Affect of human traffic and urbanization on insect abundance and traffic

This experiment is looking at abundance and diversity of insects and if that is affected by human activity in high and low traffic areas at York University. High traffic areas are defined as areas that no ground is showing ie the ground is covered by concrete and more than 5 people walk by going in one direction in 10 seconds. The low traffic areas are deemed by having no person walk through the area during 1 minute and having nature ie trees, shrubs, grass and no concrete on the ground.Three locations were visited each week for two weeks, October 14th and 21st. The three locations of low traffic are are the woodlot behind Osgood Law School, the Danby woods/woodlot and the woods/woodlot surrounding Stong Pond. The high traffic areas in front of Lassonde School of Engineering, in front of Vari Hall/the bus loop and in front of Stong college. The 4 group members spilt into teams of 2 for time conservation since some of the locations were on opposite sides of York Univeristy. At each location,10 pan traps were placed and collected at 1.5 hours. The pan traps were undisturbed for the full 1.5 hours. The locations of the pan traps were randomly selected and placed 1 meter apart. The pan traps were placed within the brushes at each location to unsure the highest number of bugs caught and for location of high traffic so no person would kick or knock over the trap. The insect abundance and diveristy using RTU's were recorded. We are observing how much of an impact has human activity affected biotic-biotic interactions.

本实验旨在探究约克大学（York University）高、低人流量区域内昆虫的丰度与多样性，以及人类活动对其产生的影响。高人流量区域指无裸露地面（地面被混凝土完全覆盖）且单方向10秒内有5人及以上经过的区域；低人流量区域则为1分钟内无人员经过、存在自然植被（树木、灌木、草地）且地面无混凝土覆盖的区域。
实验周期为两周，分别为10月14日与21日，每周需走访三个采样点位。其中低人流量采样点位包括奥斯古德法学院（Osgood Law School）后方林地、丹比林地以及斯通池塘（Stong Pond）周边林地；高人流量采样点位包括拉松德工程学院（Lassonde School of Engineering）前方、瓦里大厅/公交环线前方以及斯通学院（Stong College）前方。
4名实验组员分为两组，每组2人开展采样工作，以节省时间——部分点位位于约克大学校园的对立两侧。
在每个采样点位随机布设10个色盘诱捕器（pan traps），诱捕器间距为1米，且设置于灌丛中以最大化捕获昆虫的数量；在高人流量区域布设时，该布置方式可避免过往人员踢碰或碰倒诱捕器。色盘诱捕器需在原地静置完整1.5小时后回收，期间保持未受任何干扰。
基于可识别分类单元（RTU）记录昆虫的丰度与多样性，本研究旨在明确人类活动对生物间相互作用的影响程度。
