Endophytic diversity profiles.

<p><i>Aeschynomene fluminensis</i> (red line) and <i>Polygonum acuminatum</i> (black line) of environments with (+PHg and +AHg) (●) and without (-PHg and -AHg) (▲) mercury, using the Hill Series. For the parameter <i>a</i> = 0, the diversity value is equal to the number of species in the sample. For the <i>a</i> tending to 1, the diversity value is equivalent to the Shannon index. For <i>a</i> = 2, the value equals the Simpson index.</p
