Distributions of fine root length and mass with soil depth in natural ecosystems of southwestern Siberia
Aims Forest-steppe and sub-taiga, two main biomes of southwestern Siberia, have been predicted to shift and spread northward with global change. However, ecological projections are still lacking a description of belowground processes in which fine roots play a significant role. We characterized regi...
