资源简介:
Data was collected to determine the population density of milkweed over a certain amount of area. Two 25 metre transects were placed randomly in the grasslands. The first 20 easily identifiable milkweed plants were studied that layed along the transect. The distance from the beginning of the transect to the middle of the plant was recorded in feet later converted to inches. Using a second transect, the height of the plant was recorded in inches. Researchers then observed and counted how many leaves were attached to the plant as well as the number of alive flowers. The level of crowding around the plant was determined by the researchers based on a 0-3 scale where 0 was determined as no surrounding plants, 1 was determined as minimal crowding having some plants surrounding it, 2 was determined as medium crowding having multiple plants around the plant and 3 was determined as heavily crowded with many plants surrounding the individual species. Data was collected at Danby grasslands at York University on September 23rd, 2015 around 3:30pm. The weather was around 25°C with clear skies on a sunny day. Very minimal shade cover. The transects were placed randomly where milkweed was visible. The members of group 4 are Kristine Del Rosario, Kate Britanico, Nassar Khan, Michael Angelini.
