Harbour porpoises are the most common small cetaceans in the North Sea and Dutch coastal waters. To study their trophic level and feeding location, stable carbon and nitrogen isotope ratios…
Harbour porpoise (Phocoena phocoena Linnaeus, 1758) entering the Weser river after decades of absence
Wenger, Denise; Koschinski, Sven
Marine Biology Research (2012)
Since 2005, harbour porpoise (Phocoena phocoena) sightings in the lower course of the river Weser have been reported after decades of apparent absence. The aim of this study was to…
Feeding habits and consumption by finless porpoises (Neophocaena asiaeorientalis) in the Yellow Sea
Park, Kyum-Joon; An, Yong-Rock; Lee, Young-Ran; Park, Ji-Eun; Moon, Dae-Yeon; Choi, Seok-Gwan
Korean Journal of Fisheries and Aquatic Sciences (2011)
We investigated the stomach contents of finless porpoises collected in the Yellow Sea. Prey organisms in the stomachs of 109 finless porpoises were identified as 11 species of fish, 8…
Geographic variation of skeletal ontogeny and skull shape in the harbour porpoise (Phocoena phocoena)
Galatius, A.; Gol’din, P. E.
Canadian Journal of Zoology (2011)
All extant porpoise species show paedomorphic skeletal traits. These traits are hypothesized to be connected with rapid growth to reproductive size and could thus show geographic variation according to ecological…
Harbor porpoise observations in Burrows Pass, December 2009 through December 2010
Jeffries, A.
(2011)
Pacific Biodiversity Institute (PBI) initiated a study of the harbor porpoise in the Puget Sound in 2007. One of the early outcomes of this study was to identify an area,…
Spatial and temporal distribution of harbour porpoises in relation to their prey
Sveegaard, S.
Doctoral Thesis - Aarhus Universitet (2011)
The population status of harbour porpoises has been of concern for several years due to anthropogenic influences, especially incidental bycatch in gillnet fisheries. Proper management of a wide-ranging species such…
Isotopic assessment of prey and habitat preferences of a cetacean community in the southwestern South Atlantic Ocean
Riccialdelli, L.; Newsome, S. D.; Fogel, M. L.; Goodall, R. N. P.
Marine Ecology Progress Series (2010)
We used stable carbon (δ13 C) and nitrogen (δ15 N) isotope analysis to investigate the trophic ecology of 8 small cetacean species of the southwestern South Atlantic Ocean: 6 delphinids…
Prey capture by harbor porpoises (Phocoena phocoena): A comparison between echolocators in the field and in captivity
Miller, L.A.
The Journal of the Marine Acoustics Society of Japan (2010)
The harbor porpoise, and other toothed whales, use a biosonar click sequence that resembles the sequence of cries used by insectivorous bats when hunting for and capturing prey. The temporal…
Paedomorphosis in two small species of toothed whales (Odontoceti): How and why?
Galatius, Anders
Biological Journal of the Linnean Society (2010)
To evaluate and assess the ontogenetic background for paedomorphosis in phocoenids, samples of 144 harbour porpoises, 81 white-beaked dolphins, and 130 Commerson's dolphins were compared in terms of the development…
Habitat preferences and interannual variability in occurrence of the harbour porpoise Phocoena phocoena off northwest Scotland
Marubini, F.; Gimona, A.; Evans, P. G. H.; Wright, P. J.; Pierce, G. J.
Marine Ecology Progress Series (2009)
The harbour porpoise Phocoena phocoena is the most common cetacean around the British Isles, but knowledge of its ecology, habitat preferences and inter-annual variability is still inadequate. Here, sightings collected…
