Small boat surveys were conducted in the Kuching Bay area of Sarawak, East Malaysia, in order to determine the distribution and abundance of coastal cetaceans. Photographic data collected from Jul.…
The stranding anomaly as population indicator: The case of harbour porpoise Phocoena phocoena in north-western Europe
Peltier, Helene; Baagøe, Hans J.; Camphuysen, Kees C. J.; Czeck, Richard; Dabin, Willy; Daniel, Pierre; Deaville, Rob; Haelters, Jan; Jauniaux, Thierry; Jensen, Lasse F.; Jepson, Paul D.; Keijl, Guido O.; Siebert, Ursula; Van Canneyt, Olivier; Ridoux, Vincent
PLoS ONE (2013)
Ecological indicators for monitoring strategies are expected to combine three major characteristics: ecological significance, statistical credibility, and cost-effectiveness. Strategies based on stranding networks rank highly in cost-effectiveness, but their ecological…
Predictions from harbor porpoise habitat association models are confirmed by long-term passive acoustic monitoring
Brookes, Kate L.; Bailey, Helen; Thompson, Paul M.
The Journal of the Acoustical Society of America (2013)
Survey based habitat association models provide good spatial coverage, but only a snapshot in time of a species' occurrence in a particular area. A habitat association model for harbor porpoises…
Habitat preferences and distribution of the harbour porpoise Phocoena phocoena west of Scotland
Booth, C. G.; Embling, C.; Gordon, J.; Calderan, S. V.; Hammond, P. S.
Marine Ecology Progress Series (2013)
The west coast of Scotland is comprised of complex coastlines and topography, and a range of physical processes influence its coastal marine environment. The region is host to one of…

Journal of the Marine Biological Association of the United Kingdom (2013)
The Istanbul Strait (Bosphorus) is a part of the Turkish Straits System, connecting the Aegean Sea and the Black Sea. There are three cetacean species in the Strait, namely the…
Cetacean distribution and abundance in relation to oceanographic domains on the eastern Bering Sea shelf, June and July of 2002, 2008, and 2010
Friday, Nancy A.; Zerbini, Alexandre N.; Waite, Janice M.; Moore, Sue E.; Clapham, Phillip J.
Deep Sea Research Part II: Topical Studies in Oceanography (2013)
As part of the Bering Sea Project, cetacean surveys were conducted to describe distribution and estimate abundance on the eastern Bering Sea shelf. Three marine mammal observers conducted visual surveys…
The possible reasons for bottlenose dolphins (Tursiops truncatus) participating in non-predatory aggressive interactions with harbour porpoises (Phocoena phocoena) in Cardigan Bay, Wales
Neale, Leonora
Honour's Thesis - University of Nottingham (2013)
Between 1991 and 2011, 137 harbour porpoises (Phocoena phocoena) died as a result of attacks by bottlenose dolphins (Tursiops truncatus) in Cardigan Bay. The suggested reasons for these non-predatory aggressive…
Spatial interactions between marine predators and their prey: Herring abundance as a driver for the distributions of mackerel and harbour porpoise
Sveegaard, S.; Nabe-Nielsen, J.; Stæhr, K. J.; Jensen, T. F.; Mouritsen, K. N.; Teilmann, J.
Marine Ecology Progress Series (2012)
The distribution of marine predators is tightly coupled with that of their prey, and may also be affected by interactions between competing predators. In order to adopt an ecosystem approach…
Seasonal changes in the local distribution of Yangtze finless porpoises related to fish presence
Kimura, Satoko; Akamatsu, Tomonari; Li, Songhai; Dong, Lijun; Wang, Kexiong; Wang, Ding; Arai, Nobuaki
Marine Mammal Science (2011)
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is an endangered freshwater porpoise subspecies unique to the Yangtze River basin. Seasonal variations in local distribution of the animal, as well as…
Revision of the taxonomy of finless porpoises (genus Neophocaena): the existence of two species
Jefferson, Thomas A.; Wang, John Y.
Journal of Marine Animals and Their Ecology (2011)
Due to extensive morphological variation and inadequately-sampled or poorly-designed studies, the taxonomy of the finless porpoises (genus Neophocaena) has been controversial for some time. An uneasy stability with the arrangement…
