Welcome to our carnivorous plant speed contest! Four carnivorous genera qualified for our speed contest and they all give their best. Is Aldrovanda able to keep up even against the water resistance? How well does the famous Venus flytrap? Does the sundew that is usually regarded quite sedate have a chance at all in this competition? And what's the story with the southern bladderwort? Examined in detail with the help of time lapse as well as slow motion shots. English subtitles provided, enjoy! Special thanks go to Dr. Simon Poppinga and his team of the Plant Biomechanics Group of the University Freiburg as well as to Dr. Jan Schlauer for his kind support.-

Hi guys. I'm posting some more pics because now I have more plants. I swapped some Australian alvodandas for some Japanese ones. Here the green Japanese side by side with the Australian. There is also some U. gibba Two Japanese Bonus pic. My P. primuliflora

Hi guys, this is my out-door tank . Notice that it has clay on the bottom (it is important to give Boro to the plant), a thermometer / heater, CO2 injector, monocots (to inject O2 and CO2 in the water, and consume excess of nutrients and prevent algae growth), and water from a pond full of aquatic organisms (food). The water is dark because of the leaves of Drosera, Juncus, Carex sp. and others in the bottom. Tannin appears to have a role in plant development, and is found in its natural habitat. They came still green. Juncus, U. gibba and food... I mean, Biomphalaria sp. They soon became red, and look, they have flowers. Temperatures here are around 32 oC.

Trap diversity and evolution in the family Droseraceae Simon Poppinga, Siegfried R.H. Hartmeyer, Tom Masselter, Irmgard Hartmeyer and Thomas Speck A new review has been published in PBS (Plant Signaling & Behavior) and is now online (open access, link below). Recent investigations revealed how the snap-traps of Aldrovanda vesiculosa (waterwheel plant) and Dionaea muscipula (Venus’ flytrap) work mechanically and how these apparently similar devices differ as to their functional morphology and shutting mechanics. Recently, it was also shown that there exists a higher diversity of different tentacle types and trap configurations in Drosera than previously known which presumably reflect adaptations to different prey spectra. Based on these recent findings, we finally comment on possible ways for intrafamiliar trap evolution. http://www.landesbio.../article/24685/
