Soil Depth and Canopy Does Not Cause Clumped Dispersion in Bidens Pilosa
I only need the discussion part of this paper done
After arriving at the pine rockland habitat, an initial visual impression was gathered to determine the density and dispersion patterns of noticeable plant species. A large 15×15 meter grid was then set up. A random number generator was used to generate 10 random numbers within the range of 0-15 to be used as x-coordinates. The random number generator was then used to do the same to generate 10 numbers to be used as y-coordinates. The points were then located on the 15×15 meter grid. At each point, the number of individuals from the Bidens alba species were counted. The soil depth in centimeters was also measured at each point by driving a stake as far into the ground as possible. within a radius around the point. The distance from each point to the nearest tree was also measured.
Results
In this survey, the counted an average of 4.6 B. pilosa per plot with a variance of 15.37778. The dispersion pattern based on the ratio of variance/mean was 3.342995. (Figure 1).
It is evident from the dendrograms (Figure 1), that quadrants are most similar in terms of their distance from a tree, followed by soil depth, then their abundance (their distance from one another), and finally geography. Abundance had the greatest variance between quadrants.
