Niche separation increases with genetic distance among bloom-forming cyanobacteria

Abstract: 25Bacterial communities are composed of distinct groups of potentially interacting lineages, each 26 thought to occupy a distinct ecological niche. It remains unclear, however, how quickly niche 27 preference evolves and whether more closely related lineages are more likely to share ecological 28 niches. We addressed these questions by following the dynamics of two bloom-forming 29 cyanobacteria genera over an 8-year time-course in Lake Champlain, Canada, using 16S 30 amplicon sequencing and measurements of se… Show more

“…the sum minus the number of shared ASVs (union). Alternatively, niche overlap between the taxa found in the single-resource media (20,21) might bring the expected number of species down to the maximum richness observed in the constituent singles; in the case of glucose + hydroxyproline, 24 ASVs. However, when we measured the richness of the communities grown in a media supplied with equal amounts of glucose and hydroxyproline, we found only ~16 ASVs on average, which is significantly lower than both expectations (Fig.…”

“…We obtained a median of 37 682 sequences per sample. Using a similar approach as described in the study by Tromas et al ., (), we processed the sequences with SmileTrain (https://github.com/almlab/SmileTrain/wiki; Preheim et al ., ) for read quality filtering, primer removal, chimera filtering, and merging using USEARCH (version 7.0.1090, http://www.drive5.com/usearch/, default parameter) (Edgar, ), Mothur (version 1.33.3) (Schloss et al ., ), and Biopython (version 2.7). Minimum entropy decomposition (MED) was then applied to the filtered and merged reads to partition sequence reads into MED nodes (Eren et al ., ).…”

“…As described in the study by Tromas et al . (), we used a latent variable model (LVM) framework (boral package in R; Hui, , Warton et al ., ) to explore how Synechococcus nodes co‐responded to abiotic gradients and used these co‐responses as indicators of niche similarity. That is, for each abiotic factor, we ran separate LVMs, regressing the bacterial community as a function (both linear and non‐linear) of the given factor.…”
