Woodlot and Grassland Pan Traps in Danby Woods

The data was collected on 30 September, 2014, at around 4:00 PM. The location was the Danby Woods at the York University Campus (Keele location.) The weather at the time was roughly 18°C. Using the Beaufort Scale, the wind was determined to be calm throughout the experiment.(Source: https://weatherspark.com/averages/28179/9/30/Toronto-Ontario-Canada) For both the Grassland and Woodlot, 10 pans of varying colors were arranged in different layouts (based on color) in a straight line, with 1 feet between them (transect.) The layouts can be seen above. These pans were filled with soapy water to about half way of the pan. The soap allowed the water tension to be reduced, which allowed for insects to drown, as opposed to escape, due to the higher surface tension of water. Pans were allowed to sit for 1 hour, after which they were surveyed for their contents. Data regarding the number of species, the different species of insects and total number of insects were collected.

本数据集采集于2014年9月30日约下午4时。采集地点为约克大学校园基尔校区（York University Campus (Keele location)）的丹比林地（Danby Woods）。当日气温约为18℃，依据蒲福风力等级表（Beaufort Scale）判定，整个实验期间风力均为静风。数据来源：https://weatherspark.com/averages/28179/9/30/Toronto-Ontario-Canada

针对草原与林地生境，我们依据颜色差异设计了不同布设方案，将10个不同颜色的诱集盘沿直线布设为样带（transect），盘间距为1英尺。该布设方案详见前文图示。诱集盘内注入约半盘容量的肥皂水：肥皂水可降低水的表面张力，而纯水因表面张力较高，可支撑昆虫在水面站立并逃脱；注入肥皂水后，昆虫无法借助水面张力维持站立，进而溺亡。

诱集盘静置1小时后，研究人员对其内部采集物开展调查统计，最终获取了物种数量、昆虫种类组成以及昆虫总个体数相关数据。
