week 5 - experiment design

We will use 12 of each coloured bowls to set out pantraps in the grasslands. We will set them with alternative colours repeating and try to cover as much area of the York u's grasslands as possible. The pantraps will be set out at the beginning of the lab (2:30 pm Monday Oct. 20th 2014) until the end of the lab period for 3 hours. At the 3 hours mark the pantraps will be surveyed for the trapped macroinvertebrates and data will be collected (possibly pictures will be taken for further identifying to species). If as a group it was decided that we needed more sets to run, we will accommodate another day to run the same experiment.我们将使用每种颜色各12个的彩色碗，布设浅盘诱捕器（pantraps）。布设过程中将采用交替配色的循环排布方式，尽可能覆盖约克大学（York University）草原区域的最大范围。本次布设工作将于2014年10月20日周一下午2:30启动，持续3小时至实验时段结束。布设完成3小时后，将对诱捕器内捕获的大型无脊椎动物开展调查并采集相关数据，同时可能拍摄照片以用于后续物种鉴定。若经团队集体商议，认为需增设更多实验组，则将改日重复开展本实验。
