Observations of micro aquarium 22 Oct 2013

Observations:No real change in the aquarium in the past seven days.  The blue that I observed in the tear drop shaped structure in the aquarium seemed a little less blue (see Fig 2.). The water is clear with no movement observed. There do not appear to be any growths on either the utricularia gibba or the amblestegium varium.

Fig 2.

This is a teardrop shaped growth on the utricularia gibba.  It appeared more blue on the 15th.  This picture was taken in the lab at Hesler Biology rm 504 position #1 on 22 Oct 2013.

Observations of micro-aquarium 15 Oct 2013

Method:

I setup a micro-aquarium utilizing water, soil, and plant material from the Holston river located  along John Sevier Hwy under I 40 Bridge Partial shade exposure Holston River water Shed N36 00.527 W83 49.549 823 ft. This sample was collected on 10/13/2013 (see Fig 1.).

I added utricularia gibba and amblestegium varium to the water from the Holston.  The utricularia gibba was collected from south shore of Spain Lake (N 35o55 12.35" W088o20' 47.00), Camp Bella Air Rd. East of Sparta Tn. in White Co. and grown in water tanks outside of greenhouse at Hesler Biology Building. The amblestegium varium was collected from Natural spring. at Carters Mill Park, Carter Mill Road, Knox Co. TN. Partial shade exposure. N36 01.168 W83 42.832. Both samples were collected on 10/13/2013.

Observations:

There was no movement observed within the micro aquarium.  Most of the structures within the aquarium are green.  There is one exception and it is a tear drop shaped structure that is blue in color and connected to the utricularia gibba.  The amblestegium varium was unremarkable.
