Design a simple, manipulative experiment to test the hypothesis that synthetic fertilizers in the environment influence the population density of the salamander, Ambystoma tigrinum. Your experiment can have no fewer than two treatments and no more than four.
State your hypothesis.
Briefly describe your experiment. Address the following:
Is it a field or lab experiment?
What are the treatments, how are they set up, and what differentiates them?
How many replicates of each treatment will there be?
What are the standardized conditions of your experiment?
C. Identify the independent variable, including units, in your experiment.
D. Identify the dependent variable, including units, in your experiment.
E. Identify at least one control treatment and explain its specific role in the experiment.

- 1 Louseous Japanicas The first serious outbreak of this lice epidemic was officially noted on December 7, 1941, at Honolulu, T. H. To the Marine Corps, especially trained in combating this type of pestilence, was assigned the gigantic task of extermination. Extensive experi- ments on Guadalcanal, Tarawa, and Saipan have shown that this louse inhabits coral atolls in the South Pacific, particularly pill boxes, palm trees, caves, swamps and jungles. Flame throwers, mortars, grenades and bayonets have proven to be an effective rem- edy. But before a complete cure may be effected the origin of the plague, the breeding grounds around the Tokyo area, must be completely annihilated.
