τ and ‘ratio-to-p’ values for all Nasonia strains in constant light (LL).

Tau (τ, in hours), ratio-to-p, standard error (SEM), and number of wasps used are indicated for each strain. Species means are indicated in bold (except for column ‘Total wasps’, which indicates the total amount of wasps per each species). Tau means are weighted and, respectively, non-weighted (in brackets). For significant differences see figures 4 and 5.
