@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
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.
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
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
Today’s plan
Doing Serial dilution in order to make single line culture
One of our wells ( Serial dilution) got dried there was no Rotifer seen in the wells till 2 days after 2 days we saw Rotifer in the same plate but their movement was very slow
What do you mean was rotifers was not there? How does rotifer reappear like any super hero again after two days? What can be the scientific rationale behind this phenomenon @saida786110
todays plan
to make a mix culture of rotifers
they might be in the dormant stage
Bdelloids live 3 times as long, live in fine-grained environments and enter short-lasting quiescence as a direct response to changing environment. The two dormancy forms of the rotifers can be related to the temporal variation of their environments and seem to represent diverse responses to disturbance occurring at different rates. The two strategies are alternative and mutually exclusive, as no single rotifer species seems capable of both diapause and quiescence. Dormancy has great ecological significance: it can carry the population through stressful conditions, promote species coexistence and serve as a biodiversity bank providing reliable colonization source.
