Rhythm analysis of emergence of O. bicornis under different environmental conditions (first emergence experiment).
| Treatment | Emergence period (P) [h] | Rhythmicity index (RI) | Maximum entropy spectral analysis (MESA) [h] |
|---|---|---|---|
| DD total | 23.8 | 0.29 | 24.1 |
| DD male | 23.8 | 0.24 | 23.9 |
| DD female | 22.8 | 0.22 | 23.6 |
| TC total | 24.0 | 0.64 | 23.8 |
| TC male | 24.0 | 0.56 | 24.5 |
| TC female | 24.0 | 0.58 | 24.8 |
| LD total | 24.8 | 0.09 (n.s.) | 23.8 |
| LD male | 22.5 | 0.11 | 22.0 |
| LD female | 24.2 | 0.08 (n.s.) | 25.1 |
Table shows emergence period (P) calculated in the autocorrelation function, rhythmicity index (RI) as measurement of rhythm strength and emergence period calculated with maximum entropy spectral analysis (MESA) for the whole population as well as male and female subpopulation. Treatments were conducted under different environmental conditions: DD (constant conditions), TC (temperature cycles of 12 h high and 12 h low temperature) and LD (cycles of 12 h light and 12 h darkness). RI > 0.3 = highly significant, 0.1 < RI < 0.3 = significant, RI < 0.1 = not significant.
