Comparison of Critical Thermal (CT) limits for Poecilia caucana (Pc, grey polygon) and a sample of species with CTmin and CTmax data available in the literature. Polygons are formed by two vertical lines representing the CT tolerance ranges observed at the lowest and highest acclimation temperatures used in each study. The polygons have an arbitrary width that does not reflect the range of acclimation temperatures used among different studies. The top and bottom lines of each polygon join, respectively, the CTmax and CTmin values for each species. Three species (N, Ns, and P) having data for only one acclimation temperature are represented by vertical lines. Pf = Prochilodus scrofa (currently Prochilodus lineatus ), fry, and Ps = P. scrofa , adults (Barrionuevo & Fernandes, 1995Barrionuevo, W. R. & M. N. Fernandes. 1995.
