Hi Guys, the Salton Sea (an ecological enigma) is absolutely amazing in so many ways. This Sea is often mentioned on the AP test because of it's connection to the Colorado River and agriculture, and as it's importance as a migratory stop for Birdies. Please watch the following short video and respond to the questions below. http://www.youtube.com/watch?v=BKsK13NDkpg

1. describe the formation of the Salton sea and include the historical information about it, going back to Lake Cahuilla.

2. What keeps it going to this day?

3. What is endangering the sea?

Next please click on this link and read about California's water issues http://en.wikipedia.org/wiki/California_Water_Wars
please go the above article on wikipedia, read the article the answer the following questions: ( by the way, be sure to peruse the whole article)

1. Discuss how water was acquired by Eaton and Mulholland for the city of LA.

2. What does Mono Lake have to do with any of this?
Next please check out the following website and pick one other "water project" that is described in this website (other than the Owen's Valley) and explain/summarize it in about one short paragraph..... the water projects can be found under the tab "water topics" ----dams, reservoirs, and water projects

6. In the following phrase, identify both the biotic and abiotic factors " Low phosphorus (a nutrient) content in soil limits the growth of vegetation"
7. What are limiting factors? What would be one important limiting factor for a farmer who was planting corn? What would be the main limiting factor in the desert?
8. Chose any biome or ecosystem and name it, then tell one likely limiting factor specific to that biome.
9. Where would you find the process of chemosynthesis taking place?
**** I am attaching the power point presentation for this chapter....so you can see ahead of time what we will be talking about.

-First, read this: http://www.livescience.com/23026-global-warming-changing-world.html
I mean click on the link and then read ALL of the info :)
-Next pick two of the events listed (there are 8 total) and conduct further research on each of the three events using the links provided in the short explanation given or your book (ch 20) Find out more information and elaborate on what was mentioned in the news piece. For each of the two events, write up a paragraph on your findings....include the website you used. Paragraphs should be at least five sentences and should not just repeat the info given in the original news piece. To recap, that's a total of two complete, well-written paragraphs, use only your own words, and feel free to add commentary. Short paragraphs that are not original will not be considered for points.

For this assignment you will continue to answer questions about biomes,
see chapter 5 for reference and you can always use the Internet to find answers

Questions:
1. How do the various herbivore species in the Savanna ecosystem
reduce competition when it comes to eating?
2. In the tropical rain forest, there are 5 "layers" that describe differences in vegetation, can you please tell me a bit about the "top" layer and the "bottom" layer?
3. Compare/contrast the soil in the tropical rainforest with the soil in the
temperate deciduous forest.
4. Which biome would one find "conifers" in?
5.Read the case study on page 364 "OIL AND ANWR" and do some research on the ARCTIC WILDLIFE REFUGE....What is it, where is it? What characteristics of the tundra make this biome especially sensitive to human interference? What types of human activities would be taking place if we were to open this place up to drilling for oil? What do we use oil for anyway? What types of actions can we humans take to reduce our use of petroleum (aka oil) products?

6. Research the BARK BEETLE by reading the following article
http://www.nytimes.com/2008/11/18/science/18trees.html?pagewanted=all
give me two interesting facts from the article about what is happening to our
nations forests. This is a bit of a review
