Diversity indices of T-RFs generated by 16S rRNA amplification and MspI digestion of Luquillo Experimental Forest, P.R., soils

Index	Valuea under the indicated conditions
	Field	Anoxic	12 h	4 day	Aerobic
Richnessb	139 a	74 c	25 d	92 b	76 bc
Evennessc	0.82 a	0.97 b	0.98 b	0.87 a	0.83 a
Shannon diversityd	4.0 a	2.7 b	2.8 bc	3.2 c	2.7 bc
Indicator valuee	42.6 a	5.3 b	19.7 c	36.5 d	5.9 b

^aSignificant treatment differences are indicated by different lowercase letters.

^bMean number of unique terminal fragments per treatment, a measure of diversity.

^cEquitability, equal to Shannon index/ln richness.

^dDiversity of terminal fragments in a sample unit.

^eAn index of both T-RF frequency and abundance, higher values indicate better indicator T-RFs.
