Archeta
The experiment was carried out to determine whether Acheta domestica has a preference in the amount of light intensity it receives to determine if lux values has any effect on its times of activities during the day. The hypotheses were as followed: Ho: Light intensity plays no role in the Acheta domesticus’ choice of habitat. Ha: Light intensity plays a role in the Acheta domesticus’ choice of habitat. The statistics used to analyze our data was the chi -squared test, since we had discrete data.
The experiment was carried out as a choice experiment between three different light intensity values. The three choices were the light intensities provided by cheesecloth, black and transparent covers. The lux value under the black was measured to be the lowest (37 lux), followed by the cheesecloth (90 lux) and then the highest value was under the transparent cover (115 lux). The experiment was carried out by placing the organism in a circular glass bowl that was surrounded by black filmy paper and then placing the light intensity divider on top of the bowl; refer to figure 1 for illustration of setup. The organism was then given three minutes to roam around and make a selection. The choices were randomized by the fact that there were three simultaneous treatments occurring at once, so each starting point choice for a treatment was randomly different from the others and the direction the organisms faced when placed was randomized by the way it dropped into the container. The response of the organism was measured by its position once the three minutes were up, however if the organisms was still in motion when the time period was up the response was then measured as no choice.
There were two trials conducted in total, each with 24 replicates and each with three treatments happening simultaneously. The second trial was modified by replacing the black filmy paper surrounding the bowl by aluminum foil and then adding rectangular
