The morning light backlights the impressive polar bear at the edge of this rock. The sun creates soft backlighting around this massive body in this B&W art photograph. Overall a calm and serene atmosphere came through the morning light.
Did you know that scientists can extract DNA from just a polar bear’s footprint in the ground? Incredible! Two small samples of snow from a polar bear track revealed not only the DNA of the polar bear that made it but even from a seal, it had recently eaten.
Polar Bears Are Apex Predators
As an apex predator at the top of the food web, polar bears can signal that there are problems in the Arctic marine ecosystem. They are likely to be among the most vastly affected species as the Arctic warms and sea ice melts. Undoubtedly, climate change is not the only threat to these magnificent creatures. The oil and gas industries are also harming their habitats through oil exploration. If a bear comes into contact with oil spills, it can reduce the insulating effect of a bear’s fur. This means they use more energy to get warm and can poison them if it gets in their system.
Polar bears, Ursus maritimus, are on the IUCN list as a threatened species.
