Is the microbial community in a soil with reduced catabolic diversity less resistant to stress or disturbance? by Degens, Bradley P., Schipper, Louis A., Sparling, Graham P., Duncan, Louise C.

“…Microbial catabolic diversity can be reduced by intensive land-uses, which may have implications for the resistance of the soils to stress or disturbance. We…”

Changes in aggregation do not correspond with changes in labile organic C fractions in soil amended with 14C-glucose by Degens, Bradley, Sparling, Graham

“…Dry-sieved aggregates (> 2 mm, 1–2 mm, 0.5–1 mm, 0.25–0.5 mm and < 0.25 mm) were amended with 14C glucose at 615 ng C g −1 soil (low glucose, LG) or 2457 ng C…”
