There are four major structural and functional attributes of ecological succession, which are as follows: 1. There is an increase in structural complexity or the kinds of animals and plants change continuously with succession, no matter what is their taxonomic group. 2. The diversity of species tends to increase with succession. Increase in diversity of heterotrophs is especially striking. The [...]
Primary Succession: According to Clarke (1954), ecological succession that begins on a bare area where no life has existed, or where the previous flora and fauna have been completely destroyed, is known as the primary succession. If succession proceeds from an area devoid of organisms, or from an area which has not been changed physically by organisms, it is called [...]
According to Elton (1965), the animal succession may be best studied in very simple communities. It can be studied experimentally in the laboratory by making a hay infusion in water and leaving it open to the air for several weeks. Bacteria are the first organisms to become abundant, since they live upon the decaying vegetable matter. The various protozoan’s appear, [...]
