However, species richness increases with sample size. Though the geographical area cover of the country represents about 2.4% of the world’s total landmass, it harbours a total of 47,513 plant species (Singh & Dash, 2014) out of about 0.4 million hitherto known in the world, representing as much as 11.4% of world flora.

Functional diversity. Species evenness- is the abundance of the individual members within a particular species 4. Difficult to define because definition consists of two distinct components: i. Species Diversity: According to Biological Species Concepts (BSC), species is a basic unit of classification and is defined as a group of similar organisms that interbreed with one another and produce offspring’s and share a common lineage.

Species diversity depends as much on the genetic diversity as on the environmental condition. Such regulation of diversity requires maintenance of relatively constant levels of productivity and resource availability and an open system with opportunity for Ecological diversity. We try to gain insight to this paradox, by analyzing a simple model of a diverse community where each competing species inflicts a small mortality pressure on an introduced predator.

Species diversity reached its highest value in April (H'=2.34) in the 3rd station, and the Margalef species richness index value reached its highest value in the first station (D=3.84) in October. Beta diversity ($\beta$-diversity) is a measure of change in diversity between habitats or ecosystems and is thus a measure of spatial turnover of species. (Indices N1 and H' adj have not been included in the dendrogram). Furthermore, correlations between species diversity and habitat heterogeneity in different locations are subject to equilibrium and non‐equilibrium dynamics.
