Mar Mam Sci (2014)
Life history parameters were determined for stranded and bycaught harbor porpoises (Phocoena phocoena) from Scottish (UK) waters (1992–2005). Fetal growth rate was 84.4 mm/mo and mean size at birth was…
Baltic Sea harbour porpoise populations: status and conservation needs derived from recent survey results
Benke, H.; Bräger, S.; Dähne, M.; Gallus, A.; Hansen, S.; Honnef, C. G.; Jabbusch, M.; Koblitz, J. C.; Krügel, K.; Liebschner, A.; Narberhaus, I.; Verfuß, U. K.
Marine Ecology Progress Series (2014)
During recent decades, the 2 distinct harbour porpoise populations of the Baltic Sea have decreased sharply in abundance. The Baltic Proper population is down to a few hundred individuals and…
Direct evidence for gray seal (Halichoerus grypus) predation and scavenging on harbor porpoises (Phocoena phocoena)
Bouveroux, Thibaut; Kiszka, Jeremy J.; Heithaus, Michael R.; Jauniaux, Thierry; Pezeril, Sylvain
Mar Mam Sci (2014)
(...) gray seal (Halichoerus grypus) consumption of harbor porpoises—whether predation or scavenging—might reflect a change in gray seal feeding habits in the southern North Sea (Haelters et al. 2012), where…
Effects of noise and by-catch on a Danish harbour porpoise population
Nabe-Nielsen, Jacob; Sibly, Richard M.; Tougaard, Jakob; Teilmann, Jonas; Sveegaard, Signe
Ecological Modelling (2014)
Ships and wind turbines generate noise, which can have a negative impact on marine mammal populations by scaring animals away. Effective modelling of how this affects the populations has to…
Genetic diversity and population structure of the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) as revealed by mitochondrial and microsatellite DNA
Chen, Minmin; Zheng, Jinsong; Wu, Min; Ruan, Rui; Zhao, Qingzhong; Wang, Ding
International Journal of Molecular Sciences (2014)
Ecological surveys have indicated that the population of the critically endangered Yangtze finless porpoise (YFP, Neophocaena asiaeorientalis asiaeorientalis) is becoming increasingly small and fragmented, and will be at high risk…
Do man-made structures and water depth affect the diel rhythms in click recordings of harbor porpoises (Phocoena phocoena)?
Brandt, Miriam J.; Hansen, Sophie; Diederichs, Ansgar; Nehls, Georg
Mar Mam Sci (2014)
The construction of industrial offshore structures may lead to colonization by a variety of marine organisms resulting in locally enhanced biodiversity and biomass, which may then affect the habitat use…
Cetaceans of the Moroccan coast: Information from a reconstructed strandings database
Masski, Hicham; De Stéphanis, Renaud
Journal of the Marine Biological Association of the United Kingdom (2015)
Cetaceans of Morocco have been poorly studied to date, and only sporadic information comes from scientific cruises for this group. In an attempt to learn more on the occurrence, distribution…
Behavioral responses of a harbor porpoise (Phocoena phocoena) to 25.5- to 24.5-kHz sonar down-sweeps with and without side bands
Kastelein, Ronald A.; van den Belt, Ivanka; Gransier, Robin; Johansson, Torbjörn
Aquatic Mammals (2015)
Signals used in naval and long-range fish detection sonar often contain harmonics which may influence the behavior of harbor porpoises (Phocoena phocoena) more than the lower fundamental frequencies, so the…
Assessing the impact of underwater clearance of unexploded ordnance on Harbour porpoises (Phocoena phocoena) in the southern North Sea
von Benda-Beckmann, Alexander M.; Aarts, Geert; Sertlek, H. Özkan; Lucke, Klaus; Verboom, Wim C.; Kastelein, Ronald A.; Ketten, Darlene R.; van Bemmelen, Rob; Lam, Frans-Peter A.; Kirkwood, Roger J.; Ainslie, Michael A.
Aquatic Mammals (2015)
Large amounts of legacy unexploded ordnance (UXO) are still present in the North Sea. UXO are frequently accidentally encountered by fishermen and dredging vessels. Out of concern for human safety…
Increased harbor porpoise mortality in the Pacific Northwest, USA: understanding when higher levels may be normal
Huggins, JL; Raverty, SA; Norman, SA; Calambokidis, J; Gaydos, JK; Duffield, DA; Lambourn, DM; Rice, JM; Hanson, B; Wilkinson, K; Jeffries, SJ; Norberg, B; Barre, L
Diseases of Aquatic Organisms (2015)
In 2006, a marked increase in harbor porpoise Phocoena phocoena strandings were reported in the Pacific Northwest of the USA, resulting in the declaration of an unusual mortality event (UME)…
