简介
Glaciers are receding worldwide because of climate change, and as a consequence, glacier-fed streams are expected to undergo deep physical and chemical changes in the future, potentially inducing dramatic ecological shifts. At the base of glacier-fed stream ecosystems are bacteria, which, along with eukaryotic algae, form biofilms that drive biogeochemical transformations and fluxes of global relevance. Despite this importance, relatively little is known about the glacier-fed stream microbiome and even less on how it may be affected by climate change. The Vanishing Glaciers Project offers a novel and powerful opportunity to investigate this idea, with 16S rRNA amplicon data, shotgun metagenome sequencing, and physicochemical parameters assessed for glacier-fed streams distributed globally. Here, using data from 161 of the sampled streams, combined with glaciological modelling, we examined a) how the …
