Water currents in the microcosmos

Watching different water samples under the Foldscope, I was fascinated by the variety of constantly active minute organisms, each with their unique ways of capturing food. Their feeding process, driven by tiny cilia, creates competing water currents on a single glass slide. Each minute animal makes its own whirlpool to suck food into its mouth…

Exploring the ‘Dagad Phool’ ecosystem

It started with my wondering about the pictures of tardigrades on the new foldscopes. Called the “world’s most indestructible creatures”, I learnt that these hardy champions survive for 30 years without food or water. They have endured extremely cold, irradiated journeys, riding on the outside of space-ships… and you can find them just by soaking…

Day 7: Lichen cultures

Continuing from my previous post, I am going to try and keep an eye on the succession of life in my lichen cultures. For this, I have 6 different lichens collected from different trees put into petridishes containing RO water. Below, I categorize all life I could see after 1 week. Here are results from three…

Foldscoop 1:3. Long-term Lichen suspensions

Laziness is a good thing; sometimes. Previously I had posted on observing tardigrades, ciliates and nematodes (1, 2)  in Lichens. It so happened that due to a hundred obstacles that life so often places, I  forgot to observe the lichens suspended in mineral water for about two weeks. By this point, the water turned dark brown…
