The quality layers were classified in four quantitative and qualitative classes as shown in Table 2.
Since the IMBP produces only qualitative classes such as "excellent" or "poor", a quantification method is adopted in order to obtain a quantitative value that can be easily compared to the crisp scores produced by the fuzzy index.
Moreover, the conventional assessment of water quality based on quality thresholds prescribed by the Moroccan legislation (IMBP) gives the results in the form of qualitative classes, such as "good", "average", or "poor", and therefore the information provided by the index is very limited.
Four qualitative classes of specificity for the cyclohexadienyl substrate populate the TyrA superfamily of homologs (Fig. 1).
When the trait of interest is quantitative, as in this case (estrous behavior quantified as heat score), the grouping of individuals into qualitative classes dilutes the available information.
Structural loss or fragmentation in SDTs is widely documented in qualitative decay class descriptions [[10, 14, 16, 17], and many others] and in studies of SDT longevity [5]; however, there are few quantitative references by decay class [13].

Density in terms of occurrence and water surface occupied was expressed in four qualitative density classes.
For this study, a pool of 412 potential predictors was assembled, which included qualitative location classes, elevation, land-surface derivatives (with a wide range of analysis scales), hydrologic indicators, as well as proximal and remote sensing (from multiple sources with a variety of resolutions).
The judgement criterion was a qualitative, six-class (0 5) variable for each group of subjects.
