<p>Data for a Journal article titled 'Male Mediterranean fruit flies prefer warmer temperatures that improve sexual performance' published on Journal of Thermal Biology, Volume 108, August 2022, 103298.</p> <p>The dataset contains R scripts and digital data on the thermal preference of virgin and sexually mature Mediterranean fruit flies (<em>Ceratitis capitata)</em>, that test the idea of sex-related variation in thermal preference results from different reproductive benefits for each sex.</p> <p>Three specific hypotheses were tested:</p> <p><strong>Hypothesis 1.</strong> Sexually mature, virgin male <em>C. capitata</em> prefer higher temperatures to facilitate increased calling behaviour<br> <strong>Hypothesis 2.</strong> Sexually mature, virgin male <em>C. capitata</em> prefer higher temperatures to facilitate sexual performance</p> <p><strong>Hypothesis 3.</strong> Female <em>C. capitata</em> prefer lower temperatures to improve reproductive output through more efficient conversion of food to eggs.</p> <p>R scripts used to analyse the accompanying data files are:</p> <p><strong>Gradients.R</strong>: Gradients.csv; Temp_VP.csv; Temp_Evaporation.csv</p> <p><strong>Thermal pref_male performance.R</strong>: Preference_data.csv; Male_calling.csv; Mating.csv</p> <p><strong>Thermal pref female performance.R</strong>: Survival.csv; Eggs_cumulative.csv; Eggs_total.csv; Female_consumption.csv<br> <strong>Thermal pref female biochem.R</strong>: Female_biochem.csv<br> </p>
