Effects of morphology and stand structure on root biomass and length differed between absorptive and transport roots in temperate trees
Absorptive and transport roots (diameter ≤ 2 mm) are closely related to soil resource uptake for plant growth, carbon budget and nutrient cycling in forest ecosystems, but how and why the relative share of roo...

Linkage of root morphology to anatomy with increasing nitrogen availability in six temperate tree species
Fine root morphological traits are generally changed under soil nitrogen (N) enrichment, however, the underlying mechanism and functional significance are still not well understood. Our aims were to investigat...

Effects of continuous nitrogen addition on microbial properties and soil organic matter in a Larix gmelinii plantation in China
Continuous increases in anthropogenic nitrogen (N) deposition are likely to change soil microbial properties, and ultimately to affect soil carbon (C) storage. Temperate plantation forests play key roles in C ...
