Description of column headers:Habitat: it refers to a natural environment where certain animals or plants can be found. This study was conducted in two habitats: woodlot and grassland on Keele Campus of York University in order to get some data about insects.Grassland: in this study, it refers to a small open area covered mostly with grasses near York Boulevard at Keele campus in York University.Woodlot: in this study, it refers to a small area dominated mostly with trees near York Boulevard at Keele campus in York University.Sweep Nets Trials: it refers to the number of sweep net experiment that was done. This study was done in grassland and woodlot, and in each habitat, there were 10 sweep nets trials.Number of Organisms: refer to the total number of organisms (insects in this study) that would get caught by sweep net in each trail.RTUs: refer to recognizable taxonomic units. Here, it simply means the number of species in each trail.Hypothesis and predictions:Hypothesis: The number and type of insect species in grasslands are more than woodlots.Predictions: 1) There would be more insects caught in the sweep nets per trial in the grasslands compared to woodlots.2) There would be more variety of species caught in the sweep nets per trial in grasslands compared to woodlots.3) There would be more insect pollinators in grasslands due to having more variety of plants.Type of Data: Habitats, the number of organisms and RTUs are all categorical. Habitat was categorized into two groups of grassland and woodlot. The number of organisms and RTUs are discrete numbers as well.Time of experiment: between 15:22 and 15:55Date of experiment: September 27, 2016Location of experiment: grassland and woodlot near York Boulevard at Keele campus, York UniversityWeather: 20 °C Method: The experiment took place on Tuesday, September 27, 2016, from approximately 15:22 to 15:55. In this study, by using a sweep net, it was tried to find the number and type of insect species in the grassland and woodlot near York Boulevard at Keele campus, York University. In both grassland and woodlot, the sampler walked in a random straight line about 25 meters moving the sweep net randomly and constantly to catch insects for each trial. At the end of each trial, the number of organisms and number of species were recorded.列标题说明： 生境（Habitat）：指特定动植物赖以生存的自然环境。本研究于约克大学基尔校区的两种生境中开展，即林地块与草地，以获取昆虫相关研究数据。 草地（Grassland）：本研究中特指约克大学基尔校区约克大道附近一片以草本植被为主的小型开阔区域。 林地块（Woodlot）：本研究中特指约克大学基尔校区约克大道附近一片以乔木植被为主的小型区域。 扫网试验（Sweep Nets Trials）：指开展的扫网实验次数。本研究在草地与林地块两种生境中各开展了10次扫网试验。 生物个体数（Number of Organisms）：指单次扫网试验中，扫网捕获的总生物个体数（本研究中特指昆虫）。 可识别分类单元（RTUs，Recognizable Taxonomic Units）：本研究中特指单次试验中捕获的昆虫物种数量。 研究假设与预测： 研究假设：草地中的昆虫物种数量与种类丰富度均高于林地块。 预测内容：1）单次扫网试验中，草地捕获的昆虫个体数将多于林地块；2）单次扫网试验中，草地捕获的昆虫物种种类将多于林地块；3）由于草地拥有更多样的植物类群，其昆虫传粉者的数量也将更多。 数据类型：生境、生物个体数与可识别分类单元均为分类变量。其中生境被划分为草地与林地块两个类别；生物个体数与可识别分类单元均为离散数值变量。 试验时间：15:22至15:55之间 试验日期：2016年9月27日 试验地点：约克大学基尔校区约克大道附近的草地与林地块 天气情况：20℃ 试验方法：本试验于2016年9月27日周二，大致在15:22至15:55期间开展。研究人员采用扫网法，对约克大学基尔校区约克大道附近的草地与林地块内的昆虫物种数量与种类进行调查。在两种生境中，研究人员均沿随机直线行走约25米，过程中持续随机挥动扫网以捕获昆虫；每完成一次试验后，记录本次试验捕获的生物个体数与物种数。
