BIOL2050 Lab2-Grassland dataset 2

The purpose of this experiment was to collect data based on transect technique and to observe the abundance of Purple Aster from the grassland around Danby Woods where located at south of Chimneystack Rd. and west of Keele St. of York University Keele campus on September 26, 2014. The temperature was about 25 degrees Celsius with a clear blue sky. Purple Aster is easily identified from other species in the grassland, so it reduced the possibility of choosing wrong species. We randomly chose a Purple Aster and lay the transect tape down. The total 50 samples of Purple Aster along the transect tape were collected and recorded the distance on transect. The height of the plant, number of leaves, number of flowers and level of crowding were also recorded in the dataset. The experiment was collaborated with Naz Naji, Kristine Gulli, and Winnie Zhao.本实验旨在基于样带技术（transect technique）采集数据，于2014年9月26日，在约克大学基尔校区（York University Keele campus）烟囱路（Chimneystack Rd.）南侧、基尔街（Keele St.）西侧的丹比树林（Danby Woods）周边草地中，开展紫菀（Purple Aster）种群丰度的观测研究。当日气温约25摄氏度，天空晴朗湛蓝。紫菀与该草地中的其他物种易于区分，因此降低了物种鉴定失误的概率。我们随机选取一株紫菀并布设样带卷尺，沿该样带共采集50个紫菀样本，记录各样本在样带上的位置距离。本数据集同时记录了该植物的株高、叶片数、花朵数以及种群拥挤程度。本实验由Naz Naji、Kristine Gulli与Winnie Zhao协作完成。
