Biology 2050 - Ecology Lab 2 (Grasslands - Dataset 2)

Data Collection Method: The transect tape was extended in a straight line across the grasslands for a distance of 91.5ft. Starting from the beginning of the tape purple flowering plants (Aster species) within 1m on either side of the transect tape were analyzed as the target plant species. The information collected (number of leaves, number of flowers, height, crowdedness, distance from transect tape) from observing these plants were recorded in a data table on a notepad. The height of the plant was measured using a transect tape, from the ground to the tip of the tallest flower. The number of leaves and flowers were approximated. The crowdedness around each plants was based on a 0-3 scale, 3 being the most crowded surroundings. The experiment was conducted to observe the abundance and density of the target species (Aster) in the grasslands. Target Species: Tall purple flowering plants (Aster Species) – easily identifiable among the various plants in the grasslands. Data Collection Date: September 26, 2014 Data Collection Location: The grasslands near York University were very abundant in various species of plants and insects (ex. Bees, mosquitoes, flowers, weeds, tall leafy plants). The area was dry and the temperature was about 22˚C. Data Collected with: Lilach Dahoah-Halevi and Cait Carew

数据采集方法：将样带绳（transect tape）沿直线横穿草原，布设长度为91.5英尺。以样带绳起点为起始点，对样带绳两侧各1米范围内的紫色开花植物——紫菀属（Aster）物种——作为目标植物开展分析。通过观测记录获取该类植物的相关信息（叶片数量、花朵数量、植株高度、拥挤度、与样带绳的距离），并记录至记事本的数据表格中。植株高度采用样带绳测量，测量范围为从地面至最高花朵的顶端；叶片与花朵数量采用估算方式记录；单株植物周边的拥挤度采用0-3级评分标准，3级代表周边环境最为拥挤。本次实验旨在观测草原中目标物种（紫菀属）的丰度与密度。
目标物种：高大紫色开花植物——紫菀属（Aster）物种，在草原各类植物中易于识别。
数据采集日期：2014年9月26日
数据采集地点：约克大学（York University）附近的草原，该区域内各类植物与昆虫（如蜜蜂、蚊子、花卉、杂草、高大阔叶植物）种类丰富，场地干燥，环境温度约为22℃。
