Impact of predator diversity treatments on aphid prey density

Predator density and diversity were manipulated in a field cage experiment.

The data uploaded is the mean numbers and standard deviation of aphids (R. padi) at predator introduction and at the end of experiment 12 days later.

we had:
- Three low diversity treatments: carabid P. melanarius, ladybird larvae (C. septempunctata), lacewing larvae (C. carnea)
- A high diversity treatment using a subsitutive design

本研究通过田间笼式实验操控了捕食者的种群密度与物种多样性。

本次上传的数据集记录了捕食者接入时，以及12天后实验结束时麦二叉蚜（R. padi）的平均种群数量与标准差。

本实验设置如下处理组：
- 三类低多样性单种处理组：步甲（P. melanarius）、七星瓢虫（C. septempunctata）幼虫以及大草蛉（C. carnea）幼虫
- 采用替换设计的高多样性混合处理组
