Diversity and distribution of Tardigrada in Arctic cryoconite holes
Despite the fact that glaciers and ice sheets have been monitored for more than a century, knowledge on the glacial biota remains poor. Cryoconite holes are water-filled reservoirs on a glacier’s surface and one of the most extreme ecosystems for micro-invertebrates. Tardigrada, also known as water...

Despite the fact that glaciers and ice sheets have been monitored for more than a century, knowledge on the glacial biota remains poor.
