Marine Mammal Sci (1997)
The ability of a finless porpoise (Neophocaena phocaenoides) to discriminate the material and size of a target by echolocation was investigated. The porpoise was required to choose a standard target…

First estimates of vaquita abundance
Barlow, Jay; Gerrodette, Tim; Silber, Greg
Marine Mammal Sci (1997)
The abundance of the only population of vaquitas, Gulf of California harbor porpoise (Phocoena sinus), is estimated from four surveys conducted in Mexico between 1986 and 1993, using a variety…
Geographical variation in metric skull characters among proposed subpopulations and stocks of harbor porpoise, Phocoena phocoena, in the western north Atlantic
Gao, Anli; Gaskin, D. E.
Marine Mammal Science (1996)
A total of 433 skulls of harbor porpoises, Phocoena phocoena, were examined to evaluate geographical variation within the western North Atlantic, using analysis of covariance and discriminant analysis based on…
Summer feeding habits of Dall’s porpoise, Phocoenoides dalli, in the southern Sea of Okhotsk
Walker, William A.
Marine Mammal Sci (1996)
Stomach contents were analyzed from 85 Dall's porpoises, Phocoenoides dalli, taken in the southern Sea of Okhotsk during the summer of 1988. Thirteen species of fish and five species of…
Blood chemistry of wild harbor porpoises Phocoena phocoena (L.)
Koopman, H. N.; Westgate, A. J.; Read, A. J.; Gaskin, D. E.
Marine Mammal Sci (1995)
Blood chemistry values were measured from 31 harbor porpoises (Phocoena phocoena) released from herring weirs in the Bay of Fundy, Canada. Sodium, phosphorus, calcium, chloride, magnesium, total protein, albumin, globulin,…
Insufficient data are available to predict the success of protected areas for the vaquita (Phocoena sinus): A critique of Gerrodette and Rojas-Bracho (2011)
Lonergan, Mike
Marine Mammal Science (2012)
(...) Gerrodette and Rojas-Bracho (2011) fit a quite detailed Bayesian model to sparse data on vaquita (Phocoena sinus) abundance in order to investigate the likely effects of different degrees of…
Inference from limited data: A response to Lonergan
Gerrodette, Tim; Rojas-Bracho, Lorenzo
Marine Mammal Science (2012)
(...) Lonergan (2012) criticized the analysis of Gerrodette and Rojas-Bracho (2011), who estimated the success of three possible protected areas for the critically endangered vaquita (Phocoena sinus) proposed under the…
Analysis of the artisanal fisheries of San Felipe, Mexico: Estimating incidental mortality of the vaquita (Phocoena sinus)
Urrutia-Osorio, M. Fernanda; Jaramillo-Legorreta, Armando M.; Rojas-Bracho, Lorenzo; Sosa-Nishizaki, Oscar
Journal of Marine Animals and Their Ecology (2015)
The vaquita (Phocoena sinus) is the most critically endangered cetacean species in the world and is a small porpoise endemic to the northern Gulf of California, Mexico. As fishing efforts…
Geographical variation of the parasite, Phyllobothrium delphini (Cestoda), in Dall’s porpoise, Phocoenoides dalli, in the northern north Pacific, Bering Sea, and Sea of Okhotsk
Walker, William A.
Marine Mammal Sci (2001)
Prevalence of the larval cestode, Phyllobothrium delphini, was estimated from 2,445 Dall's porpoise, Phocoenoides dalli, from the incidental take of the Japanese high seas salmon drift-net fishery in the northwestern…
