Blood volumes, hemoglobin concentrations, packed-cell volumes, and heart weights were determined in three genera of porpoises which differ from one another in behavior and ecology. The estimate for the total…

The skull and incomplete skeleton of a specimen of Phocoena sinus from the Gulf of California are described and compared with specimens of P. phocoena and P. spinipinnis. The skeleton…
"Geographic variation of Burmeister's porpoise, Phocoena spinipinnis (Burmeister, 1865) (Cetacea: Phocoenidae), on the Atlantic and Pacific coasts of South America" (Thesis content in English) A total of 142 skulls from…
The site and physiologic mechanism(s) responsible for the generation of odontocete biosonar signals have eluded investigators for decades. To address these issues we subjected postmortem toothed whale heads to interrogation…
Highly significant (α = 0.01) differences in analysis of 473 skulls of harbour porpoises indicate separate eastern Pacific, western Atlantic, and eastern Atlantic populations. Including the isolated population in the…
The harbour porpoise (Phocoena phocoena) is subject to a high rate of incidental mortality in fisheries worldwide and, in some areas, these rates are sufficiently high to warrant concern over…
Tooth ultrastructure in harbour porpoise is examined as a possible tool for differentiating between animals from different geographical regions in the North Atlantic. Nine different characteristics in both dentine and…
The bycatch of harbour porpoise in the Danish North Sea bottom-set gillnet fisheries between 1987-2001 is estimated using two methods involving extrapolation of observer data. When observed entanglements are extrapolated…
The incidental catch of harbour porpoises (Phocoena phocoena) in the gillnet fishery of the Estuary and Gulf of St. Lawrence, Canada, was examined using: (1) questionnaires mailed to fishermen inquiring…
Using samples from bycaught finless porpoises, cytochrome b sequences were analysed and phylogenetic trees were constructed. The aims were to: (1) determine genetic divergences within the genus Neophocaena; (2) examine…
