Federal polar bear research critically flawed, says new study
Research done by the U.S. Department of the Interior to determine if global warming threatens the polar bear population is so flawed that it cannot be used to justify listing the polar bear as an endangered species, according to a study being published later this year in Interfaces, a journal of the Institute for Operations Research and the Management Sciences (INFORMSŪ).
Arctic marine mammals on thin ice
The loss of sea ice due to climate change could spell disaster for polar bears and other Arctic marine mammals. The April Special Issue of Ecological Applications examines such potential effects, puts them in historical context, and describes possible conservation measures to mitigate them. The assessment reflects the latest thinking of experts representing multiple scientific disciplines.
Hunting males could harm polar bear populations
New research by the University of Alberta in Edmonton suggests that current wildlife management practices in Canada could make it harder for polar bears to find mates.
Next 50 years may be last for polar bears
Shrinking sea ice will eliminate nearly all of the world's polar bear population in the next 50 years, U.S. government scientists predict.
Russia to make polar bear hunting legal

Why are lions not as big as elephants?
Carnivores are some of the widest ranging terrestrial mammals for their size, and this affects their energy intake and needs. This difference is also played out in the different hunting strategies of small and large carnivores. Smaller species less than 15-20 kg in weight specialize on very small vertebrates and invertebrates, which weigh a small fraction of their own weight, whereas larger species (>15-20 kg) specialize on large vertebrate prey near their own mass.
Warming Climate May Put Chill on Arctic Polar Bear Population
Some travel agencies touting Arctic tours have been revving up their recent promotions to tourists about the increased likelihood they will spot polar bears in this region where several populations of polar bears live. According to scientists from NASA and the Canadian Wildlife Service, these increased Arctic polar bear sightings are probably related to retreating sea ice triggered by climate warming and not due to population increases as some may believe.
