WebFeb 1, 2003 · While it is fully termed the Shannon–Wiener function , after being derived independently by Claude Shannon and Norbert Wiener [10, 11, it is often called the Shannon–Weaver index after Wallace Weaver, Shannon's co-author. Recent papers of bacterial diversity have even named it the Shannon–Weiner or Shannon–Weaner index. WebThe Shannon-Weiner Diversity Index is a common way of showing that diversity involves not only numbers of different species, but also how well each of these species is represented in different habitats. The Shannon-Wiener index (H) indicates the degree of uncertainty of predicting the species of a

However, a non-significant impact of N addition on those variables has been widely reported (e.g., [16,17,19]), supporting our findings in this study. The lack of N addition ...
WebApr 11, 2024 · The Shannon–Wiener index includes richness and evenness and can therefore comprehensively reflect the diversity and evenness of the community (Wilsey and Stirling 2007). A larger Shannon–Wiener index means that there are more plant species in the community, and therefore, there is a higher species richness.
