Cetaceans of Morocco have been poorly studied to date, and only sporadic information comes from scientific cruises for this group. In an attempt to learn more on the occurrence, distribution…
Signals used in naval and long-range fish detection sonar often contain harmonics which may influence the behavior of harbor porpoises (Phocoena phocoena) more than the lower fundamental frequencies, so the…
Large amounts of legacy unexploded ordnance (UXO) are still present in the North Sea. UXO are frequently accidentally encountered by fishermen and dredging vessels. Out of concern for human safety…
In 2006, a marked increase in harbor porpoise Phocoena phocoena strandings were reported in the Pacific Northwest of the USA, resulting in the declaration of an unusual mortality event (UME)…
The vaquita (Phocoena sinus) is a small and very elusive porpoise that ranges in a limited geographical area in the Gulf of California, Mexico. Despite various efforts to conserve this…
The vaquita (Phocoena sinus) is the most critically endangered cetacean species in the world and is a small porpoise endemic to the northern Gulf of California, Mexico. As fishing efforts…
For the conservation of endangered animals to be effective, information on population distribution and abundance requires regular updating from census efforts. The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) has recently…
We used variation at microsatellite loci and in mitochondrial DNA (mtDNA) to detect and quantify (1) hybridization between the harbour porpoises Phocoena phocoena and the Dall’s porpoises Phoconoides dalli and…
The coastal Runnelstone Reef, off southwest Cornwall (UK), is characterised by complex topography and strong tidal flows and is a known high-density site for harbour porpoise (Phocoena phocoena); a European…
Poyang Lake is the largest freshwater lake in China and flows into the Yangtze River. It is a traditional habitat for the endangered Yangtze finless porpoise, which has not been…
