Developing a New Trait-based Understanding of Microbial Communities Based on Metabolic and Elemental and Macromolecular Constraints

Zoe Finkel
Dalhousie University, Canada

We are conducting a suite of laboratory experiments to quantify the relationship between growth rate and the macromolecular and elemental composition of key phytoplankton taxa across a range of cell sizes and taxonomic groups to facilitate the development, parameterization and testing of a new trait-based marine microbial growth model.
