Antarctic nematodes and climate change

The frozen desert valleys of Antarctica are among the world's most inhospitable environments. The landscape is so barren that just 30 years ago, experts did not think it could support life.

But beneath the surface, microscopic worms called nematodes thrive in a unique ecosystem - and they are helping researchers understand the effects of climate change.

Soil scientist Diana Wall has spent two decades studying Antarctic nematodes, ground-breaking work that this year earned her one of science's top awards - the Tyler Prize for Environmental Achievement.
But Rambo is on the ropes. As temperatures rise and more ice melts, another nematode that thrives in wet soil, Eudorylaimus glacialis, is moving in. And as the two species slug it out for Antarctic dominance, Rambo appears to be losing, declining 65% in the last few years.
