BN013:
Investigating marine microbial interactions with stable isotopes


Session ID#: 27551

Session Description:
Stable isotopes provide a powerful tool for characterizing microbial interactions and their influence on biogeochemical cycles. Recent advancements have enabled the investigation of biologically relevant isotopes in higher resolution and at lower abundance than previously permitted. Examples of such techniques include, but are not limited to, stable isotope probing coupled to FISH-NanoSIMS, microarray (i.e. Chip-SIP), and biomolecule analyses. These types of approaches can be particularly valuable for determining the functional roles of microorganisms in complex communities. Furthermore, coupling compound-specific measurements with genomic techniques provides an unparalleled platform for detailed investigations of how microbial communities cycle nutrients. This session seeks to be a forum to discuss advances in techniques and applications in aquatic ecosystems. We invite investigations using different combinations of stable isotope approaches across a range of marine ecosystems (e.g., planktonic ecosystems, deep sea benthic ecosystems, coral reef ecosystems). We welcome approaches targeting entire microbial communities or specific populations. Our aim is to enhance the understanding of marine microbial interactions, as well as to identify challenges and develop avenues for future research using stable isotopes.
