El hielo: reserva de vida durante el invierno

Abstract

Cuando llega el invierno austral y la temperatura del aire desciende, se forma hielo en la superficie del océano Antártico. Las aguas quedan así aisladas de la atmósfera. Si, además, nieva, la débil luz invernal no alcanza las aguas, que permanecenen la oscuridad. Lo mismo ocurre en un lago alpino. En esos momentos cobra importancia la vida microbiana del hielo. Por un lado, las bacterias que medran sobre el hielo utilizan el carbono orgánico que ha quedado allí atrapado. Numerosas algas unicelulares crecen en las cavidades; se mueven a través de los canales hasta encontrar un poco de luz que les permita llevar a cabo la fotosíntesis. Si la luz escasea, utilizarán el hielo a modo de refugio para hibernar: allí se mantendrán con una actividad mínima, pero sin ser arrastradas por las aguas, hasta que las condiciones ambientales mejoren y les permitan reproducirse.
