Supplemental Material

Temporal patterns in glycolate-utilizing bacterial community composition correlate with phytoplankton population dynamics in humic lakes



Sara F. Paver and Angela D. Kent



Figure S1a. Network of phytoplankton and glcD OTU population-level interactions in Crystal (CB) and South Sparkling (SSB) Bogs as determined by local similarity analysis [1] and Pearson correlations. Phytoplankton are represented by rectangles and glycolate-utilizing bacterial populations are represented by circles. Green lines indicate positive interactions and red lines indicate negative interactions. Dotted lines signify a time delay in an interaction, with an arrorow pointing to the OTU that is behind the other in time. Only significant interactions (p<0.001) are shown. Phytoplankton abbreviations: Aster, Asterionella; Cry, Cryptomonas; Dino, Dinobryon; Gf, Gymnodinium fuscum; Mall, Mallomonas; Oo, Oocystis, Pc, Peridinium cinctum; Pl, Peridinium limbatum; Pu, Peridinium umbonatum; Puu, Peridinium umbonatum umbonatum; Syn, Synura. Bacterial OTU codes indicate the primer (Forward or Reverse), enzyme (AluI or RsaI), and terminal restriction fragment length.


Figure S1b. Network of phytoplankton and glcD OTU population-level interactions in Trout (TB) and North Sparkling (NSB) and Why Not (WB) Bogs as determined by local similarity analysis [1] and Pearson correlations. Due to the number of significant interactions in WB, a group attribute layout was selected to depict correlations instead of a hierarchic layout. Phytoplankton are represented by rectangles and glycolate-utilizing bacterial populations are represented by circles. Green lines indicate positive interactions and red lines indicate negative interactions. Dotted lines signify a time delay in an interaction, with an arrow pointing to the OTU that is behind the other in time. Only significant interactions (p<0.001) are shown. Phytoplankton abbreviations: Aster, Asterionella; Cry, Cryptomonas; Dino, Dinobryon; Gf, Gymnodinium fuscum; Mall, Mallomonas; Oo, Oocystis, Pc, Peridinium cinctum; Pl, Peridinium limbatum; Pu, Peridinium umbonatum; Puu, Peridinium umbonatum umbonatum; Syn, Synura. Bacterial OTU codes indicate the primer (Forward or Reverse), enzyme (AluI or RsaI), and terminal restriction fragment length.
