3/20/06 Biol 6:50-8:45 Title: The effects of temperature, pH, and dieldrin on water stream life. Hypotheses: 1. If the temperature of the water is increased to 30 degrees C, most fish will not be able to survive nor reproduce. 2. If the pH reaches a level of 1, almost everything will be eliminated because the plants will have a hard time adjusting to the high levels of acid. 3. If levels of dieldrin reach .740, any organism that is exposed to the dieldrin will die. Results: 1. When the temperature was increased to 30 Degrees C only the stonefly, caddisfly larva, and mayfly larva were not able to survive. 2. When the pH level reached 1, bass, minnows, sunfish, stonefly, crayfish, frogs, and caddisfly larva all died. They all were organisms that were higher up on the food web. Nothing towards the bottom half was affected by the drastic change in pH. 3. When the amounts of dieldrin reached .740, bass, minnows, sunfish, daphnia, stonefly, and crayfish all died. Once again these were the larger organisms at the top of the food web and everything in the bottom half was able to survive Discussion:

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
