Data statistical analysis
Firstly, normality of data (SSB density, species richness, diversity indices and similarity between AGV and SSB) was examined using the Kolmogorov-Smirnov test and homogeneity of variance using Levene’s test. Total seed density was transformed toto meet the normal distribution. To evaluate the effect of shrub species on SSB properties one-way ANOVA and LSD mean comparison tests were used. All statistical analyses were performed in the SPSS software ver. 16.
