Figure 1.
(a) Variation in BCH over time in the four groups. Lines and shadowed areas represent fitted GAMMs and 95% confident intervals respectively. (b) Means (symbols), medians and quantiles (boxes) for each group in the three seasons. Vertical segments indicate significant differences from the posthoc comparisons between groups in each season, as revealed by the LMM. Only comparisons within seasons are shown here. ·P = 0.06; *P < 0.05; **P < 0.01; ***P < 0.001. Examples of short-term changes in BCH of four individuals from (c) “constant temperature”, (d) “natural temperature”, (e) “natural late” and (f) “free-ranging”. Dots connected with dashed lines indicate repeated measurements of BCH for each individual. Solid lines and shadowed areas represent fitted GAMMs and 95% confident intervals respectively, each individual’s panels includes the curve corresponding to all animals from its group. (g) Repeated measurements of BCH in a long lived individual illustrating a second shrink-regrowth cycle. Vertical black lines at the left of each panel (c–g) represent the technical error of measurement as calculated in Lázaro et al.10.
