On the other hand, representative units and sampling techniques are those that have relative densities (individuals per sample) that present the same variation as the absolute density (individuals per plant or vine).
These data were used to determine the absolute density, relative density of cacao trees, rubber trees, shade trees, wealth, Shannon-Weaver diversity index (H').
The results indicate that the absolute density and the bulk density of the tested powder are 2.69 g/[cm.sup.3] and 0.61 g/[cm.sup.3], respectively.
This approach takes the standard deviation of average relative velocity and average of absolute density difference with respect to its neighboring, in addition to the location and direction of movement into consideration in the clustering process.
For the DUSI reading, the Absolute Density of Problems (ADP) is calculated, which refers to the intensity of the problem in each area; the Relative Density of Problems (RDP) is the percentage contribution of each area in total problems; and the General Density of Problems (GDP) indicates the severity of the problems in general (Tarter, 1990; De Micheli & Formigoni, 2000).
Evaluate the relation between use-value and their respective structural parameters (importance values, absolute density and frequency) in the ecosystem; 3.
According to Mueller-Dombois and Ellenberg (1974) and Martins (1993), the following quantitative phytosociological parameters were calculated: Absolute Density (DAi) and Relative Density (DRi), Absolute Frequency (FAi), Relative Frequency (FRi), Absolute Dominance (DoAi), Relative Dominance (DoRi), Importance Value Index (IVI) and Importance Value Coverage (IVC).
The first stage of vegetation analysis to determine the type and number of parameters flora with absolute density and relative density of the formula [8]:
Both methods provide indices of relative abundance: it is impractical in tall forest to accurately estimate absolute density whereas tracking tunnel results are related to the activity of weta.
Number of points and quadrates with each species, total stand density, absolute density, basal area, as well as relative frequency, dominance, density and importance value for each species were calculated following Cintron & Schaeffer-Novelli (1984).
