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 spider diversity. There are more diverse niches in habitat A
2. How many species of spiders did you find in...
Habitat A: 3
Habitat B: 2 3. What was the AVERAGE number of spiders you found per quadrat?
Habitat A: 16/3=5.33
Habitat B: 14/3= 466
4. Twelve quadrats can fit in this area. How many spiders do you estimate are found in the whole area?
Habitat A: 5.33*4=21.32
Habitat B: 4.66*4=18.64
5. Look at the bottom sheet of paper with the spiders on it. How many spiders are there in...
Habitat A: 22
Habitat B: 20
6. Was your estimate close to the actual number of spiders in the area?
Our estimate was close to the actual number
7. Why might there be a difference between your sample estimate and the actual number?
One of the quadrats might have cut off a spider. There may have been a counting mistake
8. Based on the proportions you just calculated (Table 4), do you think the species are evenly distributed within the habitats?
Habitat A: Species B and D are evenly distributed, but between all four species, it is not even
Habitat B: Species C and d are evenly distributed, but between all four species, it is not even
9. Is this what you think it would be like in nature? Why?
Yes. In nature every ecosystem has different niches within that on ecosystem
10. Was your original hypothesis supported by the data you collected today? Why or why not?
Our original hypothesis was supported by the data. Habitat A had more biodiversity
11. What did you learn about doing a biodiversity quadrat study?
Quadrat square is a method used to estimate biodiversity in a habitat
Habitat A will have more spider diversity. There are more diverse niches in habitat A
