Assuming the cause to be something like the wind that pushes tumbleweeds, they got down and dirty with the fuzzy dirt balls – attaching a thin loop of wire strung with identifying beads around 30 of them. Glacier mice are colonies of mosses found on some glaciers.They are composed of multiple species of moss and can also host other species, such as nematode worms, springtails, and water bears. Perhaps the movement and moss growth is required to feed their gut microbes. They tracked 30 glacier mice by tagging each moss ball with a loop of wire and some beads. The researchers found that the glacier mice were pretty indestructible. Glacier mice are often spotted resting on a thin column of ice. Glacier mice aren’t new and have been spotted in Alaska, Iceland, Svalbard and South America. If the glacier mice stopped rotating, the moss that comes into permanent contact with the glacier surface would die. The glacier mice didn’t follow any pattern that the researchers checked. That’s because the ice nearby has been melted, while the ice beneath the moss ball has been protected from the sun. The Matanuska glacier sits between the Chugach and the Talkeetna mountain ranges, and because glaciers are ever-moving forms, it is constantly grinding away at […] They measured the movements for 54 days, then left and returned in 2010, 2011 and 2012 and measured them again.

(Source: Carsten ten Brink, via Flickr.com.) Mice on the move. “We show that glacier moss balls move an average of 2.5 cm per day in herd-like fashion, initially to the south and later towards the southwest, and their movements are positively correlated with glacier ablation. Use up and down arrows to change selection. Scientists Study Baffling Movements of Glacier Mice : Short Wave In 2006, while hiking around the Root Glacier in Alaska, glaciologist Tim Bartholomaus encountered … But glacier mice are actually balls of moss, each about the size of a tennis ball, and typically shaped into slightly squashed spheres that amass around pebbles on … They even changed directions and speeds over time. This fits in with prevailing theories that the microbial ecosystem on the glaciers depends on moss – something that could suffer with climate change. They monitored the movement of the moss balls for 54 days in … The first thing he discovered is that the glacier mice are covered with different types of moss. Although what preconditions are necessary for glacier mice to form has yet to be determined, they have been observed in Alaska, Chile, Iceland, Svalbard, and Venezuela. But glacier mice are actually balls of moss, each about the size of a tennis ball, and typically shaped into slightly squashed spheres that amass around pebbles on the surfaces of some glaciers. Glacier mice can grow to the size of a tennis ball. Bartholomaus told NPR the movement was similar to a school of fish or a flock of birds and defied conventional explanation.

A recent study from the journal Czech Polar Reports presents interesting findings about a rarity on glaciers: moss.. Glacier Mosses(Credit: Flickr) When glaciers have a certain amount of moisture and cryoconite—a base layer that consists of small rock particles, soot, and microbes that have accumulated on glaciers— sometimes mosses can grow on them. Stephen Coulson, Author provided. It is this rotation that enables the glacier mice to grow moss around the whole of their outer surfaces – sometimes creating near perfect spheres. That was the initial scientific assessment of University of Idaho glaciologist Tim Bartholomaus, co-author of the new study published recently in Polar Biology. Scattered across the glacier were balls of moss. Surprisingly, the dominant moss ball movement direction does not align with the prevailing wind or downslope directions, nor with the dominant direction of solar radiation. The mice travel about one inch (2.5 centimeters) a day. One day while hiking on Root Glacier, they came across a herd of soft, pillowy clumps of moss—these glacier moss balls, made of moss usually wrapped … Yes, cutting open a glacier moss exposed water bears (tardigrades) and tiny worms. The moss continues to grow and insulates the glacier surface, resulting in the moss becoming elevated on a pedestal as the surrounding ice melts.
