To clarify population structure of finless porpoises (Neophocaena phocaenoides) in Japan, a sequence of studies have been conducted: a questionnaire survey and aerial sighting surveys to obtain information on porpoise…
North Atlantic harbour porpoises Phocoena phocoena (L.) face considerable energetic challenges, as they are relatively small marine mammals with an intense reproductive schedule and a cold-water habitat. Post-natal growth of…
The northernmost records of four cold-water cetacean species in the southwestern Atlantic are presented: the spectacled porpoise (Phocoena dioptrica), Layard's beaked whale (Mesoplodon layardii), Commerson's dolphin (Cephalorhynchus commersonii), and Peale's…
Seven hundred and twenty base pairs (bp) of the mitochondrial control region from 73 finless porpoises, Neophocaena phocaenoides, in Chinese waters were sequenced. Thirteen variable sites were determined and 17…
The authors made 39 surveys (a total of 161 days) in the Tian-e-Zhou Oxbow of the Yangtze River, China, for observing 13 Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis) captured from…
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…
