Figure captions
Figure 1. A community network in which the distances between all three
species are identical, which results in three possible minimum spanning
trees (MSTs) and multiple FEve estimates for the same community.
Figure 2. In these communities, two of the three species are equally
distant in both communities (d 12 =d 23 = d ) with a distance that is smaller
than the third distance (d 13). If the abundances
of the three species are \(w_{1}=1\), \(w_{2}=2\) and \(w_{3}=3\),
then FEve = 0.75), even though community B seems much more functionally
irregular than community A.
Figure 3. This community consists of three species in whichd 23 is larger than d 13 andd 12. The abundances (w ) and distances
result in values of \(\text{EW}_{12}=\text{EW}_{13}=\frac{1}{6}\ \),\(\text{PEW}_{12}=\text{PEW}_{13}=0.5\), and FEve = 1.
Figure 4. Variability of FEve estimates for the actual abundances of
eleven virulence phenotypes of P. graminis , and the Y- and Z-
modification of abundances (see Table 3 for details).
