Back to the roots, desiccation and radiation resistances are ancestral characters in bdelloid rotifers
Abstract Background Bdelloid rotifers are micro-invertebrates distributed worldwide, from temperate latitudes to the most extreme areas of the planet like Antarctica or the Atacama Desert. They have colonized any habitat where liquid water is temporarily available, including terrestrial environments...
