Of these measures, the most popular is Shannon entropy (H). In this study, with respect to measuring biodiversity, we compare Shannon entropy-the essential aspect of information theory-with the Deng and improved Deng entropies, as proposed within the framework of the Dempster¨CShafer evidential theory. To do so, we used a hypothetical dataset of three complexes. Based on this hypothetic data, ecologically speaking, we obtained the most reasonable result from the improved Deng entropy. There are two reasons for this result: 1) Mass functions cannot be used when computing the Shannon entropy, and 2) Deng entropy does not take into consideration the scale of the frame of discernment
