“Site” indicates whether the data are from colonies within the CSU (“CSU”) or outside in ambient conditions (“out”). “Interval” indicates the 6-d interval, with each interval consisting of two sequential 3-d subsets; during interval “7–12 d” colonies were in total darkness; during intervals “25–30 d” and “40–45 d” colonies were subject to a 12 l:12D light regime; and during interval “post” colonies were in ambient conditions outside the CSU. “Watson” indicates the value of the Watson’s test for homogeneity on two samples of circular data, and “P” refers to the probability of the value. N = 32 for each group within the CSU; N = 30 for the post-CSU temperature group and N = 26 for the post-CSU CO₂ group (see text for details). Significant contrasts are in bold.
