Fig. 3: Structuring of community composition and the oscillations of ASVs and genes across years.
From: Seasonal recurrence and modular assembly of an Arctic pelagic marine microbiome
Non-metric multi-dimensional scaling of Bray-Curtis dissimilarities calculated after rarefying and Hellinger transforming ASV count data for a prokaryotic and b microeukaryotic communities over 4 years, wherein colours indicate months. c The count (left) and relative abundance (right) of prokaryotic ASVs, microeukaryotic ASVs and gene clusters for each oscillation signal. The relative abundances of ASVs and genes were subject to Fourier transformation, and oscillation signals were determined based on the amplitude of peak/trough dynamics within each annual cycle. An oscillation of 1 indicates a single peak/trough per year, reflecting a unimodal annual fluctuation in abundance. Boxplots illustrate the median, 25 and 75% percentile of the number and relative abundance of ASVs and gene clusters exhibiting each oscillation signal. The number of ASVs and gene clusters observed for each oscillation signal are included next to each boxplot.
