Hearing sensitivity, during trials in which a warning sound preceding a loud sound, was investigated in two harbor porpoises (Phocoena phocoena). Sensitivity was measured using pip-train test stimuli and auditory…
A total of 98 marine mammal records from Iranian coastal waters of the Persian Gulf and Gulf of Oman were compiled of which 66 are previously unpublished new records. Seventy-nine…
(...) Several studies on the population and distribution of marine mammals were conducted between 1978 and 1981 in the North Pacific Ocean under a United States-Japan cooperative agreement of the…
(...) In this paper we present results on diversity, local distribution and group composition of cetacean species along inshore waters of the fjord Puyuhuapi and Channels Jacaf and Moraleda (between…
Ships and wind turbines generate noise, which can have a negative impact on marine mammal populations by scaring animals away. Effective modelling of how this affects the populations has to…

Offshore wind farms constitute a new and fast growing industry all over the world. This study investigates the long term impact on harbour porpoises, Phocoena phocoena, for more than 10…
(...) During April 1997 the acoustic detector was successfully used to detect vaquitas for the first time. On that occasion we surveyed on a fixed location, aboard an outboard motor…
We examined the stomach contents of 87 finless porpoises (Neophocaena phocaenoides) in the Ariake Sound–Tachibana Bay area and Omura Bay in western Kyushu, Japan, between 1987 and 1992. Fish (Gobiidae…
