Investigations on Cetacea (1969)
Among captive harbour porpoises, Phocaena phocaena (L.) epimeletic behaviour has been observed. Nurturant behaviour was performed by a juvenile female and a juvenile male toward sucklings and evidence is given…

An audiogram has been obtained from the harbour porpoise, Ph.phocoena, in water from 1 to 150 kHz by using the operant conditioning technique. The highest sensitivity was measured between 8…
This paper is a contribution to the knowledge of the marine and estuarine cetacean fauna of Pakistani waters and it is based on the investigation of our own material collected…
Two harbour porpoises, a male and a female, both around 10 months old, which had to be left alone for periods between bio-acoustical investigations, developed stereotyped motor patterns and signs…

A pilot study has been carried out in order to obtain information on the observational problems encountered in studying the harbour porpoise (Phocoena phocoena) in the wild. It is concluded…
This study confirms earlier observations of apparently involuntary movements, strongly associated with the breathing. The movements include taxes - a dorsal flexure of the thorax and steering movements with the…

Six harbor porpoises captured in herring weirs between September 1973 and September 1974 on the southern coast of New Brunswick were tagged and released. The three smallest animals were given…
(...) Studies on the biology and ecology of the species [harbour porpoise] by the University of Guelph, largely sponsored by the National Research Council of Canada, were begun in the…
