Protozoa in healthy Rumen Vs Rumen acidosis

Rumen acidosis is a serious condition by which there is a drastic decrease in the pH of the rumen in cattle. Rumen lactic acidosis develops in ruminants that have ingested large amounts of feed rich in carbohydrates. It results in the production of large quantities of Volatile fatty acids (VFA) and lactic acid, thereby decreasing…

Help me identify these ciliates and flagellates

Without much ado, here are 5 unicellular eukaryotes that were growing in my lichen suspensions. These emerged after almost 4 weeks. I took these videos at the beginning of the year,  and only now found time to collate them. Could you help me identify these? BTW, even after 4 months, I have nematodes and rotifers thriving…

Tardigrade and friends

I have been greatly inspired by the Stanford Tardigrade post and want to explore the local lichens for similar associations. Initially, I was just focused on finding Tardigrades, but then everytime I picked up a lichen for foldscoping there were other life forms that were consistently observed in the same environs. I then thought that I  should report…

Exploring a pond water sample with a DC micronaut- part-2

Sometime back I had posted a series of videos on a Vahlkampfid amoeba. This emerged from a long session I had with DC-Micronaut Reethi while we were exploring various foldscope tricks and also deciding on workshop content.  In that session we saw several other gems and I didnt get myself to post them until now….

Ciliates in our backyards – Suctorians 

Amongst enigmatic ciliates you will discover through your Foldscope; Suctorians hold a special place. Strangely looking like stars – in the first look they don’t seem to be doing anything. They just sit; and wait.  But in this patient wait lies a secret.. Capability to capture and eat many other ciliates by a mere touch….

Ciliates in our backyards – Euplotes 

After following notes from @Laks on hay cultures.. Culturing ciliates: The Hay Infusion, Day 8 I decided to create my own hay cultures; and watched them grow. It’s been fascinating to see the cultures grow; and I see new things almost on a daily basis.  I want to quickly share possibly the largest Euplotes I…

Identifying ciliates – guide key 

It’s a thrill to find an organism in a natural setting ; and wonder if it’s something science and human society knows about or an undescribed, never before seen species. As a young Foldscope scientists, early on, you should not worry too much about this fact – since you are making discoveries without others telling…

Imaging “live” parasites (Ambiphyra) on “live fish”

Today, I am excited to share a wonderful world of live imaging with the Foldscope community. It is always a thrill to watch “live” biological processes; since they are dynamic and evoke a sense of life. Something is so special about living matter, it is counter intuitive in nature. Thus is crucial to prepare your…

Day27: Saltatory Halteria

The pond water continues to do pretty well in my bottle with  rotifers, daphnias and flatworms in a nice equilibrium, suggesting that the water is still not depleted of dissolved oxygen. The population dynamic is really interesting and I wish I could count each of these animals as they increase or decrease in number. Perhaps one could…
