    Environmental Effects on Pillbug Behavior Catherine Liapes October 14, 2015 AP Biology- Pd.9 Mr. Angus Introduction: Before conducting this lab, I researched information on pillbugs and learned that pill bugs are commonly found in damp environments such as piles of leaves, or under logs. Although they are crustaceous, they can still spend their entire lives on land. They are about ¾ inch in length with seven pairs of legs, and multiple antennae. Pillbugs are nocturnal and mainly consume rotting vegetation. They play a role in decomposition because after feeding on decomposing plants, they return the organic material to the soil so it can be further digested into nutrients for growing plants. They are also able to remove toxic metals from the soil during the digestion process. Before beginning any of these procedures, my group and I hypothesized that the pill bugs will gravitate towards the chamber filled with water rather than the vinegar-filled chamber. We predicted that the bugs would display a negative chemotaxis and a positive hydrotaxis. With collecting this information, it allowed us to complete the directed steps to observe the general characteristics of pill bugs when influenced by different environmental factors. The purpose of this lab was to test the organisms’ chemotaxis and hydrotaxis. Chemotaxis is the is the movement of an organism in response to a chemical stimulus and hydrotaxis is the movement of an organism’s in response to moisture.…

    Analysis: There are several instances where the number of pillbugs in the light are equal to the number of pillbugs in the dark. It’s difficult to decipher a pattern in the data. The pillbugs seem very indecisive and continuously move between chambers. However, if one disregards the data where the number in light and dark are equal, there are three times where the amount in light is higher and only two times where the amount in dark is higher. Conclusion: In conclusion, there is not enough data…

    The purpose of the lab was to observe the environmental impact on the behavior of pill bugs (Armadillidium vulgare) by using the steps of the scientific method. . We placed two pill bugs in an enclosed space and recorded the amount of time they spent in two categories of living spaces: hard rocks or soft sphagnum moss. Despite predicting that they would have a preference for a softer area, both pill bugs spent more of their time in the rocks than in the moss. This suggests that Armadillidium…

    Pill bugs name is woodlouse. Climate change will have an effect on animals, plants, and humans. With climate change rising many animals are going to get extinct in the future. Pill bugs are small animals that can live under rocks, and when you catch one they always tend to rolled up into a small ball. Their body temperature has to match with the environment that they live on. Pill bugs always like to come out during the night because they preferred moist and dark places. Temperature is important…

    The purpose of this experiment was to be able to identify certain substances that the Armadillidium vulgare is attracted to or would be likely to move towards. The substances were three different liquids and three different solids. Another purpose of the lab was to learn the characteristics of an Armadillidium vulgare also known as a pillbug (Mader, 2013). The main topic was based on whether the pillbug would be attracted to certain substances, and the reason they’re attracted to it. The…
