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

Data OverviewData 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 = Cheilodipterus novemstriatus, Epul = Ecsenius pulcher, and Sghan = Scolopsis ghanam) 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).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.ReferencesJohansen, J.L., Mitchell, M.D., Vaughan, G.O., Ripley, D.M., Shiels, H.A. and Burt, J.A., 2024.
