Inverse effects of soil moisture and litter quality on litter decomposition along a gradient from hyper‐arid to temperate climate

Journal of Ecology, Volume 114, Issue 1, January 2026.
We hypothesized that litter decomposition (H1) and litter quality (H2) increase with increasing soil humidity, therefore litter from the wetter sites to have the highest litter quality and decompose fastest in each site, and fastest on the wet end of the gradient (H3).
