Because we had no initial data for the 2008 survey, we initialized the
lake in a homogeneous composition, as would be expected from an
idealized dimictic lake that perfectly mixed throughout its entire depth
in the spring. In this case, themodel predicted the emergence of chemical
gradients from the initially homogeneous composition (Supplementary
Fig. 6) and the predicted distribution of chemical species accorded with
the single-time-point survey (Supplementary Fig. 3).
To relate the output of the model with our biological data, we
reinterpreted the modelled rates as predictions of microbial distribution.
Implicit biomass models, like the one we developed,
predict the rates of processes catalysed by all microbes performing
that process and assume that the biomass of the microbial community
equilibrates quickly to the changing chemical environment22.
They also assume that ‘everything is everywhere’ and are not constrained
by ecological processes such as dispersion. We therefore
