What can we learn about our lakes by listening to the genomes we find in them?
Microbes drive nearly all of the biogeochemical processing in our freshwater lakes, but we know surprisingly little about the “freshwater microbiome”. We are using time-series metagenomes collected from several Wisconsin lakes to study how freshwater microbes provide essential ecosystem services such as carbon cycling and nutrient (re)cycling. We are interested in how these organisms interact with one another, and with phytoplankton, to carryout essential lake functions. We are also using targeted metatranscriptomics to confirm gene expression and generate more hypotheses about interactions. Our ultimate goal is to create multi-scale organism-centric predictive models to determine how communities will respond to environmental change, and how these communities will then influence in-lake processes.
All qBio sponsored talks take place on Wednesdays at 2:00 p.m. in the 3rd floor Orchard View room of the Discovery Building unless otherwise noted. Talks are open to the public. Access to the room is via the elevator behind Aldo’s Cafe in the Northeast corner of the building.
