Inspite of interspecific competition in nature, which mechanism the competing species might have evolved for their survival ?

Resource partitioning is a mechanism which has been used to promote co-existence among closely related species rether than exclusion. In MacArthur's studies, e showed that species of warblers living on the same tree avoided competition due to

Two closely related species competing for the same resouces cannot co-exist indefinitely and the competitively inferior one will be eliminated eventually. This is the conclusion of

Efficiency of capital has long been an area of neglect and remains so. This aspect is underscored in the eleventh plan draft, ironically in its demand for the rate of investment being raised to 35.1% of GDP from 29.1% in 2004–2005. The irony lies in the fact that the planning commission has consistently relied on the Incremental Capital Output Ratio (ICOR) as tool of expediency rather than one designed to promote efficiency. Yet, the ratio conceptually seeks to get the most out of the capital stock that is existing and is being added. The ratio now is 3.7, i.e the capital needed for an out-put of 1 is 3.7 times. If the effective ratio is brought down during 2007-2012, then it would be possible to achieve a GDP growth value of 8.9% over the period with a lesser level of investment than 35.1%. Nobody doubts that capital formation is critical to a higher rate of growth in GDP, but efficiency lies not so much on the capital stock as its utilisation. The present rate of investment is around 30% of GDP.
