Webb1 mars 2000 · On hillside sites in this high diversity forest, maximum dimensions were usually <10-m height, 4-m crown diameter, and 0.3-m trunk diameter. The relationship of height to trunk diameter was characterized by an asymptotic, three-parameter model. Crown diameter was a linear function of trunk diameter. The parameter values for both … WebbFisher's principle is an evolutionary model that explains why the sex ratio of most species that produce offspring through sexual reproduction is approximately 1:1 between males and females. A. W. F. Edwards has remarked that it is "probably the most celebrated argument in evolutionary biology".. Fisher's principle was outlined by Ronald Fisher in his …
