Ice Spiders

Arctic spiders may hold clues to global warming

The littlest things may save us:

...Reclusive spiders living in the Arctic may yield clues to the impact of global warming...disruptions to tiny Arctic spiders, little studied and living much of their lives under snow, could ripple through the food chain...said Michael Nickel of Stuttgart University...Spiders adapted to living in the Arctic, with chill temperatures and little food, can take up to seven years to reach maturity, according to some studies. That compares to one to two years for similar species further south...
