Population Pyramids
Turlock's population is steady to slowly declining. I believe the steadiness is due to more jobs being available in the area but the declining is due to people moving away after retirement.
In Pismo Beach the population is mainly declining. I believe this is due to it being a small beach town that many elder people retire to.
In Tampa, Florida the population is pretty steady. I believe this is due to Tampa being a large town with many jobs available.
In Grapevine, Texas the population is stable to slowly declining. I believe this is due to the location of the town, it is outside of the large cities and is cheaper to live.
In Santa Barbara, CA the population is pretty steady. I believe this is due to the wonderful weather and great location. There is a peak around college aged people due to the college in Santa Barbara.
In Portland, OR the population is slowly declining to slowly expanding. I believe this is happening because Portland's location made it hard to settle down and start families in the past few years.
In Sonoma, CA the population is slowly declining. I believe this is due to the large number of people that retire to this small town.
Data Snapshots from Climate.gov
This photo shows the current drought situation in the United States. This shows that the drought has drastically reduced in the US and especially in California over the past few years.
This photo shows the average temperature in the United States in August of 2005 and 2017. They are both similar just the colors are a bit darker in 2017 which means the average temperature is a little higher now.
This photo shows the Sea Surface Temperature in August of 2017. I was surprised how warm the ocean is near Japan and Florida but it would help to explain all the hurricanes happening.
This shows the average precipitation in the United States in February of 2017. I was surprised by this data because it showed when California gets rain no other states really do.
In this picture it shows the probability of the temperatures being either higher or lower than normal. I was surprised by how much warmer it is supposed to be on the left side of the U.S. than normal.

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.
The more diverse parking lot was the student parking lot. I predicted the student parking lot would be the more diverse because students have a wide range of cars, parents can by cars for the students or student can buy their own cars, which creates a wide range.
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.
In the student parking lot the most abundant species was the Chevy with 21 cars and in the staff parking lot the most abundant species was Ford with 14. I believe these species were the most abundant because we live in the valley that is heavy with agriculture, so people use trucks.
3. Determine the maximum and minimum values for the Shannon Diversity Index in the parking lot you surveyed.
For the student parking lot the diversity maximum was 2.36. For the staff parking lot the diversity minimum was 2.34.
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.
In a shopping mall parking lot the Shannon Diversity Index would be higher because there is a larger pool of cars and all different types of people go to the mall.
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.
If we did this lab at a new car dealership the Shannon Diversity Index would be lower because there would mainly only be one or two types of cars there. Where as in the student parking lot there are all types of cars.

Wooly Worm Conclusion
a. The degrees of freedom is 6.
c. The chi-squared value is 79.23.
d. The results show that the worms picked up were not by chance. There was a probable reason why some were picked over others, colors.
e. The darker green and brown worms were subject to a positive selection pressure due to the colors blending into the ground.
While the brighter color worms (red, and rainbow) are subject to a negative population pressure because they stand out in the grass.
f. The results show that the population of green worms will grow over time while the bright color worms will decrease over time.
g. With the ability to see color and vision acuity the predatory birds seek the bright worms because they stand out from above. If the birds are looking for easy food they will go for the bright worms leaving the green worms because they blend into the ground. If the feeding times are at night then the birds will not be able to see the dark worms and will go for the bright worms. But if it is at the day the worms may be sought out differently.
h. In school grounds we fed on the brighter color worms would be more sought out and disappear over time. The population would then be dominated by green and brown worms. In 10 years the entire population would be dark worms because they are the ones that can sustain over time.
