Pronounced dive responses through peripheral vasoconstriction and bradycardia enable prolonged apnoea in marine mammals. For most vertebrates, the dive response is initiated upon face immersion, but little is known about…
Echolocating mammals generally target individual prey items by transitioning through the biosonar phases of search (slow-rate, high-amplitude outputs), approach (gradually increasing rate and decreasing output amplitude) and buzzing (high-rate, low-amplitude…
The dive response, a decrease in heart rate (fH) and peripheral vasoconstriction, is the key mechanism allowing breath-hold divers to perform long-duration dives. This pronounced cardiovascular response to diving has…
Among the spirit specimens of mammals in the United States National Museum are several of the Chinese black finless porpoise, Neomeris phocaenoides (Cuvier), which were presented to the Museum by…
Porpoise. The Porpoise [Phocaena communis, or P. phocaena) is the smallest and most common of the Cetaceans found in the seas around the British Isles, and it also frequents the…
The morphology of diatoms which consistently occur in circular to oval colonies on the skin of North Pacific Dall's porpoise was examined. Two previously described cetacean diatoms Stauroneis aleutica Nemoto…
There has been increasing concern about trace element accumulation in finless porpoises over the past decades, while the long-term variation of its concentration has been little known. Since most soft…
The first assessment of cetacean density and abundance by linear transect survey was conducted in 2016 and 2017 in the shallowest coastal area of the Ukrainian sector of the north-western…
Harbour porpoise (Phocoena phocoena) is listed under the Annex II of the European Habitats Directive (Directive 92/43/CEE) and Member States are required to designate special areas of conservation to protect…
Stomach contents of harbour porpoises (Phocoena phocoena) collected in the Netherlands between 2003 and 2013 were inspected for the presence of plastic and other man-made litter. In 654 stomach samples…
