Things connected to observations in ecological context
Granite pebble stone from Merced river in Yosemite
By using the magnet tapped to the camera of my phone to connect only the lens module of the foldscope, I enabled a way to image the surface of the pebbles. Interestingly, I have seen some very fragile while structure. By breaking the pebbles, we can see an incredible difference outside/inside in terms of color…
Tiny Creatures under Foldscope, that has bloomed my Mind.
While working on these algal culture what i have observed that, there were lots of algal diversity in mats and wall scrapped sample, and these different habitat include different algal diversity ranging from coccus to filamentous forms.
Fungus on Bread under foldscope
The moldy bread that Mamta got from mess by explored using foldscope. I was sure it would be Rhizopus. But it turned out to be some other mold ——- probably Aspergillus species. I could see loose sores (conidia) spread all over.

Mysteries of Dal Lake, Kashmir – Part 2
After seeing the diverse flora in Part I, here I share the findings on the microbes in the water from Dal Lake. We thought we could find a dense composition of organisms if the water could be centrifuged. Sayantan, a graduate student in biology at TIFR Hyd helped me with this. We put 50 ml…
Mysteries of Dal Lake, Kashmir – Part 1
It all started when my friend got a water sample from Dal Lake, Srinagar. The ecosystem of Dal is ecologically rich with 117 recorded species of hydrophytes and phytoplankton. Here are some views of this beautiful Lake: wonder what we can find inside it, under the Foldscope! In my first observation, I saw many microbes…
AMAZING WORLD OF MARINE PLANKTONS – AN EXPERIMENTAL STUDY
Students of Artchouna Soupraya Naikar Government Middle School Mudaliarpet collected water samples from the Bay of Bengal using Plankton Nets and observed the Marine Planktons thro Foldscope and photographed it.

Green Algae
Closterium cells are crescent-shaped or elongate and lack spines. Some are quite straight and needle-like, while others are much broader with curved ends. The ends of the cell are usually tapered and may be pointed or rounded. Each semicell has a single axial, ridged chloroplast with at least one pyrenoid Place: SINGERBAND VILLAGE DIST. CACHAR…
Blue Green Algae
Anabaena is a genus of filamentous cyanobacteria that exist as plankton. They are known for nitrogen-fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern. They are one of four genera of cyanobacteria that produce neurotoxins, which are harmful to local wildlife, as well as farm animals and pets. Production…
Blue Green Algae
Scytonema is a genus of photosynthetic cyanobacteria that contains over 100 species. It grows in filaments that form dark mats. Many species are aquatic and are either free-floating or grow attached to a submerged substrate, while others species grow on terrestrial rocks, wood, soil, or plants. Scytonema is a nitrogen fixer, and can provide fixed…
Polluted Diatom
Surirella is a genus of diatoms in the family Surirellaceae. Place: SINGERBAND VILLAGE DIST. CACHAR (ASSAM) Date: 15/02/2019 Time: 12:16pm
Blue Green algae
loeothece Valve slightly sigmoid, linear-lanceolate, with subacute ends, 55-85 µm long, 8.5-12.5 µm wide. Raphe sternum with single curvature, raphe angle +4 to +8°, practically median throughout. Central raphe fissures oppositely deflected dimorphic crooks, difficult to see in LM. Terminal areas very small triangles in semilateral position. A small apical microforamina segment is present at…
Green Algae
Coelastrum Thalli forming 4, 8, 16, 32 or 64 (-128) celled coenobia to ca. 100 &m diameter, organized as spherical, pyramidal or cuboid, free-floating colonies. Cells more-or-less densely alligned but usually with empty spaces between wall interstices. Cells globose, ovoid, or pyramidal 2-30 &m in maximum dimension. Cells joined at edges by specialized wall plaques…
Blue Green
Oscillatoria is a genus of filamentous cyanobacterium which is named after the oscillation in its movement. Filaments in the colonies can slide back and forth against each other until the whole mass is reoriented to its light source. It is commonly found in watering-troughs waters, and is mainly blue-green or brown-green. Oscillatoria is an organism…
Fresh Water Diatom
Gomphonema Colonial cells that form on branched muscilage stalks that are attached to a subtrate. In girdle view the cells are wedge shaped with an enlarged head at the opposite end of the stalk. Cells have one large plastid that lye mostly on one side of the girdle, but do extend partially onto the other…
Fresh Diatom
Pinnularia is a predominantly fresh-water alga, usually found in ponds and moist soil. They can also be found in springs, estuaries, sediments, and oceans. Pinnularia are elongated elliptical unicellular organisms. Their cell walls are composed chiefly of pectic substances on a rigid silica framework. Their walls are composed of two halves called thecae (or less…
Freshwater Algae
Ulothrix is a genus of green algae in the family Ulotrichaceae. Ulothrix is a genus of filamentous green algae, generally found in fresh and marine water. Its cells are normally as broad as they are long, and they thrive in the low temperatures of spring and winter. They become attached to surfaces by a modified…
Studying post harvest loss in pea through foldscope
Lesions were seen on pea pods stored in refrigerator. The colour of lesions varied from translucent to brown. On observing these under foldscope, it appeared to be some fungus post-harvest loss in pea pods.
Foldscopy of green algae, Cladophora sp.
The Northern Sector of Chilika has tremendous amount influx of fresh water to the system and sheltering huge number of fresh water macrophytes and algae. During the ground survey of macrophytes in these area, dense growth of green algae was observed here. They were collected, mounted and observed under the Foldscope. The green algae were…
Capturing the internal structure of Cladocera under Foldscope.
Chilika lagoon is a unique assemblage of marine, brackish and fresh water ecosystem with estuarine characters. This fragile ecosystem is known for its amazing biodiversity. During sampling from the Nalabana,we observed the live movement of Cladocera under foldscope. Here in the video you can observe the heart beat & the intestine movement of the organism. The Cladoceran order of…
