They come from a group from the University of Alberta, who were exploring an area around the Teardrop Glacier, high in the Canadian Arctic.
The glaciers in the region have been receding at rates that have sharply accelerated since 2004, at about 3-4m per year.
That is exposing land that has not seen light of day since the so-called Little Ice Age, a widespread climatic cooling that ran roughly from AD 1550 to AD 1850.
"We ended up walking along the edge of the glacier margin and we saw these huge populations coming out from underneath the glacier that seemed to have a greenish tint," said Catherine La Farge, lead author of the study.
Bryophytes are different from the land plants that we know best, in that they do not have vascular tissue that helps pump fluids around different parts of the organism.

So, what with all the global warming of the 20th century and all, the world’s temperature is now back to where it was in around 1550?

Not local, so I wouldn't have a clue. I'm not big on ornamentals anyway.
Bluebonnets, for all that they are pretty.... and Lady Bird Johnson loved 'em...
I could do without 'em.
I can't eat 'em.

They’ve identified a plant species that’s adapted to cyclic variations in climate warming and cooling.
