Sweep net data from Stong Pond gassland

This study was conducted to observe the diversity of insects in the York University Stong Pond grasslands. To do this, a transect was laid out in ten randomly seleted places. A sweep net was used to sweep 50 centimetres on either side of the transect (belt transect) for eight metres for approximately one minute. At the end of each sweep, the organisms caught in the net were counted, along with the number of recognizable taxonomic units (RTUs), and then set free in roughly the same location they were caught. Starting locations for each replicate were randomized by turning 30 degrees to the right and taking 10 steps from the starting location of the previous transect's starting point. The study was done on September 28th, 2015. It was approximately 20 degrees celsius and there was a light breeze. Earlier in the day there had been rain and the sky was still overcast.

本研究旨在调查约克大学斯壮池塘草原的昆虫多样性。为此，研究人员在10个随机选取的地点布设了样带。使用扫网（sweep net）沿带状样带（belt transect）两侧各50厘米、总长8米的范围进行扫捕，单次扫捕时长约1分钟。每次扫捕结束后，统计网内捕获的生物个体数与可识别分类单元（recognizable taxonomic units, RTUs）数量，随后将捕获生物在原捕获地点附近放生。每个重复样带的起始位置通过如下方式随机确定：以上一个样带的起始点为参照，向右旋转30度后行进10步，以此确定本次样带的起始位置。本研究于2015年9月28日开展，当日气温约为20摄氏度，伴有微风。当日早些时候曾有降雨，天空仍保持阴天状态。
