(...) Some of the observations mentioned in this paper have been made at sea, on board the oceanographic vessel Calypso, put at our disposal by a special committee of the…
Several studies have shown that pingers mitigate porpoise bycatch and thus pinger use is now mandatory in some fisheries—although the long-term effects of pinger exposure on porpoises have not been…
This report was requested by Elsam Engineering A/S. It consists of a summary of results obtained in 2004 from the ongoing monitoring program of harbour porpoises in and around Horns…
Information on the habitat use of the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is critical for its conservation. The diel biosonar behavior of the porpoise in the port…
Boat-based acoustic and visual surveys for harbour porpoises (Phocoena phocoena) were conducted during the summers of 2001 and 2002 in order to investigate their distribution and relative abundance in the…
1. Robust estimates of the density or abundance of cetaceans are required to support a wide range of ecological studies and inform management decisions. Considerable effort has been put into…
The distribution of harbour porpoises Phocoena phocoena in southern Europe and along the Atlantic African coast is poorly understood, with tentative assessments suggesting a discrete West African population with a…
Since 2005, harbour porpoise (Phocoena phocoena) sightings in the lower course of the river Weser have been reported after decades of apparent absence. The aim of this study was to…
Harbour porpoise signals consist of directional, high frequency stereotypic clicks which can be logged using T-PODs. Variation in interclick intervals (ICIs) can be used to distinguish different acoustic behaviours. So…
