Table 4. Results of the exploratory factor analysis.
| Alpha Diversity Measure | “Richness” Factor Loading | “Evenness” Factor Loading | h2 | Final Categorization |
|---|---|---|---|---|
| Fisher alpha | 1.0 | 1.0 | Richness | |
| Faith pd | .91 | .84 | Richness | |
| Shannon | .86 | .89 | Richness | |
| Enspie (ENS) | .81 | .90 | Richness | |
| Menhinick | .77 | .74 | Richness | |
| Strong* | -.80 | .81 | Evenness | |
| Simpson e | .93 | .90 | Evenness | |
| Heip e | .92 | 1.0 | Evenness | |
| Lladser pe | .55 | .40 | Evenness |
h2 = proportion of variance of each measure explained by the factors
* denotes measure that was “reverse coded” prior to z-score conversion on the basis of direction of factor loading and evaluation of relevant literature and mathematical expression; factor loadings > .5 shown.
