Observation #4

In my fourth and last observation of my MicroAquarium took place on November 13. I retrieved my MicroAquarium from the bin labeled my lab section and proceeded to place it under a microscope. In this observation I saw many organisms that I have been observing in previous blog entries. The organisms I looked at were Tachysoma, and more Euplotes. They look like they have multiplied and gotten bigger. Everything else in the MicroAquarium looked similar to what I observed before.

I observed a new organism in this observation and that organism is Vorticella. This organism has a long flagella, which is very distinct.

Observation 3

Observation #3

My third observation of my MicroAquarium took place on November 6. After retrieving my MicroAquarium from the bin assigned to my lab time, I placed my MicroAquarium under the microscope. In this observation I was quick to spot out Tachysoma. I talked about Tachysoma in my last observation, but in this one I took a picture. 

Further into my observation I came across a new organism that I Haven't seen before. That organism is Centrophyxis. They look like brown circular organisms with a circular inside. I saw many rotifers in my MicroAquarium in this observation also.  My MicroAquarium is full of life with the organisms that I observed in previous blog posts, and the new organisms I found in this blog post.

Observation #2

My second observation of my MicroAquarium under the microscope took place on October 30. After retrieving my MicroAquarium from the bin assigned to my lab section, I placed my MicroAquarium under one of the microscopes. As i was looking at my MicroAquarium i observed many of the same organisms that I did in my last observation. I saw many Euplotes and Ureocentrum. It seems as if they are more abundant in this observation. 

I found the food pellet that Dr. McFarland put into my MicroAquarium. The food pellet is a Beta Food Pellet. "Atison's Beta Food" made by Ocean Nurtition, Aqua Pet Americans, 3528 Wrest 500 south, Salt Lake City, UT 84104. Ingredients include: Fish meal, wheat flower, soy milk, krill meal, minerals, vitamins and preservatives. Analysis is: crude protein 30%, crude fat 4.5%, crude fiber 3.5%, moisture 8% and ask 15%. 

The food pellet was full of life. As I observed it there was many Euplotes swimming around it. There were so many I couldn't count them all. I saw a new organism that I haven't seen in my MicroAquarium before. That organism is Tachysoma. There were many swimming around the food pellet. I did not get a picture for this posting, but I will in my next observation.

Observation 1

In my first observation, I got my aquarium from the place they were stored. I then proceeded to take the lid and stand off of my aquarium and placed it under a microscope. I was very surprised when I saw new organisms in the aquarium. Further in my observation I started to identify the new organisms I found. These organisms are  Euplotes, and Ureocentrum. I then went on to take pictures of the organisms The plants in the aquarium look normal as they did when i set it up.

Euplotes- A common and wide-spread hypotrich ciliate. Euplotes have ventral cirri that help them move over a substrate. They have adoral zones of membranelles which are located on the front o the organism, that draw a current of water under the cell towards the cytosome. Suspended particles may be removed by the ciliate from the current.

Ureocentrum-  Freeliving Fresh Water Protozoa Figure 388

This genus behaves as spinning top. It has a tail that spins and attaches loosely to debris and spins around. Ureocentrum mostly feeds on suspended bacteria, and it is related to a Paramecium. Like most members of its genus it has trichocysts and a contractile vacuole with collecting canals.  

Day 1 Micro aquarium

Day 1- I set up my microaquarium using the glass aquarium provided in class along with a base and a lid to seal it. I went on to fill the aquarium with water from the Tennessee River at boat ramp across from Knoxville sewer plant. Neyland Dr. Knox Co. Knoxville TN. Full sun exposure. French Broad and Holston Rivers water Sheds N35 56.722 W83 55.587 813 ft 10/12/2014. I then added Utricularia gibba, which is a carnivorous plant to the aquarium. I then added Amblestegium varium which is a moss collected from natural spring at Carters Mill Park in Knox county TN. I put the aquarium under the microscope and observed the sediment in it and looked at the plants added. I saw a nematode swimming in the aquarium. I did not see any other organisms.
