Insect Data from Grassland and Woodland Quadrat Samples

Data was collected using ten quadrat samples taken in both a grassland and woodland area in Toronto Ontario. The quadrants were used to observe species identity, number of insects in each species, total number of species, and the total number of insects. The data included insects in the quadrat ground area and insects flying within a meter above the quadrat. This data was collected by P Chow, N Gajendran, C Lau, and T Sequeira who all had designated roles in the data collection process. N Gajendran took five steps in any direction in attempt to keep quadrant sampling relatively random. N Gajendran identified a species while P Chow counted the number of insects in the quadrat of that species. T Sequeira identified flying species flying within a meter above the quadrat while C Lau counted the number of insects of that species. Data was recordedand number of insects of each species were added to record total number of insects within quadrat area.

本数据集的采集工作覆盖加拿大安大略省多伦多市的草原与林地两类生境，共设置10个样方(quadrat)样本。本次采样以样方为观测单元，记录内容包括物种鉴定结果、各物种种群的昆虫个体数、样方内物种总数以及昆虫总个体数。本次采集的数据涵盖样方地面区域内的陆生昆虫，以及样方上方1米范围内的飞行昆虫。本数据集由P Chow、N Gajendran、C Lau与T Sequeira四人共同完成采集，四人在流程中均承担了明确分工：N Gajendran通过向任意方向行走5步的方式，尽可能保障样方抽样的随机性；N Gajendran负责完成物种鉴定，P Chow则同步统计该样方内对应物种的昆虫个体数量；T Sequeira负责鉴定样方上方1米范围内的飞行昆虫物种，C Lau则统计该类飞行昆虫的个体数量。采集过程中，工作人员会逐一记录各物种的昆虫个体数，最终累加得到该样方区域内的昆虫总个体数。
