Heat-tolerance limits (CT max ; inner heat map), TSM (outer heat map), and the number of overheating events (days) averaged across each species distribution range (histograms) ( n =5,177 species). The pink bars refer to species for which there was previous knowledge ( n =521), and the grey bars refer to entirely imputed species ( n =4,656). This figure was constructed assuming ground-level microclimates occurring under 4 C of global warming above pre-industrial levels. Phylogeny is based on the consensus of 10,000 trees sampled from a posterior distribution (described previously 60 ). Highlighted species starting from the right side, anti-clockwise: Neurergus kaiseri , Plethodon kiamichi , Bolitoglossa altamazonica , Cophixalus aenigma , Tomaptera cryptotis , Lithobates palustris , Allobates subfolionidificans , Phyzelaphryne miriamae , Barycholos ternetzi , Pristimantis carvalhoi , Pristimantis ockendeni , Boana curupi , Teratohyla adenocheira and Atelopus spumarius .
