Glacier-fed conditions decouple microbial genomic potential from realized carbon-substrate utilization

Description

Glacier meltwater changes hydrological connectivity and resource supply in proglacial lakes, but whether microbial genomic potential reflects realized carbon processing under these changing conditions remains unclear. Here, we combined two years of seasonal observations, genome-resolved metagenomics, and Biolog EcoPlate assays to compare microbial carbon-processing potential and realized substrate utilization during glacier-fed (GFD) and non-glacier-fed (NGFD) periods in a Tibetan proglacial lake.
