High-resolution X-ray computed tomographic scans were used to examine pterygoid sinus morphology within extant porpoise species and one delphinid (Tursiops truncatus), in order to consider: 1) intraspecific and interspecific variation…
Monitoring abundance and population trends of small odontocetes is notoriously difficult and labor intensive. There is a need to develop alternative methods to the traditional visual line transect surveys, especially…
High stranding frequency of porpoises, Phocoena phocoena, along the Dutch coast since 2006 has led to increased interest in the ecology of porpoises in the North Sea. Stranded porpoises were…
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…
Between mid-July and early August, an unusual mass mortality of cetaceans was detected on the Turkish Western Black Sea coast. 114 cetaceans (53 harbour porpoises, 9 common dolphins, 7 bottlenose…
During ship surveys harbor porpoises are only visible when breaking the sea surface to breathe, while during aerial surveys they may be seen down to 2 m below the surface.…
Offshore wind farms (OWF) will soon contribute to significant growth in the renewable energy sector. At present just a few OWF have been built. As of 2012, Germany has an…
Pile driving of large steel monopiles in offshore waters has increased rapidly in recent years due to the expanding development of offshore wind energy. In particular, Phocoena phocoena (harbor porpoise)…
Visually dominant animals use gaze adjustments to organize perceptual inputs for cognitive processing. Thereby they manage the massive sensory load from complex and noisy scenes. Echolocation, as an active sensory…
The seasonal surveys of stranded cetaceans were performed on the Turkish coast of the western Black Sea during summer 2007-spring 2009. Fifty stranded cetaceans were found, which included 24 harbour…
