Summary
The significance of Liebig’s ‘Law of Minimum’ and Shelford’s ‘Law of Tolerance’ has been discussed. The environmental factors always act upon its inhabitants in a complex way.
From the field study it is difficult to single out a factor which could be responsible for the dominance of a given species or its complete absence.
Laboratory experiments have been conducted to study the reaction of different species of rotifers to thermal, pH and dissolved oxygen contents variations.
Platyias patulus has proved to be a true eurythermal species.Polyarthra multiappendiculata is very nearly the same. They can also withstand a wide variation in dissolved oxygen contents.
Present findings have been compared with those of other workers.
