%0 Journal Article %T A Consideration of the Constancy of Biomass Density in Plant Populations Undergoing Self-Thinning %A Kazuharu Ogawa %J International Journal of Ecology %D 2007 %I Hindawi Publishing Corporation %R 10.1155/2007/54762 %X The constancy of biomass density was considered in an entire plant population p by combining two adjacent populations p1 and p2 for which the self-thinning rule is assumed to be satisfied independently and each biomass density is also assumed to be the same constant value. Under these assumptions, the biomass density d in a population p was formulated as d=c((km−α %U http://www.hindawi.com/journals/ijeco/2007/054762/abs/
