Mesocosm experiment

These data were collected during the mesocosm experiment described in "Keystone nonconsumptive effects within a diverse predator community" by Meadows et al. 2017. A description of each column follows: 1- Source: treatment groups; 2- Exposure: C=caged mosquito larvae, NC= exposed mosquito larvae; 3- Sex: sex could only be determined for (most) adult mosquitoes; 4-Tp: days to pupation i.e. larval development period; 5- Longevity: adult mosquito longevity (eclosion-death, in days); 6- Density: total number of predators in mesocosm; 7- Aquarius: number of Aquarius in mesocosm; 8- Beetle: number of Agabus + Tropisternus beetles in mesocosm; 9- Notonecta: number of Notonecta in mesocosm; 10- Aeshna: was Aeshna present in the community? Yes or No for predator treatments, Control if no predator (or Aeshna, by extension); 11-H: Shannon's H calculation for predator community evenness (99 entered for control to easily subset predator only treatments); 12- Cslong: sex-standardized adult longevity (see Meadows et al. Supp Info for calculation); 13- Winglength: adult winglength (in mm)本数据集采集自Meadows等人2017年发表于《多样捕食者群落内的关键种非消耗效应》（原英文标题：Keystone nonconsumptive effects within a diverse predator community）的中型实验围隔（mesocosm）实验。各字段的详细说明如下： 1. 来源（Source）：实验处理组； 2. 暴露处理（Exposure）：C代表笼养蚊幼虫，NC代表暴露蚊幼虫； 3. 性别（Sex）：仅可对多数成虫蚊虫完成性别鉴定； 4. 化蛹时长（Tp）：即幼虫发育周期，单位为天； 5. 成虫寿命（Longevity）：成虫蚊虫从羽化至死亡的存活时长，单位为天； 6. 捕食者总密度（Density）：中型围隔内捕食者的总个体数； 7. 黾蝽属（Aquarius）数量：中型围隔内Aquarius的个体数量； 8. 甲虫类捕食者数量（Beetle）：中型围隔内Agabus（龙虱属）与Tropisternus（筒形水龟甲属）甲虫的总个体数； 9. 仰泳蝽属（Notonecta）数量：中型围隔内Notonecta的个体数量； 10. 蜓属（Aeshna）存在情况：群落中是否存在Aeshna？捕食者处理组填写“是”或“否”，无捕食者（或无Aeshna，类推）的对照组填写“对照（Control）”； 11. 香农-威纳均匀度指数（Shannon's H）：捕食者群落均匀度的Shannon's H计算值，对照组统一赋值为99，以方便筛选仅包含捕食者的处理组； 12. 性别标准化成虫寿命（Cslong）：经性别标准化处理的成虫寿命，计算方法详见Meadows等人的补充材料； 13. 成虫翅长（Winglength）：成虫蚊虫的翅长，单位为毫米（mm）
