Table 1. Observed and expected richness of seed species dispersed by brown howlers in Atlantic forest fragments in southern Brazil.
| Fragment | Sobs | Nonparametric richness estimator | ||||
|---|---|---|---|---|---|---|
| Chao1-bc | ACE | Jack1 | Mean | SC (%) | ||
| S1 | 53 (39, 28) | 56.5 | 58.7 | 61.0 | 58.7 (2.3) | 90.2 |
| S2 | 53 (37, 30) | 58.1 | 62.7 | 62.0 | 60.5 (2.5) | 87.0 |
| S3 | 30 (23, 14) | 35.0 | 42.8 | 36.0 | 37.9 (4.2) | 79.1 |
| L1 | 39 (30, 24) | 42.0 | 45.2 | 45.0 | 44.1 (1.8) | 88.5 |
| L2 | 40 (33, 23) | 67.5 | 73.2 | 51.0 | 63.9 (11.5) | 62.6 |
| L3 | 43 (35, 26) | 45.5 | 46.5 | 48.0 | 46.7 (1.3) | 92.1 |
Observed species richness (Sobs) and the number of genera and families are indicated in parentheses. The three richness estimators were: bias corrected form for the Chao1 (Chao1-bc), Abundance-based Coverage Estimator (ACE), and 1st order Jackknife (Jack1) that uses the number of singletons to estimate the number of undetected species. The mean (±SD) of the three richness estimators is also indicated. The sample completeness (SC) was calculated as the percentage of expected richness (i.e. observed/mean of estimator x 100) covered by sampling effort.
