Virus Research (2019)
An adult male harbour porpoise (Phocoena phocoena) stranded off the coast of Alaska displaying poor body condition, scattered mild ulcerative dermatitis, and necrotizing balanoposthitis. Necropsy findings included severe verminous panniculitis,…
Saving the vaquita one bite at a time: The missing role of the shrimp consumer in vaquita conservation
Dunch, Victoria
Marine Pollution Bulletin (2019)
The vaquita (Phocoena sinus) is the world's smallest cetacean and most endangered marine mammal. The species is under threat from illegal fishing activities that take place in the upper Gulf…
Agonistic interactions and dominance relationships in three groups of captive odontocetes: Method of assessment and inter-species/group comparison
Serres, Agathe; Hao, Yujiang; Wang, Ding
Aquatic Mammals (2019)
Social group dynamics are known to impact odontocetes’ health and welfare in captivity. Social dominance and agonistic interactions that occur to establish and maintain these relationships might express themselves differently…
Comparison of co-deployed drifting passive acoustic monitoring tools at a high flow tidal site: C-PODs and IcListenHF hydrophones
Adams, M.; Sanderson, B.; Porskamp, P.; Redden, A.
The Journal of Ocean Technology (2019)
Porpoise click detectors (C-PODs) and icListenHF hydrophones that record with a high sample rate were deployed on a drifter in fast tidal currents in Minas Passage, Bay of Fundy, on…
Differential population dynamics of a coastal porpoise correspond to the fishing effort in a large estuarine system
Lin, Wenzhi; Karczmarski, Leszek; Li, Jun; Chan, Stephen C. Y.; Guo, Lang; Wu, Yuping
Aquatic Conservation: Marine and Freshwater Ecosystems (2019)
The finless porpoise (genus Neophocaena) is susceptible to fishery‐caused mortality, and its numbers are thought to be in decline across its entire range. However, population demographics have rarely been quantified…
Context-dependent biosonar adjustments during active target approaches in echolocating harbour porpoises
Ladegaard, Michael; Madsen, Peter Teglberg
The Journal of Experimental Biology (2019)
Echolocating mammals generally target individual prey items by transitioning through the biosonar phases of search (slow-rate, high-amplitude outputs), approach (gradually increasing rate and decreasing output amplitude) and buzzing (high-rate, low-amplitude…
Testicular morphology and spermatogenesis in harbour porpoises (Phocoena phocoena)
Kesselring, T.; Viquerat, S.; IJsseldijk, L. L.; Langeheine, M.; Wohlsein, P.; Gröne, A.; Bergmann, M.; Siebert, U.; Brehm, R.
Theriogenology (2019)
Knowledge about reproductive parameters in male harbour porpoises such as testicular histology and germ cell maturation as well as seasonal changes in spermatogenesis is scarce. Thus, the aim of the…
