Table 2.

Volume, fiber length and PCSA of the rectus cervicis muscle in paedomorphic and metamophic I. alpestris. Values are mean ± 1 standard deviation. The Mann-Whitney-U tests compare values between the two morphs. Significance level was adjusted to p ≤ 0.017 after simultaneous Bonferroni correction.
