Age at sexual maturity and timing of the mating season were determined in male Atlantic walruses (Odobenus rosmarus rosmarus, L.) from the “North Water” subpopulation in northern Baffin Bay. Testes and epididymides of 174 male walruses (between 0

The reproductive tracts of 152 female Atlantic walruses Odobenus rosmarus rosmarus were analysed. The material was collected between 19 January and 19 November in 1977–78 ( n = 44) and 1988–91 ( n = 108) from the subsistence hunt by Inuit in nort

Serum samples from 419 polar bears (Ursus maritimus) from Svalbard and the Barents Sea (collected 1990-2000) and 108 polar bears from East Greenland (collected 1999-2004) were assayed for antibodies against Toxoplasma gondii using the modified agglut

A well-defined subsample of 128 subadult (3-5 years) polar bears (Ursus maritimus) from 19 sampling years within the period 1984-2006 was investigated for perfluoroalkyl contaminants (PFCs). Linear regression analysis of logarithmic-transformed media

Mercury concentrations in hair from 397 Greenland polar bears (Ursusmaritimus) sampled between 1892 and 2001 were analyzed for temporal trends. In East Greenland the concentrations showed a significant (p0.0001, n = 27) increase of 3.1%/year in the p
