Journal of Experimental Biology (2006)
An experiment was conducted to investigate the sound pressure patterns on the melon of odontocetes by using four broadband hydrophones embedded in suction cups to measure echolocation signals on the…
Harbour porpoises (Phocoena phocoena) in the North Atlantic: Distribution and genetic population structure
Andersen, Liselotte Wesley
NAMMCOSP (2003)
The known geographical distribution (based on ship surveys, aerial surveys, incidental sightings, stranding and bycatch data) and the population genetic structure obtained from mitochondria DNA and nuclear DNA (isozymes and…
Comparison of echolocation behaviour between coastal and riverine porpoises
Akamatsu, Tomonari; Teilmann, Jonas; Miller, Lee A.; Tougaard, Jakob; Dietz, Rune; Wang, Ding; Wang, Kexiong; Siebert, Ursula; Naito, Yasuhiko
Deep Sea Research Part II: Topical Studies in Oceanography (2007)
Echolocation behaviour of a harbor porpoise and six finless porpoises was recorded in open-water systems using acoustic data loggers (A-tag). In total 1359 click trains were recorded during 4.6 h…
Phylogeography of the finless porpoise (genus Neophocaena): testing the stepwise divergence hypothesis in the northwestern Pacific
Lin, Wenzhi; Frère, Céline H.; Karczmarski, Leszek; Xia, Jia; Gui, Duan; Wu, Yuping
Scientific Reports (2014)
We used 344 mitochondrial control region (717 bp) sequences from the finless porpoise (genus Neophocaena) from the northwestern Pacific to investigate the extent and manner in which past climatic oscillations may…
Abundance estimate of finless porpoises off the Pacific coast of eastern Japan based on aerial surveys.
Amano, Masao; Nakahara, Fumio; Hayano, Azusa; Shirakihara, Kunio
Mammal Study (2003)
We carried out an aerial survey to estimate the abundance of finless porpoises Neophocaena phocaenoides off the Pacific coast of eastern Japan between Sendai Bay (38°23’N) and the mouth of…
Vaquitas and gillnets: Mexico’s ultimate cetacean conservation challenge
Rojas-Bracho, L; Reeves, RR
Endangered Species Research (2013)
There is a high risk that incidental mortality (bycatch) in gillnets will lead to extinction of the vaquita Phocoena sinus, a small porpoise endemic to Mexico’s northern Gulf of California.…
Use of organochlorines as chemical tracers in determining some reproductive parameters in Dalli-type Dall’s porpoise Phocoenoides dalli
Subramanian, AN.; Tanabe, Shinsuke; Tatsukawa, Ryo
Marine Environmental Research (1988)
Persistent organochlorines (PCBs and p,p′-DDE) in the bodies of dalli- and truei-type Dall's porpoises (Phocoenoides dalli) from the Bering Sea and the northwestern North Pacific were used as chemical tracers…
Potential limits to anthropogenic mortality of small cetaceans in coastal waters of British Columbia
Williams, Rob; Hall, Anna; Winship, Arliss
Can. J. Fish. Aquat. Sci. (2008)
Small cetaceans are by-caught in salmon gillnet fisheries in British Columbia (BC) waters. In Canada, there is currently no generic calculation to identify when management action is necessary to reduce…
Temporal changes in abundance of harbor porpoise (Phocoena phocoena) inhabiting the inland waters of Southeast Alaska
Dahlheim, Marilyn E.; Zerbini, Alexandre N.; Waite, Janice M.; Kennedy, Amy S.
Fishery Bulletin (2015)
Abundance of harbor porpoise (Phocoena phocoena) was estimated from data collected during vessel surveys conducted throughout the inland waters of Southeast Alaska. Line-transect methods were used during 18 seasonal surveys…

LORENZO ROJAS-BRACHO; RANDALL R. REEVES; ARMANDO JARAMILLO-LEGORRETA
Mammal Review (2006)
The vaquita Phocoena sinus is a small porpoise that is endemic to the northern Gulf of California, Mexico. It is the most critically endangered marine small cetacean in the world.…
