Make a figure for your experiment that would be included in the results section of a scientific paper. Your figure should include labeled axes and an appropriate caption. Copy/Paste this figure into your document; do not use a screen shot. Instructions for how to make graphs is provided in Appendix D.

Provide a table showing the results from your statistical analysis. This should be appropriate for inclusion in a results section of a scientific paper. Remember, do not report raw data.

Write a paragraph (5-7 sentences) describing the results you observed in the experiment that would be appropriate to include in the results section of a scientific paper. Refer to the instructions provided in the Scientific Writing section of Lab I for instructions on suitable content. Ideas to consider: What happened during the experiment? Were there any noticeable trends or patterns in the data? What were the statistical results from the experiment?

Write a paragraph (5-7 sentences) appropriate for the discussion section of a scientific paper. This section should explain how and why you got the results, and their broader implications. Refer to the instructions provided in the Scientific Writing section of Lab I for instructions on suitable content. Ideas to consider: Did the results reject or fail to reject the null hypothesis? Why? Did the behaviors observed in the pill bugs reflect a response that would increase their chance of survival? Would these be considered an adaptation? What does this tell you about animals and natural selection? What kind of experiment would you conduct to build onto this knowledge?

The experiment selected for this analysis involved assessing the behavioral response of pill bugs to environmental temperature variations. The primary objective was to determine how temperature influences their activity levels and movement patterns, which could provide insights into adaptive behaviors relevant to survival and ecological interactions. Data collected showcased measurable differences in pill bug activity across temperature treatments, with increased activity observed at moderate temperatures and decreased movement at extreme temperatures. The statistical analysis, utilizing an ANOVA test, revealed significant effects of temperature on pill bug behavior (F(2, 27) = 5.34, p = 0.009), confirming that temperature notably impacts their activity levels.

In the results of the experiment, pill bugs displayed a clear trend of heightened activity at moderate temperature levels, with activity decreasing as temperatures became either too hot or too cold. The graph depicted a bell-shaped curve, illustrating peak activity at an optimal temperature of around 20°C. The statistical analysis supported these observations, with a significant difference noted between the different temperature treatments. Specifically, pill bugs exposed to 20°C exhibited significantly more movement than those at 10°C and 30°C. These findings suggest that temperature plays a critical role in shaping pill bug behavior, which may be linked to their physiological and ecological needs. Overall, the results align with previous research indicating that ectothermic organisms respond markedly to ambient temperature changes.

Discussing how and why these results were obtained, it is likely that pill bugs regulate their activity based on temperature cues to optimize their survival prospects. The observed bell-shaped response curve is characteristic of ectotherms that exhibit thermal preference behaviors, increasing activity within their optimal temperature range. This behavior could be an adaptive response, increasing their foraging efficiency and reducing exposure to harmful environmental conditions, thereby enhancing survival. These responses support the idea that natural selection favors behaviors that enable organisms to cope with environmental variability, ultimately contributing to their evolutionary fitness. To build on this research, a future experiment could examine how humidity or moisture levels further influence pill bug behavior, providing a more comprehensive understanding of their adaptive strategies in natural habitats.
