In the top portion of our sample we found chlamydomonas and euplotes sp. In the middle portion we found Bursaria truncatella and paramecium aurelia. In the bottom sample we found paramecium Bursaria and vorticella.

January 29 - Identifying Algae and Protists
Our culture had floating white stuff in it, which is expected to be mold. The sample smelled very strongly and badly and the water was murky. There was distinct differences between the top, middle, and bottom section of the hay infusion sample. The top had a slim white film cover, the middle was cloudy green with some leaves and grass floating, and the bottom was densely populated with leaves, muck, and other algae.
In the top portion of our sample we found chlamydomonas and euplotes sp. In the middle portion we found Bursaria truncatella and paramecium aurelia. In the bottom sample we found paramecium Bursaria and vorticella. I have included sketches of both the paramecium burs aria and bursaria truncatella.
January 22, 2015 - Biological Life at AU
Our transect is located in the center of campus in the amphitheater woods. The location is densely populated with trees and other microorganisms given the nature of American University's campus in general. There are also some built components to the transect, including a paved sidewalk, various benches, and some lamp posts. The transect is also often visited by squirrels, rats, raccoons (I previously lived in Leonard Hall near here and can speak for this), insects, and college students.
As I touched on previously, the biotic features in our transect include leaves, trees, bushes and brush, squirrels, rats, raccoons, and humans. The abiotic components of our transect include metal lamp posts, a concrete sidewalk, stones, cigarette butts, and a discarded ribbon (litter). As indicated in the image, the leaves, trees, brush and bushes are found in the center of the transect, which is overall surrounded by the concrete sidewalk. All the animals I mentioned earlier visit the center of the transect, but humans are assumed to remain on the sidewalk and benches. The lamp posts are located directly in the center of the transect as well, surrounded by many trees. The transect has a few inclines and levels.
