utricularia-gibba

So yeah, low-techtank was right, the stuff was utricularia gibba and I got as much as I could find the fuck OUT of my tank.

Hopefully I got all of it, if not, I shall be monitoring - but thankfully, endler fry are big enough that I don’t think this is a danger to them.

fisholotl, I would eyeball those plants I sent you and make sure none of this stuff got on them. I don’t *think* it did, I didn’t see any on the bits I sent you, but I would double check.

Uh oh! The Aquatics!


Over the course of the summer, I acquired several aquatic carnivores -  Androvanda vesiculosa, Utricularia australis, and Utricularia macrorhiza. (I already had Utricularia gibba). I placed all these in an “extra” aquarium (it wasn’t really extra, but I needed somewhere to put them). I added a few non-carnivorous plants to the tank and placed it on my deck.

These plants survived the summer and fall outside and, having no where to put them inside, I decided to do an experiment to see if they would survive the winter. I figured that if they didn’t, I could probably acquire new stock next summer, if I got a proper setup
Unfortunately, the recent series of freezes and thaws resulted in the tank being demolished! Fortunately, most of the plants were frozen together, so I rescued them in a plastic bucket, but I’m not entirely sure what survived and what slipped through the bottom of the tank and through the deck. So, I’ll have to wait until spring to see what survived the mishap (and winter).
Aquatic Carnivorous Plants: Utricularia & Aldrovanda Tanks


I have a small aquatic carnivorous plant tank, seen above, which contains Utricularia gibba (mostly), and, thanks to a generous mailing I received yesterday, now contains Aldrovanda vesiculosa, Utricularia australis, and Utricularia macrorhiza. Most of what you can see in the above picture is, of course, not carnivorous (duckweed and some other plants), but necessary to help the water maintain the correct pH and composition to allow the carnivores to flourish. Below, you can get a side view:


I’m excited for spring, when I hope to see some yellow flowers, like the U. australis below, carpet the top of the tank. Of course, that’ll be nothing compared to the joy of having the Aldrovanda flourish. Hopefully, the conditions are right for such an event.


Utricularia gibba Wins 10th Annual Olympus BioScapes Digital Imaging Competition


A Utricularia gibba photographed by Dr. Igor Siwanowicz won the 10th Annual Olympus BioScapes Digital Imaging Competition this past December. 
Dr. Siwanowicz captured this photo of a U. gibba’s trap with microorganisms inside using confocal microscopy, which is an optical imaging technique used to increase optical resolution and contrast of a micrograph by using point illumination and a spatial pinhole to eliminate out-of-focus light in specimens that are thicker than the focal plane, meaning three-dimensional structures can be reconstructed from the obtained images.
Random Factoid: Dr. Siwanowicz used the cellulose-binding fluorescent dye known as Calcofluor White to visualize the cell walls of the plant.
