Chen, Bingyao
African Journal of Microbiology Research (2019)
Two East Asian finless porpoises (Neophocaena asiaeorientalis sunameri) in Ningbo, East China Sea, China, were observed to be bacterially infected between the fat layer and muscle layer. The microbial communities…
Asymmetric and spiraled genitalia coevolve with unique lateralized mating behavior
Orbach, Dara N.; Brennan, Patricia L. R.; Hedrick, Brandon P.; Keener, William; Webber, Marc A.; Mesnick, Sarah L.
Scientific Reports (2020)
Asymmetric genitalia and lateralized mating behaviors occur in several taxa, yet whether asymmetric morphology in one sex correlates or coevolves with lateralized mating behavior in the other sex remains largely…
Forensic microbiology reveals that Neisseria animaloris infections in harbour porpoises follow traumatic injuries by grey seals
Foster, Geoffrey; Whatmore, Adrian M.; Dagleish, Mark P.; Malnick, Henry; Gilbert, Maarten J.; Begeman, Lineke; Macgregor, Shaheed K.; Davison, Nicholas J.; Roest, Hendrik Jan; Jepson, Paul; Howie, Fiona; Muchowski, Jakub; Brownlow, Andrew C.; Wagenaar, Jaap A.; Kik, Marja J. L.; Deaville, Rob; ten Doeschate, Mariel T. I.; Barley, Jason; Hunter, Laura; IJsseldijk, Lonneke L.
Scientific Reports (2019)
Neisseria animaloris is considered to be a commensal of the canine and feline oral cavities. It is able to cause systemic infections in animals as well as humans, usually after…
Click communication in wild harbour porpoises (Phocoena phocoena)
Sørensen, P. M.; Wisniewska, D. M.; Jensen, F. H.; Johnson, M.; Teilmann, J.; Madsen, P. T.
Scientific Reports (2018)
Social delphinids employ a vocal repertoire of clicks for echolocation and whistles for communication. Conversely, the less social and acoustically cryptic harbour porpoises (Phocoena phocoena) only produce narrow-band high-frequency (NBHF)…
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…
