Fishery Bulletin (1988)
We conducted aerial surveys in September 1984 and September and October 1985 to determine the abundance of harbor porpoise along the coasts of California, Oregon, and Washington. Two observers and…
Genetic variability and differentiation in the toothed whales
Shimura, E.; Numachi, K.-I.
Scientific Reports of the Whales Research Institute (1987)
Genetic variability and differentiation of three families containing 12 species of toothed whales mainly from the sea around Japan have been examined by starch-gel electrophoresis at 19 genetic loci encoding…
Morphometric and meristic comparisons of skulls of harbour porpoise Phocoena phocoena (L.) from the North Atlantic and North Pacific
Yurick, Douglas B.; Gaskin, David. E.
Ophelia (1987)
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…
Note on the occurrence of Spondylitis deformans in a sample of harbour porpoises (Phocoena phocoena (L.)) taken in Danish waters
Kinze, C. C.
Aquatic Mammals (1986)
(...) Spondolytis deformans, a pathological deformation of the vertebral column, has so far been found in 41 cases in 26 recent and extinct cetacean species, among them the harbour porpoise…
Topographic distribution of sizes and density of ganglion cells in the retina of a porpoise, Phocoena phocoena
Mass, A. M.; Supin, A. Ya.; Severtsov, A. N.
Aquatic Mammals (1986)
(...) Dolphins are well-known for their developed hearing and echolocation systems. However, data on the organization of other sensory systems in these animals are limited. Namely, the organization of the…
A review of human impact on small cetaceans
Northridge, S.; Pilleri, G.
Investigations on Cetacea (1986)
(...) This document attempts to gather together as much information as is available on the extent of current killings of small cetaceans throughout the world, and also to highlight some…
Ontogenetic development of the nervus terminalis in toothed whales
Buhl, E. H.; Oelschläger, H. A.
Anatomy and Embryology (1986)
For the first time in cetaceans, the development of the terminalis system and its continuity between the olfactory placode and the telencephalon has been demonstrated by light microscopy. In the…
Energy budget of a small cetacean, the harbour porpoise, Phocoena phocoena (L.)
Yasui, W. Y.; Gaskin, D. E.
Ophelia (1986)
The objective of this study was to assemble the components of an energy budget for the harbour porpoise in the western Bay of Fundy, Canada. The annual energetic requirements for…
Evolution, taxonomy and antitropical distributions of the porpoises (Phocoenidae, Mammalia)
Barnes, Lawrence G.
Marine Mammal Sci (1985)
True porpoises are a morphologically distinctive and evolutionarily old group of odontocete cetaceans classified as the family Phocoenidae. They are distinct from members of the family Delphinidae, with which they…
Development and rudimentation of the peripheral olfactory system in the harbor porpoise, Phocoena phocoena (Mammalia: Cetacea)
Oelschläger, Helmut A.; Buhl, Eberhard H.
Journal of Morphology (1985)
Serial sections of 13 embryos and fetuses of the harbor porpoise from 10 mm crown-rump length up to 167 mm total length were studied. Unlike the adult animals, ontogenetic stages…
