Moss in the News

Living under a translucent rock can be quite comfortable — if you’re a moss in the Mojave Desert.

A graduate student at the University of California, Berkeley, found that some mosses in the California desert seek protection from the relentless sun and heat by sheltering under translucent quartz pebbles, essentially using the rocks as sunshades.

The soil under these rocks retains more moisture than exposed desert soil, said Jenna Ekwealor, while enough light leaks through the milky quartz to allow the tiny mosses to remain green with chlorophyll. Mosses actually prefer dim light, making these conditions ideal for growth. In contrast, nearby mosses in full sun are dried up and black. Read more.

Herd of fuzzy green “glacier mice” baffles scientists | NPR

In 2006, while hiking around the Root Glacier in Alaska to set up scientific instruments, researcher Tim Bartholomaus encountered something unexpected.

“What the heck is this!” Bartholomaus recalls thinking. He’s a glaciologist at the University of Idaho.

Scattered across the glacier were balls of moss. “They’re not attached to anything and they’re just resting there on ice,” he says. “They’re bright green in a world of white.” Read more.

Silver moss is a rugged survivor in the city landscape | The Conversation

Chances are you’ve walked over silver moss (Bryum argenteum) countless times without giving it a second glance. This moss, at home in moist environments as well as hot and cold deserts, is also a common denizen of cities worldwide and finds shelter in our pavement cracks. Read more.

Earth Notes: After a Fire, Pioneer Plants | KNAU Arizona Public Radio

The West’s pioneer spirit characterizes not only many of the region’s people, but also some of its plants. And a trio of pioneer species collectively called fire mosses, known on every continent, may prove an excellent tool for repairing burned-over lands on the Colorado Plateau. Read more.

Brain Food: Growing Biocrust | KNAU Arizona Public Radio

Scientists are concerned that soil in the Southwest is drying out and blowing away from climate change. Flagstaff-based ecologist Matt Bowker believes the key to protecting it lies in the biocrust, or top layer. He calls it “Earth’s living skin”, and he’s growing it in a lab at Northern Arizona University. Read more.

 

Kids love to play in the dirt. So Flagstaff ecologist Anita Antoninka is channeling that love into learning… using it as a way to teach kids about the effects of climate change on the earth’s biocrust. Today, she’s working with a seventh grade science class at Northland Preparatory Academy to see how a warming planet affects moss. Read more.
