The purpose of this lab is to examine biodiversity of an assigned transect at American University.

The transect is located in the northwest corner of American University between Butler Pavilion and Hughes hall and is marked by four popsicle sticks labeled with numbers 1-4. It is approximately 20 by 20 feet containing sidewalk on both sides of a patch of grassy land, containing trees, plants, and lamp posts.

The five abiotic features observed in the transect include a two metal lamp posts, littered ribbon, sidewalk, pebbles, and a cigarette bud. The five biotic features observed include a small black squirrel, a human between the ages of 18 and 22, seven large trees, several small ferns, and weeds. Their specific location is indicated on the aerial map below.

After observing the abiotic and biotic features above, a 50 mL sample of soil and leaves was taken from the transect to create a hay infusion. The hay infusion will be used to examine the different species of bacteria, archaea and eukarya that live in the transect.
