this pattern is expected to continue as climates everywhere changes and temperatures go up. As Earth warms up‚ the glaciers in the Arctic start to melt‚ and species such as the polar bear and the arctic fox that depend on the sea ice‚ will start to disappear and only be available for viewing in places such as zoos. The polar bear and the arctic fox are not just the only species that will be affected. The fish‚ birds‚ marine mammals‚ and even the algae that grows on the undersides of the glaciers will

One of the most southerly populations of polar bears in the world -- and the best studied -- is struggling to cope with climate-induced changes to sea ice‚ new research reveals. Based on over 10 years’ data the study‚ published in the British Ecological Society’s Journal of Animal Ecology‚ sheds new light on how sea ice conditions drive polar bears’ annual migration on and off the ice.

Evolution of Polar Bears The observed fossil transitions that inform our knowledge of Polar Bear speciation are very well documented. Bear fossils change through time: generally‚ when examining the fossil record‚ successively deeper levels of sediments or sedimentary rocks yield successively older fossils. For some transitions from one species to another‚ one can find a well-characterized series of transitional specimens leading the observer across the species "boundaries" (Kurten‚ 1976). Sometime
