Distribution of mean estimates for three key thermal traits: lower thermal limits (inner heat map), thermal preference (central heat map), and upper thermal limits (outer heat map). The number of estimates for each species is displayed as histograms, scaled on a log2(x + 1) axis for clarity. The histograms are colour-coded according to the life stage assessed in the experiments, with the category “juveniles” comprising larvae, metamorphic, and juvenile stages. Gray colour represents missing data. The phylogeny relationships are based on the consensus tree from⁸¹. a. Notophthalmus viridescens, b. Dendropsophus ebraccatus, c. Hyla cinerea, d. Pleurodema thaul, e. Ceratophrys cranwelli, f. Craugastor longirostris, g. Rana pipiens, h. Xenopus laevis, i. Plethodon cylindraceus.
