Mean ± SE of CORT levels (a–c), and LS means ± SE of log(developmental time, days from G25) (d–f) and log (mass in g) (g–i), across three larval developmental stages (G32, left panel, G38, middle panel, and G42, right panel) in Rana arvalis. Tadpoles from the Acid (TT), Neutral (RD) and Intermediate (BS) origin population were reared in Acid (4) or Neutral (7) pH treatment across two rearing Blocks (A: morning sampling/warmer; B: afternoon sampling/colder). Sample size was N = 8 except for the following cases: a) TT4B, TT7A and TT7B: N = 7; b) RD4B and BS4B: N = 6, BS4A and TT4B: N = 7; c) BS4B and TT4B: N = 6, TT7B: N = 7; f) TT4B and TT7B: N = 7, BS7B: N = 9; g) BS4B: N = 7; i) TT4B and TT7B: N = 7, BS7B: N = 9 (see Methods for details)
