When I got to the lab today. I noticed my aquarium not having half of its water. This was much more than usual. I'm assuming that either someone knocked it over or the heat lamps were turned up a bit evaporating more water. The only organism that showed to have and increase instead of a decrease were the Rotefers. They were much more abundant than they were in previous weeks. The only organisms still present in any significant number were the Vorticella, the Amoebas, and the seed shrimp, though the Vorticella have become less colonized and in fewer number. The plants are becoming more of a yellow color due to the lack of chlorophyll consumed by the different micro organisms. The units were undoubtedly consumed by the microbes, as the organisms have been seen eating the plants and also having parts of the plant in them, as well as a by their increase in number. As a result, the plants appearance under a microscope are becoming much more clear and naked.

The larger nematodes are getting much larger while about 20 or so new ones are gathering mostly in the soil. The decaying corpse of organisms that the vorticella were have nearly been completely consumed. I assume that the vorticella played a key part in this. The Volvax glabator are larger and in greater abundance staying more toward the soil. The plant are becoming less green and the organisms aren't in as great abundance around them as they were. The seed shrimp are also multiplying in both number and size. In the bottom left corner of the tank I noticed an organism that appeared to have to rotor heads on it they were turning all the time. Dr. McFarland helped me identify this as a Philodina carotifer. This can be referenced to the chart Micro Invertebrates, Ward's Natural Science, 1998.

The organisms were in greater abundance of all kinds. The larger paramecium were mostly staying around the soil in the bottom of the tank but were not limited there. There were a lot more of the same organisms but vary from very small to large. There also were what looked to be some dead Daphnia on the soil. Small long worklike organisms were wiggling around inside of a node of plant A. Vorticella were found in more abundance on both plants and dead organisms near the soil. I noticed a cyclops trying to dig it's way into the glue holding the tank together. I noticed a few seed shrimp and IDed another from a Fresh-living book, Diflugia Corona.
