The formula to calculate the Relative Abundance (RA) is:
\[ \text{RA} = \frac{\text{TS}}{\text{TP}} \times 100 \]
Where:
A relative abundance is a ratio of the total number of species in an area to the total population of all species in the area. In other words, it shows the proportion of the number of individual species to the total population.
Let's consider an example:
Using the formula to calculate the Relative Abundance:
\[ \text{RA} = \frac{50}{200} \times 100 = 0.25 \times 100 = 25\% \]
This demonstrates that with a total number of 50 species and a total population of 200, the Relative Abundance is 25%.
