| Recent debate has considered the relative density of trees within these primeval woods or wildwoods. |
| No natural reactors exist today, as the relative density of fissile uranium has now decayed below that needed for a sustainable reaction. |
| Peak and relative density counts were combined to arrive at density estimates for each species in each year at each blind. |
| I used relative basal area as a measure of importance, because that value is less influenced by differences in sampling procedure than is relative density. |
| We used seedling density values to calculate the relative density of each species. |
| To apply this test, the relative density or specific gravity of the sample must be determined. |
