WK6&WK7: Field experiment datasets

This field experiment was conducted to determine the relation between canopy cover, and number of insects present in that area which took place on York University's Osgoode and Boyer woodlots on October 15 and 22, 2015. There were three specific areas of concern which consisted of low, medium, and high canopy coverage. Each particular area contained 15 pan traps in ratio of 5:5:5 red, yellow, and white respectively that were positioned 1 metre apart while being within the selected canopy area. Each bowl contained a mixture of soapy water that remained in the selected canopy area for 2 hours before being collected at the end to identify and record the insect species. This was done for two datasets, one per week. The canopy level of each area was determined by a physical observation, and using both hands to create a square to estimate the percetange of coverage visible. The percentages were categorized into three levels of coverage, low(0%-35%), medium(35%-65%), and high(65%-100%). From dataset 1, the number of insects recorded was proportional to canopy level from low to high cover, while in dataset 2, the number of insects increased when going from low to medium canopy coverage, but number of insects were significantly reduced with high canopy coverage. Weather conditions had an indirect relationship to this experiment as both days were cloudy, and had some light rain which may have triggered different responses depending on the particular insect species.

本野外实验于2015年10月15日及22日在约克大学（York University）的奥斯古德林地（Osgoode Woodlots）与博耶林地（Boyer Woodlots）开展，旨在探究林冠覆盖度与该区域内昆虫数量之间的关联。
本次实验共设置3个核心研究区域，分别对应低、中、高三种林冠覆盖度等级。每个区域内布设15个盘式诱捕器（pan traps），其中红色、黄色、白色诱捕器的数量比例为5:5:5；诱捕器间距为1米，且均位于选定的林冠区域内。每个诱捕器内均盛放肥皂水混合液，将诱捕器置于选定林冠区域内2小时后回收，用于后续昆虫物种的鉴定与记录工作。本次实验共生成两组数据集，每周采集一组。
各区域的林冠覆盖等级通过人工观测确定：以双手搭建正方形框架估算可见林冠覆盖率，并将覆盖率划分为三个等级：低覆盖（0%~35%）、中覆盖（35%~65%）、高覆盖（65%~100%）。
第一组数据集显示，记录的昆虫数量随林冠覆盖度从低到高呈正比递增；第二组数据集则显示，昆虫数量在林冠覆盖度从低升至中时有所增加，但当覆盖度达到高等级时，昆虫数量显著减少。
天气条件对本实验存在间接影响：两日均为多云天气且伴有小雨，这可能因昆虫物种的差异而引发各异的行为响应。
