This study investigated how skin contributes to buoyancy control in the Florida manatee (Trichechus manatus latirostris), harbor porpoise (Phocoena phocoena), and bottlenose dolphin (Tursiops truncatus). Manatees are shallow divers and…
Irrawaddy dolphins Orcaella brevirostris and finless porpoises Neophocaena phocaenoides are referred to as facultative freshwater cetaceans because they occupy both fresh- and nearshore marine waters. In Asia, the especially rapid…
We describe an experiment conducted to assess the impact of the sound generated by an acoustic harassment device (AHD) on the relative abundance and distribution of harbor porpoises (Phocoena phocoena)…
A system for automatically detecting the vocalisations of Harbour Porpoises Phocoena phocoena is described. The system consists of a high frequency hydrophone, an analogue electronics module and software running on…
From 5 March to 1 July, 1999 and 2000, we made six shipboard surveys for finless porpoises (Neophocaena phocaenoides) in the Inland Sea, which is believed to be inhabited by…
We measured metric and scored non-metric characters of 242 harbour porpoise (Phocoena phocoena) skulls from the North and the Baltic Sea and subdivided them into three geographical areas: The German…
Fifteen fishing centres on the northern and central coasts of Peru, including large industrial fishing ports and smaller fish landing sites were surveyed for cetacean landings periodically over 29 months,…
Between the years 1990 and 2000, an attempt was made to determine the causes of death of 55 harbour porpoises stranded along the Belgian and northern French coasts. From 1990…
The status of small cetaceans in the North Sea and adjacent waters has been of concern for many years. Shipboard and aerial line transect surveys were conducted to provide accurate…
Concern about the conservation and management of harbour porpoise (Phocoena phocoena) populations, which have experienced relatively large incidental fishery kills in localised areas throughout their range, has prompted research to…
