Marine Mammal Sci (2000)
(...) Our understanding of cetacean diving behavior has recently increased (Westgate et al. 1995, Heide-Jorgensen and Dietz 1995, Davis et al. 1996). However, there are few reports which measured swim…
Radio tracking finless porpoises (Neophocaena phocaenoides): Preliminary evaluation of a potential technique, with cautions
Würsig, B.; Wang, D.; Zhang, X.
Biology and Conservation of Freshwater Cetaceans in Asia (2000)
Three finless porpoises (Neophocaena phocaenoides) from the Yangtze River were fitted with cotton cloth vests and small radio transmitters. They were tracked for 2.6, 11.0, and 14.6 days in the…
Will harbour porpoises (Phocoena phocoena) habituate to pingers?
