McKenzie; Evidence that tolerance of acute warming declines with increasing body mass within fish species. <i>J Exp Biol</i> 1 September 2025; 228 (17): jeb250612. doi: https://doi.org/10.1242/jeb.250612Description : The objective of the study was to test the theory that larger individuals are more sensitive to warm temperatures, proposed as a result of limitations in their capacity to provide oxygen for aerobic metabolic activites. The study was performed in four populations of fish, reared or wild (reared European seabass <i>Dicentrarchus labrax</i>, wild European seabass <i>D.labrax</i>, wild Gilthead seabream <i>Sparus aurata</i>, and reared Nile tilapia <i>Oreochromis niloticus</i>), using a critical thermal maximum for swimming (CTS_max) protocol.Nile tilapia data :The Nile tilapia data is from from Blasco et al. (2022) freely available at Mendeley: doi:10.17632/npmchftsjf.1. Fish performed similar protocols as for seabass and seabream.<br><b>readme</b><b>.docx</b> - Contains the column names and definitions of file dataframe_MS_Evidence_that_thermal_tolerance.xlsx<b>dataframe_MS_Evidence_that_thermal_tolerance</b><b>.xlsx</b> - Represents datafile associated to Rscript_Evidence_that_tolerance_final.r<b>Rscript_Evidence_that_tolerance_final</b><b>.r</b> - Represents analysis script<b>session_info</b> - Represents R environment in which the analysis was conducted
