Week 5

Week 5
This week I found one new organism that appeared in large numbers.This organism was a Pinnularia sp. (Carter-Lund, Lund 1995). They are a green photosynthetic algae. They were near the bottom of my aquarium and drifted around. The Aeolosoma sp. are every where in my aquarium(Ward & Whipple 1918). There numbers have grown significantly. They move around all over the tank. The Spiro Gyra sp. have grown very long(Rainis and Russell 1996. There are three individual Spiro Gyra sp. at the bottom of the tank. They are green and non-motile. There were Bodo sp. at the top of the tank(Rainis and Russell 1996). They are not green, and motile. I am still surprised about the lack of species diversity, but I think it can be explained by the hostile takeover of the Aeolosoma sp.
