There are many diversity indices you can use and you can chose the best one according to your research goal and question (among the most used you can find species or taxonomic richness or Eveness as the already suggested simpson or shannon index).

You can read more about diversity indices in the great book of Anne Magurran "Measuring biological diversity".

There are many you can use. There are descriptions and a discussion of the pros and cons of various diversity measures in Ch 12 of Ecological Methodology by Krebs (1997)

Yes, Shannon diversity index. I suggest this book: http://willcornwell.org/book-chapter-on-phylogenetic-diversity/

There are many diversity indices that can be applied in the measurement of wildlife diversity in a plantation. However, Simpson and Shannon-Wiener are the most commonly used. Shannon-wiener index ranges from 0 to infinity, while Simpson index ranges from 0 to 1. However, unlike the Shannon-Wiener index, Simpson index has an inverse relationship with diversity (i.e. the lower the index, the higher the diversity and vice versa. There are usually two ways to correct this inverse relationship to come up with an index that has a direct relationship with diversity. One way is to subtract the index from 1(i.e. 1 - D). Another way is to take the inverse of the index. The PAleontological STatistics (PAST) software can help you perform the computations.

Of great importance is a taxonomic group you assess diversity. If it's low fertility and low mobility - it is better to use a Shannon index. If you study the organisms that fast (poultry, fish) make better use of the Simpson index. It is more sensitive to vibrations with low quantitative difference in species composition. Then used when there are different ecosystems but many common species. Other codes should be avoided - it will be difficult to search the literature for comparison.

Dear Yonny,

You can try Shannon diversity index
