Table 1 Full statistical models examined.
Model | Hypothesis and predictions | Data set | Response variable | Fixed factors | Interaction | Random factors | No of replicates |
|---|---|---|---|---|---|---|---|
1 | Hypothesis 1, prediction i | Mating season | Total no of male mating partners | Focal female AGD + focal female serum T + focal female body weight + no of males within social group | (Focal female AGD x focal female serum T x n° of males within social group) | Year + SGID + female ID | n = 160. Include all females studied during mating season, that in spring weaned at least one offspring |
2 | Hypothesis 1, prediction ii | Mating season | No of male mating partners within social group | Focal female AGD + focal female serum T + focal female body weight + no of males within social group | (Focal female AGD x focal female serum T x n° of males within social group) | Year + SGID + female ID | n = 118. Include all females studied during mating season, that were members of social group with at least one male member, and that in spring weaned at least one offspring |
3 | Hypothesis 1, prediction iii | Mating season | No of male mating partners outside social group | Focal female AGD + focal female serum T + focal female body weight + no of males within social group | (Focal female AGD x focal female serum T x n° of males within social group) | Year + SGID + female ID | n = 160. Include all females studied during mating season that in spring weaned at least one offspring |
4 | Hypothesis 2, prediction iv | Mating season | Litter size at weaning | Focal female AGD + focal female serum T + focal female body weight + no of male mating partners attained | (Focal female AGD x focal female serum T x n° of male mating partners attained) | Year + SGID + female ID | n = 160. Include all females studied during mating season that in spring weaned at least one offspring |
5 | Hypothesis 3, prediction v | Nursing season | Litter size at weaning | Focal female AGD + focal female serum T + focal female body weight | (Focal female AGD x focal female serum T) | Year + SGID + female ID | n = 308. Include all females studied during nursing season |
