Question

Difference between shannon wiener index and simpson diversity index

Answer 1

Answer:

Simpson's index is a similarity index (the higher the value the lower in diversity). If you want to use it as a diversity index you can subtract it to 1 (i.e. 1-S). Conversely, the value of the Shannon function (it is not an index) increases as diversity increases. The most used in phytoplankton ecology is probably the Shannon index because phytoplankton assemblages well fit the prerequisite of the function calculation (infinite population, sampled randomly)..
