Insects in woodlot and grasslands found using a quadrat

Our Data was collected on September 29, 2015 at approximatley 3:20pm-3:50pm at the York University Keele campus. It was about 18 degrees C on this afternoon with minimal to no sunlight from cloud coverage, constant precipitation and wind the entire time working there. In the above table, the abbreviation "g" was used for grasslands and "w" was used for woodlot. Myself as well as my group Katie, Adam, Ashley and Ava worked together to collect the above data. We hypothesized that because of the weather conditions we would not be able to find many insects or diversity of insects with mainly finding ants or worms. The experiment comprised of taking the quadrant and placing it in 10 random locations throughout the woodlot and 10 in the grasslands. None of the locations were particularly close to eachother and we tried to pick locations that were different from one another, for example one in the grasslands consisted of short plants and some small flowers while other locations were in the tall grass with bigger plants. Once quadrants were placed, we then would look throughout the entire area of the quadrant and recored the number of insects found, as well as their taxonomic units. This technique was done both in the grasslands and in the woodlot and the total area observed was about 100 by 100 feet. As predicted, there was not a large count of insects found, but there was more variety in insects then originally thought. Many ants were spotted as well as a couple of snails, crickets, spiders, flies, pill bugs,small moths and one worm and one large praying mantus. A total of 72 insects were found between both the Danby woodlot and grasslands.本数据集采集于2015年9月29日约15:20至15:50，地点为约克大学基尔校区（York University Keele campus）。当日下午气温约18摄氏度，受云层覆盖影响几乎无日照，调查全程伴随持续降水与大风。在前述表格中，缩写“g”代表草地（grasslands），“w”代表林地（woodlot）。本人与组员Katie、Adam、Ashley、Ava共同完成了本次数据采集工作。我们提出假设：受当日天气条件影响，难以发现大量昆虫或丰富的昆虫类群，大概率仅能采集到蚂蚁或蚯蚓。本实验采用样方（quadrant）调查法：将样方随机放置在林地10个点位与草地10个点位，所有点位彼此间距较远，且尽量选取存在差异的生境——例如一处草地样点生长着低矮植物与小型花卉，其余样点则为高草与大型植株。完成样方放置后，我们对样方覆盖的全部区域进行排查，记录所发现昆虫的数量及其分类单元（taxonomic units）。该调查方法同时应用于草地与林地，总调查面积约为100×100平方英尺。正如预期，本次调查未发现大量昆虫，但昆虫类群的多样性超出了最初的预判。共记录到蚂蚁、多只蜗牛、蟋蟀、蜘蛛、苍蝇、潮虫（pill bugs）、小型蛾类、1只蚯蚓以及1只大型螳螂（praying mantus）。本次在丹比林地（Danby woodlot）与草地中共计发现72只昆虫。
