Week 5: Observations


On November 14, 2012 towards the bottom of my Micro Aquarium there were multiple strands of cyanobacteria, Actinosphaerium sp., and diatoms. The Actinosphaerium sp. is shown to the left that shows the them in the division process (Patterson). The diatoms appear to be a yellow-brown color and are shaped in the form of gold bars attached to each other and some are just a single bar. At approximately 100x magnification there are 30 clusters per 50 square micrometers (Rainis and Russell) In addition, the midge that was observed during my first week of observations had grown nearly double in size and has acquired hairs on the tail sections of the body. The midge lives in the depths of the soil layer by convulsing its body to bury it self.
