Wooly Worms Conclusion
a. Degrees of freedom: 6
c. Chi-square value: 40.06
d. They do not indicate this because since we had a high chi-squared value, the selection of worms was not random.
e. Positive selection pressure: Shrek, Burt, Stringbean, Olive Garden
Negative selection pressure: Stripey, Eyelash, Shaggy
f. These results indicate that those with negative selection pressure will get picked off quickly, and those with positive selection pressure will survive longer.
g. Predatory birds will most likely be attracted to prey of brighter colors because they can be spotted more easily than other worms. Therefore, if a worms is a bright color or has distinguishable characteristics, they will most likely be a greater target to birds of prey.
h. The population would change in that the worms with negative selection pressure would be possibly wiped out and the community of worms would be reduced to only worms with positive selection pressure.

Post Lab Questions
1. Identify the parking lot that was the most diverse. Based on your observations during the lab, explain why your
prediction in question #1 of the prelab was supported or not supported.
2. List the single most abundant species in each set of data, and write a plausible explanation to explain why these are
the most abundant species.
3. Determine the maximum and minimum values for the Shannon Diversity Index in the parking lot you surveyed.
4. If you conducted this lab in a shopping mall parking lot, predict whether the Shannon Diversity Index would be high or
low, and how it would compare to the school parking lots.
5. If you conducted this lab at a new car dealership, predict whether the Shannon Diversity Index would be high or low,
and how it would compare to the school parking lots.

Population Pyramid
The population is increasing because of the large amount of young college students.
The population is increasing because of the abundant amount of 25-29 year olds.
The population is stable because of the large amount of middle aged people living there.
The population is stable because the amount of people coming and leaving is roughly the same.
The population is increasing because of the enormous amount of 60 and under crowd.
The population is expanding slowly because it is gradually expanding its size.
The population is stable because the amount of people coming and leaving Turlock is relatively balanced.
