H.  aDimension and production relations of trees and shrubs in the brookhaven forest, New York.h[electronic resource]  c1968  aAbstract: A system of intensive analysis of weight, production and surface relationships was applied to seven species of trees and shrubs in the Brookhaven oak-pine forest. Distributions of biomass and net production among major plant parts are discussed in terms of regressions and of averages for the sets. Study of allometric relationships for individuals of all species combined show trends in the dimensional relations of plant parts which shift gradually and continuously with plant size from small shrubs to forest trees. Regressions within species may be effectively used to estimate weight, production and surface relations of shrub communities and forests. For this purpose, and in relation to studies of gaseous exchange, nutrient circulation and dominance-diversity structure, the system of analysis has substantial usefulness for the study of shrubland and forest eco-systems.  aShrubs  aTrees  aArbusto  aÁrvore  aEcologia  aPlanta  aProdução  aRadiation effects  aRadiation injuries1 aWOODWELL, G.
