Danby Woodlot Insect Diversity and Abundance

Experiment was conducted on Tuesday September 29th, 2015, at 3:00, at the Danby Grasslot in York University to observe the insect diversity and abundance in the area. A transect was laid out for 50 feet across the grasslot, insects were obtained by sweeping with a net for approximatly 2 minutes and 30 seconds over the 50 feet (Approxiamtly 2 sweeps every half foot.) At the end of the sweep Insects were taken out of the net and recorded. The sweeping was repeated 10 times, each new transect line was at a 45° angle from the end of the previous line, creating an overall zigzag pattern. This experiment was done in the rain, creating a bias for certain insects such as the Grove Snail (<em>Cepaea nemoralis</em>.) Experiment was conducted by Markian Plawiuk, with help from Bonnie Duong and Nicole Gallagher.

2015年9月29日星期二3时，本实验于约克大学（York University）丹比草地（Danby Grasslot）开展，旨在调查该区域的昆虫多样性与种群丰度。研究人员沿该草地布设一条长50英尺的样带，在该样带范围内以扫网采样约2分30秒，约每半英尺进行2次扫网动作。每次扫网结束后，将网内捕获的昆虫取出并记录。上述扫网流程共重复10次，每条后续布设的样带均与前一样带的末端呈45°夹角，整体形成之字形采样路径。本次实验在降雨天气下开展，该环境条件会对部分类群造成采样偏差，例如树林蜗牛（Grove Snail，*Cepaea nemoralis*）。本实验由Markian Plawiuk主持，Bonnie Duong与Nicole Gallagher协助完成。
