Question Do roly polys react more positive to wet dirt with no roly polys or to dry dirt with roly polys? Methods We began by deciding how we wanted to conduct our experiment. We then agreed on using the choice chambers to show whether the roly polys would choose their preferred environment over social factors. To do this on one side of the choice chamber we put the roly poly’s normal environment which is wet dirt and on the other side we put dry dirt with about 5 other roly polys on this side. To make sure these roly polys stayed on the correct side, we decided to use a smaller ruler to block the way out. We would then randomly choose a roly poly to put in the middle of the choice chamber. We gave the roly poly at least 5 minutes to make …show more content…

Three roly polys went straight to their preferred environment and 7 went towards socialization. More roly polys went toward socialization versus a preferred environment (wet dirt). Observation As you can see, most of the roly polys that were randomly selected to be placed in the middle of the choice chamber decide on socialization which were 7 out of the 10 roly polys. The other 3 picked environment over the social environment. Justification My claim states that roly polys prefer socialization factors over favored environmental factors. Three pieces of evidence that support my claim are that 7 of the 10 roly polys selected socialization factors with the unpreferred environment, only 3 of the 10 roly polys chose environment, and roly polys did not chose the controlled group which is the middle of the choice chamber having no dirt or other roly polys. As you can see these results in figure 1, ten replicates were ran during this experiment. We randomized this experiment by choosing different roly polys to be placed in the middle of the choice chamber each …show more content…

One of the reasons previously stated is 7 out of the 10 roly polys selected socialization factors with the unpreferred environment. To support this, Physiological Entomology, "Effects of Group Size on Aggregation against Desiccation in Woodlice (Isopoda: Oniscidea)," (Broly, Devigne, Deneubourg, & Devigne, 2014), states, “Aggregation in terrestrial isopods, a behavior that results in the formation of dense clusters, is readily accepted as a mechanism of resistance to desiccation.” This translated into clumps of roly poly’s performance results in the creation of solid groups and is freely known as a device of conflict to dehydration. This supports my claim because it shows that roly polys will take dehydration and solid groups over their normal
