Scientific Reports of the Whales Research Institute (1986)
(...) Makino (1948) studied chromosomes of a male P. dalli using traditional sectioning of testis tissue. Since it was generally accepted in those days that the two color morphs represent…
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…
Perinatal growth of delphinoids: Information from aquarium reared bottlenose dolphins and finless porpoises
Kasuya, T.; Tobayama, T.; Saiga, T.; Kataoka, T.
Scientific Reports of the Whales Research Institute (1986)
The early postnatal growth of bottlenose dolphins and finless porpoises was studied using 97 body length records of 61 individuals born in aquariums. The growth rates observed were similar to…
A review of the food habits of the small cetaceans of the Antarctic and sub-Antarctic
Goodall, R. N. P.; Galeazzi, A. R.
Antarctic Nutrient Cycles and Food Webs (1985)
This paper reviews the current state of knowledge of the food habits of the poorly known small cetaceans of the Southern Ocean and presents new information obtained through a study…
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…
Magnetoreception and biomineralization of magnetite in cetaceans
Bauer, G.B.; Fuller, M.; Perry, A.; Dunn, J.R.; Zoeger, J.
Magnetite Biomineralization and Magnetoreception in Organisms: A New Biomagnetism (1985)
(...) Although various sensory mechanisms are present in cetaceans, special navigational problems occur when animals are in a pelagic environment which can minimize available cues. Dawbin (1966) has observed that…
Growth of Dall’s porpoise in the western north Pacific and suggested geographical growth differentiation
Kasuya, T.; Shiraga, S.
Scientific Reports of the Whales Research Institute (1985)
Some growth parameters of the western North Pacific dalli-type Dall's porpoise were estimated from 167 specimens taken with hand-held harpoons on two cruises and compared with data obtained previously from…
The harbor porpoise, Phocoena phocoena, in Fish harbour, New Brunswick, Canada: Occupancy, distribution, and movements
Gaskin, D. E.; Watson, A. P.
Fishery Bulletin (1985)
The distribution, movements, and relative population abundance of harbor porpoises were studied in the Fish Harbour region of New Brunswick, Canada (lat. 44°59'30"-45°01'00"N, long. 66°54'00"-66°57'00"W), from 1970 to 1978. In…
