Answer 1

Diversity Index Lab

The measure of the biodiversity (variety of species in a specific area) of organisms in a given area is known as the diversity index. Your diversity index values will be between 0 and 1. A value of 0 would indicate no diversity and a value of 1 would be very diverse. Usually, anything above 0.5 is a relatively diverse population. In this lab you will be using candy to represent 2 different habitats. Each color of candy represents a different plant in that habitat.

Materials: paper, fruit candies (like Skittles), chocolate candies (like M&M’s), 2 bowls or plastic containers

Procedures:
1. Put the fruit candies in one container and the chocolate candies in a different container.
2. Assign each color a different letter to create your key and write this information down. For example: chocolate orange is O, fruit orange is o.
3. Without looking, randomly choose 9 candies from each container 1 at a time.
4. Using your letter key, record each candy as you remove it from the container. You will write the results in a single line.
For example: 0RGGYYBBR
The above would be represent the following picks out of the chocolate container: orange, red, green, green, yellow, yellow, brown, brown, red
5. You will need to repeat step 4 two more times for each type of candy so that you have a total of 3 lines from each container of candies. You will put the candies back into the container after you have picked 9 so that they are in the container for the next trial.
For example:
Chocolate Candies: Fruit Candies:
Trial 1: ORGGYYBBR Trial 1: yorrgbooy
Trial 2: RGYYBROOR Trial 2: byyrrgoog
Trial 3: YGBBRYYRR Trail 3: gryybyrro

6. Now you will need to determine the number of runs for each line. A run is a group of letters in a row that are the same.
Example:
Trial 1: ORGGYYBBR this trial would have 6 runs---O is 1, R is 1, GG is 1, YY is 1, BB is 1, R is 1
Add those together for a total of 6 runs in that trial.

7. Determine the number of runs for each trial.
8. Now you will use the number of runs to determine the diversity index of your “plants” (candies). To determine the diversity index you will divide the number of runs in a trial by the number of “plants” (candies) chosen. The number of “plants” (candies) for every trial is 9 (this is how many times you drew a piece of candy).
Example for trial 1 of the chocolate candies:
# of runs = 6 # of “plants” (candies) =9
So, my diversity index for this trial is 6/9=0.67

9. Determine and record the diversity index for each of your trials for the chocolate and fruit candies.

You will need to turn in the following calculations and answers for your portfolio grade. Submit your portfolio through the dropbox at the end of the lesson. (total 16 pts):
1. Diversity index number for each trial (1 point each for a total of 6 points)
2. How did the diversity index values vary from the chocolate candies and the fruit candies? (1 point)
3. Which habitat is the most diverse? Explain your answer. (3 points)
4. Why are populations that are more diverse usually more stable? (3 points)
5. Why would a diverse population be more resistant to disease, predation, and invasion? (3
