Nicotine resistance data (Figure 1): from Trade-offs between cost of ingestion and rate of intake drive defensive toxin use

Raw data of A4 and A3 nicotine resistance is stored in the file titled “nicotine_media_fly_survival.csv”. Each row of the datafile represents survival data from a single vial of <i>Drosophila</i> melanogaster. The columns titled strain, replicate, and dose indicate each vial's fly strain, nicotine concentration (in mM), and replicate number. The alive column indicates the number of flies that survived nicotine exposure out of 20 initial individuals, and the dead column indicates how many died. The percent column is percent survival (alive/20 *100).

A4与A3尼古丁抗性的原始数据存储于名为“nicotine_media_fly_survival.csv”的文件中。该数据文件的每一行对应单管黑腹果蝇（Drosophila melanogaster）的存活实验数据。列名为strain（品系）、replicate（重复次数）与dose（处理剂量）的三列，分别指示各实验管的果蝇品系、尼古丁浓度（单位为mM）以及重复实验编号；alive（存活数）列代表初始20只果蝇经尼古丁暴露后的存活个体数量，dead（死亡数）列则记录了死亡个体数；percent（存活率）列为存活率百分比，计算公式为（存活数/20）×100。
