Quantifying and Linking Omics, Physiology & Models in Marine Microbiology
Session ID#: 259765
Session Description:
Microbial communities govern ocean ecology and biogeochemistry, yet a major gap persists between knowing
who is present and understanding
how fast they transform energy and matter. This session seeks to address this by uniting two complementary approaches:
- Linking omics and physiology. We invite studies that connect -omics data with measurements of microbial traits and rates, such as nutrient uptake, photosynthesis, respiration, etc. to reveal functional drivers of ecosystem processes.
- Making it quantitative. We also welcome work that provides numerical estimates on reaction kinetics, cellular resource-allocation budgets (C, N, P, Fe, energy), whole-community fluxes, and the uncertainties around them. Experimental, field, and in silico approaches that translate molecular information into parameterizable rates for ecological models are encouraged.
We are keen on contributions that quantify marine microbial processes and their impacts on the environment, compare “omics-inferred” activity with rate measurements, and benchmark emerging proxies and workflows. We are also interested in studies that integrate laboratory manipulations, time-series observations, and/or mechanistic or statistical models. This session aims to catalyze inter-methodological dialogue between experimentalists and modelers, paving the path from cellular machinery to ecosystem functioning, which is a major goal of the international working groups PRIMO (https://primoscorwg.org/) and BioGeoSCAPES (https://biogeoscapes.org).
