a Simulated absolute abundances.
b There are four different MSTs with one of these edges. These MSTs resulted in four different FEve values: 0.533, 0.553, 0.612, 0.635.
Table 3. Eleven virulence phenotypes of P. graminis (Pgt): pairwise distances, abundances, MST attributes, and estimates of functional evenness FEve. The weights of the edges between each pair of nodes is equal to the distance between those phenotypes. To show the effects of variation in abundances, besides the actual values, we calculated FEve for each of two pairs of altered values.
