Week 4 lab - Field sampling training with animals Dataset 1

1 m by 1 m quadrats were randomly placed to sample insect population at the York University grasslands north of Pond Rd. All living individuals were sampled and number of snails was also included in the data. The total number of individuals was a tally of all the individual insects and snails found within the quadrat. The number of different taxonomic groups was specified using morphological differences visible to the naked eye. The number of individuals of each species of insect and snails was included to provide information as to the distribution of each species within the quadrat. 10 replicates were performed and placed randomly to prevent bias from genetic drift.在庞德路北侧的约克大学校园草地中，随机布设1米×1米样方（quadrat）以开展昆虫种群采样工作。本次采样覆盖所有存活个体，数据中亦纳入蜗牛的数量统计。样方内总个体数为该样方中发现的所有昆虫与蜗牛个体的计数总和。不同分类群的数量通过肉眼可见的形态差异进行界定。同时统计各昆虫与蜗牛物种的个体数量，以反映各物种在样方内的分布情况。本次实验共设置10组重复样方，且均随机布设，以规避遗传漂变所引发的采样偏差。
