The Study of the Evolution of the Volvocine Line and Transects at AU -January 14, 2015
- Purpose:
To recognize how natural selection correlates with the evolution of different species and to formulate observations about my own sample niche. During this experiment, we looked to observe unicellular organisms and protists in our Hay Infusion culture. I think my Hay Infusion culture will contain evolutionary organisms in it’s soil.
- Materials and Methods:
-Slides of Chlamydomonas, Gonium, and Volvox
-Scientific Microscope
-Sample of my transect
-Protoslo
-50 mL conical tube
-0.1 gm of dried milk
-Plastic Jar
-500 mLs of deerpark water
-Graduated cylinder
- First,I observed the slides of Chlamydomonas, Gonium, and Volvox.
- Then, I recorded the number of cells, the colony size, the specialization of cells, the mechanisms of motility, and whether the specimen was isogamous or
oogamous for each specimen.
- I drew pictures of how each of the specimen looked under the microscope,
4. I observed and drew a picture of the area of my transect and recorded what my transect contained.
5. I used a 50 mL conical tube to take a soil/vegetation sample of my transect.
6. Back in the lab, my group and I measured 500 mLs of deerpark water with a graduated cylinder. And placed it in the plastic jar.
7. Then, my group and I placed 12 grams of the transect sample and 0.1 gm of dried milk in the plastic jar.
8. We mixed the contents of our Hay Infusion Culture for 10 seconds and removed the lid of the jar.
Data and Observations:

Tall Brushes Transect:

Conclusions and Future Directions: This data from transect supports that there is living organisms in my Hay Infusion culture. However, I am unsure about what specific organisms. Next time, I want to put more vegetation in my transect soil sample.
Description of Transect:
Abiotic: snow, dirt, water, metal post, concrete Biotic: leaves, bushes Location: inbetween Bender Arena and the Amphitheater Topography: near steep area, is not on a hill
