每天的生殖监测整个生命的1000个女性地中海果蝇（Ceratitis capitata）。由于雌性地中海果蝇的平均寿命为35.6天，一生中产下740个卵，因此整个数据集由分布在35，600个飞行日的约740，000个卵的信息组成。描述的结果包括在年轻（小于或等于30天），中间（31-60天），和老年人（61-90天）的年龄，个体寿命剥落和终身生殖之间的关系，死亡的分布无蛋层与蛋层，和密度图相对于终身生殖和寿命剥落的每日产蛋量。更令人惊讶的结果之一是，年轻女性（所有年龄均在30岁以下）所产的卵总数与随后的繁殖和寿命之间缺乏相关性。对其他物种和群体的生殖数据分析的技术和概念的影响进行了简要讨论。
Daily reproduction was monitored throughout the lives of 1000 individual female Mediterranean fruit flies (Ceratitis capitata). Inasmuch as the average female medfly lived 35.6 days and laid 740 eggs ill hel lifetime, the overall data set consisted of information on around 740,000 eggs distributed over 35,600 fly-days. Results described include the frequency distributions of eggs/day at young (less than or equal to 30 days), middle (31-60 days), and older (61-90 days) ages, the relationship between individual life spall and lifetime reproduction, the distribution of deaths for non-egg layers versus egg layers, and density plots for daily egg production relative to both lifetime reproduction and life spall. One of the more surprising results,vas the lack of correlation of the total number of eggs laid by females at younger ages (all ages under 30) and subsequent reproduction and life span. Technical and conceptual implications for analyses of reproductive data on other species and groups are briefly discussed.
