GNPS - Temperature Effects on Metabolite-Mediated Autotroph-Heterotroph Carbon Transfer

Much of the bacterial secondary production in the aquatic ecosystems is supported by rapid uptake of labile metabolites released from phytoplankton, either directly through excretion and diffusion or indirectly through lysis and predation. This project seeks to investigate the effects of temperature stress on the metabolite pools produced and released by three model phytoplankton species (a diatom, a coccolithophore, and a cyanobacterium) that will assess changes in the composition and fate of metabolites transferredto bacteria. While focused on estuarine microbes, findings of this project will be broadly relevant to temperature effects on microbial autotrophic-heterotrophic metabolite transfer in freshwater, marine, and soil ecosystems.
