- Divergent effects of litter manipulation and nitrogen enrichment on aboveground-belowground stability are mediated by soil biodiversity in contrasting grassland states (2026) · Journal Of Plant Ecology · doi
However, the interactive effects of litter management and nitrogen (N) enrichment on ecosystem stability remain unclear, especially when jointly considering above- and belowground processes.

Litter inputs can influence soil respiration directly through labile C availability and, indirectly, through the activity of soil microorganisms and modifications in soil microclimate; however, their relative contributions and the magnitude of any effect remain poorly understood.
