<b>Data Column Headers and Descriptions:</b> <b>Habitat: </b>A grassland is defined as an open area at least 250m by 250m in size with few trees; forest is a woodlot on campus <b>Sweep net replicate: </b>This refers to the trial that was conducted. 10 separate sweep net trials were conducted in the grassland habitat and 10 separate sweep net trials were conducted in the woodlot habitat. <b>Number of Organisms: </b>The total number of insect found in the sweep nets after sweeping for 25 meters. <b>Number of Species:</b> The total number of recognizably different insect species in the sweep nets. <b>Additional Information:</b> <b>Hypothesis: </b>There will be a higher number of insects found in the grasslands than in the woodlots. <b>Prediction</b>: It is predicted that there will be a higher number of organisms observed in the sweep nets in the grasslands and a lower number of organisms observed in sweep nets in the woodlots. <b>Type of data collected: </b>The collected data was categorical. The data was grouped into the number of insects found in each sweep net replicate. <b>Time Data Was Collected: </b>Tuesday, September 27, 2016. 3:23-4:25 PM EST. <b>Location of Data</b>: Woodlot and grassland at York University, near York Boulevard. Latitude and longitude: 43.7775, -79.507. <b>Weather Conditions</b>: 20 degrees Celsius, cloudy, dry conditions. <b>Survey Method</b>: Sweep nets with a diameter of 32 cm and a depth of 73 cm were used in the experiment. 10 sweep net trials were conducted in the grassland habitat and 10 sweep net trials were conducted in the woodlot habitat. 25 meters was walked straight with the sweep net held in hand, moving through the air to catch any insects. Transect measuring tape was used to measure the distance walked. After the completion of the 25 meter walk, the number of organisms in the sweep nets was assessed and recorded, as well as the number of different recognizable species. <b></b>

<b>数据列标题与说明：</b><b>生境（Habitat）：</b> 草地被定义为面积不小于250米×250米、树木稀疏的开阔区域；森林（forest）即校园内的林地块（woodlot）。<b>扫网重复采样组（Sweep net replicate）：</b> 指代本次实验开展的独立采样试验。本研究在草地生境与林地块生境中各完成10组独立扫网采样试验。<b>生物个体总数（Number of Organisms）：</b> 指经25米扫网采样后，扫网内捕获的昆虫总数量。<b>昆虫物种总数（Number of Species）：</b> 指扫网内捕获的可辨识昆虫物种的总数量。<b>补充信息：</b><b>研究假设（Hypothesis）：</b> 草地生境中的昆虫数量将高于林地块生境。<b>预测结果（Prediction）：</b> 本研究预测，草地生境的扫网采样中观测到的生物个体数量更高，而林地块生境的扫网采样中观测到的生物个体数量更低。<b>数据类型（Type of data collected）：</b> 本次采集的数据为分类数据，按每组扫网重复采样组捕获的昆虫数量进行分组统计。<b>数据采集时间（Time Data Was Collected）：</b> 2016年9月27日，星期二，东部夏令时15:23至16:25。<b>数据采集地点（Location of Data）：</b> 约克大学（York University）校园内的林地块与草地，毗邻约克大道（York Boulevard）。经纬度坐标：43.7775, -79.507。<b>天气状况（Weather Conditions）：</b> 气温20摄氏度，多云，天气干燥。<b>采样方法（Survey Method）：</b> 本实验采用直径32厘米、深度73厘米的扫网开展采样。研究人员在草地生境与林地块生境中各开展10组扫网试验：手持扫网沿直线行走25米，同时在空中挥网以捕获沿途昆虫，采样过程中使用样带卷尺（transect measuring tape）测量行走距离。完成25米行走后，对扫网内的生物个体数量与可辨识物种数量进行计数并记录。
