Prevalence of antibodies against Toxoplasma gondii in polar bears (Ursus maritimus) from Svalbard and East Greenland.
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 agglutination test. Antibody prevalences were 3.6% among cubs dependent on their mothers and 21.4% among subadults and adults. Among subadults and adults...
متن کاملSerum iron and selected biochemical values in free-ranging black rhinoceros (Diceros bicornis) from South Africa.
Serum samples collected from 20 black rhinoceros (Diceros bicornis) were analyzed for iron values from six different areas in South Africa. In addition, biochemical profiles were performed on individual samples. Comparisons of iron values from free-ranging black rhinoceros and from 28 free-ranging white rhinoceros (Ceratotherium simum) were conducted by location and age. Among the free-ranging ...
متن کاملPolar bears shift from thinning ice
A long-term study by the US Geological Survey (USGS) suggests that recent changes in the quality and availability of sea ice in northern Alaska are the most likely explanation for a decrease in female polar bears bringing up cubs on sea ice and an increase in basing themselves on land. Researchers from the USGS used satellite telemetry to evaluate changes in the distribution of female nesting s...
متن کاملA Case of Offspring Adoption in Free-Ranging Polar Bears (Ursus maritimus)
During a study of the reproductive ecology of polar bears (Ursus maritimus) in western Hudson Bay (Canada), we documented a case of litter adoption. In an eight-month period, a ten-year-old adult female lost a litter of two cubs-ofthe-year and adopted three other cubs-of-the-year. This is the first reported case of natural offspring adoption in polar bears, and its significance as a reproductiv...
متن کاملHaematological and biochemical reference intervals for free-ranging brown bears (Ursus arctos) in Sweden
BACKGROUND Establishment of haematological and biochemical reference intervals is important to assess health of animals on individual and population level. Reference intervals for 13 haematological and 34 biochemical variables were established based on 88 apparently healthy free-ranging brown bears (39 males and 49 females) in Sweden. The animals were chemically immobilised by darting from a he...
