What is it about?
Plants may invest relatively strongly in leaves, stems or roots, but not in all organs, Here we first analyse how the environment affects biomass allocation, by calculating dose-reponse curves for 12 environmental variables. Second, we quantitatively analyse differences in allocation among different species, by means of meta-analysis.

Why is it important?
Nutrient availability strongly affect biomass allocation, followed by light and temperature. Most other environmental variables only have a marginal effect. Grasses do have a higher fraction of biomass in roots than deciduous herbaceous species, whereas woody gymnosperms have a higher allocation to leaves than woody angiosperms.
