Mammal Study (2003)
We carried out an aerial survey to estimate the abundance of finless porpoises Neophocaena phocaenoides off the Pacific coast of eastern Japan between Sendai Bay (38°23’N) and the mouth of…

There is a high risk that incidental mortality (bycatch) in gillnets will lead to extinction of the vaquita Phocoena sinus, a small porpoise endemic to Mexico’s northern Gulf of California.…
Persistent organochlorines (PCBs and p,p′-DDE) in the bodies of dalli- and truei-type Dall's porpoises (Phocoenoides dalli) from the Bering Sea and the northwestern North Pacific were used as chemical tracers…
Small cetaceans are by-caught in salmon gillnet fisheries in British Columbia (BC) waters. In Canada, there is currently no generic calculation to identify when management action is necessary to reduce…
Abundance of harbor porpoise (Phocoena phocoena) was estimated from data collected during vessel surveys conducted throughout the inland waters of Southeast Alaska. Line-transect methods were used during 18 seasonal surveys…
The vaquita Phocoena sinus is a small porpoise that is endemic to the northern Gulf of California, Mexico. It is the most critically endangered marine small cetacean in the world.…
Muc Mhara – Ireland’s smallest whale. Proceedings of the 2nd Irish Whale and Dolphin Group International Whale Conference. Papers presented include, “Introduction: The harbour porpoise or Muc Mhara”, “An Irish…
Harbour Porpoise (Phocoena phocoena) are a small marine mammal reaching a length of about 2.2 m and weight of about 75 kg when fully grown, making them the smallest cetacean…
Reproductive failure in mammals due to exposure to polychlorinated biphenyls (PCBs) can occur either through endocrine disrupting effects or via immunosuppression and increased disease risk. To investigate further, full necropsies…
Cetaceans rely critically on sound for navigation, foraging and communication and are therefore potentially affected by increasing noise levels from human activities at sea. Shipping is the main contributor of…
