In which site do you expect greater biodiversity?
I expect greater biodiversity in the shaded area.
Sampling Plan:
Sample Method:
Transect; Shaded area
Sample Size:
(Transect (measurement))
= number of organisms in SG (rush family) = US & SS (Juncus Effusus)
(40) =
Individuals
Sample Method:
Transect; Unshaded area
Sample Size:
(Transect (measurement))
= number of organisms in SG (rush family) = US & SS (Juncus Effusus)
(40) =
Individuals
Data Collected:
US: When I see an US I will write it down either by name or nickname (description).

H = - (pa x ln pa + pb ln pb)
H = - (0.5 x In 0.5 + 0.5 In 0.5) = 0.693
pa = number of SS / total number
E = H/ln (S)
E = 0.693/ln(2) = 0.999 = 1
Shaded Area:
Pa = 20 / 40 = 0.5
Pb = 20 / 40 = 0.5
H = 0.693
E = 0.999 = 1
Unshaded Area:
Pa = 20 / 40 = 0.5
Pb = 20 / 40 =0.5
H = 0.693
E = 0.999 = 1
Summary:
Sampling Plan Summary:
For the experiment, my sampling method was the transect line. With the shaded area I started
from one palm tree to the other and that was about 10 meters long. With the unshaded area I
started from a bridge that you can kind of see in the picture I provided and stopped at the next
palm tree I saw and that was 10 meters long as well. I only did one transect line for each study
site (shaded/unshaded) equalling two. When I saw an unidentified species, I picked it and
added it to the collection bags I carried with me to collect my data and then I wrote it down when
I got home. For each transect line, I computed 20 single species (Juncus Effusus) and 20
unidentified species (Luzula).
Data Summary:
Both study sites had the same species richness, heterogeneity, and evenness.

When I first picked the plants they looked healthier but I put them outside because I didn’t want
them in my house and now they look scorched and unhealthy. I just wanted to note that.

What do we know about how your factor of interest affects biodiversity?
In an article I found, they stated that, “
Shading enhances plant species richness and diversity
most likely by
reducing drought stress”
(
Van der Kolk, HJ., Van den Berg, P., Korthals, G. et al.,
2020).

Final Paragraphs:
The biodiversity between my study sites were similar. They were similar because the results for
the S, E, and H were the same within my study sites (shaded/unshaded). In my prediction I
stated that I expect greater biodiversity in the shaded area. My results did not match my
prediction because my results are saying that biodiversity is the same in the shaded area and in
the unshaded area. According to my hypothesis, If vegetation thrives more in shade, then the
height of vegetation will be greater in shaded areas than in unshaded areas. The results would
neither support or negate my hypothesis because my results don’t involve plant height so I can’t
determine if the plant height is taller in shaded or unshaded areas. My results only involve the
species richness, heterogeneity, and evenness because that’s what I calculated.
