Observation of Micro-Aquarium 12 Nov 2013

The traps of the utricularia gibba (a carnivore) have lost their pigment altogether.  You may recall that I took a picture of a utricularia gibba trap for the 22 Oct observation (Fig 2.). The plant appears to be degrading.  There is quite a bit of debris in the aquarium this week. Some of the debris are dead protists; while other parts of the debris are the leaf that was placed in the aquarium as food which has broken down (disintegrated).  There was a lot less movement in the aquarium this week.  I did capture a video but was unable to convert it to the proper format for this blog entry.  Microscopic life is still teaming within the aquarium but not to the extent that it was a week ago. The amblestegium varium still appears green and viable. 

Observation of Micro-Aquarium 5 Nov 2013

The aquarium is teaming with microscopic life! There are orange globular spots around the utricularia gibba.  I also captured a video of Chaetonotus (Pennak) which is a Gastrotricha as seen in figure 5. The most common life in the aquarium appears to be the Paramecium Aurelia (Rainis, Russell). The teardrop shaped growth in fig 2. of the 22 Oct Blog entry, appears to have died.  It has changed color from blue to gray.

Observations of Micro-Aquarium 29 Oct 13

On Friday October 25, 2013 "ONE" Beta Food Pellet was inserted into each microaquarium (http://botany1112013.blogspot.com). This week there was much more movement in the aquarium. The first structure that I witnessed was a Colpidium (Fig 3.) which is common in organically enriched sites (Patterson, 151). As I was observing the Colpidium a Uronychia (Patterson, 124) moved passed but I was unable to get a photo due to the speed of the Uronychia.  However I did manage to catch a video of a Limnias rotifer (Pennak, 218)( (Fig 4.).  There were smaller structures moving within the aquarium but I was unable to catch a photo of them without distortion.
