Short summary
Cryoconite holes are ponds on the glacier surface that play an important role in glacier nutrient pathways. This paper presents the first description of the carbon and nitrogen isotopic composition of cryoconite consumers (tardigrades and rotifers) and their potential food. We showed that consumers differ in nitrogen isotopes and carbon isotopes vary between taxa and between glaciers. The study contributes to improving knowledge about cryoconite hole functioning and cryoconite trophic networks.
