Samantha VanderVeen Mrs. Flegel AP Biology 10 September 2012 Environmental Effects on Isopods In this lab, there was testing of three different environment variables that could affect the lifestyle of an isopod. We used household items such as makeshift tin foil containers, strawberries and potatoes, wet paper towel, a lamp and piece of brown cardstock, along with about 50 isopods to participate in this experiment. Allowing us to determine what kind of environment isopods prefer. We were able to conclude that isopods prefer a dark, damp atmosphere with a large supply of a starchy food source. As a whole, the class was asked to create and carry out at least three environmental differences that would help create and single out variables to help find the most desirable environment for the isopods. With background research, isopods are perceived as loving areas with moisture, preferably under rocks and soil, with decaying material for consumption. With this information, and collecting bugs, we were told of a few techniques and different variables to keep them alive until needed for the actual experiment. Our three trials with isolated variables were experimenting with different food sources, consisting of starch and sugar, whether they are attracted to a damp or dry environment, and one of which had a light and dark side. Our hypotheses were that the isopods would prefer the strawberries with the glucose in them, along with a damp environment and a longing for the dark. To go through with this experiment, we recreated three containers out of tin foil. In each we placed about twelve isopods after creating the living conditions. One consisted of both strawberries and potatoes. In another we kept one side damp with a paper towel, and the other side dry. And for the final container we laid a piece of cardstock over half and a lamp over the other, with only a gap to
