ECOLOGICAL STOICHIOMETRY: A SCIENCE TO EXPLORE THE COMPLEXITY OF LIVING SYSTEMS C, N and P stoichiometric characteristics of different root orders for three dominant tree species in subalpine forests of western Sichuan, China. Effects of Nitrogen and Phosphorus Additions on Nutrients and N:P Stoichiometry in Dwarf Lilyturf Roots Influence of grazing disturbance on stoichiometric characteristics of alpine Rhododendron shrublands underground soil nutrient pool Adaptive adjustment to nutrient absorption and accumulation of Phyllostachys rivalis rhizome-roots under waterlogged conditions
