(Phys.org) —A team of researchers from the University of Alberta led by, Catherine La Farge, has found that mosses and liverworts covered by ice over 400 years ago and now exposed due to glacial melting, are able to start growing again. In their paper published in the journal Proceedings of the National Academy of Sciences, the team describes how carbon dating showed the plants to be from a time just prior to the Little Ice Age.
