Table 2.

Results of the Monte Carlo simulations carried out to determine whether intratype variation in ecotope structural characteristics for the seven landscapes belonging to ecomosaic type 7 is less than that expected by chance

Supervised classification Unsupervised classification
Mean patch size 84* 82*
Mean patch shape 100 100
Mean nearest-neighbor distance 100 100
Ecotope diversity: Shannon index 100 100
Ecotope diversity: Richness 100 100

Values in the Table represent the number of times out of 100 that intratype variance in the structural parameter specified by the column heading, using the classification method specified by the row heading, was less than the variance for a randomly assembled set of seven landscapes. If a value is greater than 95, the null hypothesis that landscapes belonging to different ecomosaic types do not differ in their ecotope structure is rejected at a 95% confidence level.
