  abstract = {{U}nder higher atmospheric {CO}2 concentrations, increases in soil moisture and, hence in terrestrial-aquatic carbon transfer are probable. {I}n a coupled terrestrial-aquatic experiment we examined the direct (e.g. through changes in the {CO}2 water concentration) and indirect (e.g. through changes in the quality and quantity of soil leachates) effects of elevated {CO}2 on a lake microbial community. {T}he incubation of soils under elevated {CO}2 resulted in an increase in the volume of leachates and in both chromophoric dissolved organic matter ({CDOM}) absorption and fluorescence in leachate. {W}hen this leachate was added to lake water during a 3-day aquatic incubation, we observed negative direct effects of elevated {CO}2 on photosynthetic microorganism abundance and a positive, indirect effect on heterotrophic microbial community cell abundances. {W}e also observed a strong, indirect impact on the functional structure of the community with higher metabolic capacities under elevated {CO}2 along with a significant direct effect on {CDOM} absorption. {A}ll of these changes point to a shift towards heterotrophic processes in the aquatic compartment under higher atmospheric {CO}2 concentrations.},
