Fig. 5: Composition of abundance and carbon use.
From: Nutrients cause consolidation of soil carbon flux to small proportion of bacterial community
Ordinations generated by principal coordinates analysis (PCoA) of Bray–Curtis dissimilarities. Points represent centroids across replicates for each ecosystem (symbol MC mixed conifer forest, PP ponderosa pine forest, PJ piñon pine-juniper scrubland, GL desert grassland) and treatment (color control no amendment, C = carbon—glucose—only, C + N = carbon and nitrogen—[NH4]2SO4) (n = 3 experimental replicates). Ellipses represent multivariate standard error ranges for ecosystem group position (95% confidence). Percentages along axes represent the percent of multivariate dispersion explained by each PCoA dimension. a Beta diversity of relativized abundances. b Beta diversity of relativized carbon use values (respiration plus biomass production, μg carbon per g soil per week).
