Quantifying the ecophysiology of growing microbes responding to warming along a productivity gradient of the Marr Ice Piedmont Glacier, West Antarctic Peninsula


ABSTRACT: Our overarching goal is to understand how microbes along a glacier forefield chronosequence and productivity gradient interact with their environment, how this influences carbon and nitrogen cycling, and how the microbes respond to temperature increases. Specifically, using the novel approach of quantitative SIP paired with metagenomic sequencing, we will calculate growth rates for targeted functional genes and metagenome assembled genomes, quantifying their ecophysiology, in situ. And when paired with gene expression using metatranscriptomic libraries and metabolite production, we will gain a clearer understanding of how microbes grow, how they cycle carbon and nitrogen and how their metabolic activity changes in response to warming. The work (proposal:https://doi.org/10.46936/10.25585/60008115) conducted by the U.S. Department of Energy Joint Genome Institute (https://ror.org/04xm1d337), a DOE Office of Science User Facility, is supported by the Office of Science of the U.S. Department of Energy operated under Contract No. DE-AC02-05CH11231.
