Question

Identify and be able to use formulas to estimate species richness and species diversity.

Answer 1

Species richness and species diversity can be estimated using formulas such as Simpson's Diversity Index or the Shannon-Wiener Index. These formulas help quantify species richness and diversity, providing valuable information for biodiversity assessments.

Step-by-step explanation:

Species richness and species diversity can be estimated using formulas such as Simpson's Diversity Index or the Shannon-Wiener Index.

1. Simpson's Diversity Index (1 - D) takes into account both the number of species and their relative abundance. It is calculated as 1 - (sum of (ni/N)^2), where ni represents the number of individuals of each species and N represents the total number of individuals.
2. The Shannon-Wiener Index (H') measures the uncertainty of species identification in a sample. It is calculated as -sum(p(i) * ln(p(i))), where p(i) represents the proportional abundance of each species.

These formulas help quantify species richness and diversity, providing valuable information for biodiversity assessments.
