Biophysical Ecology
There are many patterns that can be observed throughout our environment. In this experiment, the temperatures of organisms in a biophysical environment were analyzed to see if a pattern could be recognized that was related to the behavior of an ectotherm. An ectotherm is an organism that relies on the environment to regulate its body temperature. Organisms such as Pseudemys (turtles) and Lacertilia (lizards) are examples or ectotherms. After arriving at Maxcy Gregg Park and analyzing the temperatures of four microhabitats within two habitats with infrared thermometers, the temperatures were compared between the microhabitats. Then, one habitat was chosen to analyze the temperatures between

The group then chose one of the two habitats to further investigate its microhabitats. The habitat with the biggest temperature difference between the infrared readings of the two microhabitats was the one chosen by the group. The group used ten I-buttons, temperature-recording devices, and ten marshmallow Peeps to analyze the temperatures of ectothermal organisms within microhabitats.
The small I-buttons were taken out of ice water and pressed into a hole that was made with then end of a pen cap into the bottom of the marshmallow Peeps. Then five were immediately placed into each microhabitat for twenty minutes. The time that the Peeps were placed into the microhabitats was immediately recorded. Twenty minutes later the stop time was recorded and the group took the I-buttons out of the Peeps, recorded the serial numbers of the I-buttons corresponding to the microhabitat they were placed in and then returned the materials to the lab TA and the Peeps were discarded. Back in the laboratory, the data from the I-buttons was collected and put into a spreadsheet by a TA and put of for the lab groups to use to use the data. The groups gathered at a computer to put the data from Maxcy Gregg Park into Excel to eventually be able to run an ANOVA. First, two charts
