Comparing Biodiversity
1. First, make a hypothesis about the diversity
of spiders in the (Habitats A & B). Without looking at the spider habitat
sheet... which habitat do you think will be more diverse in terms of spider?
Explain your reasoning.
Habitat A will have more diversity than Habitat B because it has the most habitat/niches.

2. How many species of spiders did you find in…
Habitat A: 4 Habitat B:2
3. What was the AVERAGE number of spiders you found per
quadrat?
Habitat A:6.3 Habitat B:5.3
4. Twelve quadrats can fit in this area. How many spiders do you
estimate are found in the whole area?
Habitat A:72 Habitat B:60
5. Look at the bottom sheet of paper with the spiders on it. How
many spiders are there in…
Habitat A: 19 Habitat B:16
6. Was your estimate close to the actual number of spiders in
the area?
It was close but not close to perfect.
7. Why might there be a difference between your sample estimate and the actual number?
There might be a mistake while counting the spiders.

8. Based on the proportions you just calculated (Table 4), do
you think the species are evenly distributed within the habitats?
Habitat A: in habitat A species 'c' and 'D' are almost evenly distributed while specie 'B' is a bit less and specie 'A' is far less than the other species
Habitat B: Species 'C' and 'D' are evenly distributed but the whole species aren't evenly distributed.
9. Is this what you think it would be like in nature? Why?
yes, in nature species aren't going to be evenly distributed because they have different limiting factors and survival rates.
10. Was your original hypothesis supported by the data you
collected today? Why or why not?
Yes, the hypothesis Habitat A has more diverse species than Habitat B is supported because the more species you have the more diversity it'll experience.
11. What did you learn about doing a biodiversity quadrat study?
When doing a biodiversity quadrant study we should be careful on the counts we are making because if we get the counting wrong it'll mess up our estimate population guess we're making.
