Biodiversity Effects on Plant Stoichiometry
In the course of the biodiversity-ecosystem functioning debate, the issue of multifunctionality of species communities has recently become a major focus. Elemental stoichiometry is related to a variety of processes reflecting multiple plant responses to the biotic and abiotic environment. It can thus be expected that the diversity of a plant assemblage alters community level plant tissue chemis...
متن کاملResponse of plant nutrient stoichiometry to fertilization varied with plant tissues in a tropical forest
Plant N:P ratios are widely used as indices of nutrient limitation in terrestrial ecosystems, but the response of these metrics in different plant tissues to altered N and P availability and their interactions remains largely unclear. We evaluated changes in N and P concentrations, N:P ratios of new leaves (<1 yr), older leaves (>1 yr), stems and mixed fine roots of seven species after 3-years ...
متن کاملPlant allometry, stoichiometry and the temperature-dependence of primary productivity
Aim While physical constraints influence terrestrial primary productivity, the extent to which geographical variation in productivity is influenced by physiological adaptations and changes in vegetation structure is unclear. Further, quantifying the effect of variability in species traits on ecosystems remains a critical research challenge. Here, we take a macroecological approach and ask if va...
متن کاملPlant Growth – Stoichiometry and Competition Theory Development in Ecosystem Ecology
Knecht Billberger, M. F. Plant growth – stoichiometry and competition. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-7073-0. In four different studies, this thesis addresses issues concerning plant nutrition and growth from a theoretical perspective. Terrestrial plants require nutrients, water, light and space for their existence. All of these resources may be limiting for growth, however ...
