\citep{Cotner_2002} and to some extent demonstrated empirically  \citep{Stets_2008}, the effect that these shifts in biomass of each group have  on membership and structure of the photoautotroph and heterotrophic bacterial  community has not been directly evaluated in plankton or biofilms. In addition, how dynamics changes  in planktonic communities are propagated propagate  to biofilms during community assembly is not well understood. We designed this study to test a) if C subsidies shifted the biomass balance between autotrophs and heterotrophs within the biofilm or its seed pool, pool (i.e.  the plankton plankton)  and b) to measure how these putative changes in pool size altered membership and structure of the plankton communities and affected biofilm community assembly. To do so, we amended marine mesocosms with varying levels of labile C input and evaluated differences in photoautotroph and heterotrophic bacterial biomass in plankton and biofilm samples along the C gradient. In each treatment we characterized plankton and biofilm community composition by DNA sequencing of 16S rRNA genes and plastid 23S rRNA genes.
