Long term chronic nitrogen effects on microbial community manuscript now published!

Our manuscript detailing the changes in microbial diversity and community composition in response to chronic nitrogen input using a long-term experiment has now been published in Applied Soil Ecology! We discovered that soil inorganic nitrogen and pH were prominent predictors of microbial abundance - all work led by Tim Grant from CSUSM. Read more here.

Mean (±SE; n = 4 plots/treatment) sequence counts for Proteobacteria (Pro), Actinobacteria (Act), Bacteroidetes (Bac), Firmicutes (Fir), Acidobacteria (Aci), Verrucomicrobia (Ver), Planctomycetes (Pla), and Chloroflexi (Chl) bacterial phyla in coastal sage scrub (CSS) exposed to ambient (control) and elevated N (N) during the spring (green) and fall (brown). Also shown are results of a two-way ANOVA or permutation test with 1 factor and 12 error degrees of freedom (p-value only) for effects of treatment (N), season (S), and their interaction (N × S). NS = not significant (p > 0.05).
