Offshore Wind Energy (2005)
The harbour, or common, porpoise (Phocoena phocoena) is the smallest cetacean inhabiting temperate to cold waters throughout the northern hemisphere. Due to its occurrence mainly but not exclusively in coastal…
Diel variation in echolocation behavior of wild harbor porpoises
Carlstrom, Julia
Marine Mammal Science (2005)
The echolocation rate and behavior of wild harbor porpoises were studied using a harbor porpoise click detector (POD) deployed close to the bottom at 40 m depth in Scottish waters,…
Population genetic structure of the Yangtze Finless Porpoise (Neophocaena phocaenoides asiaeorientalis): Implications for management and conservation
Zheng, Jin-Song; Xia, Jun-Hong; He, Shun-Ping; Wang, Ding
Biochem Genet (2005)
Understanding the population genetic structure is a prerequisite for conservation of a species. The degree of genetic variability characteristic of the mitochondrial DNA control region has been widely exploited in…
Sexually dimorphic proportions of the harbour porpoise (Phocoena phocoena) skeleton
Galatius, Anders
Journal of Anatomy (2005)
Sexual differences in growth, allometric growth patterns and skeletal proportions were investigated by linear measurements of skeletal parts on 225 harbour porpoises (Phocoena phocoena) from the inner Danish and adjacent…
A review of acoustic surveys and conservations actions for the vaquita
JARAMILLO-LEGORRETA, A.; ROJAS-BRACHO, L.; URBAN, J.
Scientific Committee Meeting Documents (2005)
In the first part of this report we present our results, so far, derived from the application of passive acoustic techniques to study the habitat use of vaquita. In the…
Polybrominated diphenyl ethers (PBDEs) and organochlorines in small cetaceans from Hong Kong waters: Levels, profiles and distribution
Ramu, Karri; Kajiwara, Natsuko; Tanabe, Shinsuke; Lam, Paul K.S.; Jefferson, Thomas A.
Marine Pollution Bulletin (2005)
Polybrominated diphenyl ethers (PBDEs) and organochlorine compounds (OCs) were determined in the blubber, liver and kidney of Indo-Pacific humpback dolphins (Sousa chinensis) and finless porpoises (Neophocaena phocaenoides) stranded in Hong…
Receiving beam patterns in the horizontal plane of a harbor porpoise (Phocoena phocoena)
Kastelein, Ronald A.; Janssen, Mirjam; Verboom, Willem C.; de Haan, Dick
The Journal of the Acoustical Society of America (2005)
Receiving beam patterns of a harbor porpoise were measured in the horizontal plane, using narrow-band frequency modulated signals with center frequencies of 16, 64, and 100kHz. Total signal duration was…
Spatial orientation in echolocating harbour porpoises (Phocoena phocoena)
Verfuss, U. K.
Journal of Experimental Biology (2005)
Studies concerning the echolocation behaviour of odontocetes focus mainly on target detection and discrimination, either in stationary animals or in animals approaching a specific target. We present the first data…
Relative abundance of harbour porpoises (Phocoena phocoena) from acoustic and visual surveys of the Baltic Sea and adjacent waters during 2001 and 2002
Gillespie, D.; Berggren, P.; Brown, S.; Kuklik, I.; Lacey, C.; Lewis, T.; Matthews, J.; McLanaghan, R.; Moscrop, A.; Tregenza, N.
Journal of Cetacean Research and Management (2005)
Boat-based acoustic and visual surveys for harbour porpoises (Phocoena phocoena) were conducted during the summers of 2001 and 2002 in order to investigate their distribution and relative abundance in the…
The first Yangtze finless porpoise successfully born in captivity
WANG, Ding; HAO, Yujiang; WANG, Kexiong; ZHAO, Quingzhong; CHEN, Daoquang; WEI, Zhuo; ZHANG, Xianfeng
Environmental Science and Pollution Research (2005)
As the sole freshwater subspecies of finless porpoise (Neophocaena phocaenoides), the Yangtze finless porpoise (N. p. asiaeorientalis) lives only in the middle and lower reaches of the Yangtze River and…
