Fungal decomposition of river organic matter accelerated by decreasing glacier cover

Nature Climate Change, Published online: 15 March 2021; doi:10.1038/s41558-021-01004-x

The impact of glacier retreat on fungal-driven decomposition in rivers is investigated using a standardized test across six countries. Less glacier cover is linked to increased decomposition, which is in turn associated with a greater abundance of fungi and a fungal cellulose-degrading gene, cbhI.
