Table 1 Comparison of species richness across two elevational zones in Gomo forest. Mean ± SD species richness is shown for the forest-dependent and forest generalist assemblage in each zone. P-values are Bonferroni-adjusted to account for multiple testing. Text in bold indicates a statistically significant difference across zones
| Bird diversity indices | Mid-zone (Mean ± SD) | High-zone (Mean ± SD) | Test statistic |
|---|---|---|---|
| Forest-specialist richness (n = 18) | 9 ± 2 | 7 ± 2 | W = 15.5, p = 0.15 |
| Forest generalist richness (n = 16) | 11 ± 1 | 8 ± 1 | t = − 4.55, df = 10.02, p = 0.01 |
