Which of the following is correctly matched?
$I$. Alpha diversity - Number of species in a given habitat
$II$. Genetic diversity - Variation of the genes within species
$III$. Beta diversity - Diversity of the habitat in the whole region
$IV$. Species diversity - Product of the species richness and evenness
$I$, $II$ and $III$
$I$ and $II$
$I$, $II$, $III$ and $IV$
$I$, $II$ and $IV$
Solution
$(i)$ Alpha diversity is the species diversity in a given community and habitat
$(ii)$ Genetic diversity is the diversity in number and types of genes as well as chromosomes present in different species and the variations in the genes and their alleles in the same species
$(iii)$ Beta diversity is the biodiversity which appears in a range of communities due to replacement of species with the change in community/habitat
$(iv)$ Species diversity is the variety in the number and richness of the species of a region. It is a product of species richness and evenness
