Narrow Margins: Aerobic Performance and Temperature Tolerance of Coral Reef Fishes Facing Extreme Thermal Variability

<b>Data Overview</b><br>Data from intermittent flow respirometry, critical thermal maxima, and critical thermal minima experiments associated with Vaughan et al. 2025. All experimental datasheets include the species name (Cnovi = <i>Cheilodipterus novemstriatus</i>, Epul = <i>Ecsenius pulcher</i>, and Sghan = <i>Scolopsis ghanam</i>) as well as their acclimitisation temperature (18, 22, 27, 31.5, or 35.5 Celsius), body mass in grams (MassG), and population origin (AG = Arabian/Persian Gulf, GO = Gulf of Oman).<br>The units for the critical thermal limits data and the thermal safety margin data are degrees Celsius. The units for the respirometry data are mgO₂ kg^-1 hour^-1.The respirometry data have been corrected for background respiration as described in Vaughan et al. 2025.Please note that two versions of the respirometry data have been uploaded. 'All_resp_data.csv' contains the SMR, MMR, and AS data. 'All_species_SCALED_MO2_data.csv' contains the same data but scaled to remove the effect of body mass using the R-script available in Johansen et al. 2024.<br><b>References</b><br>Johansen, J.L., Mitchell, M.D., Vaughan, G.O., Ripley, D.M., Shiels, H.A. and Burt, J.A., 2024.
