a Modification Y of abundances of two phenotypes.
b Modification Z of abundances of two phenotypes; the total number of individuals was not changed.
c Twenty-four different MSTs are possible with one of these edges. The multiple MSTs resulted in ten, twenty-four, and eighteen different FEve values for actual abundances, Y-modification, and Z-modification, respectively. Variability of FEve estimates is shown in Fig. 4.
Table 4. (A) Eleven microsatellite genotypes of P. triticina (Pt): pairwise distances, abundances and MST attributes. The weights of the edges between each pair of nodes is equal to the distance between those genotypes. To show the effects of variation in abundances, besides the actual values, we calculated FEve for two instances of altered values. (B) Estimates of functional evenness FEve.
