near the tips of the phylogenetic tree (NTI $>$ 0) at taxonomic levels broader  than the OTUs established in this study (Figure~\ref{fig:tiledtree}).  Therefore, $^{13}$C-responders distribute into fewer clades than OTUs  (Figure~\ref{fig:tiledtree}). $^{13}$C-xylose responders formed clades at X.XX sequence divergence (consenTrait) (consenTRAIT metric, \citep{Martiny2013})  while our OTUs were established at 0.03 sequence divergence. % Fakesubsubsection:It's not clear whether the observed activity  Trophic interactions or the functional groups tuned to different resource
