Ötzi the Iceman is a remarkable 5,300-year-old human specimen found frozen in ice approximately 3,200 meters above sea level in the Italian Alps. He was frozen alongside his clothing and gear as well as an abundant assemblage of plants and fungi. In this study, Dickson and colleagues aimed to identify the mosses and liverworts preserved alongside the Iceman. Today, 23 bryophyte species live the area near where Ötzi was found, but inside the ice the researchers identified thousands of preserved bryophyte fragments representing at least 75 species. It is the only site of such high altitude with bryophytes preserved over...

Plants that were frozen during the "Little Ice Age" centuries ago have been observed sprouting new growth, scientists say. Samples of 400-year-old plants known as bryophytes have flourished under laboratory conditions. Researchers say this back-from-the-dead trick has implications for how ecosystems recover from the planet's cyclic long periods of ice coverage. The findings appear in Proceedings of the National Academy of Sciences. They come from a group from the University of Alberta, who were exploring an area around the Teardrop Glacier, high in the Canadian Arctic.

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...
