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).
