Glacier environment amplicon sequence

Using 16S rRNA gene amplicon sequencing, we investigated bacterial communities along the glacier-fed stream of the Tanggula Longxiazailongba Glacier, sampling from supraglacial, glacier terminal, and proglacial stream locations. Bacterial diversity pattern was driven by environmental variables. Different groups of glacier-originating bacteria exhibited distinct responses to environmental controls, leading to shifts in community structure along the stream gradient. These findings provide crucial insights into how climate change-induced glacier retreat may affect microbial diversity and community composition in downstream ecosystems.
