Some odontocetes and bats vary both click intensity and receiver sensitivity during echolocation, depending on target range. It is not known how this so-called automatic gain control is regulated by…

During echolocation, toothed whales produce ultrasonic clicks at extremely rapid rates and listen for the returning echoes. The auditory brainstem response (ABR) duration was evaluated in terms of latency between…
Total Hg levels were determined in 17 harbour porpoises Phocoena phocoena collected in the North Sea and the Kattegat (muscle, liver and kidney), as well as in a sperm whale…
(...) A review of the status of harbor porpoise, Phocoena phocoena, in the U.S. waters of the western North Atlantic identified substantial information gaps in our knowledge about this species,…
(...) Harbor porpoise, Phocoena phocoena, have been caught incidentally in set gill nets off the central California coast since at least 1958 (Norris and Prescott, 1961). The annual mortality of…
1. The status of small cetaceans in the North Sea and adjacent waters has been of concern for many years. Shipboard and aerial line transect surveys were conducted to provide…
Twenty-eight odontocete species were identified as occupying sub-Antarctic and Antarctic habitat covered by the 1994 IWC-established Southern Ocean Sanctuary. Toothed whales evidently play an important part in the Antarctic polar…
Hearing is extremely important for cetaceans because it is their “principal sense” (Weilgart, 2007) thus the harbor porpoise and other marine animals are highly dependent on sound for survival. This…
Seventy-eight harbour porpoises, Phocoena phocoena, (33 females, 45 males) were obtained from the summer (June-September) cod fishery incidental-by-catch in the Gulf of St. Lawrence, and examined for the presence of…
The Expert Panel on Vaquita Acoustic Monitoring had its second meeting on April 28, 2015 to analyze the first four seasons (2011-2014) of the acoustic monitoring program. Results indicate an…
