Back to life after 1,500 years
Date:3/17/2014

Researchers from the British Antarctic Survey and Reading University have demonstrated that, after over 1,500 years frozen in Antarctic ice, moss can come back to life and continue to grow. For the first time, this vital part of the ecosystem in both polar regions has been shown to have the ability to survive century to millennial scale ice ages. This provides exciting new insight into the survival of life on Earth.

The team, reporting in Current Biology this week, observed moss regeneration after at least 1,530 years frozen in permafrost. This is the first study to show such long-term survival in any plant; similar timescales have only been seen before in bacteria. Mosses are known to survive environmental extremes in the short-term with previous evidence confirming up to a 20 year timescale for survival. Their potential to survive much longer timescales had not previously been examined.

Mosses are an important part of the biology of both polar regions. They are the dominant plants over large areas and are a major storer of fixed carbon, especially in the north.

Co-author Professor Peter Convey from the British Antarctic Survey explains:

"What mosses do in the ecosystem is far more important than we would generally realise when we look at a moss on a wall here for instance. Understanding what controls their growth and distribution, particularly in a fast-changing part of the world such as the Antarctic Peninsula region, is therefore of much wider significance."

The team took cores of moss from deep in a frozen moss bank in the Antarctic. This moss would already have been at least decades old when it was first frozen. They sliced the frozen moss cores very carefully, keeping them free from contamination, and placed them in an incubator at a normal growth temperature and light level. After only a few weeks, the moss began to grow. Using carbon dating, the team identified the moss to be at least 1,530 years of a
