Atacama plants record fog history

Chilean scientists have traced a 3,500-year record of fog behaviour in the Atacama Desert by examining a group of plants that live solely off the dampness in the air.

Tillandsia are a perfectly adapted opportunist. These wiry, grey plants have no roots. They clutch weakly at sand dunes, and arrange themselves at every spatial scale to maximise their capture of the fog.

Claudio Latorre Hidalgo from the Catholic University of Chile spoke to our correspondent Jonathan Amos.
