TABLE 1.
Linear mixed effects model for the effect of evolutionary treatment on adult female body size across three generations (G0, G1, G2), with ancestral G0 cultures reared within feeding blocks of four.
| Effect | Df | Mean squares | F | p |
|---|---|---|---|---|
| Treatment | 1, 11.67 | 5.69 × 10−1 | 0.16 | 0.70 |
| Generation | 2, 691.43 | 3.20 × 10−4 | 287.52 | <10 −15 |
| Block | 4, 11.76 | 1.95 × 10−3 | 0.98 | 0.45 |
| Treat × Gen | 2, 686.54 | 1.01 × 10−2 | 5.10 | 0.006 |
| Culture (Treat) | 1.93 × 10−3 |
Note: p values are provided for tests of interest, significant effects are specified in bold, and random effect is specified in italics. Degrees of freedom (df) reported as numerator df, denominator df. n low = 9 and n high = 10.
