Some of the common limiting factors of any water ecosystem are -  

a) turbidity,

c) pH level, and

Human activities have interfered with the water ecosystem adversely. The water pollution has affected all the limiting factors of river ecosystem .  

Addition of pollutants from industries and sewage system increase the turbidity of river water.  

The temperature of river ecosystem also increases because of the increased organic productivity of the rivers . This happens due to discharge of organic matter in river ecosystem.

pH are also destablised by addition of industrial and sewage effluents

And dissolved oxygen also reduced because of increased organic productivity of river ecosystem.

The comparatively fast evolution of various species from a single common ancestor is known as adaptive radiation. It usually takes place when an organism enters a novel region and distinct traits influence its survival. The island chain offers suitable conditions for adaptive radiation to take place as when an organism of a certain species comes to an island together and get disperse all through the chain, and each of these organisms getting settle into distinct niches and exploiting various food resources in order to minimize the competition, thus, resulting into adaptive radiation.
