Purpose:In this lab we began our study of a, roughly, 20 by 20 meter transect of land here at American University. From that transect we will take a soil and plant life sample, create a Hay infusion from the sample, and then discover what type of protists are found in our transect. By collecting samples from our transect, and observing it over several weeks we are able to study the community living in the transect. Through our study of the community in our transect we can discover the different niches, or the precise environmental necessities in their ecosystems, that the organisms have. All of this observing of organisms and our transect will aid in our study of biodiversity.
Materials and Methods:
• My group’s transect is number three, or the tall bushes transect.
• Group members observed the 20 by 20 area
• Drew an aerial view of the transect and took pictures of the area
• Collect soil and ground vegetation sample in a 50mL sterile tube
• Taking the sample back to lab we began to make our Hay Infusion
• Measure out 10-12 grams of the soil/vegetation sample
• Add the sample to a labeled plastic jar containing 500mL of water
• Measure out 0.1 grams of dried milk
• Add the dried milk to the soil and water mixture
• Put the lid on the jar and mix the contents of the jar together for about 10 seconds
• Take the lid off the jar and leave it in the lab for the week
Data and Observations: Within our transect we observed many abiotic and biotic factors in it. In our transect some of the biotic factors we observed were the bushes, trees, squirrels, birds, and spiders. Some of the abiotic components were rocks, metal plaques, the soil, snow, and we even found a rat trap in our transect.

Conclusions and Observations: Due to the several biotic components in our transect there will likely be many protists in our hay infusion. It is unlikely that our transect will change drastically over the next few weeks. So the abiotic and biotic components in the transect should remain the same.
