List of organisms

1. Euchlanis sp. rotifer

2. Litonotus sp. 

3. Coleps sp.

4. Halteria sp.

5. Arcella sp.

6. Cyclops sp.

This week I noticed two large Cyclops sp. They were both visible without the microscope and were extremely large under it. Below is a picture of one.

There were also large amounts of green all over the MicroAquarium. I took a picture to show how much green was around the entire aquarium. Below is the picture.

I was also able to see the Euchlanis sp. rotifers (Pennak, 1932). The Coleps sp. were also still visible swimming around (Patterson, 1992). This concludes the observations of this MicroAquarium.

5. Arcella sp.

6. Cyclops sp.

This week the life was still moving rapidly around. I spotted many of the same organisms, specifically the Euchlanis sp. rotifers (Pennak, 1932). and the Litonotus sp. (Patterson, 1992). There were many green pigments, many of which looked like small weeds. The amount of green growth was increased significantly. Another new discovery was an organism that could be spotted moving without a microscope, a Cyclops sp. There were no pictures taken this week, but I will post more next week.

List of organisms

2. Litonotus sp. 

3. Coleps sp.

4. Halteria sp.

5. Arcella sp.

This week a food pellet was added to the MicroAquarium. This increased the amount of living organisms greatly. I was able to see many Euchlanis sp. rotifers swimming around and them eating a dead organism. The Litonotus sp. was also seen again, looking the same as last week. Overall, the MicroAquarium had much more life and I was able to identify some new organisms.

The image below is a Halteria sp. (Patterson, 1992).

The image below was identified as a Arcella sp. (Patterson, 1992).

Below is the Euclanis sp. swimming (Pennak, 1932).

List of organisms

1. Euchlanis sp. rotifer

2. Litonotus sp. 

3. Coleps sp.

This week in observations I observed many small ant like things moving. When I got a closer look I discovered that their were live rotifers. Below is a picture of the Euchlanis sp. rotifer (Pennak, 1932). This organism moved in a jerky motion and very quickly. It stayed between the two plants not near the leaves. 

I also discovered a dead Euchlanis sp. rotifer that was being eaten by multiple Coleps sp. (Patterson, 1992). Below is a video.

The final organism identified was a Litonotus sp. (Patterson, 1992). It is a worm like structure that stayed near leaves and moved in a worm-like movement. The image below is the Litonotus sp.

Week 1

                                                                    BLOG 1
1. The water source I used in my MicroAquarium was number 5. It was from Meads Quarry, Island Home Avenue, Knoxville County TN. It had partial shade exposure. Rock Quarry N 35 57. 162 W83 51.960 880. This sample was collected on the 13th of October in 2013. (McFarland, 2013).

Included inside the water is Utricularia gibba and Amblestegium varium (Hedwig) Lindberg (McFarland, 2013).

                               This is the image of my MicroAquarium on Day 1.

Observations: While observing my MicroAquarium on Day 1, I noticed many black dots moving around in circles. There was also a green grass like organism that moved similar to a butterfly. There were many ant like organisms near the dirt on the bottom. I also observed brown ovals swimming and a clear worm that moved very quickly. The water had hairlike substances all throughout it and the last observation was a very fascinating insect larvae that was being sucked in and out of a leaf.
