In small birds, mass-dependent predation risk (MDPR) is known to make the trade-off between avoiding starvation and avoiding predation dependent on individual mass. This occurs because carrying increased fat reserves…


Investigating potential associations between chronic exposure to polychlorinated biphenyls and infectious disease mortality in harbour porpoises from England and Wales

Jepson, Paul D.; Bennett, Peter M.; Allchin, Colin R.; Law, Robin J.; Kuiken, Thijs; Baker, John R.; Rogan, Emer; Kirkwood, James K.
Science of the Total Environment (1999)

Bioaccumulation of immunosuppressive organochlorines like polychlorinated biphenyls (PCBs) may pose a threat to the health and viability of cetacean populations. To investigate possible associations between chronic exposure to PCBs and…

Herder, V.; van de Velde, N.; Højer Kristensen, J.; van Elk, C.; Peters, M.; Kilwinski, J.; Schares, G.; Siebert, U.; Wohlsein, P.
Journal of Comparative Pathology (2015)

A 7-year-old female harbour porpoise (Phocoena phocoena), born and held in captivity, suffered from reduced consciousness, imprecise and circling swimming movements and long phases of immobility over a period of…


PCBs, cause of death and body condition in harbour porpoises (Phocoena phocoena) from British waters

Kuiken, Thijs; Bennett, Peter M.; Allchin, Colin R.; Kirkwood, James K.; Baker, John R.; Lockyer, Christina H.; Walton, Michael J.; Sheldrick, Martin C.
Aquatic Toxicology (1994)

Polychlorinated biphenyls (PCBs) suppress immunity, and may have exacerbated the effects of recent morbillivirus epizootics in harbour seals (Phoca vitulina) and striped dolphins (Stenella coeruleoalba). To test the hypothesis that…


Observations on the baiji (Lipotes vexillifer) and the finless porpoise (Neophocaena asiaeorientalis) in the Changjiang (Yangtze) River between Nanjing and Taiyangzhou, with remarks on some physiological adaptations of the baiji to its environment

Zhou, K.; Pilleri, G.; Li, Y.
Investigations on Cetacea (1979)

Two species of dolphin inhabit the Changjiang (Yangtze): Lipotes vexillifer MILLER, 1918 (known as Baiji in Chinese) and the Finless porpoise, Neophocaena asiaeorientalis PILLERI and GIHR, 1972. Although quite a…


An investigation into the causes of an unusual porpoise (Phocoena phocoena and Phocoenoides dalli) mortality event in southern British Columbia

Baird, R. W.; Guenther, T. J.; Lewis, R. J.; McAdie, M. L.; Cornish, T. E.
Report No. IIHS3-050 (1994)

Cetacean strandings have typically been classified into two types: 1) single strandings (including a mother/offspring pair); and 2) mass strandings. Singly stranded cetaceans have been reported world-wide wherever populations of…
