Pedodiversity-area relationships for islands

Our objectives were examine whether the pedotaxa-abundance distributions conform to abundance distribution models and how pedorichness-area data fit diversity-area models considered by ecologists. The study area selected was the Aegean Islands. Standard statistical methods were used to gauge the abundance distribution models (Smirnov-Kolmogorov test of goodness of fit) and pedorichness-area models (linear regression, log-log or semi-log). The Smirnov-Kolmogorov test of goodness of fit indicated that the logseries and the broken stick distribution models should be rejected, whereas the geometric and lognormal models were not rejected (P<5%) Pedorichness-area relationships conform to a power law whose exponent is close to 0.25, as ecological literature predicts. No significant difference was observed between the abundance distribution models and the diversity-area relationships followed by biodiversity and pedodiversity data in similar situations.
