Day 2: Surprises in the Tank

Tuesday October 23 turned out to be very interesting! After almost three hours in the lab I discovered many different organisms and named a couple.  The outward appearance of the tank did change a little bit.  The dirt in the bottom made a little cloud mass right above the bottom and when I moved the water around it didn't shift.  So I decided to take a closer look and discovered that it appeared to be like a small root system.  I didn't identify it, but that is what it looks like.  

The next thing I did was scan the tank under the microscope.  One of the first organisms I ran across was the Vorticella sp. (Patterson, 2003).

Protozoa, Peritrichs: Oligohymenophora (Patterson, 2003)

 You can see the cilia on the bell, and they are blurry cause they're moving so fast.  If I tapped the glass of the tank it would contract at the stalk back into itself and the dirt. Vorticella sp. are single cell organsims, and their common, filter feeders that eat bacteria (Patterson, 2003). They have weath-like cilia around the broad part of the cell, or the "bell shape" (Patterson, 2003).

The next thing I found was a Spirogyra floating around in the water.  The colors here are very vivid green, which make it a green alga, and obviously the spirals are very distinct (McFarland, 2012).  Just another good find for me!   

Spirogyra

But the best thing I've discovered so far is my mystery organism.  The reason I say mystery is because I have yet to find something that will classify it.  

 It is very much alive, and when we disrupted the tank he retracted all the way inside his body.  Upon first glance we came to the conclusion it was a rotifer just a different type. (Stremberger, 1979)  But when I went back in the lab, I decided to continue trying to identify it and leave it as a mystery for now.  
More to come!
p.s (nov. 21, 2012) I think we decided it was a Hydra sp.  I wish I could have been able to further investigate it but I never could find it again!

Day 1: The Set Up

Wednesday my lab finally got to create our Micro-aquarium™ term project. I am very excited to discover what is floating around in my little tank and see how each organism works!  I decided to use the pond water from the University of Tennessee Hospital because I thought it may prove to be full of life, with the storm sewer sediment supplying the pond.  The pond has full sun exposure and the water was collected on Oct. 9, 2011 at Cherokee Trail. Knox Co. Knoxville (GPS:N35 56.305 W83 56.717 850 ft). (McFarland, 2012).

UT Hospital Pond

   The first day we just assembled the aquariums and added our water and plants.  I chose to add both of the plant specimens, I added mostly Amblestegium sp. which is a moss, and has partial shade exposure.  It was collected from Natural spring at Carters Mill Park, Carter Mill Road, Knox Co. TN. (McFarland, 2012) and I also decided to put one strand of Utricularia gibba L. in as well. It is a flowering carnivorous plant (McFarland, 2012).

My Micro-Aquarium™tank

Once the tank was assembled I put it under a microscope to observe what is happening in the beginning of the four weeks.  There were some small white organisms that I could see with my eyes and no microscope, but being up close is much better.  There were many little green dot organisms that moved rapidly around in the water, and appeared to be "attacking" the larger organisms.  The most interesting thing I saw was four horn shaped organisms that appeared to just grow out of the sediment.  They had cilia that were around the bell shape and they would move back and forth like they were in a windy field.  Unfortunately I did not get to identify them, but next week's observation should help me figure it out.
