Reconstruction of a soil microbial network induced by stress temperature

By applying a nonlinear time-series analysis to the metagenomic data of the soil microbiota cultured under suitable (30℃) or stressful (37℃) conditions, we show how the microbial interaction network responds to temperature stress. While the genera that persisted only under the suitable condition gave fewer positive effects, the genera that appeared only under the stressful condition received more positive effects in agreement with SGH. However, temperature changes also induce reconstruction of a community network, leading to an increased proportion of negative interactions at the whole community level. The anti-SGH pattern can be explained by the stronger competition caused by increased metabolic rate and population densities.Â
