Team Pagalapos: The mini-ecosystem at our door-step

How can we add location ,do we have to add it on stem chat or the cube chat

What if the well is dry ?? After adding water in the dry Well and then Taking the Sample … Can one find Ciliates or Other Organisms in it? @Mandar

The pagalapos as the name suggests started as system simulating the galapagos islands i.e. the isolated/partially isolated ecosystems at the doorstep. this could be an interesting model to study the island biogeography model of McAurthur and Wilson. The theory suggests that the species composition of the isolated island (pagalopos island) is determined by the immigration and extinction of species. The immigration and extinction depends on the distance between the islands as well as the size of the islands (interestingly the size here is more or less constant). Further each of these islands have their own array of environmental conditions would follow different evolutionary routes (as galapagos finches). This area of work although started in 1960s but is still matter of rigorous discussion among the scholars as SLOSS (Single large or Several Small) problem in ecology and conservation biology. In order to deal with this problem biologists are working on Large sized forest patches in Amazon forest for decades which is known as the Biological Dynamics of Forest Fragments Project ( BDFFP). (Which obviously involves lot of funds).

Cubists can deal with this problem with system as simple as Pagalopos !

Well the Galapagos and the Pagalapos relation is greatly explained by @Abhishek_Cube.
The ecosystem are studied in large forests, we can study in the small Pagalapos with large Ecosystem for microbes

@Mandar lets initiate a discussion of the Island biogeography theory in context of Pagalopos diversity at doorstep model.

Suppose I have a doubt If each pagalopos well have the same environmental condition then what will happen to the pagalopos in those two Wells @Abhishek_Cube @Mandar

Is there a possibility that two pagalopos Wells are same or may have same environmental conditions

What do you think what happens to the rotifers when the well is dry? @Kunal_Kadam

Even though the environmental conditions are the same. Mostly the organisms found in the wells are similar. But if two wells are far from each other. There can be chances of getting different types of organisms.

What is far we you are talking in case of microsorganism @Mandar

Like in Hbcsc campus, if we consider the environment conditions are same, if we collect sample from two different wells, there can be possiblity of getting different types of organisms

It is very unlikely to have same environmental conditions for two pagalopos wells even on the same manhole cover. they have different micro-environment. Something as shade and sunlight is huge difference of environment for bacteria or rotifer. Different leaf litter, some are dry some are wet. some have occasional bird droppings (which has seeds) at some there are visitors like squirrels, mosquitoes. No two such environments could ever be same.

Number of small Rotifers increased in 2nd well that is we are successfully making single line culture
We are able to see 3 more Small Rotifers
Although not able to take a video of that as they are not so stable

Although I did not find any reference of their life cycle But planning to study their life cycle by removing a small Rotifer from the second and see when they increase in number

What are the characteristics feature of rotifers? How can you say it a rotifers? First we have to know which rotifer it is then only we can proceed with the life cycle as life cycle will change or rather differ with species… And be specific about the search terms you are using for fetching out reference from Google baba :grin::grin::grin:

Well , I think they’ll Go in Dormancy ! @bivasnag

so can we check whether there is presence of rotifers in dry pagalopos or if they are absent how muh they take to appear to the already kept sample @Kunal_Kadam

I found two different larvae from the lid of a drainage cover near AC plant, HBCSE. The fast-moving is a mosquito larva. Don’t know what the other (bigger, black) is.

I also saw the mosquito larva under #foldscope
