From tropics to poles: study reveals diversity of life in soils

Microscopic animals that live in soils are as diverse in the tropical forests of Costa Rica as they are in the arid grasslands of Kenya, or the tundra and boreal forests of Alaska and Sweden.That conclusion is found in research results published today in the journal Proceedings of the National Academy of Sciences.Scientists have generally accepted that a wider range of species can be found above ground at the equator than at the Earth's poles. But this study proves for the first time that the same rules don't apply to the nematodes, mites and springtails living underground.
