Sampling Wild Carrots in the Danby Grassland using Transects

The purpose of this experiment is to determine if the traits of the plant, Wild Carrot or Daucus carota, has any effect on how the plants get dispersed. The experiment was conducted in the Danby Grassland at York University near Keele Street. A 30 m transect tape was randomly placed in the open area with shorter grasses (about 10 cm tall). A total of 20 individual wild carrots were sampled along the transect tape. The distance on transect, height, number of leaves, number of flowers, and level of crowding of each wild carrot were observed. All data were collected through visual observation, with the aid of a second transect tape when measuring the height. Data was collected during a sunny and hot day on September 23, 2015, from 3:30 pm to 4:00 pm, with a very slight breeze. Data was collected by Mandy Huynh, Dylan Stoll, Mariam Nnanna, and Jordan Deosamy. Dylan and Jordan were in charged of reading the distance on the transect tape and the height of each wild carrot. Miriam determined the level of crowding around each wild carrot within a range of 50 cm. Finally, I was in charge of counting the number of leaves and flowers, and recording all the data.

本实验旨在探究野生胡萝卜（别称Wild Carrot，学名*Daucus carota*）的各项性状对其传播方式是否存在影响。实验在毗邻基尔街（Keele Street）的约克大学（York University）丹比草原（Danby Grassland）场地开展：在高度约10厘米的低矮开阔草地中随机布设一条30米的样带卷尺，沿该样带共采集20株野生胡萝卜个体，记录每株野生胡萝卜的沿样带距离、株高、叶片数、花朵数以及周边拥挤度。所有数据均通过目视观测获取，测量株高时需借助第二条样带卷尺辅助。数据采集工作于2015年9月23日晴热的一天进行，时段为下午3:30至4:00，当时仅有微弱微风。本次数据采集由Mandy Huynh、Dylan Stoll、Mariam Nnanna与Jordan Deosamy共同完成：其中Dylan与Jordan负责读取样带卷尺上的沿样带距离与单株野生胡萝卜的株高；Mariam负责测定每株野生胡萝卜周围50厘米范围内的拥挤度；本人则负责统计叶片与花朵数量，并记录全部实验数据。
