been examined, by using t-test in exposure and variance analysis, if there is any difference between these sub-groups. t-test results for exposure factor are presented in Table 6. As it can be seen, since the Sig. (p) values of t-test were p>0.05, H _{0} hypothesis is accepted. In other words, „there is no statistically significant difference between 2 different exposure groups and aboveground, belowground, and total amount of biomass.“The plot areas having different altitudes were clustered into 4 groups as 400-600m, 601-800m, 801-1000m and 1001-1200m. The similarities and differences between altitude groups and aboveground, belowground, and total biomass were examined by using independent sample one-way variance analysis (ANOVA). Since the significance value (Sig. p) of the table presenting the results obtained from analyses was higher than 0.05, it was concluded that there was no statistically significant difference between altitude level and mentioned variables (Table 7). The similarities and differences between the subgroups created based on mean vegetation height and the aboveground, belowground, and total biomass were examined by using independent sample one-way variance analysis (ANOVA). Since the significance value (Sig. p) of the table presenting the results obtained from analyses was higher than 0.05, it was concluded that there was no statistically significant difference between top height and relevant variables (Table 8). By calculating the mean ages from the stem sections of maquis components cut at the ground level in sampling areas, 4 groups (10-20, 21-30, 31-40 and 41-50 ages) were established. Since the significance value (Sig. p) of the table presenting the results obtained from analyses was higher than 0.05, it was concluded that there was no statistically significant difference between age groups and mentioned variables (Table 9).
