Document Summary
Why would photoperiod evolve to be a trigger for anti-freeze protein production, if it"s an adaptation to. Photoperiod does not change but the length of time snow is in the area will (melts faster because its. How will climate change affect the fur of the arctic hare? warmer) so their fur is mismatched. Freeze intolerant: are there any freeze-tolerant endotherms, do all endotherms attempt to regulate a constant. The fact that the infrared photo of the polar bear doesn"t show up means its well-insulated. Stocky limbs, short ears, short tails (that minimizes heat loss) Hollow hair traps heat emitted from the skin. Algae grows in the hollow guard hair in the polar bear"s fur because of a warmer climate (like in a. Never overweight because they spend extra energy trying to get rid of the energy. Brown bears and polar bears ranges are starting to overlap. Where they get their food, land vs. sea.
